Description
Technical field
The present invention relates to a kind of engine fuel system parts, particularly a kind of manual-control wheel-type transmission sensing fine tuning intelligent oil feeder.
Background technique
Motor is the power source of Motor Vehicle, and its operation conditions is directly connected to the rideability of Motor Vehicle, comprises that for the each economic target of Motor Vehicle cost, environmental-protecting performance etc. all have conclusive impact.Appropriate fuel delivery, air demand and air fuel ratio during engine operation are one of most important indexs of motor, have determined power performance, the fuel-economy performance of vehicle, and whether discharging meets environmental requirement.
The engine combustion ideal air-fuel ratio: the perfect combustion of 1g gasoline needs the 14.7g air in theory.The different air fuel ratios of operating mode different as:
1, idling: A/F=10～12: 1;
When 2, starting because the impact of the various factors such as combustion performance is bad needs the dense mixed gas of spy: A/F=7～8: 1;
3, during low speed for keeping good stability and the transitional denseer mixed gas (A/F=12～14: 1) that needs;
4, for improving Economy, abundant burning needs economic mixture gas area during middling speed: A/F=15～17: 1;
5, need denseer mixed gas A/F=13～15: 1 for improving power during high speed.
Present electronic controlled carburetor both domestic and external mainly adopts the bypass air-supplementing method, structurally comprises two kinds of duty ratio valve formula and air compensation cellular types:
The first duty ratio valve formula electronic controlled carburetor, its do-part is the electromagnetism aeration valve, the outlet of aeration valve air inlet termination air-strainer, the outlet of aeration valve outlet termination carburetor throttle is a kind of duty ratio valve of fixed frequency, is determined by dutycycle the switching time of valve, the time that the large valve of dutycycle is opened is long, air compensation is just many, otherwise then few, therefore just can regulate air compensation by regulating dutycycle.Its control thinking is to come the indirect regulation air fuel ratio by regulating air compensation;
The second air compensation hole type carburetor, its making-up air device is drawn air supply passage to Carburetor from the air-strainer below, the centre is provided with one group of tonifying Qi metering-orifice, the pressure difference that this making-up air device utilizes the Carburetor throttling to produce is carried out tonifying Qi by the tonifying Qi metering-orifice to air inlet, and the switch of metering-orifice is by Single-chip Controlling.Making-up air device contains 3 metering-orifices, utilizes the various combination of metering-orifice to change what of air compensation, and 3 metering-orifices have 8 kinds of different compound modes.
Above-mentioned two class electronic controlled carburetors are controlled air fuel ratio by adjusting air inflow quantity, can realize that air fuel ratio in the certain limit adjustment, has reduced discharging and oil consumption to a certain extent, but still exist a lot of defectives:
1, owing to do not possess spindle lift range sensor and engine load sensor, can not automatically detect the fuel delivery variation that the spindle lift variation is brought, can not automatically detect the steam supplying amount that throttle opening brings changes, therefore, ECU (Electrical Control Unit) can not change according to fuel delivery, real-time matching, correction, adjustment air fuel ratio, reach the optimum Match of throttle opening, rotating speed, moment of torsion and engine gears, cause the motor fluctuation of service;
2, the regulation range of air inflow is limited, and the regulation range of air fuel ratio is narrower;
C, instantaneous conditions response capability are poor;
D, all be directly by operation speed-regulating handle or gas pedal control air inflow and oil inlet quantity basically.Transition and the process control of more impossible realization air fuel ratio ideal point and ideal point;
E, because closure is fixedly connected with spindle, and oil inlet quantity and air inflow change synchronously, can not regulate in real time different fuel deliveries according to motor and road condition and form different air fuel ratios with air demand;
Above-mentioned reason can cause air fuel ratio and motor operation conditions incompatible.Do not reach state III, more can't reach the requirement of the higher energy-saving and emission-reduction such as state IV.
Use at present maximum various Carburetors of existing Motor Vehicle.Adopt manual control carburetor needle valve aperture and throttle opening, spindle and closure directly connect the purpose that synchronizing moving reaches the adjustment engine operating state with throttle control mechanism in the general motorcycle carburetor.And the subjectivity of driver is depended in the operation of manual control (manual or foot-propelled) fully, owing to do not possess automatic detection, correction and eliminating driver's error in operation, can't reach the optimum Match of throttle opening, rotating speed, moment of torsion and engine gears; Change when unexpected in the speed of a motor vehicle, the improper meeting of air fuel ratio is under the unsteady state operating mode motor and turns round, and must cause engine power and running resistance to be difficult to coupling, causes the motor fluctuation of service; Simultaneously; Motor Vehicle by the driver in the situation of not knowing running resistance; only rule of thumb operate the speed change gear of control; usually can be when startup, upward slope and heavy load, because the running resistance increase; force engine speed to descend in the work of poor efficiency district; the driver often too much strengthens fuel delivery and " stops working " to prevent motor, but air fuel ratio control is unsatisfactory, has increased oil consumption and discharging.
For overcoming the above problems, in the prior art, be provided for detecting the sensor of spindle aperture at the Carburetor of motor, sensor reaches ECU (Electrical Control Unit) (ECU) with this aperture signal after detecting the spindle aperture, and ECU (Electrical Control Unit) (ECU) is adjusted gear shift operation automatically according to the aperture signal; This structure can not Proper Match oil inlet quantity and air inflow, and actual air inflow and theoretical air inlet curve have larger difference, and to the adverse effect of engine operating state, the impact discharging also reduces engine operation efficient.And the sensor setting of this structure arranges near the spindle plunger in Carburetor, when particularly adopting the Hall element that validity is higher and adaptability is stronger, need to arrange the appurtenances such as magnet steel, can make the complex structure of Carburetor itself, volume increases, and is unsuitable for to arrange and install; And in-engine high temperature can pass to sensor by spindle, affects the precision of sensor detected parameters, even can send full of prunes signal, affects normally sending of next instruction, thereby affects normally travelling of Motor Vehicle.
Therefore, need to improve engine oil device system, the size for the train signal that transmits is regulated the control fuel delivery satisfies when driving required torque and the speed of a motor vehicle, can according to the size adjustment throttle opening of fuel delivery, control good air fuel ratio; The motor-driven vehicle going parameter signal that this aperture signal combination is other, determine gear shift action and gear shift gear, make actual moment of torsion-rotating speed, spindle lift and throttle opening and gear reach optimum Match, motor is worked under the optimum interval of efficiency and optimum speed state, thereby make that motor remains well, stable state and efficient operation, capable of saving fuel oil and reduce discharging when satisfying the target power of the required control of motor; And sensor can not be subjected to the impact of engine high-temperature, accurately gathers the aperture of carburetor needle valve, avoids occurring the phenomenon of signal entanglement, and simultaneously, simplified structure reduces the installation and removal difficulty.
