초록 ▼

A gaseous fuel direct injection fuel system for a spark ignited internal combustion engine having an inlet port for admitting combustion air into a combustion chamber of the engine, the direction injection system including at least one fuel injector for directly injecting gaseous fuel into the combustion chamber, and means for supplying gaseous fuel to the fuel injector, a quantity of gaseous fuel being injected into the combustion chamber by the fuel injector, wherein at least at some operating condition thereof, the injection of the gaseous fuel is initiated after the closing of the inlet port, and wherein the injection of the gaseous fuel is completed before the compression stroke of the engine is substantially completed.

대표청구항 ▼

[ We claim:] [1.] In a direct injection gaseous fuel system for a spark ignited internal combustion engine having an inlet port for admitting combustion air into a combustion chamber of the engine, the direct injection system including at least one fuel injector means and supply means for supplying said fuel to the fuel injector, the fuel injection means for directly injecting a quantity of fuel which is a compressed gas fuel or a liquified gas fuel into the combustion chamber, the improvement comprising said fuel injection means also for completing injection of said fuel before the compression stroke of the engine is substantially completed, and for, during at least some engine operating conditions, initiating injection of said fuel after the closing of the inlet port while controlling the quantity of gaseous fuel being injected into the combustion chamber as a function of both the timing and duration of the injection of the gaseous fuel.
