Abstract

The utility model relates to an environment-friendly fuel economizer used for a fuel-fired electrical fuel injection (EFI) engine, which comprises an inlet gas-purifying pump, a solenoid valve for controlling the gas inflow and an electronic control chip for controlling the on-off of the solenoid valve. The gas inlet end of the purifying pump is connected with an air filter and communicates with the air, and the gas outlet end thereof is connected with the front end of the intake manifold of the engine. The electronic control chip collects a signal from the electric throttle sensor of the vehicle. The on-off of the valve core of the solenoid valve is controlled by the throttle. The fuel economizer is used in the EFI engine of the vehicle to provide the effects of safety, environmental-protection, fuel-saving and boosting. Without changing the original structure of the vehicle, the fuel economizer ensures the uniformity of the rotation speed of the engine, reduces the noise, keeps the idle speed stable and increases the power by more than 20%. Additionally, the fuel economizer has the advantages of light weight of the accelerating pedal, short gear-shifting interval, long life cycle of the engine oil, complete elimination of the carbon deposit inside the cylinder and efficient protection of the cylinder. Under the working condition, the engine power is retained against the remarkable drop, the harmful gas content of the exhaust of the engine is reduced by more than 50-80%, and the overall fuel-economizing rate in the actual use is more than 10%.

Description

Fuel oil electronic fuel injection engine environment-friendly oil economizer

Technical field

The utility model relates to the gasoline-saving device of automobile, is specifically related to quantitatively to regulate the fuel oil electronic fuel injection engine energy-increasing environment-friendly fuel economizer that the fuel mixture body is given input.

Background technique

The air inlet system and exhaust system of fuel engine are made up of intake manifold, gas exhaust manifold, outlet pipe and silencing apparatus etc., its function is that inflammable mixture or fresh air are assigned in each cylinder equably, and compile waste gas behind each cylinder combustion, discharge from exhaust silencer.In the prior art, the air demand of the intake manifold of air inlet system and exhaust system is often not enough, and it is unsatisfactory that inflammable mixture is mixed, and it is insufficient to burn, and has not only caused energy waste but also befouling environment.Especially the oxygen deficiency in the EFI gasoline engine combustion chamber; it is insufficient to cause burning; weakened the power of motor, formed the engine interior carbon distribution, harmful gases such as carbon monoxide, hydrocarbon and oxynitrides bring certain influence to the working life and the environmental protection of motor.For this reason, the gasoline-saving device of various structures arises at the historic moment, but existing gasoline-saving device is only applicable to the motor with carburetor structure, as China Patent No. is 03268017.1 disclosed " a kind of oil-fired vehicle gasoline-saving device ", with China Patent No. be 03279515.7 disclosed " self-controlled type automobile fuel-saving device " or the like, it is mainly used in the latter and overcomes vehicle when deceleration is slided, because of time of engine low speed is still continuing the wasting problem of idling fuel feeding; And China Patent No. is 200620022243.6 " the automatically controlled energization fuel economizer of petrol engine ", because suction tude directly links to each other with engine intake manifold, this fuel economizer and motor produce resonance, have the big shortcoming that directly influences the working life of this fuel economizer of noise.

The model utility content

At the prior art above shortcomings, the purpose of this utility model provides a kind ofly makes second compensation to the EFI petrol engine, and can quantitatively regulate the fuel oil electronic fuel injection engine environment-friendly oil economizer that the fuel mixture body is given input.

The purpose of this utility model is achieved in that fuel oil electronic fuel injection engine environment-friendly oil economizer, it is characterized in that by the air inlet self-fractionating pump, the solenoid valve of control air inflow and the electronic control chip of control electromagnetic valve switch constitute, the inlet end of self-fractionating pump connects air-strainer and communicates with air, and the outlet side connects the front end of engine intake manifold; The electronic control chip is gathered signal from the motorcar electric throttle sensor, by the switching of Throttle Opening Control valve core of the electromagnetic valve.

Compared to existing technology, the utlity model has following advantage: be used on the EFI petrol engine of automobile, have effects such as safety, environmental protection, fuel-economizing, energization; do not need to change the structure of former car; make and start rotating speed even, noise reduces, and idling is steady; power improves more than 20%; accelerator pedal obviously lightens (throttle fits well very much), and shift intervals shortens, and prolongs the machine oil life cycle; thoroughly remove the carbon distribution that is deposited in the cylinder body, can protect cylinder.During working state, engine power does not have obvious decline, and engine exhaust emission harmful gas content reduces more than the 50-80%, and the comprehensive fuel saving ratio of actual use is more than 10%.

Embodiment

Fuel oil electronic fuel injection engine environment-friendly oil economizer, by self-fractionating pump 1, the solenoid valve 2 of control air inflow, the electronic control chip 3 of control electromagnetic valve switch constitutes, the inlet end of self-fractionating pump 1 connects air-strainer 5 and communicates with air, and the outlet side connects the front end of engine intake manifold; Electronic control chip 3 is gathered signal from the motorcar electric throttle sensor, by the spool switching of Throttle Opening Control solenoid valve.Owing to adopt the spool of the accurate control electromagnetic valve of throttle to open and close, automatically regulate the air inlet amount that purifies and to reach the optimum air combustion ratio that is directly proportional with engine speed, it is light and handy, sensitive to play the throttle reaction, ascending speed is accelerated, increase the power of motor, reduce the effect of exhaust emissions, the air inlet of self-fractionating pump is used to solve the problem that EFI petrol engine oil consumption increase, function reduction and tail gas increase.Steam outlet pipe of the present utility model links to each other with the engine intake manifold front end, can avoid this fuel economizer and motor to produce resonance, can not produce noise and the working life that influences this fuel economizer.

In addition, also be provided with manually operated valve 4, can be convenient for changing or cancel this fuel oil electronic fuel injection engine environment-friendly oil economizer in the outlet side of self-fractionating pump 1.
