The invention discloses a common rail system suitable for a V-shaped dual-fuel engine, comprising a common rail support, a fuel oil rail, a fuel gas channel, a fuel gas inlet, a fuel oil inlet, a plurality of fuel gas injectors, a plurality of fuel gas common rail pipes, a plurality of fuel oil common rail pipes and a fixing assembly. The fuel gas inlet communicates with the fuel gas channel; the fuel oil inlet communicates with the fuel oil rail; a plurality of fuel gas outlets and fuel oil outlets are formed in the common rail support; inlets of the plurality of fuel gas injectors communicate with the fuel gas channel; the plurality of fuel gas outlets communicate with injection outlets of the plurality of fuel gas injectors; the plurality of fuel oil outlets communicate with the fuel oil rail; the plurality of fuel gas common rail pipes are detachably connected with the plurality of fuel oil outlets; the plurality of fuel oil common rail pipes are detachably connected with the plurality of fuel oil outlets; and the common rail support is located in the fixing assembly and detachably connected with the fixing assembly. The common rail system solves the problems that a gas and fuel system of an existing V-shaped dual-fuel engine is large in occupied space, needs a large number of pipelines, is complex in arrangement, is not convenient to overhaul, is prone to oil leakage and gas leakage and is damaged by external impact force.
Description
technical field [0001] The present application relates to the technical field of V-type engines, and more specifically, relates to a common rail system adapted to V-type dual-fuel engines. Background technique [0002] Since the V-type dual-fuel engine requires a gas injection system and a fuel common rail system, especially for a V-type engine with a compact structure, generally, the two systems need to occupy a large space, which does not meet the requirements of compact and high-strength engines. Considering the development trend of globalization, and considering that the V-type dual-fuel requires more pipelines, the layout of gas and fuel pipelines is relatively complicated, which is not convenient for maintenance and maintenance, and the dual-fuel engine involves two different fuels, so it is necessary to ensure that two Fuel safety, preventing damage to the common rail system caused by oil and air leakage and peripheral impact loads. [0003] Therefore, how to solve t...
