dodge - The history of petrol engines may be dated all the way returning to the 19th century once the first single cylinder engine was made. This also marked the integration from the "carburetor" into the design of automotive engines. Further improvements within the design resulted in multi cylinder petrol engines, however, the maximum innovation to be integrated into petrol engine design was over in the 80's by BMW after they created a system which controlled the fuel injection, ventilation and the ignition sparks with the engine. Further refinements and iterations in this design have resulted in a system which has replaced carburetors in modern petrol engines. This computerized system is known as an Engine Control Unit plus it consists of an array of sensors accustomed to monitor various exhaust parameters.

Engine control units present in modern cars lead to 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 your brain of modern automobiles. The Chrysler 300m ECU is located at the rear of the engine bay, at the back 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, which may have a fixed number of engine parameters and mainly control the amount and air and fuel that adopts the combustion chamber, the Chrysler 300m ECU is a highly advanced control module and is also able to control an enormous array of engine parameters to boost the power and efficiency of 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 also the Mass air flow sensor to determine the amount of air that's being sucked in to the engine and adjusts how much fuel accordingly. This not just provides a substantial boost 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 several cylinders of the engine if the vehicle is cruising. This technology not allows for huge fuel savings without having to sacrifice any power by deciding on a smaller engine.

The chrysler 300, engine control unit can be capable of eliminating engine "knocking". Engine knock is the phenomenon in which the petrol undergoes combustion before being ignited by the spark plugs, and as such, knocking can cause significant amounts 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 of the fuel. The Chrysler 300m engine control module greatly raises the power, fuel economy and efficiency with the engine and the effectiveness of the device is evident from the widespread adoption
