The PT fuel system is a patented product of Cummins Engine Company of the United State. Compared with the fuel system of a typical diesel engine, the PT fuel system has its own unique features in composition, structure and working principle.
When the diesel engine starts, the crankshaft does not turn or rotate slowly when it rotates, so that the diesel engine can not enter the self-operating state. There are generally three reasons. Firstly, the battery is insufficient, the starting resistance is tool large, or the movable contact and the static contact of the electromagnetic switch are burned. Secondly, poor contact. Thirdly, the specific inspection methods are as follow:
The DC motor is the motive force of the output torque, and most of its structures use a four-pole series-excited motor. Such a motor has a large output torque at a low speed and a strong overload capability.
In principle, the intake, compression, work and exhaust processes of the genset diesel engine are started or completed when the piston reaches the top dead center and reaches the bottom dead center. However, in order to make the intake more fully, the exhaust is cleaner, and the intake and exhaust valves should be opened early and delayed.
