    摘要: The vehicle and the power unit include: an engine; and a control apparatus that controls combustion of the engine, in which a bore diameter of the engine is 45 mm to 60 mm, and the control apparatus includes a knock sensor that detects vibration of the engine. The control apparatus extracts, from a detection signal of the knock sensor, components in a primary frequency band that is a lowest frequency band among a plurality of frequency bands in which peaks of knocking vibration are distributed according to the bore diameter of 45 mm to 60 mm, with a larger gain than that of components in a secondary frequency band that is a second lowest frequency band. The control apparatus determines that knocking occurs based on a detection signal in which the components in the primary frequency band are extracted with a larger gain than that of the components in the secondary frequency band, and controls the combustion of the engine based on a determination result of the occurrence of knocking.

    摘要: A method for the interpretive identification of a premature ignition in a combustion chamber of an internal combustion engine, wherein a feature (14, 16) which characterizes a combustion in the combustion chamber is determined and, on the basis of a parameter, a distinction is made between a normal combustion and a premature ignition by virtue of a threshold value (24) for the parameter being defined, which threshold value separates a first parameter range (18), assigned to a normal combustion, from a second parameter range (20), assigned to a premature ignition, and it is determined whether a value, assigned to the determined feature (14, 16), of the parameter lies in the first parameter range (18) or in the second parameter range (20), is characterized in that an adaptation for the threshold value (24) is performed by virtue of the interval between a value, assigned to a feature (14), of the parameter, which value lies in the first parameter range, and the threshold value (24) being determined, and an adaptation value (22) for the threshold value (24) being derived from said interval.

    摘要: The invention relates to a method for processing a signal of a pressure measuring device inside an internal combustion engine, said device comprising: a pressure measuring sensor outputting a voltage signal (S
    B ); and a processing unit connected to said pressure measuring sensor. According to the invention, the method comprises the following steps: I. calculation of a duration (Dt1) between a first instant (t0) corresponding to a first combustion peak pressure (P0) and a second instant (t1) corresponding to a second combustion peak pressure (P1), following the first combustion peak pressure (P0); II. calculation of a correction initiation instant (t
    c1 ) defined according to the previously calculated duration (Dt1); III. measurement of a value of the signal (V
    OFF1 ) at the time of the correction initiation instant (t
    c1 ); and IV. correction of the signal, from the correction initiation instant (t
    c1 ), in relation to a reference value (V
    REF ), and generation of a first processed signal (S) such as
    S = S B — V OFF1 + V REF.
