Engine Throttle Control System

For most of the 20th century throttle control involved a direct mechanical connection between your accelerator and the engine.

Engine throttle control system.

The electronic throttle control system within most vehicles is constructed with three important parts. The accelerator pedal the throttle valve and a control module or pcm. These controls provide single lever control for clutch and throttle from two stations and are available in single and twin engine configurations. Throttle control systems for controlling petrol and diesel engines for vehicles include the so called drive by wire system in which there is no mechanical linkage between a driver actuated accelerator pedal or cruise control command switch and a mixture controlling system such as one or more carburettors or a fuel injection system.

The ecm is a type of electronic control unit ecu which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors including the accelerator pedal position sensors engine speed sensor vehicle speed sensor and cruise control switches.

A basic automotive control problem is to maintain a desired engine speed despite the torque disturbances due to power steering air conditioning or engagements of automatic transmission. About the throttle control system. The main actuation scheme is by controlling the amount of air supplied to the engine via a throttle bypass valve. The throttle control unit is necessary to ensure that you get the optimum amount of power from your engine.

The electronic throttle control system is the inner workers of the engine that signals the throttle when the pedal is pushed. An engine control unit ecu also commonly called an engine control module ecm is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. But as emissions control and fuel economy regulations became more strict computers were developed to provide more precise metering of the air fuel mixture that goes into the engine. Alternatively the throttle valve will open slightly if you are only driving to keep the air fuel mixture at the optimum level.
