A highly fuel-efficient engine

Abstract

The invention discloses a highly oil-saving engine. According to the highly oil-saving engine, gas is ignited and explodes when the force arm length between a connecting rod and a crankshaft is large, then a high force moment generates on the crankshaft and simultaneously a high gas compression ratio is maintained. The highly oil-saving engine comprises an air cylinder, a main piston, the connecting rod, the crankshaft, sparking plugs and an oil nozzle, wherein the main piston does reciprocating movements in the air cylinder, the connecting rod is connected with the main piston, the crankshaft is driven by the connecting rod to rotate, and the sparking plugs and the oil nozzle are located in the air cylinder. An auxiliary piston which is used in cooperation with the main piston to do up-down reciprocating movements as the main piston is arranged above the main piston in the air cylinder. The sparking plugs and the oil nozzle are located between the main piston and the lower dead center of the auxiliary piston. Compared with the prior art, the highly oil-saving engine has the advantages that the highly oil-saving engine is of the double-piston structure that the auxiliary piston is additionally arranged above the main piston so that the high gas compression ratio can be maintained when the main piston in the air cylinder moves downwards; the gas is ignited and explodes when the force arm length between the connecting rod and the crankshaft is large, then the high force moment can generate on the condition of low oil consumption, and consequently the purpose of saving oil is achieved.

Description

technical field [0001] The invention relates to a fuel-burning engine, in particular to a highly fuel-saving engine that efficiently utilizes fuel explosion thrust in the engine cylinder, can adjust the compression ratio, and can use various fuels. Background technique [0002] There is only one movable piston in the current fuel engine cylinder, which reciprocates in the cylinder and turns into a rotating power output through the connecting rod and crankshaft mechanism. It consists of four working strokes: air intake, compression, ignition and explosion, and exhaust. Among them, when the piston moves to the top dead center of the cylinder, the gas is compressed to the smallest volume, that is, the compression ratio is the highest. At this moment, the explosion thrust generated by the gas ignited will be the largest, but at this time the connecting rod and the crankshaft that drive the piston are in a straight line In general, the length of the moment arm between the connect...

Problems solved by technology

Among them, when the piston moves to the top dead center of the cylinder, the gas is compressed to the smallest volume, that is, the compression ratio is the highest. At this moment, the explosion thrust generated by the gas ignited will be the largest, but at this time the connecting rod and the crankshaft that drive the piston are in a straight line In general, the length of the moment arm between the connecting rod and the crankshaft is very small, or even zero, so the torque obtained on the crankshaft is very small, so the ignition can only be delayed properly. When there is a certain moment arm length between the crankshafts, re-ignite to increase the torque to push the crankshaft, which will inevitably reduce the compression ratio of the gas volume and make the fuel efficiency low
