Description

The distribution device that is used for two-stroke aerodynamic force V-type eight cylinder engine

Technical field

The utility model relates to engine art, especially a kind of distribution device that is used for two-stroke aerodynamic force V-type eight cylinder engine.

Background technique

Motor is widely used in all trades and professions, and the Modern Traffic means of transportation generally adopts with the piston internal-combustion engine of fuel oil as power source such as automobile, steamer etc.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 greenhouse gases and harmful matter in the feasible gas of discharging and befouling environment; 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, cleaning, free of contamination alternative energy source, perhaps reduce fuel consume as much as possible, reduce discharging and become the problem of needing solution in the motor development badly.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 in practical application, still have many difficulties and challenge.

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 demand has just in time been satisfied in the compressed-air power source.
