Description
Technical field
The utility model belongs to motorcycle with electronic fuel injection system fuel nozzle oil spout technical field, specifically, is specifically related to the installation combination of a kind of intake manifold and fuel nozzle.
Background technique
Existing motorcycle with electronic fuel injection system all is that intake manifold is installed on the intake duct, intersection in motor and firing chamber forms a valve storehouse, be fixed with fuel nozzle near on the intake manifold in this burner port valve storehouse, fuel nozzle sprays into intake manifold with gasified fuel, and at the movable installation in the valve storehouse of motor valve, valve is connected on the valve stem, work along with each stroke of motor, valve stem pulling valve moves at valve Cang Chu, realize the folding of air inlet of combustion chamber, when motor enters suction stroke, valve breaks away from the valve storehouse, air inlet of combustion chamber is opened, and the negative pressure in the firing chamber sucks motor with gasified fuel in the intake manifold and air.At other strokes, valve falls in the valve storehouse and closes air inlet of combustion chamber.
But the shortcoming of prior art is: fuel nozzle just is fixed on the intake manifold simply, perhaps towards intake manifold or towards valve and valve stem or towards motor, its injection time is also without control, after valve is blocked the firing chamber import often, fuel nozzle is also in oil spout, at this moment, oil gas often is injected on intake manifold inwall and the valve stem, forms the wet wall phenomenon of intake manifold.
The model utility content
For solving above technical problem, the purpose of this utility model is to provide a kind of intake manifold and fuel nozzle that combination is installed, when the engine chamber mouth is opened, can guarantee that the oil gas of fuel nozzle ejection can both directly be admitted to engine chamber, avoid the generation of the wet wall phenomenon of intake manifold.
The technical solution of the utility model is as follows: a kind of intake manifold and fuel nozzle are installed combination, comprise motor, intersection at engine chamber and intake duct forms a valve storehouse, be fixed with fuel nozzle near on the intake manifold in this burner port valve storehouse, its key is: described fuel nozzle is towards described burner port valve storehouse, and the center line in the elongation line of the center line of fuel nozzle and described burner port valve storehouse intersects, and the engine-mounted valve in center line Tongan City in this valve storehouse and the longitudinal center line of valve stem are point-blank;
Fuel nozzle is towards burner port valve storehouse, avoid oil-gas jetting to the intake manifold inwall, when burner port is opened, fuel nozzle directly sprays to the firing chamber, negative pressure in the firing chamber sucks the firing chamber with oil gas to greatest extent simultaneously, avoid oil gas on gas manifold inwall and valve stem, to liquefy, prevented the generation of the wet wall phenomenon of intake manifold.
Be connected with magnetogenerator on the described engine output shaft, on this magnetogenerator electromagnetic sensor be installed, the output terminal of this electromagnetic sensor is connected on the crankshaft information input end of ECU, and the oil spout control end of ECU connects described fuel nozzle;
By the magnetogenerator corner, obtain the engine crankshaft job information, when ECU determines motor when being in suction stroke, burner port is opened, and this moment, fuel nozzle sprayed oil gas.Guaranteed that fuel oil energy fully burns.
Described ECU is provided with:
Be used to obtain the device of magnetogenerator corner information;
Be used to judge whether motor is in the device of suction stroke;
When if motor is in other stroke, then return the described device that is used to obtain the magnetogenerator corner information;
When if motor is in suction stroke;
Be used to control the device that fuel nozzle sprays oil gas.
Different air valve structures, fuel nozzle center line guarantee that towards different positions oil gas can maximum flow inject directly into the firing chamber.
Movable valve is housed in described engine chamber implication door storehouse, and this valve is arranged on the valve stem bottom, and this valve stem stretches out outside the valve storehouse; When burner port was stated in the valve-closing residence, the center line elongation line of described fuel nozzle passed the center of described valve and valve stem junction plane.
Movable valve is housed in described engine chamber implication door storehouse, and this valve is arranged on the valve stem bottom, and when burner port was stated in the valve-closing residence, the center line of described fuel nozzle passed the center of described valve.
Beneficial effect: the utility model provides a kind of intake manifold and fuel nozzle that combination is installed, when the engine chamber mouth is opened, the oil gas that can guarantee the fuel nozzle ejection can both directly be admitted to engine chamber, avoid the generation of the wet wall phenomenon of intake manifold, guaranteed that fuel oil energy fully burns.
