Abstract
The invention discloses a control method for efficiently and quickly starting an engine. The engine applies a solenoid-driven inlet valve and a solenoid-driven exhausting valve, and is subjected to positioning and electric current double closed-loop feedback control by an engine electric control unit, so as to achieve the independent, continuously variable and real-time regulation of the opening moment, the closing moment, the lift range and the motion rule of the inlet valve and the exhausting valve of the engine; as in the process that the rotational speed of the engine rises step by step, the inlet valve basically keeps an opening state and stops the oil spraying and the ignition of each cylinder until a set rotational speed is reached, under the same power of a starting motor, the transition time can be obviously shortened; and the energy-saving performance and the environment-friendly performance of the engine can be improved.
Description
Technical field
The technical field of the invention is the motor that motor (reciprocating internal combustion engine), particularly a class have been applied Electromagnetic Drive valve.
Background technique
Engine start problem is paid attention in technical development and the problem to its performance important.Conventional engine drives engine start by starting electrical machinery, and identical when in start-up course, intake and exhaust phase place is with its normal operation, circulating fuel injection quantity and ignition energy generally all have increase.In conventional engine, too low, the mixed gas of temperature forms the reasons such as bad owing to starting, and makes the discharges such as CO, HC serious, and diesel engine also has the situation that can not reliably start under low temperature, generally need have the measures such as electric heating.
Research shows, in urban transportation, when automobile is waited for of short duration parking of situation such as green light at traffic intersection, general engine idling operation, not only will consume certain fuel, but also the noxious emission of generation to environment.
Along with the requirement of automobile energy-saving environmental-protecting performance is improved constantly, motor has also been proposed to the requirement of quick startup.For realizing this requirement, the method for application is mainly at present:
1, starting electrical machinery (or integrated starting electrical machinery and generator ISG) and the storage battery of the larger output power of application to shorten start-up course, are easy to realize especially in a class parallel form or Weak hybrid power electric motor car;
2, by control make motor when shutting down piston movement to special position; during startup, in cylinder, direct injection, igniting provide auxiliary power starting motor; this method is not suitable for intake port injection petrol engine, controls comparatively complexity, will consume extra fuel simultaneously yet.The motor existing procucts of Japan mazda motor corporation application the method come out.
In addition, the Chinese invention patent of U.S. Ford motor corporation application " starts the motor with electromechanical valve " and (200510055172.X) proposes control engine valve timing fast, to start fast the system and method for the internal-combustion engine with electromechanical valve.Described method comprises: by a plurality of engine starts position: identification have enough move downward piston cylinder to produce motor output; And air inlet and the exhaust valve timing of at least one power-actuated valve are set, make described cylinder in intake stroke.Starting time when controller electric door reduces engine start.Described method control intake valve and exhaust valve are without complete clearly the cycle of engine of four-journey between the starting period.
Summary of the invention
The object of the present invention is to provide a kind of engine high-efficiency quick start method of applying Electromagnetic Drive valve, thereby reduce fuel consume and the noxious emission of start operating performance.
The technical solution that realizes the object of the invention is: the controlling method that a kind of engine high-efficiency starts fast; engine application Electromagnetic Drive intake valve and Electromagnetic Drive exhaust valve; and by engine electric-controlled unit, it is carried out to position, current double closed-loop feedback control; realize the opening and closing of motor inlet and outlet door constantly, lift and the characteristics of motion thereof independently, adjusting continuous variable, real-time; when motor is when outage state need to start, its efficient controlling method starting fast comprises the following steps:
Compared with prior art, its remarkable advantage is in the present invention: 1), because engine speed is progressively in elevation process, intake valve is held open state substantially, and under same starting electrical machinery power, can obviously shorten transient time; 2) start-up course early stage, when engine speed is not during higher than a certain setting value, not oil spout and igniting, reduced fuel consume and the noxious emission amount of start-up course; 3) suction valve is held open in the time of can reducing start operating performance leakage and the radiation loss producing in compression and inflation process, outlet valve keeps closing can make air temperature in the process of repeated multiple times inflow and outflow cylinder have rising to a certain degree, is conducive to engine start and catches fire.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the engine control system sketch of application Electromagnetic Drive valve
Fig. 2 is the engine structure schematic diagram of application Electromagnetic Drive valve
The implication of number in the figure representative is: 1 Electromagnetic Drive intake valve, 2 Electromagnetic Drive exhaust valves, 3 spark plugs/oil sprayer, 4 connecting rods, 5 starting electrical machinerys.
Embodiment
In conjunction with Fig. 1, Fig. 2; the controlling method that a kind of engine high-efficiency starts fast; engine application Electromagnetic Drive intake valve and Electromagnetic Drive exhaust valve; and by engine electric-controlled unit, it is carried out to position, current double closed-loop feedback control; realize the opening and closing of motor inlet and outlet door constantly, lift and the characteristics of motion thereof independently, adjusting continuous variable, real-time; when motor is when outage state need to start, its efficient controlling method starting fast comprises the following steps:
The setting value of above-mentioned engine speed is a little less than engine idle rotating speed, relevant with factors such as engine type, ambient temperatures, finally should determine by test, to guarantee that oil spout ignition energy catches fire first.
Motor, when quitting work, stops each cylinder working successively by firing order, rather than cuts off each cylinder oil spout and igniting simultaneously.Be mainly to guarantee when next start-up course starts, in each cylinder of motor, all without more waste gas, exist, affect start-up course air inflow.
The present invention is directed to the motor (intake port injection petrol engine, Gasoline Direct Injection Engines or diesel engine) of having applied Electromagnetic Drive valve, do not increasing starting electrical machinery and storage battery output power and do not increasing under the condition of preheating measure, by the regulating and controlling of Electromagnetic Drive valve, realize fast and starting, and significantly reduce fuel consume and the noxious emission of start operating performance.
The fuel of motor is the liquid fuels such as gasoline, diesel oil, or is the gaseous fuels such as compressed natural gas, hydrogen.
