How Do Auto AC Systems Work

wisnu — Mon, 05 Mar 2012 15:13:57 +0000

In the days of ole, the wind was the best way to keep a hot day from being too much to bear but the modern age calls for a modern solution. AC systems are designed to cool off air and keep the environment cool, well the indoor environment that is. Ever stood near the outside of an AC system, that heat has got to go somewhere. AC parts such as an A/C compressor and evaporator work together not to eliminate heat but to move heat to a different location. The Idea of the ac system is simple, capture heat on a medium and use fluid to move said heat to another location. In the case of an auto ac system the heat is captured from the evaporator inside the car, usually under the dash. The captured heat is transferred to the condenser at the front of the vehicle and released.

A car, unlike a home relies more on moving air than fans to pull the heat off the condenser at the front of the vehicle. Auto AC is also a much more compact version of what a home ac system is…unless you feel like strapping a window unit into your car. When a car is in movement, air is blowing across the condenser which is basically a radiator that uses coolant and a cooling fan. Just like the engine cooling system that keeps the car from over-heating the ac system keeps the passenger from overheating.

Components in the AC system play vital roles, each doing something that will specifically change the way the system works. The compressor being most important part, as it pushes the fluid through the system so that each of the other components can do their job. There is also a filter in the system that is often called a Accumulator/Drier which is designed to remove dirt and debris from the system. Then the fluid is passed through the condenser to be cool and yep you guessed it condensed. Once the Oil/Freon mix is cooled than it is passed through the expansion device where the fluid is allowed to expand into larger tubing. This process will further cool the fluid and then it is pushed into the evaporator which is a device where the fluid will be spread out even more onto what is like a radiator but works in reverse. Once the fluid travels across the evaporator a fan pushes air across it and the heat in the air is removed by the super-cooled liquid. Finally the heat soaked liquid is pulled back through the system and it all starts again. Ac systems are designed to make life more comfortable and cooler for all of us even if a failing system may make us a bit hot headed.

What is a Throttle Position Sensor?

In order for your car to work properly everything must beworking in prime condition. Fromsomething as big as a diesel turbo charger to something as small as a throttleposition sensor, if one thing is malfunctioning your car will feel theeffects. We all know what car parts suchas an AC Compressor does, but a lot of us can get confused when we start totalk about all these sensors. I thoughtI would help you out a little bit and explain what a one of these sensors does.

Present day vehicles have an assortment of diverse sensors. Whenit comes to these sensors the key is “knowledge is power.” The sensors supply the knowledge to the computer so that the computer knows how much power needs to be out. One such sensoris the Throttle Position Sensor. Thislittle guy is located on the intake butterfly on internal combustion engines. The throttle position sensor is apotentiometer that reports to the computer in regards to how open the throttleis. This valuable info combined withdata from different sensors is used by the ECU to determine the correct fuel amount,ignition timing, and other important tasks. In turbocharged vehicles, the throttle position sensor’s cherishedinformation assists the wastegate for better car performance.

A malfunctioning Throttle Position Sensor means that thecomputer is not getting the correct information it needs to work properly. This means the computer, the brain of yourcar, has lost a lot of its brain cells. Your car may start to jerk, suddenly stall, and hesitate whileaccelerating, and the fuel economy will plummet. So, make sure your brain is getting the rightinformation so you’re not blowing a bunch of cash at the gas station. If your Throttle Position Sensor is brokenfix it immediately.

Saturn Compressor AC Line Update

wisnu — Thu, 01 Mar 2012 16:42:23 +0000

Over the years there are updates to parts just like thereare to car models. For every model year that a vehicle is in production thereare small changes that are more than skin deep. The AC compressor just like other automotive AC parts may change as the years go by. Sometimes a car company goes under andthe aftermarket has to take over the production of the replacement parts. Inthe case of Saturn that is exactly what happened, when the company closed itsdoors it left many of its vehicles owners out in the cold when it came toparts. Maybe out in the cold is the wrong term to use, out in the heat isbetter since the OEM AC compressor was no longer available the aftermarket didwhat it could.

