Abstract
The utility model discloses an improved electric start petrol engine, which comprises a main body system, a crank connecting bar system, a fuel oil system, a cooling system and an air distribution system, wherein the main body system comprises a cylinder cover, a cylinder body, a crank shaft box, a silencer, a protecting cover and the like, the crank connecting bar system comprises a piston, a connecting bar, a crank shaft, a roller pin bearing, an oil seal and the like, the fuel oil system comprises an oil box, a switch, a filter screen, a sediment bowl, a carburetor and the like, the cooling system comprises a cooling fan, an induced air cover and the like, the air distribution system comprises an air inlet door, an air discharge door, a swinging arm, a push rod, a tappet and a cam shaft, and the output end of the crank shaft is provided with a start motor. Since the start motor is directly arranged on the output end of the crank shaft, the use of a clutch on the output end of the petrol engine does not need to change, the structure is reasonable and compact, and the starting property is excellent.
Description
Technical field
The utility model relates to a kind of miniature gasoline engine, especially relates to the miniature gasoline engine that a kind of electricity starts.
Background technique
Domestic existing small gasoline acc power can be divided into two-stroke and four-stroke generally at 0.63-24.00kW on structure.The characteristics of petrol engine are that volume is little and in light weight, use is easy and simple to handle, low price.Be mainly used in agricultural equipment for plant protection, graden machine, small machine, generator set, building machinery, fire-fighting series facility, amusement with kart, water-powered and model airplane power etc.For engine-driven knapsack sprayer, side-hanging type mowing machine, the indispensable especially mating power of miniature gasoline engine.Along with the purposes of petrol engine is more and more wider, also more and more higher to the startability requirement of petrol engine, at present, the startup method of petrol engine mainly contains two kinds, a kind of is artificial hand pull starting-up, is made up of start rope and simple starter cup, though method is simple, but purposes is restricted, another kind is exactly that electricity starts, though this startup method is more advanced, because the installation of starting electrical machinery is unreasonable, cause cost to increase, can not guarantee startability preferably.
Summary of the invention
The purpose of this utility model is exactly the above problem that exists in startup at existing petrol engine, provides a kind of improved electricity to start petrol engine, and this electricity startup petrol engine is rational in infrastructure, easy to operate, startability is good.
The purpose of this utility model is to realize like this, this improved electricity starts petrol engine and comprises airframe systems, the crank-connecting rod system, oil-fired system, cooling system, gas distribution system, described airframe systems comprises cylinder cap, cylinder body, crankcase, silencing apparatus, protective housing etc., described crankshaft rod system comprises piston, connecting rod, bent axle, needle bearing, oil sealing etc., described oil-fired system comprises fuel tank, switch, filter screen, sediment bowl and Carburetor etc., described cooling system comprises cooling fan, blower cover etc., described gas distribution system comprises into, exhaust valve; rocking arm; push rod; tappet and camshaft, described crankshaft output end is provided with starting electrical machinery.
The beneficial effects of the utility model: because starting electrical machinery is set directly on the crankshaft output end, need not change the use of petrol engine output terminal clutch, compactness rational in infrastructure, startability is good.
