Background

The fuel acting part of the traditional gasoline engine only accounts for about 30% of total combustion energy generally, namely the thermal efficiency of the gasoline engine is about 30%; the thermal efficiency of the diesel engine is slightly high, about 40%. In addition, around 35% of the energy is carried away by the engine cooling system, and the remaining approximately 35% of the energy is carried away by the engine exhaust. If the combustion work-doing efficiency of the combustion cylinder of the engine can be improved, the efficiency of the engine can be improved, so that the oil consumption of the engine is reduced, and the emission of greenhouse gases is reduced. Therefore, how to improve the working efficiency of the engine is a problem that has been attracting attention.

the invention provides an engine with double combustion chambers and capable of fully mixing combustible gas, which comprises a combustion cylinder, an inlet valve and a piston in the combustion cylinder, wherein the combustion cylinder is internally provided with two combustion chambers which are distributed at two ends of the piston in the combustion cylinder, the two combustion chambers are respectively provided with the inlet valve, strip-shaped grooves are symmetrically arranged at two sides of the combustion cylinder, the piston is fixedly connected with a pair of parallel piston connecting rods through the strip-shaped grooves at the two sides of the piston, the piston connecting rods slide along the length direction of the strip-shaped grooves, two ends of the combustion cylinder are respectively provided with a rotating shaft, the rotating shaft is connected with a spring-shaped spiral stirring rod extending to the piston, the other end of the spiral stirring rod extends into the piston, the piston is provided with a corresponding spiral hole corresponding to the spiral stirring rod, and the piston connecting rods are connected with a power output.

Preferably, the piston rod is fixed to the piston in a clamping manner through a clamping groove. So that the piston rod and the piston are firmly and detachably connected.

Preferably, a cross bar is connected between the parallel piston connecting rods, and the cross bar is connected with a crankshaft of the crank-connecting rod mechanism. The power of the piston can be output in a rotary mode through the structure.

The invention has the beneficial effects that: in this engine, when the gas in the combustion chamber at one end is combusted, the expanding gas pushes the piston toward the other end, the gas in the combustion chamber at the other end is compressed, and when the piston reaches a limit position, the gas in the combustion chamber is ignited to be combusted, and the piston is pushed toward the other end to reciprocate in a cycle. The combustion cylinder both sides are equipped with the bar groove, and when the piston was in extreme position, the edge of piston did not reach bar groove department to prevent combustion chamber gas leakage, the spiral puddler that the swivelling joint at combustion cylinder both ends was connected can rotate at piston reciprocating motion's in-process, makes the combustible gas in the combustion chamber mix more evenly. Therefore, the invention can lead the combustible gas in the combustion chamber to be mixed more uniformly through the structure of the double combustion chambers and the structure of the spiral stirring rod in the combustion chamber, and has higher combustion efficiency, and the structure of the double combustion chambers can lead the output efficiency of the engine to be higher.
