Basic Construction of Two Stroke Marine Diesel Engine
Section outline
-
This micro-credential course introduces learners to the fundamental components and construction of a two-stroke marine diesel engine. Designed for maritime and engineering students, the course covers essential parts such as the bedplate, piston, cylinder liner, crankshaft, and turbocharger. Learners will explore the function and interaction of each component within real shipboard systems. Through engaging visuals, self-paced quizzes, and technical references, this course aims to build a strong foundation in marine engine construction to support further learning in operation, maintenance, and troubleshooting of two-stroke diesel engines used in the maritime industry.
