Abstract
The utility model discloses a novel energy -concerving and environment -protective petrol engine, including cylinder body and spark plug, be equipped with bent axle and piston in the cylinder body, the bent axle is located under the piston, bent axle and piston rotate with the connecting rod respectively to be connected, be equipped with the valve directly over the cylinder body, the valve is by valve tip, valve axle journal and valve connecting rod composition, the spark plug is established in the middle of the valve. The utility model discloses the engine, increases spiracular tip thickness and has further promoted the compression ratio in order to obtain better compression ratio through improving crank throw and connecting rod length, has lengthened spiracular life simultaneously, and the gasoline engine compression ratio that finally makes reaches more than 10, has guaranteed the abundant burning of petrol for the efficiency of engine reaches about 40%, and just used technique can be used to the transformation of current engine, reforms transform rear engine vigorous, and is energy -concerving and environment -protective, has fine use value.
Description
Technical field
The utility model relates to a kind of engine, is specifically related to a kind of novel energy-saving environment-friendly petrol engine.
Background technology
Existing reciprocating engine acting principle is by the reciprocating motion of piston rod, and the acting of the piston of cylinder of internal-combustion engine or steam engine is converted to and rotatablely moved by the cooperation of connecting rod and bent axle, is used for driving crank acting. When piston in I. C. engine is positioned at top dead center position, the space that top land and cylinder cover inner surface form becomes combustion chamber. This spatial volume is called combustion chamber volume. Piston moves to from top dead centre the spatial volume that lower dead center passes through and is called displacement volume, and when piston is during at bottom dead center position, whole volumes of cylinder on piston top top are called cylinder total volume. Cylinder compression ratio is the ratio of cylinder total volume and combustion chamber volume, it is the parameter of weighing gas compressed degree in cylinder, compression ratio is larger represents that gas degree by compression in cylinder is larger, the pressure and temperature of compression terminal gas is higher, power is larger, but compression ratio can not be too high, otherwise easily there is phenomenon of detonation. Compression ratio is to affect one of engine power very key factor, and most petrolic compression ratios are between 6 ~ 10 now, and its power is lower, is only 25 ~ 30%, and room for improvement is huge.
Current most people improve compression ratio and engine performance by changing top land shape, but it is less to change effect, also there is people to improve by improving crankshaft-and-connecting-rod length, but without improvement scheme and the parameter of specification, cause the engine failure after change to take place frequently, have larger potential safety hazard.
Utility model content
In order to address the above problem; the utility model provides a kind of novel energy-saving environment-friendly petrol engine; valve, crankshaft-and-connecting-rod length are optimized; gained engine compression ratio parameter is good; the burning of gasoline is more abundant; improve engine efficiency, reduced the discharge of unburned gas, protected environment.
The utility model is achieved through the following technical solutions:
A kind of novel energy-saving environment-friendly petrol engine, comprise cylinder body and spark plug, in described cylinder body, be provided with crankshaft and piston, described bent axle is positioned under piston, described crankshaft and piston is rotationally connected with connecting rod respectively, directly over described cylinder body, be provided with valve, described valve is made up of valve end, the gentle door of valve axle journal connecting rod, and described spark plug is located in the middle of valve.
Further, the thickness of described valve end is 1 ~ 2.5mm.
Further, when the radius of described bent axle increases r length, length of connecting rod increases (25 ~ 35) % × r length.
Further, the compression ratio of described engine is 10 ~ 15.
The utlity model has following beneficial effect: the utility model engine is by improving crank throw and length of connecting rod to obtain better compression ratio, the end thickness that increases valve has further promoted compression ratio, extended the service life of valve simultaneously, the gasoline engine compression ratio finally making reaches more than 10, ensure the abundant burning of gasoline, make the efficiency of engine reach 40% left and right, and technology used can be used for the transformation of available engine, transformation rear engine is powerful and vigorous, energy-conserving and environment-protective, have good use value.

Detailed description of the invention
A kind of novel energy-saving environment-friendly petrol engine, comprise cylinder body 1 and spark plug 6, in described cylinder body 1, be provided with bent axle 2 and piston 4, described bent axle 2 is positioned under piston 4, described bent axle 2 and piston 4 are rotationally connected with connecting rod 3 respectively, directly over described cylinder body 1, be provided with valve 5, described valve 5 is made up of valve end 51, valve axle journal 52 and valve connecting rod 53, and described spark plug 6 is located in the middle of valve 5.
Further, the thickness of described valve end 51 is 1 ~ 2.5mm.
Further, when the radius of described bent axle 2 increases r length, connecting rod 3 length increase (25 ~ 35) % × r length.
Further, the compression ratio of described engine is 10 ~ 15.
The manufacture thickness that the utility model has provided valve end 51 is 1 ~ 2.5mm, exceed 40 ~ 50% than common valve, dwindle the size of cylinder 1 end space when piston 4 is positioned at top dead centre, promote efficiency of combustion, bent axle 2 radiuses and connecting rod 3 length have been carried out to the adjustment of rational proportion simultaneously, can stablize the compression ratio that promotes engine, security and the stationarity of its operation are ensured again, made petrol engine compression ratio is 10 ~ 15, more than improved efficiency to 40%, has good use value.
