Abstract
The utility model provides a manual air compensator for LPG vehicle. The technical problem needs to be solved is: the mixer and the engine can not be well matched when the prior LPG device applies the Venturi mixer, namely, the heat efficiency is high and the labor is saved when the mixed gas is sparse, but the power is not sufficient and the acceleration is slow. So that the mixing gas has to be thickened to enhance the power in practical, thereby, the air consumption is raised when the vehicle is in even speed. The utility model is characterized in that: an electromagnet valve is arranged on the vacuum air guide duct, the electromagnet valve is controlled by normally open switch; the air outlet is connected with the air inlet pipe of the engine, and the air inlet pipe is connected with the high pressure cavity in the evaporator of the LPG device. Compared with the prior art, the utility model can regulate the density of the mixing gas according to the different working conditions, thus, not only the power of the vehicle is ensured, but also the air is saved. The utility model is applicable for the LPG vehicle.
Description
[technical field]
The utility model relates to the device in LPG automobile (automobile of burning petroleum liquid gas) adjusted combustion gas air inflow.
[background technique]
In today of pay attention to day by day environmental protection, the LPG automobile is widely used in China.Present LPG device when adopting venturi mixer, exists the problem that mixer and motor can not fine couplings, and promptly the inlet gas concentration in the mixer is certain when automobile running, can not automatically adjust along with the various operating modes of automobile.When mixed gas was rare, thermal efficiency height was economized gas, but is short of power, and acceleration is slow, and peak output descends more than 30%.For this reason in practice, have to be dense with mixing controlled atmosphere, though strengthened power like this, caused the air consumption of automobile combustion gas when at the uniform velocity travelling to rise.
[goal of the invention]
The purpose of this utility model is to provide a kind of LPG vehicle manual making-up air device, when automobile needs mixed gas dense, opens the utility model, it replenishes combustion gas for automobile, makes air-fuel mixture enrichment, when automobile at the uniform velocity travels, disconnect the utility model, keep the original economic mixture strength of automobile.
The purpose of this utility model is achieved in that it is made up of solenoid valve, vacuum air pipe and normal open switch, on the vacuum air pipe, solenoid valve is arranged, solenoid valve is controlled by normal open switch, and the air outlet links to each other with engine air inlet tube, and suction port links to each other with LPG device vaporizer hyperbaric chamber.When automobile need quicken or full load when travelling, the driver presses normal open switch, and solenoid valve gets electric opening, and combustion gas through the utility model, enters engine air inlet tube from LPG device vaporizer hyperbaric chamber, has increased mixture strength, thereby has improved automobile power.Otherwise solenoid valve cuts out air pipe, is not the motor tonifying Qi, and at this moment automobile keeps original economic mixture strength, reaches province's gas purpose.
The utility model compared with prior art, it can be according to the different operating modes of automobile, the concentration of regulating mixed gas had both guaranteed the power of automobile, reached the purpose of province's gas again, and easy to operate.
[description of drawings]
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
[embodiment]
It is made up of solenoid valve 1, air volume regulating valve 2, vacuum air pipe 3 and normal open switch K, solenoid valve 1 and air volume regulating valve 2 are arranged on vacuum air pipe 3 successively, solenoid valve is controlled by normal open switch, air outlet 3.1 links to each other with engine air inlet tube, and suction port 3.2 links to each other with LPG device vaporizer hyperbaric chamber.When automobile need quicken or full load when travelling, the driver presses normal open switch, and solenoid valve gets electric opening, and combustion gas through the utility model, enters engine air inlet tube from LPG device vaporizer hyperbaric chamber, has increased mixture strength, thereby has improved automobile power.Otherwise solenoid valve cuts out air pipe, is not the motor tonifying Qi, and automobile keeps original economic mixture strength, reaches province's gas purpose.
Air volume regulating valve 2 is to regulate air inflow.
Claims (2)
1, a kind of LPG vehicle manual making-up air device, it is characterized in that: it is made up of solenoid valve, vacuum air pipe and normal open switch, on the vacuum air pipe solenoid valve is arranged, and solenoid valve is controlled by normal open switch, the air outlet links to each other with engine air inlet tube, and suction port links to each other with LPG device vaporizer hyperbaric chamber.
2, according to the described LPG vehicle manual of claim 1 making-up air device, it is characterized in that: on the vacuum air pipe, also have air volume regulating valve.
