Title: Air=fuel ratio control for direct injection IC engine - has blower in inlet manifold using heat from heated cylinder for improved vaporisation.
Inventor: HUBRICH DIETMAR
IPC: F02B39/10
Filed: 1991-09-30
Abstract: An axial blower (6) in the inlet manifold between the throttle valve and the cylinder creates a turbulent airflow into the cylinder and swirls the fuel/air mixture for a more even burn.
