摘要： A method is disclosed for making a transition from fueling an engine with hydrogen to another fuel. That other fuel may be gasoline, a gasoline and alcohol mixture, or gaseous fuels, as examples. The other fuel has the capability of providing higher BMEP than the hydrogen because of better air utilization and because the other fuel occupies less volume of the combustion chamber. Because a desirable equivalence ratio to burn hydrogen is at 0.5 or less and a desirable equivalence ratio to burn other fuel is at 1.0, when a demand for BMEP that leads to a transition change from hydrogen fuel to the other fuel, the amount of air supplied to the engine is decreased to provide more torque and vice versa. During a transition in which liquid fuel supply is initiated, it may be desirable to continue to provide some hydrogen, not leaner than 0.1 hydrogen equivalence ratio.

摘要： A four-stroke cycle, multi-cylinder reciprocating internal combustion engine (10) has a camshaft phaser (34) for adjusting the rotational position of the intake and exhaust camshafts (25, 26) with respect to the rotational position of the crankshaft (12) so that some of the cylinders (8) of the engine (10) may be deactivated. A common intake plenum (38) provides intake air to each of the cylinders (8) during normal engine operation, while an exhaust system (40) receives exhaust gasses from both the deactivatable cylinders (8a) as well as the other cylinders (8b). The cam phaser (34) adjusts the camshaft positions during cylinder deactivation operation such that the deactivated cylinders (8a) pump exhaust gas through the deactivated cylinders (8a) into the common plenum (38), which is employed by the still active cylinders (8b) as EGR gas.

摘要： A heat management system for an internal combustion engine utilizes recirculated liquid coolant and provides a heat intensifying circuit to hasten engine warm-up and a heat dissipation circuit for use after the engine has warmed to a predetermined operating temperature. When the engine is cold, it is operated in such a way as to maximize heat rejection to the coolant circulating in the heat intensifying circuit, which may include a heat exchanger for warming air within a passenger compartment of a vehicle. The present system optimizes the location of maximum heat transfer, minimizes the amount of coolant heated during the warm-up period and increases the heat transferred to this coolant. After the warm-up period the coolant system actively cools both the cylinder head and engine block surfaces and the engine operating strategy is returned for normal engine operation.

摘要： A system for controlling electromechanical of an internal combustion has a valve-closing electromagnet for attracting the armature coupled to the valve to close the valve, a valve-opening electromagnet for attracting the armature to open the valve, a valve-opening spring for biasing the valve open, and a valve-closing spring for biasing the valve closed. The method includes de-energizing the valve-closing electromagnet for a predetermined time, enabling the valve to oscillate by the valve springs, and then energizing the valve-closing electromagnet to close the valve. Consequently, only the valve-closing electromagnet is energized to open and close the valve. The valve biasing springs force the valve to a location at which the valve-closing electromagnet can close the valve. This provides an electrical energy over prior methods in which both the valve-opening and valve-closing electromagnets are energized to actuate the valve.

摘要： A fuel injection system used in the intake air passageway of an internal combustion engine has a strategy for reducing cold start hydrocarbon emissions. The fuel injector has an actuator which allows the fuel spray pattern to be varied from one which is widely dispersed and atomized to one which is only weakly dispersed. A strategy for varying the spray pattern during the engine warm-up period after cold start is disclosed. The strategy increases evaporation within the passageway so that cold start overfuelling and attendant hydrocarbon emissions are reduced.

摘要： A fuel injection system for a gaseous-fueled engine is provided. The fuel injection system comprises at least one gaseous fuel injector for each of the engine cylinders, wherein each fuel injector is located proximate the intake manifold. A guide tube connects each of the gaseous fuel injectors to at least one of the intake ports. The guide tube comprises a fluid passage arranged within the respective intake port substantially tangent and adjacent to an interior wall of the intake port and directed toward the respective intake valve. The guide tube is adapted to deliver high-pressure gaseous fuel from the injector to the respective combustion chamber along the interior wall of the intake port. In this way, the high velocity peripheral fuel charge creates a lower pressure central core within the intake part which, in turn, increases the overall intake charge flow and engine volumetric efficiency.

摘要： A variable displacement internal combustion engine having an intake manifold for providing ambient air and a boost manifold is provided. Either designated cylinders or selected cylinders may be operated in a non-firing mode wherein air may be compressed in a non-firing cylinder and ported to the boost manifold to provide boosted air pressure to firing cylinders. Each cylinder has an intake valve, an intake/compressed air valve, and an exhaust valve. The intake valves are controlled by electromagnetic actuators. The exhaust valve may be controlled by an electromagnetic valve actuator or a conventional valve actuator, if desired. Intake/compressed air valves of cylinders operating in the non-firing, compressor mode are ported to the boost manifold and selectively timed to provide compressed air to the boosted manifold when additional torque is desired provided that some of the cylinders are operating in the compressor mode.

摘要： A variable valve controlled engine causes the inducted exhaust residual to flow from the exhaust port(s) into specific regions of the combustion chamber and remain substantially separate from the air-fuel mixture, thereby creating stratification. The exhaust gas remains substantially on the piston surface and along the entire cylinder wall for at least a portion of the cylinder, with the air-fuel mixture occupying the remaining portion of the chamber.
