摘要： An engine assembly includes an engine with an engine block having at least one cylinder. A crankshaft is moveable to define a plurality of crank angles from a bore axis defined by the cylinder to a crank axis defined by the crankshaft. The plurality of angles includes a crank angle (CA50) corresponding to 50% of the fuel received by the cylinder being combusted. A controller is operatively connected to the engine and has a processor and a tangible, non-transitory memory on which is recorded instructions for executing a method for controlling the combustion phasing in the engine during a transient state. The controller is programmed to generate a learned table by storing at least one combustion phasing parameter in the tangible, non-transitory memory. Combustion phasing during a transient state is controlled based at least partially on the learned table.

摘要： A method for starting a compression ignition engine having at least one cylinder with a reciprocating piston located therein, an intake valve configured to control the intake of air to an intake port of the cylinder and an exhaust valve configured to control the expulsion of gas from an exhaust port of the cylinder. The method includes the steps of: cranking the engine, conditioning intake air at the intake port of the cylinder to raise the temperature of air in the cylinder, controlling a valve timing the intake valve and/or the exhaust valve to allow the piston to compress the air within the cylinder, thereby increasing the temperature of the air within the cylinder, and injecting fuel into the cylinder when the air within the cylinder has been heated to a temperature sufficient to support compression ignition of a gasoline and air mixture within the cylinder.

摘要： An internal combustion engine control apparatus includes a fuel injection apparatus injecting fuel into a combustion chamber a plurality of times during a single cycle, and controls an internal combustion engine that performs compression combustion. The internal combustion engine control apparatus includes an injection command unit and an injection specification determining unit. The injection command unit commands the fuel injection apparatus to perform: a main injection for a main combustion that generates torque; and a preceding injection that is performed at a stage before the main injection. The injection specification determining unit determines a penetration force of a spray produced by the preceding injection or an injection direction of the preceding injection, such that a range of reach of the spray produced by the preceding injection is closer to a nozzle hole of the fuel injection apparatus than a range of reach of a spray produced by the main injection.

摘要： A dual fumigation homogeneous charge compression ignition (DF-HCCI) engine runs on low volatility internal combustion (IC) engine fuel such as diesel in combination with another IC engine fuel, both simultaneously fumigated in engine intake air stream. Both fumigated fuels mix with engine intake air and they are inducted together, at the same time, into engine combustion chamber where homogeneous charge compression ignition combustion takes place. Fumigation of two fuels, in which one fuel has low volatility, is done by a novel dual fuel fumigation system comprising of at least one ultrasonic atomizer. Combustion phasing control is done by varying proportions of fumigated fuels, EGR rate, and EGR temperature and additionally by controlling engine intake air temperature. Engine intake air is controlled to a desirable temperature by heat exchanger utilizing heat from engine and/or exhaust gas. A controller monitors inputs from relevant sensors and, based on these inputs, adjusts fumigation rates of fuels, EGR rates, EGR temperature and engine intake air temperature.

摘要： An internal combustion engine comprising the fuel injector arranged in the combustion chamber. The primary fuel injection and the secondary fuel injection from the fuel injector are successively performed to cause autoignition of an injected fuel of the primary fuel injection and autoignition of an injected fuel of the secondary fuel injection. A temperature region suppressing change of an ignition delay time where a change of ignition delay time with respect to a rise in temperature in the combustion chamber is suppressed appears in the compression stroke at a temperature in the combustion chamber of 700K to 900K. The secondary fuel injection is performed if the temperature in the combustion chamber is a temperature within the temperature region suppressing change of the ignition delay time during the compression stroke. The primary fuel injection is performed during the compression stroke or suction stroke before the temperature in the combustion chamber reaches a temperature in the temperature region suppressing change of the ignition delay time at a fuel injection timing at which the injected fuel of the secondary fuel injection is autoignited after the injected fuel of the primary fuel injection is autoignited.

摘要： An internal combustion engine is described. Controlling the internal combustion engine includes gathering engine operating data during steady-state engine operation, including gathering a first dataset associated with a cylinder air charge during steady-state operation of the engine in the PVO state and gathering a second dataset associated with a cylinder air charge during steady-state operation of the engine in the NVO state. An optimization routine is executed to determine a first subset of parameters associated with a first relationship for a cylinder air charge model based upon the second dataset. The optimization routine is also executed to determine a second subset of parameters associated with a second relationship for the cylinder air charge model based upon the first dataset. A cylinder air charge is determined in real-time during engine operation based upon the cylinder air charge model and the first and second subsets of parameters.
