Abstract
The present invention utilizes the air compressor of automobile pneumatic brake system and compressed air distribution control circuit to make compressed air enter to engine exhaust system and exhaust treating mechanism without changing the performance of brake system. Thus, the exhausted harmful gas is further combusted, oxidized and reduced to reduce the environmental pollution caused by the engine exhaust.
Description
The present invention is about utilizing the air compressor of auto brake system, makes the engine exhaust air inlet in vent systems harmful gas wherein be eliminated before going into atmosphere to the vent systems air supply of motor car engine, reduces the pollution of engine exhaust to atmosphere environment.
Existing method to the automobile exhaust system air feed mainly contains 1) use the special-purpose air pump to the engine exhaust system air feed.Shortcoming: use non-automobile general purpose accessory.2) utilize the exhaust pressure difference to suck air automatically.Shortcoming: effect is not as the air feed of air pump.
The present invention mainly reaches following purpose: the air compressor that promptly makes full use of brake system of car, guaranteeing the following in advance of use for brake system gas, vent systems and purification plant air supply thereof to motor car engine, make engine exhaust can in vent systems, obtain continuing oxidation, burning, required oxygen during reduction reduces the harmful gas of motor to airborne release.Another kind of purpose: provide a kind of when engine start, the method for the air compressor off-load that order is subsidiary.
With reference to shown in Figure 1, on the air duct 17 between the breather check valve 14 of air compressor 12 and braking system 15, manifold 1,3 is set, 4.Solenoid valve 5 is set on manifold 1.The outlet of manifold 1 plug into the discharge manifold 11 of vent systems 10 and with between be communicated with.Solenoid valve 8 is set on manifold 4, and the exhaust mouth is plugged on engine system 10 and is communicated with it.Solenoid valve 6 is set, the plug into breather check valve 13 of gas cylinder 16 of air outlet on manifold 3.The air duct 2 of plugging on gas cylinder 16 is provided with solenoid valve 7 on air duct 2.Plug into manifold 1 and being communicated with it of the air outlet of air duct 2.
The action that compressor air distributes control circuit 9 control electromagnetic valve 5,6,7,8 automatically is set.
As above-mentioned formation:
1) when engine start and idling, pressurized air distributes control circuit 9 (hereinafter to be referred as " control circuit 9 ") control electromagnetic valve 5 automatically, manifold 1 is opened in 6 energisings and action in good time, 3 valve, solenoid valve 7,8 cuts out, the pressurized air that the air compressor of this moment produces under atomic exhaust pressure, pressurized air can reduce the startup load of motor simultaneously by the exhaust of manifold 1 input engine exhaust 11 with purifying engine.
2) when automobile normal running, control circuit 9 control electromagnetic valve 5,6,8 are closed solenoid valve 7 energisings and air duct 2 is opened in action in good time.This moment, gas cylinder 16 interior pressurized gass passed through air duct 2, manifold 1.The discharge manifold 11 of input motor continues the exhaust of purifying engine.
3) when automobile normal running, when the pressure of the gas cylinder 15 of braking system surpassed setting value, control circuit 9 control electromagnetic valve 5,6 were opened, and solenoid valve 7,8 cuts out.The pressurized air part of air compressor 12 generations this moment is by manifold supply engine discharge manifold 11, and another part is supplied with gas cylinder 16 by manifold 3.
4) when pressurized air is constantly imported gas cylinder 16, when the air pressure in the gas cylinder 16 surpasses setting value, control circuit 9, control electromagnetic valve 7 outages are closed, solenoid valve 5, manifold 1,3 is opened in 6,8 energisings and action in good time, 4 valve, this moment, pressurized air stopped to import gas cylinder 16, and by manifold 1,4 supply engine vent systems 10.Participate in purifying engine waste gas.
5) when motor is out of service, control circuit.Control electromagnetic valve 5,6,7,8 outages are closed.
