Abstract (en)
[origin: EP0646712A1] The system comprises sensors (3) which detect parameters of the engine; an electronic injection device (4) a block which controls the injection device in normal fuel-air mixture-delivery conditions; means (23) which compare for each engine phase the value (F) of the position of the air induction manifold butterfly valve with a first threshold value (MF1); means (24) which for each engine phase, compare the value (RPM) of the engine speed with a second threshold value (MRPM1); and means (25), activated if the value of the butterfly position is less than the first threshold value and the value of the engine speed is greater than the second threshold value to control, for each cylinder of the engine and according to a table (28) the rate of flow of fuel-air mixture so as to change from normal fuel-delivery conditions to a fuel mixture cut-off condition with a predetermined law of variation of engine torque. <IMAGE>
