Horizontal engine

Abstract

The invention discloses a horizontal engine which is fixedly provided with a wing gathering plate. The wind gathering plate is located on the upper portion of the horizontal engine. A wedge-shaped space with the large front portion and the small rear portion is formed between the wind gathering plate and the horizontal engine. The wedge-shaped space is used as an air guide flue to be used for cooling the horizontal engine. The wind gathering plate is beneficial to gathering airflow flowing backwards and guiding the airflow to a cylinder body and a cylinder head. The overall cooling efficiency for the horizontal engine is greatly improved, it is ensured that the horizontal engine is good in product performance and long in service life, meanwhile, the horizontal engine is not greatly improved, one wind gathering plate is added to the cylinder body to cause small influences on the overall layout of a tricycle, the cost is low, the horizontal engine is suitable for the tricycle, and the product cost performance is greatly improved.

Description

technical field [0001] The invention relates to the field of motorcycles, in particular to a horizontal engine. Background technique [0002] Three-wheeled motorcycles are widely used due to their small displacement, small body size, and good passability. According to the industry, three-wheeled motorcycles are generally divided into elderly vehicles, regular three-wheeled trucks and passenger three-wheeled vehicles. 1. The body is small, suitable for the transportation of small items in family life. It is more flexible. The engine generally installed is a horizontal engine, which is beneficial to the coordinated layout of the structure. Facing the rear is good for driving to generate cooling air for cooling the engine. However, in daily use, horizontal engines use heavy loads, low vehicle speeds and high engine speeds, and there is a general problem of high heat load, especially for old horizontal engines. , speed up is slow, resulting in the inability to effectively dissi...

[0002] Three-wheeled motorcycles are widely used due to their small displacement, small body size, and good passability. According to the industry, three-wheeled motorcycles are generally divided into elderly vehicles, regular three-wheeled trucks and passenger three-wheeled vehicles. 1. The body is small, suitable for the transportation of small items in family life. It is more flexible. The engine generally installed is a horizontal engine, which is beneficial to the coordinated layout of the structure. Facing the rear is good for driving to generate cooling air for cooling the engine. However, in daily use, horizontal engines use heavy loads, low vehicle speeds and high engine speeds, and there is a general problem of high heat load, especially for old horizontal engines. , speed up is slow, resulting in the inability to effectively dissipate heat after climbing. Although there are cooling fins formed on the outer wall of the horizontal engine, due to the barriers formed between the cooling fins, the cooling wind generated by driving cannot effectively cool the heat between the cooling fins. , so that the heat dissipation efficiency of the horizontal engine is poor, and the engine is in a state of high temperature for a long time, which seriously affects the quality and service life of the engine. Of course, in order to overcome the problem of excessive engine temperature, it is also possible to change the cylinder head. Cover, box, left cover and right cover, etc., but the cost is relatively high, and it is not suitable for economical tricycles. Therefore, the above shortcomings seriously affect the application of horizontal engines
