Description

The controller that is used for aerodynamic force V-type multicylinder engine

Technical field

The utility model relates to the device that a kind of motor is used, in particular to a kind of controller that is used for aerodynamic force V-type multicylinder engine.

Background technique

Motor is widely used in all trades and professions, and transport facility generally adopts with the piston internal-combustion engine of fuel oil as power source such as in automobile, the steamer etc. in modern times.This employing fuel oil is insufficient because of oil inflame on the one hand as the motor of power source; Contain a large amount of harmful matters and befouling environment in the feasible gas of discharging; Because of the fuel oil that uses is from oil, to refine to obtain, the in short supply day by day of petroleum resources makes the development of fuel engine and utilization receive increasing restriction on the other hand.Therefore develop new, clean, free of contamination alternative energy source, perhaps reduce fuel consume as much as possible, reduce discharging and become urgent problem in the motor development.For this reason, various countries have experienced the road of complicated and hard exploration, have researched and developed multiple power source, such as substitute fuel, motorized motions, fuel cell and solar cell etc.

The substitute fuel automobile; Like rock gas (CNG, LNG) automobile, alcohols automobile, dimethyl ether automobile etc. exhaust emission and thermal effect are arranged still; Some fuel is also toxic, some fuel combustion control difficulty, thereby still have many difficulties and challenge in actual use.

Non-pollution discharge in the electric automobile during traveling, noise is low, energy conversion efficiency is high; But battery-driven electric vehicle is limited by on-vehicle battery; In the degree that is difficult to for the moment aspect specific power, cycle life, charge-discharge performance, cost and the Security reach practical; Simultaneously, there is serious secondary pollution in battery itself.Hybrid-power electric vehicle has the advantage of cell electric vehicle and internal-combustion engines vehicle, but still has discharging and pollution problem, and because the existence of two cover power plant, it drives and control system becomes unusual complicated, thereby has hindered practical application and development.

Fuel cell is placed high hopes by people, can realize the zero-emission of power output, and energy conversion rate is high, but the manufacture cost of fuel cell is high, and the safe storage of hydrogen, preparation and can all have many problems, and this has just restricted the development and the use of this power source greatly.Solar cell still need reduce the battery volume and improve photoelectric transformation efficiency, thereby specifically is applied on the transport facility and still need makes a breakthrough.

In sum, all there is deficiency in the hybrid power source that above-mentioned various new power source or their constitute, thereby, pressing for a kind of not have pollution, nexhaustible novel energy, this requirement has just in time been satisfied in the compressed-air power source.

Study the Designer Guy Negre for French MDI company of compressed-air power engine the earliest; It has proposed the notion of compressed air engine; Attempt to solve the problem of utilizing of " zero-emission " and the energy capable of circulation; From then on opened the new page of engine research, and released the pure aerodynamic economical family expenses bridge car of first item in 2002.The pressurized air compressor uses high pressure air as power source, and air when compressed air engine is worked, can convert the pressurized air stored pressure into other forms of mechanical energy as medium.About the visible FR2731472A1 of the research of compressed air engine, US6311486B1, US2007010110802A1 etc.

FR2731472A1 discloses a kind of motor that can under supply of fuel and two kinds of patterns of pressurized air supply, work; On expressway, adopt conventional fuel such as gasoline or diesel oil; In low speed particularly urban district and suburbs, pressurized air (or other any on-contaminated pressurized gass) is injected the firing chamber.Though this motor has partly reduced fuel consumption, owing to still adopted fuel oil mode of operation, emission problem still to fail to solve.

For further pollution abatement; US6311486B1 discloses a kind of pure air-powered motor; Such motor has adopted three independently chambers: air-breathing-pressing chamber, expansion exhaust chamber and constant volume firing chamber; And air-breathing-pressing chamber is connected to the constant volume firing chamber through valve, and the constant volume firing chamber is connected to the expansion exhaust chamber through valve.One of problem of this motor is that time of experiencing from air-breathing-pressing chamber to the expansion exhaust chamber of pressurized gas is longer; The power source gas time that obtains the driven plunger acting is longer; Simultaneously; Fail to obtain to use from the pressurized gas that the expansion exhaust chamber is discharged, this has just limited this type efficiency of engine and single aeration continuous working period.

More domestic researchers and unit are also studied compressed air engine; But most concentrating on the feasibility and working principle of compressed-air power engine; Such as (" feasibility studies of compressed-air power automobile " such as Xu Hong; " Chinese mechanical engineering " the 13rd volume the 17th phase 1512-1515 page or leaf, in September, 2002).Though more domestic patent documentations are also studied compressed air engine such as CN1851260A, CN100560946C, CN101705841A; But belong to theoretical research and conceptual design more; All fail to solve compressed-air actuated discharging and (have higher pressure usually; Such as about 30bar) and the control and the allocation problem of high pressure air, the contract commercialization process of air engine of tripping is had got long long way to go.

The application's claimant is to disclose a kind ofly with the two-stroke power engine assembly of pressurized air as power source in the application of China of 201110331831.3 at its application number, 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, does not therefore have toxic emission, realized " zero-emission ", and recycling waste gas generates electricity, and has saved the energy, has reduced cost.But this motor is an In-line multi-cylinder engine, in each the controller valve port in the controller controller valve only is installed, and under the certain situation of motor overall length, has limited cylinder cylinder number, thereby has limited the gross output of motor.Obviously, No. 201110331831.3 the disclosed this two-stroke power engine assembly output power of application is not high, has wasted the volumetric spaces of motor greatly, thereby has limited the prospects for commercial application of motor.

Based on the problems referred to above, the utility model provides a kind of controller that is used for aerodynamic force V-type multicylinder engine, is intended to solve the pressurized air adjusting and the allocation problem of V-type multicylinder engine.
