Fundamentals of diesel engines is an online course that introduces you to the operation of internal combustion engines and the thermodynamic cycles in diesel engines. Along with teaching you the theoretical cycle guiding the operation of modern diesel engines, we will compare how the OTTO, diesel and dual combustion cycle operated in diesel engines in the early 1900s. The course introduces the various classifications of diesel engines, the features of the piston stroke, and the characteristics of the supercharging or turbocharging terminology in marine diesel engines. You will learn essential terminologies applicable in a marine diesel engine. The course will also explain the timing diagrams of a diesel engine, the engine cycle, the complete series of separate steps or events essential for efficient engine operation, and how a diesel engine develops power by fuel combustion in its cylinders. Have you ever wondered how to calculate the power of an engine? This course touches on calculating the theoretical power and measuring the brake power of an engine with a hydraulic dynamometer.

Shipowners prefer single engine/single propeller designs. This course explains their reasoning, how the RTA96C-14 engine can achieve a maximum power output of 108,920 hp at 102 rpm, and how the engine exceeds 50% thermal efficiency at the maximum economy. Explore the vital component parts of the two-stroke engines, the construction of bedplate, frame box, cylinder frame, and the constructional features of the two-stroke engine, along with detailing the four-stroke engines used onboard ships. Discover the important parts of the engines, the constructional features of the marine two-stroke diesel engine, the major components in a two-stroke engine and how you can assemble the individual parts. In addition, the course explains the construction of the cylinder cover and the 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, and bearings of a two-stroke diesel engine.

Become an expert in the techniques for 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 continues by explaining 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. Learn how you can supply oil 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, and how the parts resist the pressures due to engine operation. The course demonstrates the internal forces resulting from engine fluctuations in torque, combustion gas forces, or guide forces. It then discusses how an engine structure offers rigidity and strength to ensure crankshaft stresses are minimal and maintain the perfect alignment of piston and running gear. This course will be of great interest to students, researchers, and anyone fascinated with diesel engines. So, register for this course and begin the learning process today.
