Abstract
The EGR controller,controls the EGR actions wherein exhaust gas from the cylinder cut-off engine,which can change over the running condition between the all-cylinder run and the cut-off-cylinder is recirculated to the induction. The EGR controller,comprises an EGR control valve,for opening and closing the EGR pipe,, a water temperature sensor,for detecting cooling water temperature TW and an ECU,, and the ECU,controls the EGR actions so as tobe executed if the cooling water temperature TW is higher (determined as “Yes” at Step,) than the upper limit value TWE1H while at the all-cylinder run (determined as “No” at Step,) or if the cooling water temperature TW is higher than the lower limit value TWE1L while at the cut-off-cylinder run (determined as “Yes” at Step,).
