Abstract
The utility model discloses a fuel economizer for engines, relating to a device used for saving fuel, eliminating smoke and increasing power during the working process of an internal combustion engine. An engine can be affected by various natural conditions during working processes. Load variations frequently occur. Operators can not carry out reactions for changing fuel amounts according to the variations. Thus, the engine usually runs in noneconomic operating state. The utility model solves the problem that a fuel economizer with the advantages of better structure, small size and better fuel saving effect is designed on the foundation of the prior art. The fuel feed controlling mechanism of the fuel economizer for engine is composed of a rotation speed changer, a throttling device and a negative pressure controlling unit. The sections all have fuel saving functions. The comprehensive effect is better then the fuel saving effect of the prior art. The utility model is used for various internal combustion engines, and the fuel saving effect created on a self-propelled vehicle engine is particularly better.
Description
Engine economizer is about saving fuel oil in the explosive motor working procedure, eliminating a kind of device of discharging fume and increasing power.
Energy saving has become the key subjects that current society very pays close attention to.Explosive motor is subjected to various effect of natural conditions in the course of the work, be subjected to the pavement behavior influence as automobile, tractor is subjected to the soil regime influence, load variations appears continually, this variation makes operator can't make the reflection that changes fuel delivery, and therefore, motor often is in the non-economy working state, be not fuel feeding very few be exactly over feeding, produce the not congruent problem of black smoke burning.
The patent No. is that 94201330.1 technology has obtained certain achievement aspect addressing this problem, and the effect of its fuel-economizing is proved by practice.But because its structure is perfect inadequately, not only volume is bigger, and oil-saving effect does not reach desirable level yet
The purpose of this utility model is that to design a kind of volume on the basis of existing technology littler, the economizer of explosive motor that oil-saving effect is better.
This engine economizer is used for various explosive motors especially for the traveling vehicle explosive motor.It reaches the fuel feeding control mechanism that joins with it by flyball formula controlling mechanism and forms.It is characterized in that the fuel feeding control mechanism is made up of speed setting unit, throttle adjustment device and negative pressure adjusting device.This engine economizer drives running by motor.The throttle adjustment device connects with engine vaporizer (petrol engine) or speed regulator (diesel engine), negative pressure adjusting device is installed in petrol engine intake duct a part, negative pressure modulating valve (8) in the negative pressure adjusting device is the solid of rotation of hollow, on the outer surface opening UNICOM intake duct is arranged altogether, diesel engine can be without negative pressure adjusting device.The throttle adjustment device is provided with unsteady regulator (7), in the regulator that floats the flotator spring is housed.Speed setting unit is made up of the Regulation spring (3) of regulating cap (4) and be enclosed within on the speed governing axle (5).
The application of engine economizer makes motor regulate fuel feeding at any time automatically with load variations, makes motor often be in the economic work state, and fuel combustion reduces exhaust Smoke fully simultaneously, reaches the oil-saving smoke eliminating reinforcement effect.
Be described further below in conjunction with accompanying drawing:
When motor caused that because of load variations rotating speed changes, rotating speed adjusting mechanism (2) was passed in the reflection of flyball formula controlling mechanism (1), changed giving tightness and can influencing the sensitivity of throttle adjustment device to engine speed of Regulation spring.The flotator spring in the regulator (7) of floating make when gas pedal (or handle) fixedly the time speed governing axle (5) can move axially.The move left and right of speed governing axle makes QUADRANT (6) swing change the fuel feeding state on the one hand, make fuel feeding more reasonable, make negative pressure modulating valve (8) revolution on the other hand, when the opening on its outer surface and valve seat opening (10) are overlapping, intake duct (11) and atmosphere UNICOM, the cylinder charge coefficient is increased, and AIR Proportional increases, lean out.Above-mentioned two aspects all can more effectively realize fuel-economizing on the prior art basis.
Fig. 1 is the overall schematic of engine economizer.
Fig. 2 is a negative pressure modulating valve schematic representation.
The above course of work has provided the embodiment that engine economizer is used at vehicular engine, and this engine economizer also is highly suitable on the fixedly unit of farming operation.
