Title: Method and device for diagnosing and controlling combustion instabilities in internal combustion engines operating in or transitioning to homogeneous charge combustion ignition mode

Abstract

This invention is a method of achieving stable, optimal mixtures of HCCI and SI in practical gasoline internal combustion engines comprising the steps of: characterizing the combustion process based on combustion process measurements, determining the ratio of conventional and HCCI combustion, determining the trajectory (sequence) of states for consecutive combustion processes, and determining subsequent combustion process modifications using said information to steer the engine combustion toward desired behavior.

  • A Homogeneous Charge Compression Ignition (HCCI) engine system includes an engine that produces exhaust gas. A vaporization means vaporizes fuel for the engine an air induction means provides air for the engine. An exhaust gas recirculation means recirculates the exhaust gas. A blending means blends the vaporized fuel, the exhaust gas, and the air. An induction means inducts the blended vaporized fuel, exhaust gas, and air into the engine. A control means controls the blending of the vaporized fuel, the exhaust gas, and the air and for controls the inducting the blended vaporized fuel, exhaust gas, and air into themore » engine.« less
  • A description is given of a method of and a device for controlling the output of an internal combustion engine. A mixture in an amount corresponding to the amount corresponding to the amount required for the full load operation of the engine is caused to flow into each cylinder in the suction stroke, even in the case of partial load operation. In the compression stroke, the amount of mixture required for the particular load of the engine remains in the cylinder, while the rest flows back into the suction system from the cylinder. (auth)
  • An injection device is described for injecting fuel into a combustion space such as an auxiliary combustion space of an external auto-ignition internal combustion engine of the type operating on the stratified-charge principle. The injection device includes a housing accommodating a movable pump plunger, a movable nozzle needle controlling the nozzle orifice opening into the auxiliary combustion space, and a movable piston-type storer. The pump plunger is configured to close off respective fuel return and fuel supply lines during its pumping stroke, at which time it effects a buildup of pressure resulting in movement of the piston type storer untilmore » a predetermined sufficient pressure is reached to force the nozzle needle away from the closed position to thereby effect injection of fuel into the auxiliary combustion space. An adjustable stop is provided at the piston-type storer and the supply fuel to the fuel supply line is under an adjustable pre-pressure, whereby the adjusted pre-pressure and the configuration of the piston-type storer control the amount of fuel injection.« less

The engine has a camshaft, a crankshaft, at least one intake valve and at least one piston, and is capable of providing for small valve events, and the engine providing for earlier than normal intake valve closings the method comprises: sensing the load demand on the engine, regulating the phasing of the operation of the camshaft of the engine with the operation of the crankshaft of the engine in response to the sensed load demand by advancingmore » the operation of camshaft relative to the operation of the crankshaft when a heavy load demand is sensed and by retarding the operation of the camshaft relative to the operation of the crankshaft when alight load demand is sensed, and sensing detonation in the engine and regulating the phasing operation of the camshaft relative to the operation of the crankshaft by advancing the operation of the camshaft relative to the crankshaft when detonation is sensed.« less
  • A method of operating an internal combustion engine with a split chamber design for stage combustion comprising the steps of: forming at least one primary combustion chamber and at least one secondary combustion chamber in association with a cylinder means having at least two regions formed therein and piston means within the engine, causing air within the cylinder means to flow through the at least one primary combustion chamber at a predetermined rate and volume; admitting a predetermined amount of fuel to the at least one primary combustion chamber to form a fuel/air mixture, therein; igniting the fuel/air mixture withinmore » the at least one primary combustion chamber to generate a first stage of combustion; causing the flow of the the ignited fuel/air mixture to the at least one secondary combustion chamber for continued burning of the fuel/air mixture in a second stage of combustion within the at least one secondary combustion chamber. This patent also describes a split chamber, staged combustion internal combustion engine. It comprises means defining a cylinder having at least two regions formed therein, piston means; combustion chambers; fuel delivery means; and means for igniting the fuel in the primary combustion chamber.« less
