Numerical Analysis for Performance and the Combustion Reactants of the Crankcase Explosion Relief Valve

Abstract: A crankcase explosion relief valve (CERV) is installed to minimize the effects of explosions occurring in the crankcase of marine engines. According to the regulations of the International Association of Classification Societies (IACS), installation of CERV is mandatory and it must be designed and manufactured based on the engine size. As there are various types of engines, the CERV must be developed accordingly. A high cost is required for the explosion test in the development process, so the test is performe… Show more

“…Ignition can be promoted by any part of construction heated above 300-400 • C due to poor lubrication or by jets of hot combustion products escaping through piston rings or by electrostatic discharges. For minimizing the effect of explosion, marine engines must be equipped with crankcase relief valves [21][22][23] and flame arrestors [23,24].…”

“…2022, 10, x FOR PEER REVIEW 2 of 21 particular, these relate to the crankcases, the surroundings of the fuel injection system, the exhaust manifolds, the supply air accumulators, the sub-piston spaces, the turbochargers, and the starting air systems. The power rating of the largest, slow-speed, two-stroke crosshead engines exceeds 80 MW, which translates into the engine's dimensions and, potentially, the size of the consequences of its explosion [6]. Most marine engines-in fact, all large and high-powered engines-are starting to use compressed air.…”