The solution to the lack of supply was to find a compressorthat bolted into the same location as the original Saturn compressor. This isnice in theory but the problem arose when a compressor was found, the compressorcould bolt on but the AC lines would not hook up. The solution was found injust changing them out and sending the update out whenever a Saturn L series orVue compressor was sold.

Each one of the replacement compressors was sold with a setof the high and low side ac lines what could be easily swapped into the system.This simplistic fix is a great example of how the aftermarket is not just abunch of cheap parts but more a community of vendors who are working to createa market for anything that has a need.

Saving Some Change at the Pump

wisnu — Tue, 14 Feb 2012 13:07:25 +0000

Gasoline charges are on the rise yet again and that signifies it is time for all of us to commence pondering of techniques to preserve a handful of cents for each mile. Of program there is usually checking the fuel pump and gas level sender on the fuel pump assembly but there are plenty of other tricks to aid get some added mileage out of our cars. The effectiveness of a vehicle is based mostly on the way it is generate and the excess weight it has to haul about.

Very first just take a search at what is in the vehicle aside from you since anything that adds fat is one thing that losses mileage because of to additional fat. With a trunk entire of products or a back again seat full of clutter can add a excellent a hundred lbs to the vehicle and that will price you more than time. Beneath inflated tires can charge cash about time, the alter in resistance from the tire against the highway surface area alterations the performance. Every single car on the street has been created to be as productive as possible with the gas it was created for. Even though a lot of individuals feel they will get far better mileage by using high quality fuel, it is just not genuine. If your auto was developed to use 89 octane and it will run worse with 91 or 93, and vise versa. Use the correct fuel in your motor vehicle to attain highest effectiveness.

There is a prevalent saying in the gear head entire world and it operates well for fuel savings as properly. Do not upgrade the car, up grade the nut behind the wheel. Generally it indicates if you would like to save fuel alter the way the auto is driven. Although it may be exciting to quit the gas and take off like a rocket at each light, it is confident as hell not the most efficient. Conversely incredibly sluggish acceleration will waste materials fuel as nicely owing to the time that the motor is in an advanced rev assortment. The very best factor to do is locate a gradual acceleration level which uses the lease gasoline and even now gets the car safely to journey velocity. In no way sacrifice basic safety in the quest for gas cost savings but a few further feelings about it are adequate to help save hundreds more than the course of the yr.

Clean Fuel Injectors Mean Better Gas Mileage

wisnu — Mon, 13 Feb 2012 07:18:55 +0000

After time you may notice your car isn’t getting the same gas milea

ge it once did. A cause of this may be one of your diesel injectors, which can experience wear over time. Diesel or regular fuel injectors will need a bit of work to sustain the power and performance they had from stock. In some cases a simple cleaning of the injectors can restore the vehicle’s performance. In other cases, the diesel injectors may need to be replaced with a new diesel injector kit. A recent consumer reports study shows that 46% of people think fuel economy is the most important factor when purchasing a car. (Have you seen any Hummers around lately?) The only factor that seems to have more of an impact on new car sales is price.

A main factor that can hurt the performance of a fuel injector is dirt. A fuel injector is basically a valve controlled by the car’s ECU. This valve opens and closes very quickly to allow fuel to be squirted into the intake valves. Ideally, the fuel is delivered as a mist and it is vaporized immediately. If there is any dirt on the nozzle or within the injector itself, the fuel will not be sprayed as consistently and the combustion system will suffer. This process takes place in small fractions of a second and is therefore extremely sensitive.

How do you clean your fuel injectors? Give them a bath! Ultrasonic cleaning is one of the more intensive (but effective) solutions. This process involves actually removing the injectors and giving them a “bath” in a special cleaning solution. Simpler cleaning tips include doing a few full throttle accelerations on the highway. After having the injectors cleaned, most car drivers notice an immediate improvement in performance.

