Understanding Diesel Fuel Injector Lubrication and Cooling

Discover how diesel fuel injectors are lubricated and cooled for enhanced performance.

56 views

Diesel fuel injectors are lubricated by the diesel fuel itself, which provides the necessary lubrication to reduce friction while passing through the injectors. They are cooled through the circulation of fuel and in some cases, via engine coolant that flows around the injector sleeves. Regular maintenance and clean fuel ensure the efficiency and longevity of the injectors, preventing overheating and wear.
