Description
Technical field
The utility model relates to the motor car engine field, particularly a kind of motor car engine of single use rock gas.
Background technique
Novel, energy-saving and environmental protection are ideas of development of the required drive energy in New Times society's sustainable development, bring into play gas storage advantage (can use 200 years) simultaneously and demand changing over to the social development demand of power utilization urgently, rely on each side energy pressure such as gasoline, diesel oil for further alleviating automobile power, so to need a large amount of on the market be the motor car engine of fuel with the rock gas.And the existing rock gas that is aided with is that the motor car engine of fuel is commonly with the improved hybrid type duel fuel engine of taking into account rock gas of petrol engine, this motor is by being provided with mixer between air-strainer and intake manifold, or between air-strainer and Carburetor, mixer is set, make rock gas and air in mixer, form inflammable mixture, inflammable mixture sucks the engine chamber work by combustion through the intake manifold negative pressure again, because this mainly is at the Fuel Petroleum characteristics design with the improved complete machine of taking into account the duel fuel engine of rock gas of petrol engine, rock gas and air are formed inflammable mixture be difficult in the best chemically correct fuel of realizing rock gas and air under the different operating modes all the time in mixer, therefore cause the air consumption of motor big, power is low, power character decay 1/3, Here it is generally believes with gasoline or rock gas to be the reason of the hybrid type dual-fuel automobile engine power difference of fuel.If diesel engine is improved to the hybrid type duel fuel engine of taking into account rock gas, because the fuel oil that diesel engine is used is a diesel oil, the diesel oil viscosity is big, vapo(u)rability is poor, can not in Carburetor, form inflammable mixture in advance with air, so diesel engine is to adopt the compression ignite mode, promptly when diesel engine intake is got excited, air is inhaled into cylinder, and compressed rapidly, air pressure and temperature raise, and are closing on compression stroke at the end, by oil sprayer diesel oil are directly sprayed into the firing chamber, with the high temperature in the firing chamber, high-pressure air forms the inflammable mixture and the work by combustion of catching fire voluntarily, for guaranteeing to form high temperature in the diesel engine cylinders, high pressure, the firing chamber is not established in the cylinder head bottom surface of diesel engine, reaches 18: 1 to satisfy compression ratio.Because diesel engine is not lighted a fire and is, but oil sprayer is set to the firing chamber oil spout at cylinder head, if being improved to the hybrid type duel fuel engine of taking into account rock gas, diesel engine just needs engine structure is done bigger change, so improve the hybrid type duel fuel engine of taking into account rock gas without diesel engine usually.Even diesel engine is improved to the hybrid type duel fuel engine of taking into account rock gas, be to form in the mixer between air-strainer and intake manifold also because of its inflammable mixture, form inflammable mixture and be difficult in the best chemically correct fuel of realizing rock gas and air under the different operating modes all the time in mixer, its power character is also poorer than the improved duel fuel engine of petrol engine; Again because diesel engine is being compressed just oil spout at the end, make the mixed gas formation time short, thereby cause the mixed gas composition very inhomogeneous everywhere in the firing chamber, be head it off, the intake duct of firing chamber adopts spiral intake duct to combine with strong vortex air intake manifold usually, produces tangential swirl at intake process, makes the air that enters form strong eddy current in the firing chamber, by at a high speed strong eddy current air the diesel oil that sprays into is evenly distributed on the firing chamber, evaporation forms mixed gas.It is the motor of fuel that yet the intake method of the strong eddy current of this high speed but is not suitable for the rock gas, because of the rock gas mixed gas adopts at a high speed strong vortex air intake, causes the mixed gas detonation easily, damages engine component.In view of the foregoing, so be improved to natural gas engine without diesel engine usually.How solving with diesel engine is the power character of basic improved gas-fueled vehicles motor, is the object of people's research for a long time always, especially solves the raising of power character of the motor car engine of single use rock gas, is the difficult point of research always.
