Cold start strategy and system for gasoline direct injection compression ignition engine


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..

Method and device for operating an internal combustion engine


An internal combustion engine has a crankcase and a crankcase ventilation system having a switchable shut-off valve, and sensors that detect different operating parameters of the engine, including a load variable of the engine. An estimated load parameter is determined based on the different detected operating parameters using a dynamic model, and a corrective value of a characteristic value is determined as a function of a deviation between the estimated load variable and the detected load variable.
