Title: Apply lubrication systems theory.
Course: Basic Small Engine Repair (20109) > Section: Diagnosing and Servicing 4-Cycle Engine

Application of theory should be based on knowledge of

- differences between 4- and 2-cycle lubrication
- effects of clearances on lubrication systems
- criteria for choosing lubricants
- types of lubricating systems, including splash, combination splash and force feed, force feed, and full force feed.

Process/Skill Questions:

- How does 4-cycle lubrication differ from 2-cycle lubrication?
- How is lubrication connected to clearances within the engine?
- How is the proper type of lubricant determined for different types of engines?
