Choke valves restrict airflow to create a better fuel-air mixture in engines. Modern vehicles use fuel injection systems, but some still use choke valves. Manual or automatic control is possible, and newer engines use superchargers or turbochargers to create pressure. Choke valves were commonly used in automobile engines until the late 1980s. Choke valves help […]
A throttle body controls airflow in a fuel-injected engine and does not provide fuel in the air mixture. It measures air according to how far the accelerator pedal is pressed and uses fuel injectors to provide fuel. Throttle position sensors may be used to measure fuel passing through the injectors. The throttle body requires occasional […]
