dodge - The history of petrol engines may be dated all the way back to the 19th century if the first single cylinder engine was designed. 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 greatest innovation to be incorporated into petrol engine design was done 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 in this design have triggered a system which has replaced carburetors in modern petrol engines. This computerized set up is known as an Engine Control Unit also it consists of an array of sensors utilized to monitor various engine performance parameters.

Engine control units found in modern cars are responsible for monitoring and operating every purpose of an internal combustion engine, from changing the valve timing to manipulating 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 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 and also the timing of the spark ignition. Unlike other ECUs, which may have a fixed number of engine parameters and mainly control the quantity and air and fuel that adopts 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 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 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 also the Mass air flow sensor to find out the amount of air that's being sucked in to the engine and adjusts the quantity of fuel accordingly. This not merely provides a substantial increase in power, but it also increases the economy of the vehicle. Utilizing this ECU, Chrysler features a new technology referred to as 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 with out sacrificing any power by opting for a smaller engine.

The chrysler 300, engine control unit is also capable of eliminating engine "knocking". Engine knock is the phenomenon in which the petrol undergoes combustion prior to being ignited by the spark plugs, and thus, knocking can cause a great deal 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 of the fuel. The Chrysler 300m engine control module greatly increases the power, fuel economy and efficiency from the engine and the effectiveness of this device is evident from the widespread adoption
