Description

Technical Field

[0001] The utility model relates to the technical field of methanol fuel engines, in particular to a marine methanol fuel engine. Background Art

[0002] Compared with diesel, methanol fuel can greatly reduce the emission of SOx, NOx and particulate matter. It is a clean fuel with good economy. When the marine methanol fuel engine is working, there is always a part of the combustible mixture and exhaust gas into the crankcase through the piston ring. The methanol fuel vapor that enters the crankcase will condense and make the engine oil thinner, resulting in a significant reduction in performance. The exhaust gas contains water vapor and sulfur dioxide. The water vapor condenses in the engine oil to form foam, which destroys the engine oil supply. This phenomenon is particularly serious in winter. Sulfur dioxide generates sulfurous acid when it meets water, and sulfurous acid generates sulfuric acid when it meets oxygen in the air. These acidic substances not only deteriorate the engine oil, but also corrode the parts. As the combustible mixture and exhaust gas enter the crankcase, the pressure in the crankcase will increase, causing the engine oil to leak out from the crankshaft oil seal, crankcase gasket, etc. and lose. However, the engine oil vapor lost to the atmosphere will aggravate the pollution of the atmosphere.

[0003] At present, methanol fuel engines are equipped with different forms of ventilation devices, some of which are directly ventilated by drilling holes on the engine fuel filler cap, some of which are ventilated by using ventilation exhaust pipes equipped with filters on the cylinder body or cylinder head cover, and some of which are ventilated by connecting the cylinder head cover with the intake pipe. However, no matter which ventilation method is used, it cannot remove the chloride ions in the air, which leads to the phenomenon that when the methanol fuel engine is used on a ship, its chloride ions will flow into the methanol fuel engine, which will corrode the internal structure of the methanol fuel engine over time, thereby affecting the service life and performance of the methanol fuel engine. Therefore, a marine methanol fuel engine is invented. Summary of the invention
