Does the EFI diesel vehicle have a throttle? What is the function of the throttle?

1, the throttle is what we often say (gasoline engine). Its function is to control the amount of mixed gas entering the cylinder. It is installed in the appropriate position of the intake manifold and connected to the accelerator pedal with a metal wire. When driving, the driver's "refueling" or "draining" actually changes the throttle opening (changing the amount of mixed gas entering the cylinder) to accelerate or decelerate the car.

2. It should be pointed out that gasoline engines have both valves and throttles, while diesel engines have only valves and no throttles. The change of the accelerator pedal of diesel vehicle can accelerate or decelerate the vehicle by controlling the injection quantity of high-pressure oil pump.
