Background technique
Petrol engine is to act as a fuel with gasoline, with chemical energy change into kinetic energy motor.Because gasoline viscosity is little, evaporation is fast, can gasoline be sprayed into cylinder with gasoline injection system, after overcompression reaches certain temperature and pressure, uses spark ignitor, makes gas expansion for doing work.The characteristics of petrol engine are that rotating speed is high, simple in structure, quality is light, cheap, smooth running, easy maintenance.At present, during gasoline engine starting on market, mostly come the enriching fuel mixture to improve the startability of petrol engine by increasing chock plate on Carburetor, and this petrol engine startability is low to a certain extent, need to operate chock plate during startup, and misoperation is higher.
Summary of the invention
Deficiency for above-mentioned prior art exists the objective of the invention is to be to provide a kind of startability high, and not needing to operate chock plate can directly start, and the reduction of large limit the petrol engine of misoperation start system without the automatic enriching of chock plate fuel mixture.
For realizing above-mentioned purpose, the technical solution adopted in the present invention is: a kind of petrol engine starts system without the automatic enriching of chock plate fuel mixture, petrol engine is provided with the starting drive of petrol tank, motor and ato unit, be fixed with the auxiliary fuel injector device on described starting drive, the oil inlet pipe of described auxiliary fuel injector device is connected with petrol tank, oil outlet tube is connected with the Carburetor of motor, is respectively arranged with one-way cock on described oil inlet pipe and oil outlet tube.
The present invention further is set to: described starting drive starts or manually boots for electricity, and the described concrete structure that manually boots is: be provided with the hand pull starting-up rotating disk of ato unit and the handle tray that is installed on the hand pull starting-up rotating disk below described petrol tank; It is to start with starting electrical machinery that described electricity starts.
The present invention further is set to: the structure of described auxiliary fuel injector device is: be provided with rubber ball in the groove that arranges on the housing of described handle tray or starting electrical machinery, the oil inlet pipe of rubber ball is connected with petrol tank, oil outlet tube is connected with the Carburetor of motor, be provided with the projection of pressing described rubber ball on the motor shaft of described hand pull starting-up rotating disk or starting electrical machinery, rubber ball is rotated and pushed to the rotation drive projection of the motor shaft of hand pull starting-up rotating disk or starting electrical machinery is the interior gasoline supercharging of rubber ball.
The present invention further is set to: be provided with the enhancing rubber ball identical with the curvature of described rubber ball at the arc plate of this place's intensity on the rubber ball at described projection extruding rubber ball place.
By adopting technique scheme, the technique effect that the present invention reaches is:
1, the present invention can make petrol engine significantly improve startability, need not operation chock plate when starting, only need directly to start, when starting petrol engine, by the auxiliary fuel injector device, the moment compression through the auxiliary fuel injector device is come as oily supercharging enriching, the startability of motor significantly to be promoted take this;
2, the present invention reduces the air inlet amount with respect to original technology, and is simple in structure to increase air fuel ratio, and starting performance of gasoline engine also significantly improves, and starting torque obviously increases, and can reduce to greatest extent misoperation.
