    摘要： The invention relates to a hardware architecture of a system (1) for driving injection in internal combustion engines (2), of the type intended to cooperate with an engine electronic control unit (ECU) by driving corresponding injection drivers (3). The system (1) comprises:

    a first I/O interface module (4) embedding a plurality of registers and receiving signals from said engine ECU;
    a second module (5) bi-directionally connected to the first module (4) from which it receives information at least on the injection times and the quantity of fuel to be injected for generating driving signals for said injection drivers (3), thereby actuating a desired injection profile;
    a third module (6) capable of emitting an interrupt signal toward said control unit (ECU) on the basis of signals received by said second module (5).

    摘要： The invention relates to a method for the open-loop control and the closed-loop control of an internal combustion engine (1), the rail pressure (pCR) being controlled in the normal operating state in a closed loop control mode via an intake throttle (4) on the lower pressure side as the first pressure control member in a rail pressure control loop and at the same time a rail pressure disturbance variable being applied to the rail pressure (pCR) via a pressure control valve (12) on the high pressure side as the second pressure control member. For this purpose, a pressure control valve volume flow (VDRV) is redirected from the rail (6) to a fuel tank (2) via the pressure control valve (12) on the high pressure side, and an emergency operation mode is activated once a defective rail pressure sensor (9) is detected, in which emergency operation the pressure control valve (12) on the high pressure side and the intake throttle (4) on the low pressure side are actuated depending on the same set point value.

    摘要： The invention relates to a method that consists of: a) determining a value representative of the temperature (Tavt) of the exhaust gases flowing in an exhaust duct of said engine upstream from the turbine of a turbocharger; b) comparing said value representative of said temperature with a predetermined threshold value (Tavt_seuil); c) if said representative value is higher than said predetermined threshold value, initiating the timing-out of a first time delay (tempo_in) during which steps a) and b) are repeated and, if during the timing-out of the first time delay, a value representative of said temperature is determined to be lower than said predetermined threshold value, suspending the timing-out of said first time delay and proceeding with step d); d) if said representative value is lower than said predetermined threshold value, initiating the timing-out of a second time delay (Tempo_out) during which steps a) and b) are repeated and, if during the timing-out of said second timing-out, a value representative of said temperature is determined to be higher than the predetermined threshold value, suspending the timing-out of said second time delay, resetting the measure of the timing-out of said second time delay, and proceeding with step c); e) if the first time delay has elapsed and said representative value is higher than said predetermined threshold value, preventing the automatic stoppage of the engine; f) if the second time delay has elapsed and said representative value is lower than said predetermined threshold value, authorising the automatic stoppage of the engine and resetting the measure of the timing-out of the first time delay.
