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.

Gaseous fuel direct injection system for internal combustion engines

A method for controlling fuel supplied to an engine includes steps of conducting tests on a representative model of a family of engines to obtain constants and coefficients of operating characteristics of the representative engine under ambient and induced temperatures and pressures, and creating look-up maps from which such coefficients may be obtained to compute actual operating conditions. When an engine is used in performance of normal operations, sensors are provided to determine actual operating temperatures and pressures which are used to select appropriate constants and coefficients for calculating engine fuel requirements in accordance with an algorithm, and using the calculated result to control flow to fuel to the engine under normal operating conditions.

Controlled dispersion of injected fuel

Knock control by reduction of injection period

In a spark ignition engine, fuel is injected directly into the cylinder volume. In order to obtain improved levels of combustion efficiency and reduced emissions the position of the fuel cloud within the cylinder volume is varied with engine load by controlled variation of fuel injection pressure. In particular, there is disclosed a method and apparatus for injection of fuel by compressed air where the position of the fuel cloud within the cylinder volume is controlled by conjoint control of fuel and air injection pressure. The invention has particular application to two-stroke cycle engines.

Fuel injection internal combustion engines

A method and apparatus of controlling the direct injection of fuel directly into the combustion chamber of an engine by a charge of gas, wherein the control of the timing of injection of the fuel includes at the commencement of start up of the engine, adjusting the timing of injection so injection occurs at a timing earlier in the combustion chamber cycle than the normal timing of injection for idle running; and in response to the engine reaching a predetermined speed or rotation during start up, the timing of injection is progressively adjusted each engine cycle towards the normal timing of injection at idle running.
