Diesel rotor engine

Abstract

The invention discloses a diesel rotor engine. The diesel rotor engine comprises a cylinder block and a rotor, wherein the rotor is 8-shaped; an eccentric shaft is arranged in the cylinder block; theouter side of the eccentric shaft is sleeved with a center gear; an inner ring gear is arranged in the rotor; the center gear is meshed with the inner ring gear; the inner space of the cylinder blockis divided into three working chambers by the rotor; and the volumes of the three working chambers are continuously changed along with the rotation of the rotor. According to the diesel rotor engine,the structure of a traditional piston engine is subverted, the structure is simplified, the size is reduced, and the mass is reduced; a complex auxiliary mechanical mechanism is removed, the manufacturing cost is reduced, power generated by combustion directly acts on the rotor, friction is small, rotation is smooth, and power output is efficient; and compared with an existing triangular rotor engine, the diesel rotor engine has the advantages that the rotor is changed into the 8-shaped rotor, a sealing device is arranged on the cylinder block, the sealing effect is good, abrasion resistance is higher, a high compression ratio can be achieved, and compression ignition can be conducted.

Description

technical field [0001] The invention relates to the field of automobile engines, in particular to a diesel rotary engine. Background technique [0002] At present, the known internal combustion engines include piston engines and rotary engines. In piston engines, the expansion pressure generated on the top surface of the piston pushes the piston downward, and the reciprocating motion of the piston drives the crankshaft to rotate and output power. The linear reciprocating motion of the piston The four strokes of air intake, compression, power and exhaust are completed with the switch of the valve. The traditional piston engine mainly has the following disadvantages: 1. Large volume and heavy weight; 2. Since the reciprocating motion of the piston drives the crankshaft to rotate, there are many auxiliary mechanical movements, large friction loss, and loud noise; 3. There are many parts, The structure is complex and the manufacturing cost is high. With a rotary engine, expans...
