Problems solved by technology

[0003] In the prior art, the center of the crankshaft dot of the piston engine is located on the vertical centerline of the cylinder. The rotation of the crankshaft causes the connecting rod to produce a flexible and symmetrical swing arc. The piston is pushed by the connecting rod to reciprocate in the cylinder. When the crankshaft rotates to 90 degrees, the crankshaft torque and the inclination angle of the connecting rod are at the maximum value, and the lateral horizontal force generated by the piston is also the largest. At this time, the piston group will generate greater friction with the connecting rod bearing and the cylinder wall, resulting Loss of power, reduced fuel efficiency

Abstract

The invention discloses a piston type engine offset crankshaft connecting rod mechanism which comprises an air cylinder, a piston, a connecting rod and a crankshaft. The centre line of the crankshaft is arranged deviating from the vertical center line of the air cylinder, and offset quantity L is 9-12mm. In the offset range, side force acted on the piston in the work stroke can be effectively reduced, lateral pressure of the piston to the side of the air cylinder can be reduced, and consumed energy caused by friction between the piston and the wall of the air cylinder can be reduced correspondingly. Heat efficiency of a combustion engine is improved, and the service life of the air cylinder and the service life of the piston can be prolonged. Due to the offset arrangement of the crankshaft, stroke of the piston is increased, work time of the piston is prolonged, sufficient burning of fuel is benefited, more useful work can be obtained under the same combustion condition, and economic efficiency of fuel oil is improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to a piston engine offset crankshaft connecting rod mechanism. Background technique [0002] The crankshaft connecting rod mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion, and it is the power transmission system in the reciprocating internal combustion engine. In the power stroke, it converts the thermal energy generated by fuel combustion into mechanical energy from the reciprocating motion of the piston and the rotational motion of the crankshaft, and outputs power to the outside. [0003] In the prior art, the center of the crankshaft dot of the piston engine is located on the vertical centerline of the cylinder. The rotation of the crankshaft causes the connecting rod to produce a flexible and symmetrical swing arc. The piston is pushed by the connecting rod to reciprocate in the cylinder. When the crankshaft rotates to 90 d...
