Abstract
An engine includes air-assisted fuel injection including fuel injectors supplying fuel through cylinder head-mounted air injectors. An internal air passage in the cylinder head connects with internal air pockets receiving the injectors and supplying them with air. Seals on the air injectors prevent air leakage from the air pockets. The air temperature in the head is affected by an adjacent coolant passage.
