Introduction to four-stroke and auxiliary engines is a free online course that introduces you to the basic principles of camless engines, the camless engine design of B&W, the construction as well as the working of a stationary reluctance type torque sensor. The course also explains how to measure the torque as well as the Sulzers main diesel engines. The course will introduce you to the common rail concept in RT-Flex engine, and the working principle of a Sulzer RT-engine. The course will discuss the concept of performance assessment by indicator cards as well as the procedure for taking indicator diagrams. The course illustrates the types of indicator diagrams,and how the area of the indicator diagram can be calculated. Along with discussing the machinery performance monitoring process, and the illustration of the typical cylinder pressure measurement. The use of four-stroke engines in the marine industry, constructional features and components in a four-stroke engine, modern methods of creating indicator diagram, and how faults in the injection process can be determined, as well as how the indicator horsepower can be calculated, and how the shaft horsepower can be measured will be covered in this course.

The 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. This course also examines the concept of the MAN trunk piston engines, as well as the characteristics of the type VV 52/55 design. The course will discuss how the engine can be designed for residual fuel operation, and the features of the cylinder head and liner. The course explains the types and various components of the auxiliary marine diesel engine, the constructional features of the engine, and the broad classification of the auxiliary engine. The course outlines the important features of the fixed, moving, safety devices, as well as the lubrication oil system, and the exhaust gas turbocharging system in the auxiliary engine. The course examines the characteristics of the jacket cooling water system, the marine diesel engine four-stroke system, along with the piston oil flow process in the four-stroke diesel engine, and auxiliary engine.

Furthermore, this course will help you get familiar with the operation of the auxiliary engines, the speed governing mechanism, and operating troubles. The course will discuss the operational starting procedure of an auxiliary engine and various types of governors fitted on the auxiliary engine. The course explains the general maintenance of the auxiliary engine, the importance of cleaning the lube and fuel filters, as well as the crankcase inspection, the crankshaft deflection, and cylinder head mountings overhaul. The course also examines the inspection and maintenance procedures of the piston, and the connecting rod overhaul procedure in the auxiliary engine system. The course covers a wide scope of the cylinder calibration, inspection procedure, exhaust gas turbocharging system, and the exhaust gas turbocharger for auxiliary engines. The course will also detail the overhauling procedure of the fuel pump. The course will improve your understanding of the various systems in the auxiliary diesel engine, as well as the latest developments of the auxiliary engine. 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.
