The power supply system scheme
On a pump shaft two are established плунжерные steams submitting under a high pressure fuel in cylinders of the engine. Плунжеры receive progress at the expense of influence on them of a figured profile located in the pump. The quantity of fuel submitted to cylinders is regulated дозатором, an operated cable from an accelerator pedal. The corner of an advancing of injection changes depending on engine turns the mechanical centrifugal regulator which has been built in in ТНВД.
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 gauge tightens a cable, thereby, raising turns. At heating the working body of the gauge 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 candles накаливания are established. Before engine start on them pressure that shows fire of a control bulb on a combination of devices moves. Within several seconds of a candle are heated to a heat 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 is necessary to notice that candles are disconnected not right after engine start, and after a while, allowing the engine to leave on normal operating conditions.
Failure even one candle conducts to the complicated start of the engine, with faults in work and strong vibration. The fuel system on diesel engines is usually very reliable. The basic condition of normal and durable work is cleanliness of used fuel and absence in it of water.
