Four-piston cylinder engine

Abstract

The invention provides a four-piston cylinder body spin engine, comprising a shell, a rotor type cylinder body and a crankshaft, wherein the rotor type cylinder body is sheathed in the shell and can rotate relative to the shell; the crankshaft is inserted in the shell; the invention is characterized in that the inner wall of the rotor type cylinder body, which is along the circumferencial direction, is provided with four cylinders which are directly cross, each cylinder is provided inside with a piston, a interlocking bar is pivotally arranged between each two adjacent pistons, four interlocking bars are same in length; one of pistons is pivotally connected with a connecting rod which has the other end pivotally connected with the crankshaft of the engine, the crankshaft is connected with the cylinder body by a gear set and kept to rotate with reverse direction and equal angular velocity; the shell is provided with an air inlet, an igniter and an air outlet. When the crankshaft turns a circle, the cylinder body also turns a circle along the reverse direction, the four cylinders all complete the four stroke operating cycle of air intake, compression ignition, do-work and air exhaust once, thereby realizing the effect of big output power.

Description

technical field [0001] The present invention relates to the internal combustion engine structure, in particular to a piston cylinder rotary engine. Background technique [0002] The cylinder block of the traditional piston reciprocating internal combustion engine is fixed, and the piston pushes the connecting rod to drive the crankshaft to rotate. When four-stroke movement is realized, the crankshaft must rotate two weeks, that is, 720°, to complete a cycle. To form multi-cylinder action, the crankshaft must be increased. Arranged along the axial direction of the crankshaft, a complex structure of the gas distribution mechanism is required at the same time. Due to the structural characteristics, the traditional piston reciprocating internal combustion engine has a large structure, weight, and large vibration and noise during operation (only one cylinder can be installed on the same section). The shortcomings of small output, while the triangular rotary engine saves the valve...
