dodge - The history of petrol engines can be dated all the way back to the 19th century when the first single cylinder engine was designed. This also marked the integration of the "carburetor" into the design of automotive engines. Further improvements in the design resulted in multi cylinder petrol engines, however, the best innovation to be incorporated into petrol engine design ended in the 80's by BMW once they created a system which controlled the fuel injection, air flow and the ignition sparks with the engine. Further refinements and iterations in this design have triggered a system which has replaced carburetors in modern petrol engines. This computerized device is known as an Engine Control Unit and it consists of an array of sensors used to monitor various exhaust parameters.
Engine control units found in modern cars have the effect of monitoring and operating every function of an internal combustion engine, from changing the valve timing to controlling the amount of fuel that is injected based on a a few different parameters, the ECU is widely considered the mind of modern automobiles. The Chrysler 300m ECU is situated at the rear of the engine bay, at the rear of the center of the dashboard.
jeep - The Chrysler 300m ECU accounts for controlling the various parameters of internal combustion engines like the air/fuel mixture, the valve timing as well as the timing of the spark ignition. Unlike other ECUs, that have a fixed number of engine parameters and mainly control the total amount and air and fuel that switches into the combustion chamber, the Chrysler 300m ECU is really a highly advanced control module and is also able to control a vast array of engine parameters to enhance the power and efficiency with the engine. The Chrysler 300m ECU is a sophisticated computerized device which monitors the engine performance and adjusts it according to predefined performance maps stored around the onboard chip from the ECU. The Chrysler 300m ECU communicates with the throttle position sensor as well as the Mass air flow sensor to determine the amount of air which is being sucked in to the engine and adjusts the amount of fuel accordingly. This not just provides a substantial boost in power, but it also improves the economy of the vehicle. Utilizing this ECU, Chrysler features a new technology called cylinder deactivation which basically involves shutting off several cylinders of the engine when the vehicle is cruising. This technological innovation not allows for huge fuel savings without sacrificing any power by deciding on a smaller engine.
The chrysler 300, engine control unit can also be capable of eliminating engine "knocking". Engine knock will be the phenomenon in which the petrol undergoes combustion prior to being ignited by the spark plugs, and as such, knocking can cause significant amounts of damage to the engine. However, once the Chrysler 300m ECU detects an imminent knocking effect, it adjusts the valve timing and delays it by a few milliseconds in order to avoid premature combustion from the fuel. The Chrysler 300m engine control module greatly improves the power, fuel economy and efficiency with the engine and the effectiveness with this device is evident from its widespread adoption
