ABSTRACT To explore the measures that can be used to improve the fuel economy of internal combustion engines, we investigated how friction at the piston ring-cylinder liner interface is influenced by ...

Aiming at the improvement in piston lubrication and the reduction of piston friction loss under this study, piston friction forces of cylinders with different surface roughness and treatment methods ...

No experienced engine builder would intentionally bolt a cylinder head to an engine block without installing a gasket between the block and cylinder head. The gasket seals the block-deck surface to ...

This paper explains the mechanisms that affect lubricating oil consumption in stationary gas engines. It explains the positive and negative consequences of oil consumption. It discusses the importance ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

When two metallic surfaces under direct contact move over each other, they create friction which generates heat. This causes excessive wear and tear of those moving parts. However, when a film of ...

Modern engines are packed with technology, yet the core hardware still follows a simple logic: air and fuel go in, power comes out, and heat must be controlled. When I understand the main components ...
