Abstract

PURPOSE:To make the driver feel no shock due to alternation of working cylinders by making a cylinder group, different from a cylinder group which operated partial cylinders operation before starting all cylinders operation, operate partial cylinders operation when an engine shifts from all cylinders operation. CONSTITUTION:An engine is shifted from all cylinders operation, in which fuel is injected from injection valves 9 of all cylinders 1-6 based on output signals from an engine speed sensor 28 and a throttle sensor 14, to partial cylinders operation according to operating condition. In this case, discriminating cylinder group which operated partial cylinders operation before starting all cylinders operation, an electronic control unit 20 outputs signal, namely when they are cylinder group 1-3, the same outputs fuel cut off signal for fuel injection valves 9 of them, and when they are cylinder group 4-6, the same outputs fuel cut off signal for fuel injection valves 9 of them. Thereby, alternation of shifted cylinders and rested cylinders is performed in the time of starting partial cylinders operation, therefore the driver does not have uncomfortable feeling owing to shock at the time of cylinder alternation.
