Abstract
The utility model provides a general gasoline engine which comprises an air filter, an oil tank and a silencer, wherein the top part of the air filter is provided with an air filter cover. The general gasoline engine is characterized in that the air filter and the oil tank are arranged in the shape of Chinese character 'yi', and the silencer is horizontally positioned at one side of the air filter and the oil tank. As the air filter and the oil tank are arranged in the shape of Chinese character 'yi', the silencer is horizontally positioned at one side of the air filter and the oil tank, the air filter, the oil tank and the silencer are arranged in a rectangular shape so as to change the structure in the shape of Chinese character 'pin' in prior art, therefore, the general gasoline engine has compacter structure, and simultaneously a lengthened space is also provided for the silencer; and by increasing the length of the silencer, a silencing effect can be improved so that noises are reduced.
Description
Technical field
The utility model relates to engine art, relates in particular to general gasoline engines.
Background technique
General gasoline engines has advantages such as volume is little, in light weight, easy to use, and it is widely used in various farm machineries, for microtilling machine, water pump, lawn machine, generator etc. provide power source.The top of general gasoline engines is provided with free filter, fuel tank and silencing apparatus, be " product " font structural configuration between empty filter, fuel tank and the silencing apparatus of general gasoline engines in the market, make that the length of existing silencing apparatus is shorter, on the one hand, for keeping the integrally-built compactness of general gasoline engines, its silencing apparatus does not have the space of lengthening, and good more along with its noise elimination effect of growth of its length with the silencing apparatus of spline structure, the noise elimination effect of therefore existing general gasoline engines is relatively poor, and noise is bigger.On the other hand, the suction port of existing empty filter is opened in the bottom of sky filter, and floor-dust enters into the Carburetor that is arranged in the sky filter from suction port easily, thereby causes Carburetor oil leakage phenomenon to occur.
The model utility content
The technical problem that the utility model solves is:
1, provides a kind of and can increase the length of silencing apparatus and the general gasoline engines of compact structure.
2, provide a kind of and can prevent effectively that dust from entering into the general gasoline engines of Carburetor.
The technical solution of the utility model is: a kind of general gasoline engines, comprise sky filter, fuel tank and silencing apparatus, the top of described empty filter is provided with sky filter lid, it is characterized in that, described empty filter and described fuel tank are " one " font to be arranged, and described silencing apparatus level is positioned at a side of sky filter and fuel tank.
One end face of described silencing apparatus is concordant with the end sides of described empty filter, and the other end of silencing apparatus is concordant with the end sides of described fuel tank.
Described empty filter lid comprises end cap portions, is threaded into the round platform portion of portion and hollow, described round platform portion is positioned at described end cap portions and described being threaded between the portion, the upper bottom surface diameter of round platform portion is greater than the bottom surface diameter, the ring-side wall of round platform portion has suction port, and this suction port exposes the top of described empty filter.
The end face of described fuel tank has a depressed part, and this depressed part is provided with oil filler; The end face of described empty filter has the extension board that extends towards the fuel tank direction, and this extension board drops in the depressed part of described fuel tank, and the oil filler of fuel tank passes from the extension board of empty filter.
The beneficial effects of the utility model are:
1, because empty filter and fuel tank are the arrangement of " one " font, the silencing apparatus level is positioned at a side of sky filter and fuel tank, empty filter, fuel tank and the rectangular arrangement of silencing apparatus, changed " product " word structure of prior art, the structure of general gasoline engines is compact more, also provides the space of lengthening simultaneously for silencing apparatus, by increasing silencing apparatus length, thereby can improve the effect of noise elimination, reduce noise.
When 2, general gasoline engines was worked, the dust on work ground can upwards be kicked up, because the suction port of empty filter is changed the top that is located at the sky filter, can prevent that dust from entering into the Carburetor that is arranged in the sky filter from suction port, had avoided Carburetor to produce oil leakage phenomenon.
