Problems solved by technology

[0007] 1. The effective power of the combustion and explosion force of the piston needs to be converted to the output and input of the crankshaft and flywheel through the connecting rod, and the remaining power is transmitted to the mechanical structure in the form of torque. In the end, the useful power has been lost too much
[0008] 2. The stroke inertia force of the piston and connecting rod and the explosion vibration force have a great impact on the crankshaft, resulting in great noise and vibration
[0009] 3. The ratio of the stroke inertia of the piston connecting rod to the inertia of the flywheel crankshaft is very small. To manufacture a connecting rod piston internal combustion engine with a large cylinder diameter, it is necessary to manufacture a large diameter crankshaft and a large enough flywheel. For example, the crankshaft of a large ship connecting rod piston internal combustion engine is small Tens of tons each, the largest crankshaft reaches 300 tons and a 14-cylinder, and the required materials are relatively high in terms of strength, toughness, rigidity, etc., so it is difficult to manufacture in this country

Abstract

The invention discloses a crankshaft connecting rod piston internal combustion engine with a combustion chamber arranged in a piston. The crankshaft connecting rod piston internal combustion engine comprises a cylinder body, the piston, a crankshaft, an air distribution system, a cooling system, a lubrication system and a fuel feeding system. The piston and the crankshaft are arranged in the cylinder body. At least one pair of piston connecting rods connected with the piston symmetrically, crankshaft connecting rods in rotating connection with the piston connecting rods and the crankshaft, an auxiliary cylinder cavity arranged in the piston and a plunger arranged in the auxiliary cylinder cavity are further included. According to the technical scheme, by multi-connecting-rod switching buffering, vibration and impact force on the crankshaft from the piston are lowered, noise is greatly lowered, the plunger in the piston solves the structure technical problem that the reciprocating impact force of the piston and the connecting rods is directly exerted on a compressed stroke is solved, and the structure is wide in applicability and can be used for improving of most connecting rod internal combustion engines.
