What is mass flow?
A "mass airflow" sensor, measures the amount of air entering an engine to properly calculate the amount of fuel that is needed.
Is the mass air flow sensor the same as idle control valve?
No, the MAF measures the amount of air entering the engine, while the idle control valve controls the amount of air at idle.
What does the idle control valve do?
It controls the amount of air entering the engine when the throttle is closed, controlling the idle speed..
Where is the mass air flow sensor on a 2000 Daewoo Lanos located?
The mass air flow sensor is located directly in the engine compartment. The MAF measures the temperature of the air and the amount of air entering the engine.
How do Electric fuel injection system work?
When you step on the pedal, the throttle valve opens to allow entry of air. The engine control unit increases the fuel rate to allow more air into the engine. Sensors monitor the amount of air entering the engine.
What is a air intake filter?
An air intake filter is what blocks dust particles from entering into you engine. It is an air purifier which cleans the air your engine takes in.
What is the job of the idle air control valve on a Chevy impala 2001?

What do the turbos in diesels do?
Increase the amount and pressure of air entering the cylinders.
What does an air flow mass sensor do on a motor car?
Measures to amount of air entering the intake
What causes a diesel to idle?
Diesels run on compressed fuel and air. An injector pump sprays fuel into the cylinder and mixes it with the air. When the piston rises to the top of the cylinder it compresses the fuel / air mixture and causes the mixture to ignite powering the engine. The speed of the engine is controled by the throttle plate which controls the amount of air entering the engine as well as the metering valve on the diesel pump which controls the amount of fuel that is sprayed into the cylinder.
What pressurizes the air entering the intake manifold to improve the engine performance?
Supercharger
What is the function of after cooler in diesel engine?
To cool the charge air before it entering to the cylinder.
