An internal combustion engine 1 at a standstill of a vehicle after cold starting can switch its combustion mode to a homogenous combustion mode or a stratified combustion mode. An operation range of the stratified combustion at the standstill of the vehicl...

An engine control system (50) for a vehicle (1), which is configured to control an engine (14) using a plurality of control modes, comprising a controller (19) configured to selectively set a first control mode or a second control mode and to control the e...

An internal combustion engine controller for automobiles which realizes torque increasing performance and exhaust gas purifying performance in a well-balanced manner even when a high-response torque increase is demanded in uniform charge stoichiometric com...

The present invention relates to a control system and to a control method which are applied to a motor vehicle including an internal combustion engine and a motor connected to an output shaft of the internal combustion engine, and which is operable to perf...

The electronic control unit (50) sets an initial value of an inertia torque equivalent flow rate Qmg as an air flow equivalent to an inertia torque that acts on rotational elements related to a crankshaft (26), and a diminishing rate thereof, based on a sh...

A method and system may be provided to perform a process for controlling power provided by an engine (120) in a machine (100). In one embodiment of the invention, the process may include determining a first power value reflecting a predetermined first powe...

The present invention is directed to a method and device for operating an engine (1) of a motor vehicle. Firstly, driving condition parameters of the engine (1) and/or the motor vehicle are captured over a predetermined period of time. After that the proba...

A method for obtaining an accurate cylinder air-charge estimate is presented. First, a sensor-based powertrain. torque estimate is obtained. Next, a torque converter-based powertrain torque estimate is obtained when the torque converter clutch is unlocked....

A method and apparatus for determining a volatility of a fuel sample. A fuel sample is collected in a container (22) and heated for a time period using a heater device (24). Periodically during the heating, the capacitance of the fuel sample and the temper...
