Description

Fuel saving device of double cavity type carburetter

The utility model relates to the fuel economizer that a kind of twin barrel carburetor petrol engine uses, and it is installed in automotive gasoline engine intake manifold top, the Carburetor below.

The twin barrel carburetor petrol engine that uses generally is not provided with gasoline-saving device at present, the oil consumption height, and seriously polluted, the vacuum type chock plate of paying the chamber is idle through the evidence that runs up, and does not possess the fuel feeding effect so pay chamber fuel feeding metering-orifice; Oil in the mixed gas of main chamber, the gas proportions of ingredients is higher, and the Carburetor atomizing is poor, thereby this petrol engine oil consumption height.

The purpose of this utility model is to overcome the deficiency in the background technique and provides a kind of fuel-economizing, discharge amount of exhaust gas little, improves the twin barrel carburetor petrol engine fuel economizer of engine power.

The purpose of this utility model is achieved in that it comprises shell, upper end cap, lower end cap, end cap is welded on the shell respectively up and down, upper end cap is provided with the master, pays inlet hole, lower end cap is provided with exhaust port, is communicated with the engine charge hole, is provided with distance piece in housing, the distance piece right side is a main gas tank, the primary inlet port on its top is communicated with cooperation with the carburetor main chamber, and the space bar left side is for paying suction chamber, and pair inlet hole on its top is paid the chamber with Carburetor and is communicated with cooperation; The last plane of fan blade is fixed on the center fixed plate, and the fan blade end is fixed on main gas tank's inwall, constitutes vortex chamber by fan blade, center fixed plate, main gas tank.Between center fixed plate and suction chamber inwall, constitute mixed gas passage.On the center fixed plate of paying air chamber one side, be provided with the quantitative air hole.

The purpose of this utility model can also realize by following technical measures: former carburetor main chamber closure is sleeved in main gas tank's inlet hole, and a pair chamber closure is sleeved on a pair suction chamber and pays in the intake valve.The vacuum chock plate that the Carburetor that will match with this fuel economizer is paid the chamber dwindles or an end is turned up one section, forms vent.The utility model can also install manually operated regulating controller additional, places to pay in the air chamber, and the regulation and control rocking arm is connected with Air strangler spindle, is gone between to operator cabin by the regulation and control rocking arm, opens the semilune exhaust port below chock plate.

Working principle of the present utility model is: overcome the unreasonable of the fuel feeding of twin barrel carburetor and distribution, strengthen the vaporization degree of mixed gas, the design of this fuel economizer is when supplying oil and gas is finished in main chamber, utilizes the intake passage structure of paying the chamber, dwindles air inflow.When main two closures in chamber of paying under different situation of the interlock time difference, main chamber closure is opened earlier, realize elementary enriching, in order to acceleration, when this closure reaches near moderate duty, pay the chamber closure and begin to open, thereby the quantitative air in dispensing master chamber, make mixed gas from dense to rare, be more suitable for the needs of engine speed this moment, thereby realize the fuel-economizing purpose.When the master, pay the chamber mixed gas through the fuel economizer master, pay an inlet hole enter main, pay air chamber, and join, and, prolonged the vortex chamber gasification time through the putting english effect of eddy current effect and fan blade at the vortex chamber of fuel economizer realize the purpose of fuel-economizing well owing to vaporize.

The utility model has following advantage compared to existing technology:

Rational in infrastructure, make full use of the twin barrel carburetor structure and improve, transform conventional air inlet area, remain supply engine reasonably oil, gas matched proportion density, oil-gas ratio is big when just beginning to start, be convenient to starting, during to moderate duty, pay the chamber closure and open, replenish air, and further mix vaporization at vortex chamber, make gasoline combustion abundant, thereby reach fuel-economizing, improve engine operation efficient, discharge amount of exhaust gas is little, through experiment, fuel saving ratio reaches 20-30%, improves engine operation efficient 8-12%.
