According to the invention, in case that the performance of the fuel supply stop control is inhibited when the catalyst temperature is higher than or equal to the performance inhibiting temperature, a temperature lower than a base temperature of the performance inhibiting temperature is set as the performance inhibiting temperature while the use degree of the catalyst is lower than or equal to a predetermined degree and in case that the performance of the fuel supply amount increase control is permitted when the catalyst temperature is higher than or equal to a performance permitting temperature, a temperature higher than a base temperature of the performance permitting temperature is set as the performance permitting temperature while the use degree of the catalyst is smaller than or equal to the predetermined degree..

Control apparatus for internal combustion engine
This control apparatus for an internal combustion engine includes: a turbo-supercharger; a port injection valve and an in-cylinder injection valve; and catalysts. The control apparatus determines whether or not blow-by of gas to an exhaust passage from an intake passage through a combustion chamber occurs, or whether or not a condition in which the blow-by of gas is likely to occur is satisfied.

Control device of internal combustion engine and method of controlling the same
In an internal combustion engine that is capable of performing a fuel supply cut control (fc control), a performance of the fc control is suspended, in a case where, when the performance of the fc control is requested to initiate, a deviation between a solid solution of an active element in a carrier and a target solid solution is equal to or more than a predetermined upper limit value and a catalyst temperature is equal to or more than a predetermined upper limit temperature.. .

Low temperature catalyst light-off
A catalyst associated with an internal combustion engine can be heated to improve emissions performance of the engine. Hydrogen can be generated within the internal combustion engine by combusting a first combustion mixture having a first air-fuel ratio including excess fuel relative to a stoichiometric air-fuel ratio, such that a reforming reaction occurs during the combusting of the first combustion mixture.

Direct injection of diluents or secondary fuels in gaseous fuel engines
A method for a turbocharged engine, comprising: during high load conditions, in response to an elevated engine temperature, after port injecting a first quantity of a first gaseous fuel, direct injecting a second quantity of a second, liquid fuel at a first timing that is a function of a desired air-fuel ratio. In this way, engine power may be maximized while simultaneously decreasing the maximum combustion temperature and mitigating engine knock..
