The invention relates to an internal combustion engine of a motor vehicle in which a device for modifying valve behavior is configured so that at least one exhaust valve of at least one cylinder exhibits different kinetics during an initial volume reductio...

An internal combustion engine (1) includes an intake variable lift amount mechanism (14i) that changes a maximum lift amount and valve-open period of an intake valve (9), and an exhaust variable lift amount mechanism (14e) that changes a maximum lift amoun...

A method for operating an internal combustion engine with a combustion engine, a fresh gas line, an exhaust line comprising an actively regenerable exhaust aftertreatment device, wherein for a cylinder of the combustion engine the supply of fresh gas is co...

Valve stopping control is performed that changes an operating state of an intake valve (28) and an exhaust valve (30) to a closed-valve stopped state when executing a fuel-cut operation. A device is provided that sets an in-cylinder return-time target air-...

An engine control apparatus includes a target air volume calculator (2b) which calculates a target air volume required by an engine (10), and an actual air volume calculator (2a) which calculates an actual air volume inhaled into a cylinder (19) of the eng...

A combustion timing prediction method for a compression self-ignition internal combustion engine includes the steps of: specifying types of a plurality of hydrocarbon components contained in a hydrocarbon fuel and proportions of the respective types in the...

An intake control apparatus for an internal combustion engine (51) includes a variable valve operating mechanism (11) capable of varying a lift and operation angle of an intake valve (53) continuously and a control unit (69) that controls an intake air amo...

Method for checking the functionality of a device for adjusting the stroke of a combustion engine gas exchange valve involves measurement of the exhaust gas composition using a sensor, e.g. a lambda sensor, and then evaluation of the composition.

A control system for an internal combustion engine in which a valve timing is switched between a low-speed (LO-V/T) or high-speed (HI-V/T) valve timing within a lean-burn control range established in accordance with the operational state (an intake pipe in...

The method calculates the mass flow of air supplied to the engine cylinders from the air intake by measuring the mass flow rate (rlroh) in the air intake and subtracting the variation in the measured air intake pressure (ps) multiplied by a volume and temp...
