Abstract
The utility model discloses a motorcycle engine crankcase gasoline trap comprising a gas-oil dissociation casing and an exhaust nozzle, a flange is arranged on the bottom of the gas-oil dissociation casing connected with the engine cylinder head, is provided with a baffle inside, one side of the baffle is closed connected with the gas-oil dissociation casing wall, and the other side is open. The baffle divides the gas-oil dissociation casing into two parts, one is the gas-oil dissociation space and the other is exhaust space, the gas-oil dissociation space is communicated with the vent port of the engine cylinder head, the vent of the exhaust space is communicated with the exhaust nozzle, the lower limb of the connection of the baffle and the engine cylinder head is closed connected with the engine cylinder head. The utility model makes the unburned gas influxing into the oil drop and returning back to the cylinder, prevents the unburned gas entering aeration pipe and returning back to the firebox through the air cleaner, reduces the carbon distribution produced at the spark plug, doesn't process exhaust pollution, increases the air cleaner useful time.
Description
Technical field the utility model relates to a kind ofly gets rid of the device that gas carries out Oil-gas Separation, particularly a kind of crankshaft box of motorcycle engine deaerator to crankshaft box of motorcycle engine.
The background technique motorcycle engine is when work, piston moves reciprocatingly, unburned gas and combustion gas can be leaked out from the firing chamber by the gap between piston and the cylinder, enter breathing pipe and return the firing chamber and burning once more, therefore can produce carbon distribution at the spark plug position, influence the motor normal combustion through air-strainer, cause exhaust pollution, unburned gas is by Carburetor the time simultaneously, and the Carburetor oilhole that may result in blockage stops up, and makes engine operation undesired; Unburned gas also can pollute air-strainer by air-strainer the time, makes air-strainer not reach the effect of filtering.
The summary of the invention the purpose of this utility model is exactly at the deficiencies in the prior art, provide a kind of prevent unburned gas enter breathing pipe through air-strainer return the firing chamber and once more the burning the crankshaft box of motorcycle engine deaerator.
The technical solution of the utility model is as follows: a kind of crankshaft box of motorcycle engine deaerator is made of Oil-gas Separation lid, exhaust nozzle; The bottom of Oil-gas Separation lid is provided with flange and is connected with engine cylinder head, be provided with baffle plate in it, the airtight connection of inwall of one end and Oil-gas Separation lid, the other end opens wide, and the Oil-gas Separation lid is divided into two spaces, Oil-gas Separation chamber and exhaust chamber, the Oil-gas Separation chamber is connected with the air outlet of engine cylinder head, the relief opening of exhaust chamber and exhaust nozzle conducting, exhaust nozzle is connected with air-strainer, and baffle plate is connected with engine cylinder head is airtight with the lower edge that engine cylinder head joins.
The front portion of described relief opening is provided with the choked flow frame, and enclosing is in the front portion of relief opening, and its upper edge is higher than the upper edge of relief opening.
Described baffle plate is L shaped.
The lower edge that described baffle plate and engine cylinder head join is provided with spill port, through baffle plate.
Described exhaust nozzle covers airtight the connection with Oil-gas Separation, forms buffer cell at the relief opening and the exhaust nozzle conducting position of exhaust chamber.
Described exhaust nozzle buffer cell is provided with 2-8 towards the inwall of relief opening and props up spoiler, be looped around relief opening around.
Crankshaft box of motorcycle engine deaerator of the present utility model, can make the integrated oil droplet of unburned gas return cylinder, prevent that unburned gas from entering breathing pipe and returning the firing chamber through air-strainer, minimizing produces carbon distribution at the spark plug position, do not cause exhaust pollution, prolong the working life of air-strainer.
