An ignition device for an internal combustion engine (1) includes a superpose voltage generation circuit (47) that, after the initiation of a discharge with the application of a discharge voltage by a secondary coil, applies a superpose voltage between ele...

In a method for controlling operation of an engine (10) according to the present invention, which an EGR system (36) is incorporated therein, when the engine is in a pressure-accumulable operational state in which EGR gas can be pressure-accumulated in an ...

Provided is an exhaust gas recirculation apparatus of an internal combustion engine which can effectively suppress condensed water from being generated in an EGR passage, compared with the conventional apparatus. The exhaust gas recirculation apparatus inc...

A method for controlling combustion in a multi-cylinder engine includes injecting fuel into at least one cylinder of the multi-cylinder engine and, for each cylinder, separately controlling at least one fuel injection parameter to produce a desired exhaust...

An exhaust emission control device for an internal combustion engine is provided that can suppress the adherence of HC to an EGR path and the like accompanying enrichment of the exhaust air/fuel ratio. The exhaust emission control device includes: a high-p...

A control system for an internal combustion engine (3), which reduces the frequency of operation of an EGR bypass valve (17), thereby making it possible to prolong a service life of the EGR bypass valve (17) and reduce the power consumption of a negative p...

A turbo-charged diesel engine is provided with a "long route" exhaust-gas recirculation pipe (18), which branches off from a main exhaust pipe (14), downstream of the turbine (15) of the turbosupercharger assembly (9, 15), and converges in a main intake pi...
