Low-emission gasoline engine and preparation process thereof

Abstract

The invention discloses a low-emission gasoline engine and a preparation process thereof. The low-emission gasoline engine comprises an engine, an oil tank outer shell is fixedly installed on the outer surface of the top end of the engine through bolts, an oil pipe is connected between the oil tank outer shell and the engine, and an oil tank inner shell is welded to the inner surface of the engine. A reserved cavity is formed between the oil tank outer shell and the oil tank inner shell. According to the low-emission gasoline engine, the oil tank inner shell is installed in the oil tank outer shell, double-layer protection can be provided for use of an oil tank, when the oil tank inner shell is damaged, the oil tank outer shell can play a role in temporary protection, a foam plate is bonded to the inner surface of the oil tank outer shell, the space between the foam plate and the oil tank outer shell is filled with a flame retardant, when high temperature is generated in the oil tank, the foam plate melts, the flame retardant is mixed with gasoline, further combustion of the gasoline is prevented, the use safety is improved, the preparation process of the oil tank is simple, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the field of gasoline engines, in particular to a low-emission gasoline engine and a preparation process thereof. Background technique [0002] Low-emission gasoline engine is an engine that reduces exhaust emissions, but with the development of science and technology, people's requirements for low-emission gasoline engines are getting higher and higher, resulting in traditional low-emission gasoline engines that can no longer meet people's needs; [0003] There are certain disadvantages in the use of existing low-emission gasoline engines, (1), poor safety: when the existing low-emission gasoline engines are in use, because the fuel tank of the gasoline engine is exposed, the outer casing of the fuel tank is easily damaged by collision, making Gasoline leaks inside the fuel tank, which brings certain safety hazards; (2) It is impossible to detect whether the fuel tank is damaged: when the fuel tank for the existing low-emissio...

Problems solved by technology

[0002] Low-emission gasoline engine is an engine that reduces exhaust emissions, but with the development of science and technology, people's requirements for low-emission gasoline engines are getting higher and higher, resulting in traditional low-emission gasoline engines that can no longer meet people's needs;

[0003] There are certain disadvantages in the use of existing low-emission gasoline engines, (1), poor safety: when the existing low-emission gasoline engines are in use, because the fuel tank of the gasoline engine is exposed, the outer casing of the fuel tank is easily damaged by collision, making Gasoline leaks inside the fuel tank, which brings certain safety hazards; (2) It is impossible to detect whether the fuel tank is damaged: when the fuel tank for the existing low-emission gasoline engine is in use, if the fuel tank is damaged, the gasoline will leak, but it cannot be detected. It was discovered at the first time that the gasoline inside the fuel tank will further leak, which will bring greater safety hazards. Therefore, we propose a low-emission gasoline engine and its preparation process
