Gasoline engine for snow sweeper

Abstract

The invention provides a gasoline engine for a snow sweeper, which comprises a silencer, a face guard, a carburetor and a cylinder body, wherein the silencer is provided with a silencer chamber, a silencer housing, a silencer intake pipe and a spark arrester; the silencer chamber is arranged in the silencer housing and is a cavity formed by a silencer chamber lower shell and a silencer chamber upper shell; the silencer intake pipe penetrates through the silencer chamber lower shell and extends upwards; the upper end part of the silencer intake pipe is installed on the inner wall surface of the silencer chamber upper shell; the upper end of the face guard is connected with the lower part of the silencer housing, and the lower end of the face guard is connected with the cylinder body; a space, the upper part of which is communicated with the silencer, is formed between the face guard and the cylinder body; an air filter is omitted at the air inlet of the carburetor; and the carburetor and the air inlet of the carburetor are positioned in the space enclosed by the face guard. By using the structure, the invention inhibits the temperature rise of the silencer, avoids scalds, increasesthe air temperature at the air inlet of the carburetor, and improves the ignition performance and the power performance.

Description

technical field [0001] The invention relates to a gasoline engine for a snowplow, in particular to a gasoline engine for a snowplow with an improved muffler and an air intake structure. Background technique [0002] Existing snowplow gasoline engine is provided with carburetor, and the effect of carburetor is according to the needs of gasoline engine in different situations, gasoline is atomized, and is mixed into combustible mixture with air in a certain proportion. An air filter is generally installed at the air intake of the carburetor. The main function of the air filter is to filter the dust and sand in the air. On the one hand, it prevents the dust in the air from blocking the carburetor, and on the other hand, it prevents the dust and sand in the air from entering the cylinder and causing severe wear of the gasoline engine. Snowplows generally work in snowy days around -30°C, and the air in snowy days around -30°C is already very clean, basically no longer containing...

AI Technical Summary

Problems solved by technology

However, in the technical solution of the above-mentioned utility model patent, structures such as a wind deflector, an air deflector, an air collection channel, and an air deflector are arranged to form an air deflector, which complicates the structure of the gasoline engine for snowplows and requires processing and More parts to repair and higher costs

At the same time, the gasoline engine for snowplows disclosed in this utility model patent only changes the structure of the air guide, but does not change the structure of the muffler. Although the muffler is cooled to a certain extent by the air guide device, the cooling effect is limited.

In practice, after using the gasoline engine for snowplows for a long time, the temperature of the muffler will be too high and the operator will be scalded.
