The internal combustion engine is a machine made up of thousands of parts all intricately working together to yield power. One part, the piston rings, are vital to separating the combustion chamber and crankcase, perhaps holding the most important job of all. Upon completion of this course, learners will:
- Have a foundation in piston ring terminology and layout in internal combustion engines.
- Be able to describe the function, design features, materials and coatings as applied to compression and oil control rings in two and four stroke engines.
- Be able to describe axial ring dynamics in the two compression rings in engine operation ring sealing issues.
- Be able to identify both blow-by and oil consumption mechanisms and ways of mitigation for each.
- Will understand the challenges and approaches to ring and cylinder wall wear validation, measurement and modeling in two and four stroke internal combustion engines.
Ultimately, this course will arm learners with critical knowledge of internal combustion piston ring design considerations and wear measurement/mitigation techniques
Who Should Attend?
