Air mass meter

December 27th, 2011

Air conditioning systems are installed in cars so that driver and passengers can feel comfortable. It is really very essential that along with driving the car, you should be able to enjoy the comfort level as well. Air conditioning systems are built on a process through which humidity, motion, purity and temperature of air in enclosed areas can be controlled. This air is independent of all the external conditions. There are many components of air conditioning systems.

 

All these components are synchronized and they have to perform the important and specific task and functions too. Filters of air conditioning system comprises of larger capacity of dust holding. In fact, these are very low cost, they have longer life duration and can easily cleaned and installed too. All the parts of air condition systems are indispensable, but the most important part is air mass meter. This part will comprise of whole injection and fuel systems. You can find this component just in adjacent of air filters. These are present inside of engine components. The main role of air mass meter is to do the measurement of air. This will be done through hot meter equipments. Compressors are meant for cooling the heat present inside your car. The compressor of your engine is subjected to intense and a very high level of pressure and heat so as to cool its refrigerant and to produce out cool air. Condensers are the devices that are used for removing the water and vapors through air stream from the compressed air liners. It is very essential to remove all the contaminants from engine components.

Diesel Turbocharger

November 30th, 2011

A turbocharger, colloquially dubbed a ‘turbo’ is a centrifugal compressor. Compression of gases is brought about by a turbine, driven forced induction of engine’s exhaust gas i.e. exhaust gas recirculation. The turbochargers are popularly used with combustion engines e.g.: four stroke engines like ones with Otto and Diesel cycles. Diesel Turbocharger gains immense torque (even at lower rpm) and thus generate a lot of horse powers of energy without significant increase in the weight of the chassis, acting as boons in cutting down emissions and utilizing the gases masterfully to draw out the most of power thus maximizing fuel efficiency through tuned induction particularly in racing cars. They are useful in fuel cells where they are used with external combustion engines.
The turbochargers use the exhaust flowing from the engine to spin the respective turbines which in its turn spin the following air pumps. The turbochargers can spin at whopping speeds of up to 150,000 rotations per minute i.e. about 30 times as fast as a car’s engine can speed up to. Since it is linked to the exhaust, so the temperature in the turbochargers tend to shoot up by quite a big margin, which is why the cars are not sprinted for too long and only used primarily in racing.
In Diesel Turbocharger incidences of engine knocking or pre ignition or detonation may scavenge the efficiency of the engines. However technological advancement has led to inception of actuator controlled waste gates to relieve boosted pressure in the compressor unit to deal with discrepancies pertaining to enough heat/pressure occupying the engines.
