While studying the four stroke cycle", students will be able to classify engines based on cylinder number, configuration and/or valve train design. Students will trace engine lubrication and cooling systems as well as understand the causes of wear and part failure. Students will also become familiar with the concepts of volumetric efficiency, horsepower and torque. In addition, students continue to develop and practice skills related to hazardous waste disposal, and avoidance of potential shop hazards.
