    摘要： A method for controlling an engine comprises establishing a torque correction coefficient (KA) to compensate for reducing effect of available engine torque in operating range of different excess air ratios (null) that are lower than a predetermined value (unitynull1). An initial base desired in-cylinder air mass (tQacb) is determined based on a requested engine torque (tTe). A desired excess air ratio (tnull) is determined. The initial base desired in-cylinder air mass (tQacb) is adjusted with at least the desired excess air ratio (tnull) and the correction coefficient (KA) to generate a desired in-cylinder air mass (tQac). A desired injected fuel mass (tQf) is controlled based on the desired in-cylinder air mass (tQac) to deliver the requested engine torque (tTe) with the desired excess air ratio (tnull) held accomplished.

    摘要： A method and an arrangement for operating and monitoring an internal combustion engine are suggested wherein, in at least one operating state, operation is undertaken with a lean air/fuel ratio. At least one quantity, which represents the degree of actuation of the accelerator pedal, and a quantity, which represents the engine rpm, are detected and, in at least one operating state, only an operation of the engine with an approximately stoichiometric or rich mixture is permitted and/or only an operation with limited air supply is permitted. The operation is monitored on the basis of at least one operating variable of the engine.

    摘要： A fuel supply device comprising auxiliary throttle means located in the intake pipe upstream of an operator actuatable throttle means and a source of pressurized fuel comprising a delivery circuit which opens into a portion of the intake pipe downstream of the main throttle means, the delivery circuit being controlled by at least one solenoid valve. A metering system, which is sensitive to the degree of opening of the auxiliary throttle means, has means supplying repeating pulse signals. The metering system supplies the solenoid valve with one energization signal per pulse signal repetition period which has a duration equal to a fraction of the period which is adjusted by the metering system. The source of fuel has a pressure regulator comprising a relief valve which is biased toward opening by the fuel delivery pressure and toward closure by the vacuum in a chamber connected to the intake pipe. The chamber is bounded by a diaphragm, to which the closure member of the valve is connected. The duct connecting the chamber to the intake pipe communicates with the atmosphere via a second solenoid valve associated with an energizing electric circuit constructed to supply the second solenoid valve with repetitive excitation signals having a duration which varies in dependence on an engine operating parameter.
