Summary
All diesel fuel injection equipment uses diesel as a lubricant to some extent. Excessive friction causes wear and tear to shorten the life of engine components such as diesel fuel injection pumps and fuel injectors. Diesel lubrication is one of the reasons. The experimental results of HFRR Lubricity Tester have a good correlation with the lubrication problems of diesel and related equipment, and can properly predict the lubricating performance of diesel.
