Abstract
The invention discloses a manual-control driving and sensing precision fine-tuning intelligent oil feeder comprising an oil feeder body, an oil-inlet oil needle lift mechanism and a throttle valve opening mechanism, wherein the oil-inlet oil needle lift mechanism is arranged on the oil feeder body and comprises an oil needle lift position sensor; and the throttle valve opening mechanism comprises a throttle valve opening position sensor and an ECU (Electronic Control Unit). The invention combines the oil-inlet oil needle lift mechanism with the throttle valve opening mechanism; the ECU controls throttle valve opening according to a lift position signal of the oil-inlet oil needle lift mechanism and other motor vehicle driving parameter signals and verifies and detects whether the throttle valve opening is a needed opening or not by using a position sensor signal of the throttle valve opening mechanism so as to prevent signal disorder, step losing and uncontrollability, therefore the optimal matching and the control of the throttle valve opening and oil needle lift are achieved; thus a flammable mixed gas needed by theoretical air-fuel ratio is achieved, and then the optimal matching and the control of the engine power target (load and rotating speed), the oil needle lift, the throttle valve opening and the gear are realized.
Description
Technical field
The present invention relates to a kind of engine fuel system parts, particularly a kind of manual transmission, sensing fine adjustment intelligence 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 when engine operation are one of most important indexs of motor, have determined power performance, the fuel-economy performance of vehicle, and whether discharge meets environmental requirement.
Engine combustion ideal air-fuel ratio: the perfect combustion of 1g gasoline needs 14.7g air in theory.The different air fuel ratios of operating mode different as:
1, idling: A/F=10～12:1;
2, while startup because the impact of the various factorss such as combustion performance is bad needs the dense mixed gas of spy: A/F=7～8:1;
3, when low speed be stability and the transitional denseer mixed gas (A/F=12～14:1) that needs that keeps good;
4, for improving Economy, abundant burning needs economic mixture gas area when middling speed: A/F=15～17:1;
5, be to improve power to need denseer mixed gas A/F=13～15:1 when high speed.
Current electronic controlled carburetor both domestic and external mainly adopts 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 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 the switching time of valve by dutycycle, the time that the large valve of dutycycle is opened is long, air compensation is just many, otherwise few, therefore by regulating dutycycle just can regulate air compensation.It controls thinking is by regulating air compensation to carry out indirect regulation air fuel ratio;
The second air compensation hole type carburetor, its making-up air device is drawn air supply passage to Carburetor from air-strainer below, centre is provided with one group of tonifying Qi metering-orifice, this making-up air device utilizes the pressure difference that Carburetor throttling produces, by tonifying Qi metering-orifice, air inlet is carried out to tonifying Qi, and the switch of metering-orifice is by Single-chip Controlling.Making-up air device contains 3 metering-orifices, utilize metering-orifice various combination change air compensation number, 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 air fuel ratio in certain limit adjustment, have reduced to a certain extent discharge and oil consumption, but still exist a lot of defects:
1, owing to not possessing spindle lift range sensor and engine load sensor, can not automatically detect the fuel delivery variation that 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 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, be all directly by operation speed-regulating handle or gas pedal control air inflow and oil inlet quantity substantially.More impossible transition and the process control that realizes air fuel ratio ideal point and ideal point;
E, because closure is fixedly connected with spindle, oil inlet quantity and air inflow synchronously change, and can not regulate in real time different fuel delivery and air demands form different air fuel ratios according to motor and road condition;
Above-mentioned reason can cause air fuel ratio and motor operation conditions incompatible.Do not reach state's III, more cannot reach the requirement of the higher energy-saving and emission-reduction such as state's IV.
Use at present maximum various Carburetors of existing Motor Vehicle.Adopt manual control carburetor needle valve aperture and throttle opening, in general motorcycle carburetor, spindle and closure and throttle control mechanism directly connect synchronizing moving and reach the object of adjustment engine operating state.And the subjectivity of driver is depended in the operation of manual control (manual or foot-propelled) completely, owing to not possessing automatic detection, correction and eliminating driver's error in operation, cannot 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 turned round motor under unsteady state operating mode, must cause engine power and running resistance to be difficult to mate, and causes motor fluctuation of service; Simultaneously; Motor Vehicle by driver in the situation that not knowing running resistance; the speed change gear that only rule of thumb operation is controlled; usually can be in the time of startup, upward slope and heavy load, because running resistance increases; force engine speed to decline in the work of inefficient district; 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 discharge.
Therefore, need to improve engine oil device system, regulate the size of controlling fuel delivery for the train signal transmitting, meet 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 efficiently operation, capable of saving fuel oil reduce discharge when meeting the target power of the required control of motor.
