What does a throttle chamber do?
Overview of the Throttle Body The throttle body is designed to control the amount of air that enters the combustion chamber. You can usually find it located between the air intake manifold and the engine air filter, which ultimately connects to your vehicle’s engine.
What does an electric throttle body do?
The throttle body is designed to control the fresh air of spark ignition engines in combination with an electronic throttle control system. ETB applications with flex-fuel, CNG and LPG are permissible if injected in the air flow after the throttle body.
How does the throttle work on an electric car?
The throttle can open and close according to the instructions from the electric motor. Sensors in the throttle called the throttle position sensors (TPS) will then communicate with the engine management system to let it know it is in the correct position. At the core, the throttle body controls the amount of air that flows into the engine.
What are the parts of the 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.
What does an electronic throttle body look like?
When electronic throttle control first appeared, it was accompanied by its own ETC module. Practically all modern vehicles have integrated electronic throttle control into the engine control modules (ECM), simplifying installation, programming, and diagnosis. An electronic throttle body looks like a typical throttle body.
What does electronic throttle control ( etc ) mean?
Throttle body with integrated motor actuator Electronic throttle control (ETC) is an automobile technology which electronically “connects” the accelerator pedal to the throttle, replacing a mechanical linkage.
How does the electronic throttle control system work?
Additionally, if the vehicles onboard electronic system communicate properly, the computer can control all of the engine’s operations. Most importantly, for the safety of the driver, with actuators and sensors in place, the engine receives the correct information from the throttle opening.
Which is more expensive cable or electronic throttle control?
Electronic throttle control is more complex and more expensive than old cable-driven systems, but it tends to last longer—at least a decade. Still, there are a few symptoms that could indicate a problem in the ETC system.
When did BMW start using electronic throttle control?
In 1988, the first “drive-by-wire” electronic throttle control (ECT) system appeared. The BMW 7 Series was the first to feature an electronic throttle body (ETB). The electronic throttle control system includes the accelerator pedal, ETC module, and throttle body.
Where is the air control located in a throttle body?
The primary control on airflow is governed by the throttle plate. However, there might be additional valves for air to flow as well such as an idle air control valve. A typical throttle body also includes a throttle position sensor, which is usually located adjacent to the throttle linkage, inside the main casing of the throttle body.
