摘要： An engine includes variable valve mechanisms and a variable compression ratio mechanism. An ECU executes temperature balance control when a fuel-cut operation is executed. In the temperature balance control, valve opening characteristics of an exhaust valve are controlled based on a magnitude relation between an actual catalyst temperature and a target catalyst temperature and a magnitude relation between a water temperature and a required cylinder wall temperature. When executing a fuel-cut operation, it is thereby possible to control both the actual catalyst temperature and the water temperature in a well-balanced manner so that the actual catalyst temperature falls within a temperature range suitable for operation of the catalysts, and the water temperature becomes close to the required cylinder wall temperature.

摘要： It is an object of this invention to restrain blow-by gas from reaching a catalyst during fuel cutoff, and protect the catalyst while coping with an increase in oil dilution amount resulting from the use of alcohol fuel, in an internal combustion engine that uses the alcohol fuel. An engine is equipped with a PCV mechanism that introduces blow-by gas in a crankcase into an intake system. Besides, when fuel cutoff is executed with the PCV mechanism in operation, an opening degree of a throttle valve during fuel cutoff is set on the basis of an oil dilution amount in lubricating oil. Thus, the throttle opening degree during fuel cutoff is adjusted in accordance with a generation amount of blow-by gas, so that an intake negative pressure can be appropriately reduced. Accordingly, during fuel cutoff, the amount of blow-by gas that is sucked out from the crankcase due to the intake negative pressure and introduced into the intake system can be held small.

摘要： When alcohol-blended fuel is supplied to an internal-combustion engine, the magnitude of alcohol concentration (more particularly, ethanol concentration Cetha) is judged (Step 1005) and, based on this judgment, the magnitude of operational status temperature (more particularly, cooling water temperature THW) is judged (Step 1015). Then, when the alcohol concentration is large and the operational status temperature is low, generation of an intermediate product which is an oxide of alcohol contained in the alcohol-blended fuel in an unburnt state after main injection and alcohol contained in the alcohol-blended fuel in an unburnt state after post injection (more particularly, aldehyde) is promoted, and the generated intermediate product is trapped in an intake passage by making an intake valve into an opened state in an exhaust stroke of the internal-combustion engine (Step 1055).

摘要： In an FFV (flexible fuel vehicle) on which an internal-combustion engine using alcohol blended fuel in mounted, the remaining amount of fuel vapor presumed to remain in a canister in accordance with a usual purge processing is presumed based on an alcohol concentration in the alcohol blended fuel. According to this remaining amount, the size of the tank side channel which is a channel in a canister near the connection section with a connection pathway (tank line) with a fuel tank is adjusted by a canister throttle control means, and/or, the timing of opening and closing of an intake valve is changed by a variable valve timing mechanism. Thereby, the desorption rate (the amount of desorption) of fuel vapor from adsorption material in a canister is adjusted, and the concentration of the fuel included in purge gas is adjusted. As a result, even when the change of the remaining amount of the fuel vapor adsorbed by the adsorption material in the canister and/or the uneven concentration distribution of an alcohol component within the canister occur, the accuracy of an air/fuel ratio control in the FFV can be raised, and the discharge of a toxic substance can be suppressed effectively.
