Engines 3 – Diesel Engine Lubrication

Diesel engines operate under extreme conditions, with high loads, elevated temperatures, and exposure to combustion byproducts. Proper lubrication is essential for ensuring smooth engine operation, reducing wear, preventing deposit buildup, and meeting increasingly stringent emissions regulations. Selecting and maintaining the right diesel engine oil is critical to optimizing engine performance, extending service life, and reducing maintenance costs.

This course provides a comprehensive exploration of diesel engine lubrication, covering the fundamental principles of diesel engine operation, the role of lubricants, and the impact of emissions regulations on lubricant formulation. Participants will gain insights into industry specifications, oil formulation chemistry, and best practices for selecting and maintaining diesel engine oils. The course also delves into the workings of diesel engine lubrication systems and how modern emissions reduction technologies influence oil performance.

Designed for maintenance professionals, fleet operators, and lubrication engineers, this course equips participants with the knowledge to make informed decisions about diesel engine lubrication, ensuring reliability and compliance with industry standards.
