Background technique
The present invention mainly describes a kind of method that on ignition internal combustion engine, adopts cold conditions plasma hydrogen transducer, and this ignition internal combustion engine adopts gasoline, ethanol or their mixture to act as a fuel.This class A fuel A has narrower lean-burn boundary, and internal-combustion engine usually adopts premixed mode to form the homogeneous inflammable mixture, and fuel air ratio will approach chemical correct fuel air ratio.It is to be noted that the calculating of fuel in the fuel air ratio only considers the fuel that flashes to gaseous state and mix with even air, unevaporated fuel can't be lighted.Because the burning attribute of above-mentioned fuel causes ignition internal combustion engine to have following problem:
(1) amount that adopts closure control to get into the mixed gas of combustion chambers of internal combustion engines.When the demand torque reduced, closure must partly be closed and reduced the air-fuel mixture amount that gets into the firing chamber.Compare during with WOT, this situation can cause sub load air-intake of combustion engine stroke to have tangible restriction loss.More should be noted that all work under part load condition of most operating time of ignition internal combustion engine.
(2) liquid fuel evaporation heat absorption can reduce the temperature of inlet manifold of IC engine, and intake manifold is the place of fuel and air mixing.Cross the steam output that low MAT can reduce fuel, cause part of fuel to be continuously liquid state.It is more poorer that this situation shows when cold start-up operating mode and high-speed working condition.In order to improve internal-combustion engine cold start-up and stable operating performance, the internal-combustion engine control unit need be controlled and spray into more fuel oil when the temperature of internal-combustion engine is low, is used for the shortage of compensate for fuel steam output.Subsequently, will produce partial combustion.Combustion and partially combusted fuel do not eject through outlet pipe, and these all are pollutants.This situation can reduce the fuel economy of ignition internal combustion engine simultaneously.
(3) rich mixture is used in the high-power and normal operation when obtaining WOT, is used to make full use of the air that gets into the firing chamber.Also can produce partial combustion this moment, makes unburned carbon hydrogen and carbon monoxide emission increase and reduce simultaneously fuel economy.
Address the above problem, will adopt weak mixture fully to burn on the one hand, joint valve in the time of will avoiding changing torque simultaneously.These all need be revised the combustion characteristic of fuel.Hydrogen is compared with gasoline, ethanol and their fuel such as mixture as a kind of natural fuel, and following advantage is arranged: rare limit of (1) inflammable mixture is very rare; (2) very high laminar flame velocity of propagation; (3) do not need evaporation time and vaporization to replace heat.Therefore rich hydrogen internal combustion engine can improve the combustion characteristic of ignition internal combustion engine, and partly solves the problem that gasoline, ethanol and their mixture internal-combustion engines exist.In addition, adopt the internal-combustion engine of weak mixture,, can reduce the discharging of nitrogen oxide significantly owing to reduced FT.Simultaneously, internal-combustion engine can adopt high compression ratio and big throttle opening to improve the efficient of entire internal combustion engine.
Summary of the invention
