Power supply system scheme
On a shaft of the pump two plunzherny pairs submitting under a high pressure fuel to cylinders of the engine are established. Plunzhera receive progress at the expense of impact on them figured profile located in the pump. The amount of fuel submitted to cylinders is regulated by the batcher operated by a cable from a pedal of an accelerator. The corner of an advancing of injection changes depending on engine turns the mechanical centrifugal regulator which has been built in TNVD.
Two independent systems are applied to investment of start of the cold engine. One of systems at cold start-up supports the raised turns of idling, before engine warming up. It consists of a temperature-sensitive element established in a head of the block of cylinders, a cable in a cover and systems of levers on the fuel pump, On the cold engine the sensor tightens a cable, thereby, raising turns. When heating the working body of the sensor extends and releases a cable, thus on the heated-up engine the normal mode of idling is established.
The second system serves for improvement of ignition of fuel in cylinders at the moment of start-up. In vortical chambers of each cylinder glow plugs are established. Before engine start on them tension that shows fire of a control bulb on a combination of devices moves. Within several seconds of a candle are heated to high temperature and the control bulb dies away that serves as a signal for engine start. The heated candles lift temperature in the vortical chamber and facilitate fuel ignition. It should be noted that candles are disconnected not right after engine start, and after a while, allowing the engine to leave on a normal operating mode.
Failure even one candle conducts to the complicated start of the engine, with interruptions in work and strong vibration. The fuel system on diesel engines is usually very reliable. The main condition of normal and durable work is purity of used fuel and lack of water in it.
