    Abstract: A method for operating an internal combustion engine of a motor vehicle having a plurality of cylinders all of which are operated in a full load engine mode and some of which are shut down in a partial load engine mode is disclosed, wherein the full load engine mode is switched to the partial load engine mode only if a partial engine operating torque which can be provided by the internal combustion engine in the partial load engine mode is greater than or equal to a target torque set on the internal combustion engine. In order to switch from the full load engine mode to the partial load engine mode, a switch variable determined on the basis of at least one specific parameter of the internal combustion engine and/or of the motor vehicle must additionally be set.

    Abstract: Method and systems are provided for adjusting an engine torque in response to changes in a desired engine torque. In one example, a method may comprise responsive to increasing desired engine torques, monotonically decreasing an alternator torque to a first level from a second level when not injecting fuel to engine cylinders, and stepping up the alternator torque from the first level to the second level while initiating engine combustion, and then monotonically decreasing the alternator torque from the second level to the first level in response to the alternator torque reaching the first level. In this way, a method may comprise adjusting a load exerted on an engine by an alternator mechanically coupled to said engine during both cylinder combustion, and during non-fueling conditions.

    Abstract: A method for regulating the power delivered by a reciprocating engine includes the definition of the value of a constant time interval T1 and the values of a threshold for the engine rpm and of a threshold for the percentage opening of the engine throttle valve, below which an operating area is defined in the Cartesian graph xy whose axes represent the engine rpm and the percentage opening of the throttle valve TPS. The method also includes: measuring, for each engine cycle, the value of the engine RPM at the level of an angular position of the crankshaft in a specific stroke (IS, PS); calculating, at the final instant (A) of each time interval T1, an activation value X* obtained from a comparison between the last RPM value measured before the final instant (A) and the last RPM value measured before the initial instant (B) of the time interval T1.

    Abstract: When a catalyst of an internal combustion engine is not activated, a control apparatus retards the ignition timing of a spark plug, and thereby, executes a rapid warm-up control of the catalyst. However, on this occasion, when alcohol concentration Ca is high, the control apparatus sets the ignition timing to a more advanced side than when the alcohol concentration Ca is low. When the ignition timing is set to an advanced side, opening angle θ of a throttle valve is manipulated such that command value qsjc for the quantity of the air that is filled into a combustion chamber is increased. Thereby, compared with when the command value qsjc is not increased, the quantity of the fuel that is injected from a cylinder injection valve increases, and the thermal energy of exhaust gas increases.

    Abstract: An ignition timing controlling apparatus for an engine includes an ignition timing map in which high-torque timings are stored, an ECU for changing a high-torque timing obtained from the ignition timing map into a fuel-conserving ignition timing, and an advance angle target amount map in which advance angle target amounts with which the high-torque timing is to be changed into the fuel-conserving ignition timing are stored. The ECU is operable to calculate an advance angle target amount for each of cylinders of the engine based on the advance angle target amount map when a running state of a vehicle is in a cruize state in which little acceleration or deceleration is included, and also to execute advance angle control of changing the ignition timing of each of the cylinders stepwise with respect to the advance angle target amount for each of the cylinders.
