Abstract
A kind of I. C engine fuel auto-supply and saving device is that the negative pressure that suction tude produces during with internal combustion engine is a power, causes that according to rotation speed change intake pipe negative pressure changes principle and implements auto-supply, and fuel feeding is accurate, sufficient combustion, and bad the expense, but fuel-economizing is more than 10%; This device is by the closure controlling component, and speed-regulating part and speed governing positioning element three parts are formed, and are simple in structure, and weight 3-5 kilogram is easy to install, is suitable for four cylinder four-stroke and above internal-combustion engine and uses particularly automobile improvement.
Description
The present invention relates to a kind of I. C engine fuel auto-supply and saving device, is the ideal tools of four cylinder four-stroke and the fuel-economizing of above internal-combustion engine auto-supply, is particularly suitable for the fuel-economizing of automobile auto-supply and transforms.
At present, the automobile fuel feeding all is to step on the gas by the driver, takes a lot of trouble excessive fuel consumption.No. 06/937.295 patent disclosure of the U.S. a kind of " autocontrol oil-saving device for internal combustion engine ", it is by load sensor, throttle converter two parts constitute.A guide rail wing that produces centrifugal force is arranged in the load sensor, be equipped with on the wing and fly the piece group, control the slide block relative movement by centrifugal force pulling automatic control slide block and people, after playing motor magnet, automatic control slide block and people are controlled slide block and are inhaled together, the automatic control slide block drives the people and controls slide block movement, because the people is controlled slide block and linked to each other with the air throttle of car pull bar, has therefore realized with the speed of a motor vehicle variation internal-combustion engine being carried out auto-supply.The maximum shortcoming of this device is: (1) load sensor power taking and induction speed of a motor vehicle difficulty are big, power taking on automobile kilometer master, the driven gear, and moment is very little, if power taking influences this dynamic balancing from the transmission shaft, influences its working life; (2) be subjected to the power taking position limit, be not easy to install; (3) heavy about 30 kilograms.
The purpose of this invention is to provide a kind of simple in structurely, easy to install, volume is little, lightweight I. C engine fuel auto-supply and saving device.
The object of the present invention is achieved like this: the negative pressure that produces 6666-85326Pa when utilizing internal combustion engine in its suction tude is power, according to the variation of negative pressure internal-combustion engine is implemented auto-supply.
This device is made up of closure controlling component, speed-regulating part and speed governing positioning element three parts.The closure controlling component is formed the negative pressure pneumatic mechanism by control cylinder, piston, seal ring, controlling rod, cylinder cap, at the controlling rod the other end, presets spring pagoda of bowls, control spring, spring seat and just is fixed on the end and touches mutually with the closure connecting rod.Piston under the effect of negative pressure and spring, to-and-fro motion in cylinder.The negative pressure pneumatic mechanism of speed-regulating part is identical with the negative pressure pneumatic mechanism structure of the negative pressure pneumatic mechanism of controlling component and controlling component, shape is similar, different is that the pull bar the other end and shift fork flexibly connect, greater than shift fork 1/2 place one support is being arranged, shift fork can be swung around support level, and the shift fork the other end and spring pagoda of bowls flexibly connect.Under suction function, piston passes through pull bar, shift fork, compressive force of control spring is given in the spring pagoda of bowls, to break the state of equilibrium that control cylinder piston and control spring occur, thereby realize changing to the internal-combustion engine auto-supply with the speed of a motor vehicle, the speed governing positioning element is to be provided with the speed governing sliding sleeve in spring pagoda of bowls outside, its outer surface has locating slot and studding bolt, the heart had circular hole at the bottom of speed governing sliding sleeve outside had one, the location cylinder in positioning hole and studding bolt track hole is arranged at top, the closure connecting rod just is preset in the location cylinder, normal expense is fixed on the positioning hole place of location cylinder, the pin head of normally closed pin matches with normal expense, the pin handle of normally closed pin and shift fork flexibly connect, with the shift fork swing normal expense pin of control or open.When the speed governing sliding sleeve when location cylinder bottom is adjusted, the control spring pressurized increases, fuel feeding increases, the speed of a motor vehicle improves, when the speed governing sliding sleeve when the location cylinder oral area is adjusted, the control spring pressurized reduces, fuel feeding reduces, speed of a motor vehicle reduction.
In order to ensure high speed automatic control and auto idle speed, between spring seat bottom surface and the closure connecting rod end face, the gap of 0.5-2mm is arranged when static state.
Under static state, the tip to face distance location cylinder inner bottom surface of closure connecting rod has the gap of 20mm at least.
The speed regulation cylinder cross-section area is greater than the control cylinder cross-section area.
This is invented compared with prior art, and have the following advantages: little, in light weight, the whole device of (1) volume has only the 3-5 kilogram; (2) easy to install, need not change machine construction, do not influence existing operation; (3) applied widely, any four cylinder four-stroke and above internal-combustion engine all are suitable for; (4) fuel feeding is accurate, and sufficient combustion reduces pollution of atmosphere; (5) but fuel-economizing more than 10%.
