The unit fuel injector disclosed is directly mountable on cylinder heads in an internal combustion compression ignited engine. The device includes a housing with a spring-biased cam operated reciprocating piston mounted therein. The ported piston has a constant length stroke in the two embodiments disclosed. The quantity of fuel injected on each constant length stroke is determined by a movable ported sleeve member in which the piston reciprocates. Fuel is supplied to the unit fuel injector through appropriate porting in the cylinder head in a conventional manner.