If there has been too much dirt buildup or there are other problems facing the fuel system, the fuel injectors may ultimately need to be replaced. If it comes to this, you should probably consider changing out all of the fuel injectors at the same time. So save yourself some money at the pump this holiday season and make sure your getting the gas mileage you’re suppose to!

Time for an Oil Change?

wisnu — Sun, 12 Feb 2012 18:33:51 +0000

If your oil alterations are costing shut to $ one hundred possibilities areyour engine requires synthetic oil. The metal components of your vehicle (suchas steering racks and steering gearboxes) want oil to keep lubricated, butthere is a lot more than one type of oil accessible. Most automobiles get conventionalor all-natural oils which are derived right from crude oil. This oil has manynatural properties which protect and lubricate the engine more than lengthy durations oftime.

A downside to normal oil is that it is made up of manyimpurities such as sulfur which can slow down the movement of oil during theengine. Over time contaminants can also create up and produce deposits or waxwithin the engine. &nbspWith this in mind, syntheticoils had been produced with specific chemical attributes in order to create a moreconsistent material. Even though organic oils can break down quickly at extremelyhigh temperatures, artificial oils are made to withstand this heat. There areeven synthetic oil blends created for particular reasons these as lubricating ahigh-functionality or substantial-mileage automobile. Regardless of its larger price, synthetic oiloffers the rewards of enhanced lubrication, greater stability, diminished oilbreakdown and fewer deposits.

Even so, just since synthetic oils supply these rewards does not meanthat you need to switch up the form of oil at your subsequent oil adjust. In mostcases conventional oil does the occupation just fine synthetic oil is only requiredfor specific autos. If you are pondering of changing up your oil be certain tocheck with your producer before-hand for vehicle-particular suggestions. &nbsp

A Clogged Air Filter Can be a Dangerous Enemy

wisnu — Sat, 11 Feb 2012 00:49:49 +0000

There are a lot of hurdles on the street in front of all of us…literally. Cars, timber, youngsters enjoying in the street and the occasional mudslide but some of the most significant types are inside of our own car. Plenty of troubles rob our autos of horse energy and efficiency. Cars work in a tolerance of anything operating appropriately to accomplish appropriate mileage and overall performance. Wheel hub bearing should not offer you also considerably resistance and the gas pump must be functioning with enough pressure, essentially every little thing make the automobile run the way it should. Individuals are likely to about seems to be fundamental servicing and really don’t understand that even the smallest issue can lead to a massive issue.

Oil alterations can indicate the difference amongst a motor enduring 10K miles and 300K miles, whilst transmission fluid changes can lengthen the lifestyle of the tranny. The air filter is one particular of these components that folks are likely to disregard but not understand what a filter can do. Believe about respiratory by way of a straw, could you operate a mile like that…well that is what your car is doing with a clogged filter. A clogged air filter robs horsepower and gas mileage and can also trigger difficulties in large efficiency cars. With restricted air flow in turbocharged vehicles this can trigger un-needed strain preventing the turbocompresseur. This stress can cause the oil in the turbocompresseur to leak from the device or it can lead to a reduction of the proper air consumption quantity. This can trigger incorrect combustion in the cylinders and even lead to injury to the bottom finish of the motor.

Why Should a Visual Inspection be done on your vehicle

wisnu — Sat, 11 Feb 2012 00:49:47 +0000

Vehicle and trucks are just like folks when it comes to wellness problems. Failure of an alternator or the starter can be noticed months in advance just like the indications of a critical disease in a particular person. Numerous moments the indications for a auto can be seen by just taking a close seem or hear.

The tires are the very first area to examine if the tread don is diverse on every single tire or if the don is unusual on a single tire there might be far more of an concern then the wheel itself. A peculiar use pattern on a tire can indicate a negative alignment, bent handle arm, bad bushing or something even even worse. These issues can all be detected with a easy visible inspection which can help save hundreds or 1000′s of dollars.

