Diesel Engine Technology PD730812
Topics: Powertrain & Propulsion Fuel injection , Engine mechanical components , Diesel / compression ignition engines
Regulations and consumer expectations have shaped the modern diesel engine. Enhancements have resulted in more power, fuel efficiency, reliability, and lower emissions, an indication that diesels will remain popular in the future. This technology is most widely used in commercial applications, such as trucking, shipping, construction, busing, and more. Each year, many light and medium duty car and truck manufacturers introduce diesel vehicles worldwide. A fundamental knowledge of diesel technology is critical for anyone involved in the diesel engine support industry.
The SAE Diesel Engine Technology eLearning course, featuring instructor Magdi Khair, begins with a brief but thorough history and introduction to diesel engines. It then covers the importance of the fuel injection system, air management systems, and other aspects of diesel engine combustion. It explains formation of each of the regulated emissions species with details of those emission control design changes, including some sample cases quantified through the use of actual examples. An overview of fueling diesels, developing technologies, and a comprehensive section on exhaust aftertreatment are also included.
