The invention belongs to the technical field of design and manufacturing for marine engines, and specifically relates to a marine dual-fuel engine. According to the marine dual-fuel engine disclosed by the invention, a bypass valve is capable of selectively controlling low-temperature water to flow into an intercooler as needed, so that the intercooler is capable of cooling air to achieve a propertemperature according to the needs of various working conditions, thereby guaranteeing the cooling effect and increasing the energy utilization rate; and a crankcase breathing system is capable of separating lubricant oil steam in the waste gas of a crankcase from air, the lubricant oil steam is liquefied and then slides back to an oil sump, the separated air is conveyed into a turbocharger, mixed in an engine intake pipeline and consumed as a combustion-supporting gas for the engine, and a closed-loop breathing system is formed, so that the emission of the waste gas of the engine can be effectively reduced, and the combustion efficiency of the engine is increased.
Description
Technical field [0001] The invention belongs to the technical field of marine engine design and manufacture, and specifically relates to a marine dual-fuel engine. Background technique [0002] Compared with ordinary automobile engines, marine engines generally have the characteristics of large-scale and high-power. Therefore, various systems and structures need to be optimized and modified during the design and manufacture of marine engines. However, the current technology of marine engines still has poor cooling. , Low energy conversion rate, unstable structure and other defects. There is still room for further optimization. Summary of the invention [0003] The purpose of the present invention is to provide a marine dual-fuel engine with good cooling effect and high energy utilization rate. [0004] In order to achieve the above objective, the present invention provides the following technical solutions: [0005] A marine dual-fuel engine, comprising a body, and a cooling water ...
