Its advantages are use of different fuels including ordinary fuel and high-heat-value alkyl or alcohol substances, gas and powder, short start (especially cold start) time, and less consumption of fuel.
Description
The present invention relates to automobile, particularly a kind of method with plasma excitation automotive engine combustion chamber fuel combustion.
Motor Vehicle such as at present common automobile, motorcycle, except electricity directly driving, their power all derives from motor, wherein the most frequently used is internal-combustion piston engine and gas turbine, they all are to produce heat energy by fuel in the firing chamber internal combustion, and expansion working changes the outside outputting power of mechanical energy into.
Above-mentioned motor must be with spark ignitor or with special fuel and the Air mixing gas as gasoline, diesel oil, rock gas etc. of high pressure compression ignite in the firing chamber when outside outputting power.It not only has certain requirement to the evaporation of special fuel, atomizing and with Air mixing, and, therefore exist the slow and unburnt shortcoming of starting, especially cold starting inevitably to very high cooperation requirement being arranged with spark ignitor or with time of high pressure compression ignite.Partial combustion had both caused the interior situation that can change this inefficiency of mechanical energy into that fuel is contained, can produce harmful gas again, increased atmospheric pollution.
The purpose of this invention is to provide a kind of new method with plasma excitation automotive engine combustion chamber fuel combustion, it makes the fuel of any rareness and Air mixing body under the excitation of plasma, in automotive engine combustion chamber, fully burn, increased the applicability and the interchangeability of fuel.
Technological scheme of the present invention is as follows: a kind of method with plasma excitation automotive engine combustion chamber fuel combustion, the plasma exciatiaon chamber that electromagnetic energy input is communicated with engine chamber, in the plasma exciatiaon chamber, encouraged plasma arc, the fuel and the Air mixing body that are sprayed in the firing chamber by fuel nozzle are fully burnt.
The present invention not only can use common fuels such as gasoline, diesel oil and rock gas, can also be easily alkanes and alcohols material, gas even the solid powder particle etc. of high combustion value be acted as a fuel, greatly improve the efficient that can change mechanical energy in the fuel into, shortened the time of starting, especially cold starting.The size of the also available plasma excitation energy of the present invention and the output power of how much coming to control easily motor that sprays into firing chamber fuel have reduced fuel consumption, have reduced the generation of harmful gas, have alleviated the pollution to air.
