In this regard, how does a diesel throttle work?
The throttle on a gasoline engine is typically a butterfly valve. When the throttle is partially closed, a manifold vacuum develops as the intake drops below ambient pressure. The power output of a diesel engine is controlled by regulating the quantity of fuel that is injected into the cylinder.
Furthermore, what are the symptoms of a bad throttle body? When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle. This can include stalling when coming to a stop or very low idle after starting, or even stalling if the throttle is quickly pressed (resulting in the throttle body plate opening and closing very quickly).
In this regard, does a diesel have a throttle body?
Diesel engines don't need a throttle body. Engine RPM is controlled by the amount of fuel injected, as well as minor changes in injection timing. (although it could be said that a turbocharger helps to control air flow) One problem that arises from not having a throttle body is that there is no vacuum source.
How does the throttle body work?
On a fuel-injected engine the throttle body is normally located between the air filter and the intake manifold, and is connected to the gas pedal mechanically with a cable, or electronically by wire. When the driver presses the pedal the butterfly in the throttle body pivots to let more air flow into the manifold.
