Diesel Engine Basics
MODULE 2
In this module, we cover fundamental diesel engine principles, including core operating mechanisms, the evolution and functioning of various injection systems, cooling systems, turbochargers, and emissions reduction technologies.
In this lesson, we introduce the core operating principles of diesel engines, the functions of the main components, and the unique aspects of diesel fuel combustion, setting the stage for deeper exploration in subsequent lessons.
We explore conventional diesel injection systems, explain their mechanics and types, the importance of precise engineering in their function, and differences between direct and indirect injection.
We learn about the four operational cycles of a diesel engine - intake, compression, power, and exhaust - and the importance of timing and coordination for efficient engine operation.
We explain how to manage excess heat from the combustion process through water cooling systems, and briefly cover the distinctions and maintenance implications between wet and dry cylinder liners.
We learn how turbochargers enhance engine power by increasing air intake and oxygen, the intricacies of their operation and maintenance, and the trade-off between increased power and reduced engine life expectancy.
We address how regulations lead to innovations in emissions reduction technologies, and the implications of these complex systems for engine maintenance.
We discuss the evolution and benefits of high-pressure fuel injection systems, and the limits they impose when it comes to DIY maintenance.
