Description
Technical field
The utility model relates to a kind of motorcycle engine, relates in particular to the motorcycle engine air inlet system.
Background technique
At present, general motorcycle engine air inlet system is made of parts such as motor, engine air inlet tube, Carburetor, empty filter steam outlet pipe, empty filter and empty filter suction tude.The import of its hollow filter suction tude and empty filter is joined, and the outlet of empty filter is connected with the suction port of Carburetor by empty filter steam outlet pipe, and the outlet of Carburetor communicates with engine chamber by engine air inlet tube.Outside fresh air is entered in the sky filter by empty filter suction tude, after cleaner cartridge cleaner filters out dust and other impurity, entering Carburetor by empty filter steam outlet pipe again mixes with gasoline, mixed gas enters the acting of engine combustion Indoor Combustion by engine air inlet tube, for motorcycle provides power.
The intake efficiency of motor directly determines the performance of motor, and intake efficiency is high more, and the performance of motor is good more.And the intake efficiency of motor is relevant with the circulation coefficient of gas, and the circulation coefficient is inversely proportional to the ratio of duct length and pipe diameter, under the constant prerequisite of pipe diameter, duct length is more little, the circulation coefficient is big more, and the flow of gas is also big more, and the intake efficiency of motor is just high.Therefore, empty filter is arranged in the next door of Carburetor, the length that shortens empty filter steam outlet pipe as far as possible is to improve the ideal scheme of engine charge efficient.But in the practical layout of Finished Motorcycle of motorcycle, particularly on beach buggy, because the space on Carburetor next door is less, can't hold the sky filter installs, must on car body, other position that is fit to be installed by empty filter, cause the empty filter steam outlet pipe between sky filter and the Carburetor to extend thus, the circulation coefficient of gas in empty filter steam outlet pipe diminishes like this, the intake efficiency of motor reduces, the ratio that enters indoor oil of engine combustion and gas is excessive, make mixture combustion insufficient, and then reduced the power and the moment of torsion of motor that the performance of motor is difficult to ensure.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of motorcycle engine air inlet system, with the intake efficiency of effective raising motor, ensures engine performance.
The technical solution of the utility model is as follows: a kind of motorcycle engine air inlet system, the import of empty filter suction tude and empty filter is joined, the outlet of empty filter is connected with the suction port of Carburetor by empty filter steam outlet pipe, the outlet of Carburetor communicates with the firing chamber of motor by engine air inlet tube, its key is: be fixed with an airtight air supply tank on described empty filter steam outlet pipe, the inner chamber of this air supply tank communicates with the inner chamber of empty filter steam outlet pipe by suction port and air outlet, in the suction port of air supply tank, be equipped with and make gas, be equipped with in the air outlet of air supply tank and can make gas from the gas outlet valve of air supply tank to empty filter steam outlet pipe one-way flow from the suction valve of empty filter steam outlet pipe to the air supply tank one-way flow.
The utility model is set up air supply tank on empty filter steam outlet pipe, can to improve the intake efficiency of motor, ensure engine performance by the firing chamber tonifying Qi of air supply tank to motor under the not enough situation of air input of engine by air.When engine valve was not opened, the air pressure in the air supply tank, the air pressure in the empty filter steam outlet pipe and extraneous atmospheric pressure equated that the suction valve and the gas outlet valve of air supply tank are in closed condition; When motor is opened valve, because gas pressure is low in the firing chamber, air in so empty filter steam outlet pipe enters Carburetor to be mixed with gasoline, the diameter of section of engine air inlet tube is bigger than the diameter of section of empty filter steam outlet pipe, make the induction air flow ratio of air strengthen, and the gas pressure in the empty filter steam outlet pipe reduces, air pressure balance between empty filter steam outlet pipe and the air supply tank is broken, this moment, the gas outlet valve of air supply tank was opened, air in the air supply tank is mended in the sky filter steam outlet pipe, make the air inflow of motor increase, correspondingly improved the intake efficiency of motor; After engine charge is finished, valve-closing, this moment, external atmospheric pressure was greater than the gas pressure in the empty filter steam outlet pipe, air can constantly enter in the sky filter steam outlet pipe by empty filter suction tude and empty filter, when the air pressure in the empty filter steam outlet pipe during greater than the air pressure in the air supply tank, the gas outlet valve of air supply tank cuts out, and the inlet open of air supply tank, qi of chong channel ascending adversely in air supply tank, air pressure in external atmospheric pressure, empty filter steam outlet pipe and the air pressure in the air supply tank equate, the suction valve of air supply tank cuts out, and waits for the next air inlet circulation beginning of motor.
Above-mentioned air supply tank is positioned at the next door of carburetor air mouth, and fixes by heat seal and empty filter steam outlet pipe, and the distance between air supply tank air outlet and the Carburetor is less than the distance between air supply tank suction port and the Carburetor.Fix by heat seal between air supply tank and the empty filter steam outlet pipe, not only technology is simple, and connects reliably, can prevent effectively that air supply tank from coming off.The air outlet of air supply tank is near the suction port of Carburetor, and the air of mending sky filter steam outlet pipe from air supply tank can in time enter the Carburetor like this, has further guaranteed the air inlet effect.
Above-mentioned air supply tank is a cuboid, to help air ventilation, prevents that eddy current from producing.
Beneficial effect: the utility model can replenish air to the firing chamber of motor by air supply tank, to improve the intake efficiency of motor, the proportions of ingredients that guarantees indoor oil of engine combustion and gas meets the demands all the time, mixed gas can fully burn, improve the power and the moment of torsion of motor thus, ensured the performance of motor.
