Description
Technical field
The utility model relates to a kind of internal-combustion engine electronics air compensating system and electric controller thereof, refers to a kind of device that is used for field of internal combustion engine especially.
Background technique
The thermal machine that internal-combustion engine transforms as a kind of hot merit, its performance characteristic, Economy and the feature of environmental protection depend primarily on the matching relationship between its structural design, combustion system and three key elements of cycle fluid, and the effect brought into play in the hot merit conversion process of these three elements.For a long time, people have carried out intensive research at these key elements emphatically aspect the research of internal-combustion engine, obtained a large amount of achievements.Supercharging of internal combustion engine is an important means improving engine cycle working medium.Internal-combustion engine has improved the air pressure that enters cylinder by its pressurization system, and air inlet is more abundant, realizes that internal-combustion engine has higher power per liter and combustion efficiency.
Now, along with the pursuit to power per liter and fuel economy, it is very general that internal-combustion engine is set up pressurization system.Particularly legislations of environmental protection is more and more strict to the restriction of discharge of harmful matter of internal combustion engine, has further promoted the development of boosting internal combustion engine in various countries.
Supercharging of internal combustion engine has power per liter and fuel economy significantly improves, the superiority that noxious emission significantly reduces.But internal-combustion engine has also brought some adverse factors after setting up pressurization system.Acceleration as internal-combustion engine reduces, grate flow channel obstruction and air inlet hysteresis etc.The air inlet of pressurization system of internal combustion engine lags behind and is mainly caused by two aspects: the first air intake duct system volume.Especially for constant pressure charging system, its system volume is much larger than the volume of pulse or non pressurized system; The second supercharger rotor machinery inertial.The existence of rotor inertia will cause the air inlet response lag of internal-combustion engine in the fuel feeding of internal-combustion engine.Power of IC engine is bigger, and this hysteresis quality is just more serious.
The hysteresis quality of air-intake of combustion engine will have a strong impact on the acceleration of internal-combustion engine, a large amount of over-emitting black exhausts when causing its variable working condition, phenomenons such as oil consumption rising and carbon-deposits the cylinder.Can cause the complete machine decreased performance and the reliability of internal-combustion engine to reduce when serious.Research is how when guaranteeing the supercharging of internal combustion engine superiority, remedying or eliminate the air-intake of combustion engine that causes because of supercharging lags behind, the serious phenomenon of over-emitting black exhaust when solving the slow and variable working condition of boosting internal combustion engine booster response, being the practical problem that current field of internal combustion engine is badly in need of solution, also is the aspect of the strict control of various countries' environmental regulation.
Internal-combustion engine is in the extensive use in fields such as industry, agricultural, communications and transportation and military affairs, with and the continuous increase of recoverable amount, anxiety day by day along with the international petroleum resource, becoming increasingly conspicuous of earth ecology environmental protection and urban air pollution problem, the realistic problem that current in addition internal-combustion engine exists at aspects such as discharging, oil consumption, noise and reliabilities, all application and development in the future brought stern challenge to internal-combustion engine for these.To this, key industry developed country has all realized the supercharging remodeling of internal-combustion engine at present, and China works out a plan, and diesel engine will be carried out the supercharging type comprehensively, and petrol engine progressively develops to boosting type.
But the serious problem of internal-combustion engine over-emitting black exhaust during the sudden change load is puzzlement people's a difficult problem always.Various countries are also studied all the time to this, have taked many corresponding measures and way.Conclusion is got up, and currently used main method is:
(1) non pressurizedly changes supercharging.Originally non pressurized type internal-combustion engine becomes the supercharging type by installing pressurization system additional, has improved the inlet air amount of internal-combustion engine.This method can be improved the combustion performance of internal-combustion engine in the high load working zone, but the influence that exists the supercharger rotor machinery inertial that air inlet is lagged behind.
(2) improve the supercharging pressure ratio.By when machine is joined in supercharging, select slightly little one grade of pressurized machine for use, set up exhaust discharge valve at pressurized machine volute place simultaneously, under the condition of the whole working condition property of taking into account internal-combustion engine, can further improve the suction pressure of internal-combustion engine.This method can suitably be improved the air inlet response of internal-combustion engine, but still the influence that exists the supercharger rotor machinery inertial that air inlet is lagged behind.
(3) charge inter cooling.By between supercharger outlet and internal-combustion engine import, installing sky-aerial cold or water-aerial cooler additional, air-intake of combustion engine is cooled off, can effectively improve the air quantity that enters in the cylinder, improve burning, remedy the incomplete combustion and the over-emitting black exhaust phenomenon that produce because of lack of air.
(4) supercharger rotor spray air.This method is to calm the anger to hold at pressurized machine to arrange the solenoid valve nozzle, and when internal-combustion engine sudden change operating mode, this solenoid valve is opened, and high-pressure air blows supercharger rotor through solenoid valve and rotates rapidly, in the hope of the suction pressure of rapid raising internal-combustion engine, eliminates the air inlet retardation phenomenon.Supercharger rotor spray air can start the rotational speed of rotor rapidly, but still can't eliminate the influence of the mechanicalness of rotor to the air inlet hysteresis fully, and also inevitable pressurization system volume is to the influence of air inlet hysteresis.
(5) impulse pressure charging system.The volume of this pressurization system is less, can maximally utilise the degassing function of internal-combustion engine, improves the speed of response of supercharger rotor, but that the use of this system is subjected to the restriction of cylinder of internal-combustion engine number is bigger.For heavy duty, the rotor inertia of its pressurized machine is big, and this system is difficult to fundamentally improve the internal-combustion engine over-emitting black exhaust phenomenon that lags behind and cause because of air inlet.
