I. A beginning automotive course designed to acquaint the student with four-stroke engines. Principles of operation, compression ratio, piston displacement, operating tolerances, valve timing, horsepower and torque development along with adjustments, inspection and troubleshooting procedures will be studied. A substantial portion of the class is devoted to laboratory exercises on laboratory engines.
