Motorcycle engine oil external circulation system

Abstract

The invention discloses a motorcycle engine oil external circulation system, an engine is located at the rear part of a forward inclined tube of a motorcycle frame, the forward inclined tube and the upper end of the main beam tube of the motorcycle frame are both fixed with a stand tube of a motorcycle head, a reinforcement tube is arranged between the forward inclined tube and the main beam tube, an oil storage tank is arranged in the zone formed by the stand tube, the forward inclined tube, the main beam tube and the reinforced tube, the side of the oil storage tank is provided with an oil inlet which is connected with the oil outlet of the engine through an oil inlet tube; and the oil storage tank is communicated with the inner cavity of the forward inclined tube, an oil outlet is arranged at the bottom end of the forward inclined tube which is communicated with the return opening of the oil storage tank. The invention not only increases the loading capacity of engine oil, prolongsthe service life of the engine oil and improves the passing ability of the whole motorcycle, but also can significantly reduce the cylinder temperature of the engine and the oil temperature, improvesoperating conditions of the engine, improves engine power, has the characteristics of ingeniously conception, simple structure, good reliability, strong versatility and the like, thus being capable of being used on various types of motorcycles.

Description

technical field [0001] The invention belongs to the technical field of motorcycles, and in particular relates to a motorcycle engine oil external circulation system. Background technique [0002] The frame is the main skeleton of the motorcycle, which is welded by pipe fittings and plays the role of installing and supporting the parts of the motorcycle. However, the internal cavity of the pipe fittings of the frame is not equipped with any parts, and is completely empty and has not been effectively used. use. The engine is mounted on the frame, and the engine oil required for the normal operation of the engine is loaded by the cavity of the engine housing. The amount of engine oil loaded is limited by the size of the engine. The amount of engine oil is generally small, and the oil only circulates inside the engine, so that the oil cannot be effectively cooled when the engine is working (especially for large displacement engines), which is likely to cause oil temperature and...

AI Technical Summary

Problems solved by technology

The amount of engine oil loaded is limited by the size of the engine. The amount of engine oil is generally small, and the engine oil only circulates inside the engine, so that the oil cannot be effectively cooled when the engine is working (especially for large displacement engines), which is likely to cause oil temperature and engine damage. If the temperature of the cylinder head is too high, on the one hand, the engine oil will deteriorate due to high temperature and shorten the service life of the engine oil; engine damage

In addition, the engine oil chamber where the engine is loaded with oil is located at its lower part, which makes the lower part of the engine protrude larger, which is not convenient to improve the trafficability of the whole vehicle
