Abstract

The invention discloses an air inlet structure for a dual-fuel engine. The air inlet structure comprises an air inlet pipe and a fuel air inlet manifold. The fuel air inlet manifold is connected with a valve piece box through a fuel air inlet branch pipe. The fuel air inlet manifold comprises an outer air inlet manifold body and an inner air inlet manifold body. The fuel air inlet branch pipe comprises an outer air inlet branch pipe body and an inner air inlet branch pipe body. One end of the outer air inlet branch pipe body is connected with the outer air inlet manifold body, and the other end of the outer air inlet branch pipe is connected with a cover plate of the valve piece box. One end of the inner air inlet branch pipe body is connected with the inner air inlet manifold body, and the other end of the inner air inlet branch pipe body is connected with a fuel gas inlet connecting pipe extending in the valve piece box. At least one fuel gas jetting valve communicated with the inner air inlet branch pipe body is arranged in the valve piece box, wherein a nozzle is arranged on the fuel gas jetting valve and extends in the air inlet pipe. The air inlet structure for the dual-fuel engine has the advantages of being simple and compact in structure, safe, reliable and high in combustion efficiency, and therefore the energy utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction of internal combustion engines, in particular to an intake structure of a dual-fuel engine. Background technique [0002] As the main prime mover, the internal combustion engine is widely used in human society. With the increasingly prominent problems of energy shortage and environmental pollution, countries are actively carrying out research on energy-saving and emission-reduction technologies for internal combustion engines. In the field of marine diesel engines, the research and application of dual-fuel and pure gas engine technology can effectively improve economy and reduce the emission of harmful substances such as NOx and particles. [0003] Diesel engines are widely used due to their wide power coverage and high thermal efficiency. However, due to the large amount of harmful emissions of exhaust gas from pure diesel engine fuel combustion, it is one of the imp...
