Abstract
The utility model relates to an oil economizer for a gasoline engine. The utility model comprises a filter 1, a flange body 2, bushings 3, 5, and a partition board 4. A ring groove 13 is formed by the bushings 3, 5 and the flange body 2. The filter 1 is connected with one side of the flange body 2 and communicated with the ring groove 13, and the other end of the filter 1 is communicated with a crankcase ventilating pipe of a gasoline engine. The bushings 3, 5 are provided with a plurality of layers of small ventilating holes 11 including straight holes with different diameters and inclined holes in order to form a self-suction airflow passage. The crankcase ventilating gas enters the holes of the flange body through the ring groove 13 of the filter and the small holes 11 on the bushings. The oil economizer can make gas mixture mixed more uniformly, and the utility model has the advantages of complete combustion, good fuel-economizing effect and very little waste gas pollution.
Description
The utility model relates to a kind of fuel economizer, is applicable to automotive gasoline engine and is the various device of power with the petrol engine.
Chinese patent CN89213421 discloses a kind of automatic adjusting air oil mixed gas proportions of ingredients fuel economizer, constitute by flange body, edge cover and bleed self-regulated safety check, have oil-saving effect preferably characteristics with but this fuel economizer owing to introduced air, cause a series of problems:
(1). after introducing air, fuel air mixture is thinning, causes unstable idle speed.
(2). the discharging of petrol engine is past higher, even exceeds NBS.
(3). be subjected to certain influence vehicle dynamic quality.
(4). owing to introduce air, changed the degree of vacuum under the carburetor throttle, thereby do not matched, influenced the performance of motor with petrol engine igniting vacuum advance system.
The utility model is a deficiency of avoiding above-mentioned fuel economizer, adopt corrective measure, promptly abrogate the introducing air, change into and introduce crankcase ventilation gas, design a kind of simple in structurely, oil-saving effect is good, exhaust emission pollution is few and do not influence the fuel economizer of other performances such as petrol engine dynamic property.
The utility model reaches its purpose by following measure:
A kind of fuel economizer that is used for petrol engine, it is by being loaded on flange body 2 between gasoline engine carburetor and the intake manifold, being provided with ventilation annular groove 13 and breeder tube 11 and being sleeved on the edge cover 3,5 in flange body 2 endoporus and filter cleaner 1 and the isolating plate 4 that connects with flange body 2 being formed, it is characterized in that a filter cleaner 1 and a side of flange body 2 link by joint 10, and communicate with annular groove 13 between flange body 2 and the edge cover 3,5, annular groove divides two-part, and the centre has isolating plate 4 that annular groove 13 is cut off.
The utility model is compared with existing other technology to have and can be made the air combustion not have mixed gas to mix more evenly, burning and oil-saving effect are better, exhaust emission pollution characteristics still less, and do not influence other performance such as engine power performance, simple in structure, with low cost, can develop series product and use to be fit to the generalization of multiclass petrol engine.
Below in conjunction with accompanying drawing with further specifying.
Fig. 1 is the utility model overall structure figure.
Fig. 2 is Fig. 1 plan view.
Fuel economizer as shown in Figure 1, include the flange body 2 that is loaded between petrol engine carburetor and the intake manifold, the edge that is provided with breeder tube and is sleeved in flange body 2 endoporus overlaps 3,5, isolating plate 4 between the two edge covers, breeder tube 12 is arranged on the isolating plate, and filter cleaner 1 constitutes, it is characterized in that filter cleaner one end and crankcase bleed pipe join, the other end and flange body 2 one sides link to communicate with annular groove 13 and enter annular groove 13 from the crankcase ventilation gas of being introduced by the axle box ventilation duct by filter cleaner, breeder tube 11(on edge cover 3 comprises straight hole and inclined hole) formation jet and swirling flow, from the fuel oil that Carburetor comes, air Mixture is under the effect of above-mentioned jet and swirling flow, and mixed gas mixes better, atomizing effect is also better, it is just complete to burn, and to the engines fuel-economizing effect is improved, exhaust emission pollution reduces.
Fuel economizer of the present utility model as depicted in figs. 1 and 2, wherein filter cleaner 1 is made up of filtering body 8, joint 6,10 and filter screen 7,9, owing to contain impurity such as smog and oily vapour in the axle box ventilating gas of introducing, for avoiding that edge is put little hole plug, so added filter cleaner, petrol engine only needs the regular filter cleaner that cleans to get final product after loading onto this fuel economizer.
The utility model as shown in Figure 1 and Figure 2, fuel economizer is to be used for two-chamber transfer type Carburetor petrol engine, as the 492Q petrol engine, owing to two-chamber transfer type carburetor is not in most of the cases worked, thereby at two edge covers 3, add an isolating plate between 5, breeder tube 12 is arranged on the isolating plate, has so just increased the communicate by letter on-way resistance in secondary chamber of gas, make when do not work in secondary chamber, the gas overwhelming majority passes through from main chamber edge cover, has improved oil-saving effect.
Claims (4)
