摘要： The mean oxygen richness (S0) of the exhaust gases is measured during a first engine operating phase during which the device for injection of air (2, 5, 6) is active and the mean oxygen richness (S1) of the air/exhaust gases mixture is measured during a second consecutive phase during which this device (2, 5, 6) is inactive and the operating condition of the device is diagnosed (2, 5, 6) by comparing the difference (S0-S1) in the oxygen richnesses measured during these two phases, with an expected value of this difference. Application to an engine (M) equipped with a catalytic chamber (8) for oxidation-reduction of the exhaust gases.

摘要： A heated catalytic converter (1) is arranged upstream from a trifunctional catalytic converter (2) in an exhaust gas outlet (3). A computer (7) includes a unit for the closed loop control of the air/fuel mixture supplied to the engine, and a unit for performing the method for monitoring the efficiency of a trifunctional converter (2) as disclosed in French patent application No. 91-13237. When cold starting the engine, the closed loop mixture control unit is activated when the temperature of the heated converter exceeds a predetermined temperature (Ts), and any oscillation occurring in the probe output indicates that the heated catalytic converter is not efficient enough.

摘要： The mechanical power supplied by an engine (1) to an auxiliary apparatus (23) is reduced during a cold starting phase of the engine with respect to the power normally absorbed by the normally operating apparatus. When the apparatus is an alternator, a reduction in the power supplied by the engine, and a resulting drop in pollution, may be achieved by reducing the alternator exciting current (I) under the control of a computational unit (11).

摘要： A method for diagnosing a fuel vapour recovery system using a pump (10) with a membrane (11) particularly including means (12) for generating a signal indicating a predetermined position of the membrane, and a system venting valve (15) that is normally open when the pump is inoperative and closed when it is operative. According to the method, the operation of the valve is diagnosed by comparing a first time (TM1) taken by the membrane to return to the predetermined position after a first series of pumping cycles with a second time (TM2; TM2') taken by the membrane to return to the predetermined position after a second pumping cycle once the pump has been inoperative for a predetermined time (TA).

摘要： According to the invention, a set-point position ( alpha c) is calculated continuously for an event concerning the valve. Upon detection of a change of the set-point ( alpha c) or the engine rotation speed (N), (a) the setting of the new set-point is controlled in open loop at least during the first engine cycle following the set-point change detection and (b) the taking-up of the new set-point is then controlled in closed loop during the following engine cycles. The control is applied to an event triggering means with an avance (AV) with respect to the event. At each open loop control cycle, said advance is read in a stored table, as a function of the engine rotation speed (N) and of the set-point position ( alpha c) calculated for the event. Application to the control of the variable opening and closing of an intake valve.
