Description
Technical field
The present invention relates to the control system of the auxiliary device of vehicle motor, particularly relate to a kind of control system of remote control valve.
Background technique
Motor is widely used in all trades and professions, in Modern Traffic means of transportation such as vehicle, steamer etc., generally adopts the piston internal-combustion engine using fuel oil as power source.This employing fuel oil as the motor of power source on the one hand because oil inflame is insufficient, make in the gas of discharging containing a large amount of harmful matters and befouling environment, fuel oil on the other hand because using refines from oil and obtains, and the day by day in short supply of petroleum resources makes the development of fuel engine and utilization be subject to increasing restriction.Therefore new, clean, free of contamination alternative energy source is developed, or reduce fuel consume as much as possible, reduction discharge becomes urgent problem in development of engine, just in time meet this requirement using pressurized air as the air-powered motor of power source.
The claimant of the application discloses a kind of air power engine assembly that can be used for transport facility, the turbo dynamo that this motor comprises gas holder, air distributor, engine body, clutch, clutch, automatic transmission, differential mechanism and is placed in exhaust chamber in its patent documentation CN101413403 A (its international application of the same clan is WO2010051668 A1).This motor utilizes compressed air to do work and does not use any fuel, so there is no toxic emission, achieves " zero-emission ", and reuses waste gas and generate electricity, and saves the energy, reduces cost.But this motor is based on traditional four stroke engine, and bent axle often rotates 720 °, piston acting once.And can promote piston acting when entering in cylinder as the pressurized air of power source, then discharge, namely the stroke of compressed air engine is actual is air inlet-expansion stroke and discharge stroke.Obviously, this four-stroke compressed air engine disclosed in patent documentation CN101413403 A wastes effective expansion stroke greatly, limits the efficiency of motor.And the tail gas of this motor fails to recycle well, need enough large gas holder deposit pressurized air could work the sufficiently long time.
Based on the problem existing for patent application CN101413403 A, the claimant of the application discloses a kind of compressed air engine assembly with tail gas recycling loop in China's application of 201110331809.9, and this motor comprises cylinder, cylinder cap system, air inlet pipeline, gas exhaust piping, piston, connecting rod, bent axle, exhaust cam shaft, admission cam shaft, front gear box system and rear gear box.This motor utilizes compressed air to do work and does not use any fuel, so there is no toxic emission, achieves " zero-emission ", and recycles waste gas and do work, and saves the energy, reduces cost.But this motor is In-line multi-cylinder engine, only a controller valve is installed in each controller valve port in controller, when engine total length is certain, limits cylinder cylinder number, thus limit the gross output of motor.Obviously, this in-line multi-cylinder air-powered motor gross output disclosed in 201110331809.9 # applications is not high, and the configuration of motor is still worth exploring.
Based on the problem of application # existing for 201110331809.9, the claimant of the application discloses a kind of V-type multi-cylinder aerodynamic engine in China's application of 201210063546.2, comprising: multicylinder engine body, cylinders power distributor, power equipment, controller system, air inlet control series flow control valve, compression gas tank group, constant-pressure tank, electronic control unit ECU, pressurized air heating equipment and selectable second for air circuit.Be intended to the output power problem and the circulation of tail gas Utilizing question that solve air-powered motor, thus realize Novel compressed air motor that is economic, efficient, zero-emission.But this motor is not high to compressed-air actuated utilization, larger to compressed-air actuated demand during piston cylinder acting.
Found out by above various air-powered motors, existing air-powered motor is identical with other motor in prior art, all need storage battery as power source, storage battery is first relied on to provide power by engine start, when storage battery does not have electricity, motor cannot start like this, and vehicle cannot travel.
