In a diesel engine, fresh air is sucked into the cylinders where it is highly compressed. Due to this, the temperature in the cylinders rises above the ignition temperature of diesel fuel. When the piston is close to its top dead center and the air is highly compressed and heated to about 600°C, diesel fuel is injected. The ignition of the fuel occurs on its own. That is, spark plugs are not required here.
What often happens on a very cold engine is that the compression does not provide ignition temperatures. In this case, the engine needs to warm up. For this, a glow plug is installed in each vortex chamber. preheating combustion chamber. In addition, the diesel engine has a cold start acceleration device, which is controlled by the traction button, the injection regulator piston of the high pressure fuel pump moves about 2.5°in the direction of the earlier injection. This allows hot air to be injected earlier and a cold engine to start more easily. As soon as the engine warms up to its operating temperature, it is necessary to completely drown the thrust button.
In this chapter, only the features of repairing a diesel engine are given. All other operations are similar to the petrol engine and should be viewed in previous chapter.
