Problems solved by technology

Existing dual-fuel engine fuels are all modified slightly on the basis of gasoline engines to match fuels such as natural gas or alcohols. The purpose is to save energy, but the result is that the power performance is lost, and its power performance is greatly reduced after burning. It can only be applied to a small range of urban roads, but complex mountain roads cannot be applied due to dynamic constraints

Abstract

The invention provides a dual-fuel automobile engine applied to the field of engines. The dual-fuel engine comprises a cam shaft (1), a high-pressure oil rail (7) and a piston connecting rod mechanism (10). The dual-fuel engine also comprises a speed-reducing gear (3), a chain wheel I (5), a chain wheel II (6) and a driving gear (9). The driving gear (9) is connected with the cam shaft (1); the driving gear (9) and the chain wheel II (6) are arranged in a disconnected or connected mode; the speed-reducing gear (3) is engaged with the driving gear (9); and the speed-reducing gear (3) and the chain wheel I (5) are arranged in a disconnected or connected mode. Due to the adoption of the structure, the dual-fuel engine can consume gasoline or diesel to meet the different requirements on road conditions and power. Therefore, the dual-fuel engine can use the gasoline and the diesel as fuel, use the other kind of fuel when one kind of fuel is insufficient, prolong the continued mileage of vehicles and enhance the adaptivity of the vehicles to special environment.

Description

technical field [0001] The invention relates to the field of engines, and more specifically relates to a dual-fuel automobile engine. Background technique [0002] At present, the automobile engines on the market are mainly divided into two categories, one is diesel engine, the other is gasoline engine, the two fuels cannot be mixed with each other, and each body has been optimized to a high degree, so for different engine types , can only use different fuels, but also brings their own inherent advantages and disadvantages: [0003] Gasoline engine has low thermal efficiency, high speed, high fuel consumption, and small torque, and is suitable for urban roads with good road conditions; diesel engine has loud noise, low speed, low fuel consumption, and large torque, and is suitable for mountain roads with complex road conditions; [0004] Therefore, foreign countries have been committed to researching a kind of mixed fuel engine, which can burn a variety of fuels. Combining ...
