Fundamentals of diesel engines is a free online course that introduces you to the operation of the internal combustion engines, the thermodynamic cycles in diesel engines. Along with teaching you about the theoretical cycle guiding the operation of modern diesel engines, and how the OTTO, diesel and dual combustion cycle operated in diesel engines in the early 1900s. The course will introduce you to the various classifications of diesel engines, the features of the piston stroke, characteristics of the supercharging or turbocharging terminology in marine diesel engines. You will learn about the important terminologies that are applicable in a marine diesel engine. The course will also explain the timing diagrams of a diesel engine, the engine cycle, the full series of separate steps or events essential for efficient engine operation, detailing how a diesel engine develops power by combustion of fuel in its cylinders. The theoretical power of an engine that is calculated from the indicated mean effective pressure, torsion meter engine in order for the flywheel to do effective work will be explained. You will learn how the brake power of an engine can be measured with a hydraulic dynamometer.

This course then explains why shipowners prefer single engine/single propeller designs, as well as how the RTA96C-14 engine can achieve a maximum power output of 108,920 hp at 102 rpm, and how at the maximum economy, the engine exceeds 50% thermal efficiency. The course explains the important component parts of the two-stroke engines, the construction of bedplate, frame box, cylinder frame, as well as the constructional features of the two-stroke engine. Along with detailing the four-stroke engines that are used onboard ships. The course will also outline the important parts of the engines, the constructional features of the marine 2 stroke diesel engine, the major components in a two-stroke engine, and how the individual parts can be assembled together. The course explains the construction of the cylinder cover, mountings of a two-stroke diesel engine, including the features of the safety valve, fuel valves, indicator valves, and how the cylinder cover seals the upper end of the cylinder space. The course will also teach you the constructional features of the crosshead, connecting rod, as well as bearings of a two-stroke diesel engine.

Furthermore, this course will help you get familiar with the ways or techniques of using the crosshead in large two-stroke marine diesel engines to ease the side thrust by reducing the liner wear in the engine. The course explains the concept of the Sulzer RTA engine connecting rod, the process of the cross-head bearing, the features of the Sulzer engine bearings and lubrication. Along with how oil can be supplied to the crosshead through telescopic pipes in MAN B&W engines. The course examines the engine structure, fixed parts that hold the engine together, support and keep the moving parts in alignment, as well as how the parts resist the forces due to engine operation. The course explains the Internal forces that occur due to engine fluctuations in torque, combustion gas forces, or guide forces. The course will discuss how an engine structure offers rigidity and strength to ensure crankshaft stresses are minimum and Maintain perfect alignment of piston and running gear. This free online course will be of great interest to students, researchers, and anyone with an interest in diesel engines. So, register for this course and start your next learning journey today.
