The gear 40 of the generator-starter begins to rotate and through the ring gear rotates the flywheel 23, and with it the crankshaft 21. Four-stroke diesel engine starts and operates as follows. In the initial position (Fig.9) the upper and lower pistons 17 are located at the top dead point is (TDC). In the working chamber 25, the air is compressed and heated to a high temperature, the inlet 31 and outlet valves 35 are closed and through the nozzle 32 in her high-pressure pump 57 is injected fuel (arrow). Fuel from the high temperature in the working chamber 25 is ignited and the resulting gases generate pressure on the upper surface of the upper piston 17, which moves downwards, making a working stroke, and through the rod 19 causes to move down the lower piston 17, and the rod 20 rotates the crankshaft 21 in the direction shown by the arrow 180 degrees.
