Abstract

The subject matter described herein is directed to a cylinder head assembly (115) for a compression-ignition engine (100). The cylinder head assembly (115) includes a cylinder head (125) having a combustion bowl (410). A combustion chamber (405) is formed between the combustion bowl (410) and a piston (110) movably disposed inside a cylinder (105). The cylinder head assembly (115) also includes an injector (135) mounted on the cylinder head (125) to inject fuel in the combustion chamber (405). Further, a plurality of orifices are arranged radially on the injector (135) such that the injected fuel has a substantially disc shaped spray-pattern (520).
