Engine Cooling and Lubrication Systems
Course Highlights

This online engineering PDH course describes the cooling and lubrication systems for internal combustion engines.


An internal combustion engine produces power by burning fuel within the cylinders; therefore, it is often referred to as a "heat engine." However, only about 25% of the heat is converted to useful power. Thirty to thirty five percent of the heat produced in the combustion chambers by the burning fuel is dissipated by the cooling system along with the lubrication and fuel systems. Forty to forty-five percent of the heat produced passes out with the exhaust gases. If this heat were not removed quickly, overheating and extensive damage would result. Valves would burn and warp, lubricating oil would break down, pistons and bearings would overheat and seize, and the engine would soon stop.


The necessity for cooling may be emphasized by considering the total heat developed by an ordinary six cylinder engine. It is estimated that such an engine operating at ordinary speeds generates enough heat to warm a six-room house in freezing weather.


This 4 PDH online course is applicable to mechanical and automotive engineers, mechanics, and technical personnel who are interested in gaining a basic understanding of cooling and lubrication systems of internal combustion engines.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the relationship of the cooling system and engine operation
  • Identifying design and functional features of individual cooling system components
  • Identifying maintenance procedures applicable to cooling systems
  • Identifying types of lubrication systems used
  • Understanding operational characteristics and maintenance requirements of lubrication systems.