There are other areas that can be visually inspected this kind of as the brakes or the motor by itself. The brakes will demonstrate signs if there are likely to be foreseeable future issues, these indications can be as easy as grooving on the discs or leaking from the caliper or lines. Proper brake treatment is critical given that they are what sluggish the 3000lbs piece of metal that we all get all around in.

When inspecting the motor it is a very good idea to appear at all the belts and check for intense cracks or places of the motor in which there is oil leakage. If a belt have been to snap in a motor not only will the car have to be towed to a repair shop but if it ended up to be the timing belt that was to snap it may damage the motor. Leaking from gaskets in the motor is a sure signal that some interest requirements to be paid to that location. Leaking of oil or coolant will at some point lead to failure if not addressed and can be really pricey to the owner of the automobile.

There are a lot of programs in a car and realizing what to check for can be the finest preventive upkeep. Repairing an issue just before it comes about will always conserve income and time plus staying away from the headache that will inevitably stick to any critical automotive breakdown.

Get Rid of that Squeal from under the Hood

wisnu — Sat, 11 Feb 2012 00:49:45 +0000

There are lots of noises that come with functioning a vehicle, from the hum of the gasoline pump to the whine of a supercharger. The whistle of the turbocharger or the peaceful roar of the tires on the pavement they are all appears we get accustom to. The 1 audio that is typical that most of us are not able to stand is a belt squeal. The sound is developed either by the belt in the groves of the pulleys in which it rides. There are a number of different leads to can be linked with the source of the squeal. When the audio comes after a rain or driving by means of a huge puddle it signifies that some of the water has arrived at the again of the belt and is creating slippage which is the supply of the audio.

Belt squeals are triggered by the belt not becoming restricted adequate and slipping on the pulley, when the rubber of the belt slides on the pulley it causes the audio. A massive problem on this is that the belt will use more quickly and could snap leaving the drive of the motor vehicle stranded.

Belts turn into loose for a few causes in a vehicle, a single is that above time the belt has stretched because of to pressure. One more issue can be physical motion of the belt pushed component itself, all belt push accessories are bolted to the motor on sliders. If the bolts that maintain these units turn into unfastened the belt pressure will decrease and slippage will arise.

Belt squeals can be fixed in a quantity of methods, a new belt can be put in and the problem will be solved even though this can be high-priced at instances. The much more well-known remedy is to just basically tighten the belt, this is a simple procedure of loosening the bolts that maintain the accessory creating the audio and shifting the unit till the belt is restricted. Then secure the bolts and the sound must be stopped, it is critical to not over tighten the belt as also a lot pressure can cause the belt to snap. As with all vehicle maintenance it is essential that this be accomplished properly by somebody who is aware of that they are doing. With proper attention a automobile can previous nicely into the fifty percent million mile marker without key troubles.

What Does a Knock Sensor Do?

wisnu — Sat, 11 Feb 2012 00:49:44 +0000

Knock sensors are the units in cars that check the pinging in the motor and assist management the timing of the engine. The personal computer utilizes the input from the knock sensor along with the O2 sensors and air gas ratio sensor to alter the timing and gas combination in the pistons.

The motor in a modern motor vehicle has to be held in excellent timing to guarantee the top of effectiveness and overall performance. This is completed by toeing the line in between operating excellent and detonation. The best ignition of the air / fuel mixture comes about at the exact instant that the aide is about to attain the top rated of its stroke. The timing is set this way to make sure the pressure has time to start pushing the piston back down. When the spark plug is fired with the incorrect ignition timing or gas combination the strain waves move out from the flame wall more rapidly than the explosion itself. When this takes place they influence the side wall at the incorrect time and a sound wave is produced and detected. The component in the knock sensor is created to detect this sound and notify the pc to change the timing.

All sensors in a motor vehicle are really critical and are usually neglected on fundamental upkeep. Throughout automotive test ups it is crucial to remember to examine the smaller sized areas this sort of as sensors and filters to make sure defense from future problems.
