Problems solved by technology

[0002] At present, when the engine is igniting or injecting fuel, the piston, connecting rod, and crank are almost in a straight line, and cannot form an effective torque on the rotation center of the crankshaft, so the engine consumes too much fuel and has low efficiency. Meet different working conditions and put forward the requirements for the use of automobiles

Abstract

The invention discloses a variable compression ratio engine. The variable compression ratio engine comprises a piston, connecting rods and a crankshaft, and is characterized in that the connecting rods include the upper connecting rod and the lower connecting rod; the upper end of the upper connecting rod is connected with the piston through a piston pin, and the lower end of the upper connecting rod is connected with a beam through a connecting rod pin; one end of the beam is connected with the upper end of the lower connecting rod through a left pin, and the lower end of the lower connecting rod is connected with the crankshaft through a connecting rod journal; the other end of the beam is connected with a control rod through a right pin, and the upper end of the control rod is provided with an elastic part. The output efficiency of the variable compression ratio engine can be effectively improved, and the purposes of increasing power and saving fuel oil are achieved.

Description

technical field [0001] The invention relates to a variable compression ratio engine. Background technique [0002] At present, when the engine is igniting or injecting fuel, the piston, connecting rod, and crank are almost in a straight line, and cannot form an effective torque on the rotation center of the crankshaft, so the engine consumes too much fuel and has low efficiency. The fixed compression ratio and cannot Satisfy the requirements for the use of automobiles in different working conditions. Contents of the invention [0003] The invention provides a variable compression ratio engine. [0004] To achieve the above object, the technical solution of the present invention is: [0005] A variable compression ratio engine, comprising a piston, a connecting rod and a crankshaft, characterized in that: [0006] The connecting rod includes an upper connecting rod and a lower connecting rod, the upper end of the upper connecting rod is connected with the piston through ...
