dodge - The history of petrol engines can be dated all the way returning to the 19th century if the first single cylinder engine was made. This also marked the integration with the "carburetor" into the design of automotive engines. Further improvements inside the design resulted in multi cylinder petrol engines, however, the greatest innovation to be integrated into petrol engine design was done in the 80's by BMW after they created a system which controlled the fuel injection, air flow and the ignition sparks from the engine. Further refinements and iterations on this design have resulted in a system which has replaced carburetors in modern petrol engines. This computerized set up is known as an Engine Control Unit and it consists of an array of sensors used to monitor various engine performance parameters.
Engine control units present in modern cars are responsible for monitoring and operating every function of an internal combustion engine, from changing the valve timing to governing the amount of fuel that is injected based on a number of different parameters, the ECU is widely considered the mind of modern automobiles. The Chrysler 300m ECU is found at the rear of the engine bay, at the rear of the center of the dashboard.
jeep - The Chrysler 300m ECU is responsible for controlling the various parameters of car engines like the air/fuel mixture, the valve timing as well as the timing of the spark ignition. Unlike other ECUs, which 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 a highly advanced control module and is able to control a vast array of engine parameters to enhance the power and efficiency from 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 on the onboard chip from the ECU. The Chrysler 300m ECU communicates with the throttle position sensor and the Mass air flow sensor to find out the amount of air that is being sucked into the engine and adjusts the amount of fuel accordingly. This not only provides a substantial increase in power, but it also raises the economy of the vehicle. Utilizing this ECU, Chrysler has introduced a new technology referred to as cylinder deactivation which basically involves shutting off a few cylinders of the engine once the vehicle is cruising. This technological innovation not allows for huge fuel savings with out sacrificing any power by choosing 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 before being ignited by the spark plugs, and as such, knocking can cause a great deal of damage to the engine. However, when the Chrysler 300m ECU detects an imminent knocking effect, it adjusts the valve timing and delays it by a number of milliseconds in order to avoid premature combustion with the fuel. The Chrysler 300m engine control module greatly raises the power, fuel economy and efficiency with the engine and the effectiveness of this device is evident from the widespread adoption
