Non-round annular wheel crankless engines

Abstract

The invention provides a piston-typed engine without crankshaft, moment dead point, or time delay ignition, mainly comprising a cylinder body, a piston, a piston pin, a non-round internal gear, a mainshaft gear, a mainshaft, a cam, a cam roller, etc. When the piston supplies work, the piston pushes the non-round internal gear to move and pushes the mainshaft gear engaged with the non-round internal gear to rotate, and the power is output from the mainshaft; meanwhile, the other mainshaft gears are driven to drive respective non-round gear engaged with the mainshaft gear to move, in order to implement the working cycles of each cylinder of sucking, pressing, bursting, and discharging. As the thrust force of the non-round internal gear is always tangent to a reference circle of the mainshaft gear and the torque is not changed with the rotation angle of the mainshaft gear, the output torque of the mainshaft is improved to the most extent, the torque of the crankshaft is avoided to be changed with the rotation angle of the crankshaft, the work loss caused by moment dead point and time delay ignition are avoided; the conversion rate of the power can theoretically reach 100%; the output torque, the output power of the mainshaft and the power performance of the engine are greatly improved, and the fuel consumption and pollution discharge are reduced by more than a half.

Description

technical field [0001] The invention relates to an internal combustion engine which utilizes a non-circular internal gear to realize reciprocating motion to perform work. [0002] Widely used in internal combustion engines including various gasoline engines, diesel engines, piston air compressors, and piston refrigeration compressors. Background technique [0003] Existing internal combustion engine is basically crankshaft connecting rod piston engine (except turbine engine, rotary engine). However, the crank-slider mechanism composed of crankshaft, connecting rod and piston has many fatal weaknesses in the conversion of work: [0004] Disadvantage 1 The crankshaft output torque M changes with the crankshaft angle , that is, when the piston thrust P is the largest, the crankshaft output torque M is the smallest, and there is a dead point.
