FIELD: engines and pumps. ^ SUBSTANCE: diesel engine contains cylinders and covers with interior lining composed of composite ceramic elements. Pistons of the diesel engine are also made of composite ceramic elements, while mounting piston skirts are installed through gaskets in metal boxes containing piston rings. The boxes are connected to a crank gear mechanism. Ends of cylinder composite linings facing the axis of a crank shaft, ends of metal boxes facing the cylinder composite lining and cylinder interior surfaces form closed spaces each containing two bypasses with back valves installed into them. A receiver is mounted on the diesel engine; the said receiver via a pipeline is coupled to one of the bypasses with a back valve of each cylinder, while the second bypass with a back valve of each cylinder communicates with air. Boosting branches of each cylinder are connected to the receiver. Cylinders and cylinder covers interior linings can be arranged with a gap against the metal cylinder and the cover. There is a heat exchanger installed in the diesel engine, this exchanger by means of the heat of exhaust gases heats air flowing to cylinders. Separators-oil extractors are installed into pipelines connecting one of bypasses with the back valve to the receiver. ^ EFFECT: increased reliability of operation. ^ 3 cl, 3 dwg |
