Abstract

The utility model belongs to an ineffectiveness oil cutting-off device for automobile, which is characterized in that a normally closed relay is cascade connected on the circuit between an electric power fuse and an oil injector, two normally closed switch are cascade connected between the positive and the negative poles of the relay, one of the two switches is arranged on the throttle, and the other one is arranged on the detach. The utility model has the advantages of simple structure, convenient installment, and simple operation, no change of the prior habits of the drivers, no affection to the performance of automobiles, gas saving, and the reducing of the air pollution. With the utility model, automobiles are capable of saving the gas up to 30 percents than the prior arts when running in the city or on regular highways, and the utility model is a more ideal controlling device for automobiles with electric injection engines.

Description

No power efficiency for cars oil-break control gear

Technical field

The utility model relates to automobile fuel feeding control gear, is a kind of electronic fuel injection engine no power efficiency for cars oil-break control gear.

Background technique

At present, the electronic fuel injection engine automobile accounts for 70% of total vehicle, this automobile fuel injection quantity and injection time are mainly controlled by bent axle, CMPS Camshaft Position Sensor and lambda sensor, when depress throttle pedal (is commonly called as throttle, hereinafter to be referred as throttle), stepper motor is pressed the given amount of computer and is opened valve, oxygen amount in the gas handling system increases, the computer control oil sprayer strengthens fuel injection quantity, when the automobile speed-raising is travelled, when unclamping throttle, closed throttle, the oxygen amount descends in the gas handling system, and fuel injection quantity reduces, engine retard.Behind car engine, as long as be not related to key, oil sprayer is in the oil spout state always in a word, just divides idling and acceleration.

Automobile is in the urban district and on the ordinary highway in the running process, often run into the situation that the pine tar door slows down or steps on braking deceleration, at the pine tar door or gently step on engine idle work in the process of braking, the car idling is generally 200-800 rev/min, the rotating speed of motor is generally at 1500～2000 rev/mins during driving, if speed per hour at 60km/ constantly, unclamp throttle or gently step on braking, motor is forced idling under action of inertia, slowly drop in 800 rev/mins the process by 2000 rev/mins, fuel oil has been wasted under the situation of not doing any available power, so the driving oil consumption generally will increase 40-50% in the urban district.

Summary of the invention

The purpose of this utility model provides a kind of no power efficiency for cars oil-break control gear, with solve prior art when unclamping throttle or gently step on braking motor by the scanning frequency mandatory down to the process of idling work, the problem that fuel oil is wasted under the situation of not doing any available power.

The purpose of this utility model is achieved in that this device is to be made of oil sprayer, CPU (computer), main fuse and circuit, on circuit between main fuse and the oil sprayer, be connected in series with normal ON state relay, between relay electrode, be connected in series with two normally closed attitude switches, one is installed in the throttle mechanism, and another is installed on the clutch mechanism.

Switch adopts contact switch or magnetic switch.

Magnetic switch is in housing, intrinsic quiet conducting plate and moving conductive sheet, intrinsic magnet steel on the moving conductive sheet.

This model utility compared with prior art has the following advantages: (1) is simple in structure, and is easy for installation; (2) easy to operate, do not change the driver's operation custom, do not influence automotive performance; (3) save fuel oil, reduce atmospheric pollution, compare, in the urban district or on the ordinary highway, travel with former electronic fuel injection engine automobile, but fuel-economizing about 30%.

Fig. 2 magnetic switch component diagram.

Embodiment

On each cylinder of Fig. 1 intermediate fuel oil oil sprayer (1) one, all accept the control of CPU (computer) (2) simultaneously, circuit (3) and main fuse (4) are identical with prior art, on circuit (3) between main fuse and the oil sprayer, a normally closed attitude relay (5) is connected in series, electric current is powered to oil sprayer by the normally closed point of relay (6), between relay electrode (7) is positive and negative, two normally closed attitude switches (8) are connected in series, a switch is installed near the screw of throttle swing arm by support, and its stroke is 2-5mm; Another switch is installed on the clutch free travel adjusting screw by support, and its stroke is 2-20mm, and relay is by the switch control that is installed on throttle mechanism and the clutch mechanism.Switch (8) adopts contact switch or magnetic switch, and contact switch is to be made of quiet conducting plate and moving conductive sheet, intrinsic contact on the moving conductive sheet, and it is upspring by elasticity servo-actuated conducting plate, outer power and closure.

Magnetic switch among Fig. 2: be intrinsic quiet conducting plate (10) and moving conductive sheet (11) in housing (9), intrinsic permanent magnetic steel (12) on the moving conductive sheet, when iron or magnetic substance near to certain distance the time, by magnet steel the suction of iron or magnetic substance is made switch on, circuit turn-on.

Working principle: when not stepping on clutch or gas pedal, switch (8) is in closed attitude, and relay electrode has, normally closed point disconnects, and oil sprayer does not have electricity and stops oil spout, steps on the gas or clutch pedal when one, switch (8) disconnects, and relay electrode does not have electricity, normally closed some closure, the oil sprayer commencement of fuel injection during red lights such as gearshift or short time, stepped on clutch pedal, switch disconnects, relay is normally closed closed, oil sprayer oil spout, engine idle work.

Claims

1, a kind of no power efficiency for cars oil-break control gear, be to constitute by oil sprayer (1), CPU (2), circuit (3) and main fuse (4), it is characterized in that: on the circuit between main fuse and the oil sprayer (3), be connected in series with normally closed attitude relay (5), be connected in series with two normally closed attitude switches (8) between relay electrode is positive and negative, a switch is installed in the throttle mechanism, and another switch is installed on the clutch mechanism.

2, no power efficiency for cars oil-break control gear according to claim 1 is characterized in that: switch (8) adopts contact switch or magnetic switch.

3, no power efficiency for cars oil-break control gear according to claim 2 is characterized in that: magnetic switch is intrinsic quiet conducting plate (10) and a moving conductive sheet (11) in housing (9), goes up intrinsic magnet steel (12) at moving conductive sheet (11).
