Abstract
A piston and injector system designed to minimize thermal loading on the cylinder head of an internal combustion engine. The piston features a profiled upper surface that defines an annular piston bowl with a primary bowl configuration and an asymmetric bowl sector. The asymmetric bowl sector is configured to receive the fuel spray from the injector, directing combustion to reduce heat concentration on certain areas of the cylinder head. This design helps prevent overheating, thereby enhancing engine durability and performance.
