Where is the Cummins engine throttle?

The throttle valve of the engine is located at the air inlet of the engine, behind the filter element of the engine air cleaner and in front of the intake manifold. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. The influence of throttle blockage is: 1, the vehicle is idling and it is not easy to ignite when it is cold; 2. It is easy to turn off the fire after quick oil collection; 3, resulting in increased fuel consumption and engine jitter. Precautions for using throttle: 1. Clean the throttle frequently. Too much throttle sludge will cause insufficient engine power and increase fuel consumption; 2. Before disassembly, oil the fixed metal ring to prevent the teeth from slipping.
