Description
The utility model relates to a kind of motorcycle engine, particularly relates to a kind of two-stroke motorcycle motor that adopts electronic fuel injection.
Motorcycle is one of important traffic tool, and the usage quantity present motorcycle engine that increases sharply has two kinds of forms, i.e. two stroke engine and four stroke engine, two stroke engine is simple in structure, cost is low, and rate of fault is little but to exist oil consumption big, shortcoming such as exhaust pollution is serious.Oil consumption causes the serious waste of the energy greatly, and befouling environment brings infringement so old-fashioned two stroke engine that the trend that is eliminated is gradually arranged can for people's physical and mental health.Four stroke engine complex structure, production technology and cost requirement height.But oil-saving effect is good, and is little to the pollution of environment.
The purpose of this utility model, be at the problems referred to above provide a kind of simple in structure, cost is low, oil consumption is little, the two-stroke motorcycle motor that befouling environment is little.
The purpose of this utility model adopts following technical proposals to realize, that is:
The two-stroke motorcycle motor of electronic fuel injection comprises that crankcase, bent axle, cylinder, piston, connecting rod, suction tude, air filter, air pressure balancer, transport pipe, fuel tank, outlet pipe, electrical control oil spray pump are gentle, oil ratio electronic controller and ignition detector cylinder be fixed on the crankcase upper end.The cylinder cap of cylinder is provided with isolating high-pressure ignitor.Piston is arranged in the cylinder and connects with bent axle by connecting rod.Ignition detector is fixed on the outer wall of crankcase.The rear end of suction tude is connected with cylinder.Air filter and air pressure balancer are installed on the air inlet pipeline.One end of outlet pipe is connected with cylinder.Fuel tank is connected with electrical control oil spray pump by transport pipe.The front end that it is characterized in that electrical control oil spray pump stretches in the crankcase; Cam is housed on bent axle, and when bent axle drove cam rotation, cam can contact with the electrical control oil spray pump core; The cylinder cap of cylinder is provided with oil sprayer, and the front end of oil sprayer is positioned at cylinder; On air inlet pipeline, be equiped with Air flow meter, on Air flow meter, be equiped with the temperature-sensitive plug, to record the gas temperature that enters cylinder.Gas, oil ratio electronic controller are connected with ignition detector with magnetic coil, Air flow meter, temperature-sensitive plug, the isolating high-pressure ignitor of electronic oil injection pump by lead respectively, with control air and oily proportions of ingredients and high voltage ignition.
During use, bent axle rotates and drives the cam rotation that is contained on the bent axle, when cam touches the pump core of electrical control oil spray pump, just driving pump core reach makes pump be in opening state, meanwhile, the air mass flow of band temperature-sensitive plug measures air mass flow and the temperature that enters cylinder, through gas, the computing of oil ratio electronic controller, make electrical control oil spray pump export best oil mass, and through oil sprayer oil spout in cylinder.This moment ignition detector receive the fire signal (the magnetogenerator flywheel walks to top dead center) of the magnetogenerator flywheel that is fixed on the bent axle, by the igniting of gas, oil ratio electronic controller controls.
The oil spout angle design of the utility model motor is in piston stroking upward oil spout during with exhaust close, oily direct cylinder injection and air mixing burning.The proportions of ingredients of its air and fuel under the control of gas, oil ratio electronic controller, reaches the optimum state, has given play to maximum power.In addition, what the utility model was inhaled in suction stroke is pure air, so motor can make the lubricating system of splashing, and lubricant oil can not burn in cylinder, has reduced the pollution of exhaust to air, and has prolonged the working life of motor.
The utility model has kept the characteristics that former two stroke engine is simple in structure, cost is low, has four stroke engine joint and the little advantage of befouling environment again, and is practical
Fig. 1 is a kind of example structure schematic representation of the present utility model.The utility model is described in further detail below in conjunction with accompanying drawing.
