AM4009 Two and Three Wheelers Syllabus – Anna University PG Syllabus Regulation 2021

OBJECTIVE

The objective of this course is to make the students to
 analyse various two wheelers and their dynamics
 design the power unit of two and three wheelers
 apply the design aspects of transmission system
 understand different frames and suspension system used in two wheelers.
 Emphasize the knowledge on three wheelers and its sub systems
