Scheme of a power supply system
On a shaft of the pump two plunger couples giving under high pressure fuel to engine cylinders are established. Plungers receive progress due to impact on them of the figured profile located in the pump. The amount of the fuel given to cylinders is regulated by the batcher operated by a cable from an accelerator pedal. The corner of an advancing of injection changes depending on engine turns the mechanical centrifugal regulator which is built in TNVD.
Two autonomous systems are applied to investment of start of the cold engine. One of systems at cold start-up supports the raised idling turns, before warming up of the engine. It consists of the thermal sensor installed 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, at the same time on the heated-up engine the normal mode of idling is set.
The second system serves for improvement of ignition of fuel in cylinders at the time of start-up. Glow plugs are installed in vortex cameras of each cylinder. Before start of the engine on them tension moves that it shows fire of a control bulb on a combination of devices. Within several seconds of a candle are heated to high temperature and the control bulb dies away that serves as a signal for start of the engine. The heated candles lift temperature in the vortex camera and facilitate fuel ignition. It should be noted that candles are disconnected not right after start of the engine, and after a while, allowing the engine to come to a normal operating mode.
Failure even of one candle leads 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 the used fuel and lack of water in it.
