How ECM controls your car and its importance in the car's functionality.
1. In-Cylinder Air-Fuel Ratio Control. The In-Cylinder Air-Fuel Ratio Control is a more efficient way of maintaining air-fuel mixture in comparison to the conventional method of managing air-fuel mixture. The exhaust emission can be reduced by reducing the nitrogen oxide emission and unburned hydrocarbon emissions, while improving fuel consumption at the same time! Worlddieselservices.com is the ECM,s dealers providing new original and remanufactured ECM,s. 2. Exhaust Gas Recirculation. The ECM's job is to measure the oxygen content in the exhaust gases, the coolant temperature and pressure in the engine, the throttle position, etc., and use this information to adjust one or more of your car's emission control systems (such as the EGR valve and catalytic converter) so that they work with maximum efficiency. 3. Spark Timing. Spark Timing is an ECM for cars, which manages the air-fuel mixture and regulates emission control systems. It also features a built-in Bluetoo...
