Course Information
Description
This course will include overviews of mechanical and electronic fuel systems and their related components primarily found on diesel engines. Students will diagnose, service, and repair fuel systems equipped on both on-highway and off-highway applications. An overview of the relationship of the fuel system to the aftertreatment system will be discussed. Also included are safe work habits and features of emerging alternative fuel sources.
