[http://www.stjeromechryslerdodgejeepram.com/ dodge] - The history of petrol engines could be dated all the way returning to the 19th century when the first single cylinder engine was designed. This also marked the integration from the "carburetor" into the design of automotive engines. Further improvements inside the design resulted in multi cylinder petrol engines, however, the best innovation to be integrated into petrol engine design was over in the 80's by BMW when they created a system which controlled the fuel injection, air flow and the ignition sparks of the engine. Further refinements and iterations on this design have led to a system which has replaced carburetors in modern petrol engines. This computerized set up is known as an Engine Control Unit plus it consists of an array of sensors used to monitor various engine performance 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's injected based on a number of different parameters, the ECU is widely considered the brain 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.

[http://www.stjeromechryslerdodgejeepram.com/ jeep] - The Chrysler 300m ECU is in charge of 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, that have a fixed number of engine parameters and mainly control the amount and air and fuel that goes into the combustion chamber, the Chrysler 300m ECU can be a highly advanced control module and it is able to control an enormous array of engine parameters to improve the power and efficiency from the engine. The Chrysler 300m ECU is really a sophisticated computerized device which monitors the engine performance and adjusts it in accordance with predefined performance maps stored around the onboard chip from the ECU. The Chrysler 300m ECU communicates with the throttle position sensor and the Mass air flow sensor to determine the amount of air which is being sucked into the engine and adjusts the quantity of fuel accordingly. This not only provides a substantial boost in power, but it also improves the economy of the vehicle. Utilizing this ECU, Chrysler has introduced a new technology called cylinder deactivation which basically involves shutting off several cylinders of the engine once the vehicle is cruising. This technological innovation not allows for huge fuel savings without sacrificing any power by opting for a smaller engine.

The [http://www.stjeromechryslerdodgejeepram.com/ 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 therefore, knocking can cause a lot 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 increases the power, fuel economy and efficiency of the engine and the effectiveness of this device is evident looking at the widespread adoption
