摘要： PROBLEM TO BE SOLVED: To realize the efficient and stable operation of an internal combustion engine by solving problems in accompany with the introduction of various controls to improve the practical fuel consumption and the exhaust gas performance in an internal combustion engine.
SOLUTION: This controller for the internal combustion engine can switch a multicylinder engine 1 between full cylinder operation and partial cylinder operation, and the torque shock is prevented by retarding an ignition period in a transition period of the switching. The exhaust gas performance can be improved by introducing EGR into the engine 1, and the introduction of EGR is forbidden by closing an EGR valve 26 in switching the operation. Whereby the instable combustion can be surely prevented in switching the operation, even when the EGR is applied in the engine 1.

摘要： PROBLEM TO BE SOLVED: To provide a failure diagnosing device capable of surely determining the micro leakage, and the abnormality caused by the micro leakage in a system for preventing transpiration of evaporated fuel.
SOLUTION: In a case when a first pressure recovery amount (ΔP) measured after depressurizing a failure diagnosis area, is over a first or second determination value (L11, L12), a second pressure recovery amount (reΔP) is measured after the failure diagnosis area is opened to the atmospheric air, and then sealed. The second pressure recovery amount is compared with a third determination value (L21), when the first pressure recovery amount is between the first determination value and the second determination value, on the other hand, when the first pressure recovery amount is over the second determination value, the second pressure recovery amount is compared with a fourth determination value (L22). When the first pressure recovery amount is over the first determination value, and the second pressure recovery amount is not over the third determination value, or when the first pressure recovery amount is over the second determination value, and the second pressure recovering amount is not over the fourth determination value, the leakage is determined.
