Advanced Engines in Hybrid Electric Vehicles (HEVs)

Advanced Engines in Hybrid Electric Vehicles (HEVs)

The following module consists of a PowerPoint presentation, two lab sheets, and a syllabus for modifying automotive engine courses to include HEV technologies and was developed through a seed grant from the CAAT. The PowerPoint discusses the application of variable valve timing (VVT) and Atkinson cycle principals to HEVs, and the extra hydrocarbon capturing devices added to HEVs due to the use VVT and Atkinson principles. The lab "Compression Testing VVT systems" reinforces the ideas of the presentation illustrating engine malfunctions caused by a faulty VVT system. For additional insight on HEV engine service procedures, an oil change lab sheet for HEVs is included. For educators looking to modify current courses, the syllabus has highlighted fields where HEV technologies were incorporated to an engines course at Lewis and Clark Community College.
