An engine system includes: a combustor including an ignition unit configured to ignite the fuel gas and configured to generate combustion gas that heats a catalyst; an outside air temperature detection unit configured to detect an outside air temperature; a catalyst temperature detection unit configured to detect a temperature of the catalyst; an operating environment detection unit configured to detect an operating environment of the combustor; a combustion time determination unit configured to determine combustion time of the combustor; and a start control unit configured to, at a time of starting the engine, perform ON control on a starter and the ignition unit and control a third fuel supply valve, a first flow rate control valve, and a second flow rate control valve to open, and thereafter when the combustion time elapses, perform OFF control on the ignition unit and control the third fuel supply valve to close.

Engine system

An exhaust gas purification apparatus includes: an oxidation reduction catalytic converter; a selective reduction catalytic converter disposed downstream of the oxidation reduction catalytic converter; and a controller configured to perform a first control or a second control based on mixing ratios when a temperature is higher than a predetermined temperature. The first control is performed when the mixing ratio downstream of the selective reduction catalytic converter is greater than the mixing ratio upstream of the selective reduction catalytic converter so that the mixing ratio upstream of the selective reduction catalytic converter is changed from stoichiometric ratio to lean mixture ratio. The second control is performed when the mixing ratio downstream of the selective reduction catalytic converter is smaller than the mixing ratio upstream of the selective reduction catalytic converter so that the mixing ratio downstream of the selective reduction catalytic converter is changed from stoichiometric ratio to lean mixture ratio.

Exhaust gas purification apparatus and exhaust gas purification method

An output power controlling apparatus and a method for reducing vibration caused by accelerating or shifting gearing in a vehicle includes a vibration component prediction section/step for predicting a vibration component to be generated on the vehicle from the target torque correlation value using a predetermined prediction model, and a feedback correction section/step for feedback correcting the target torque correlation value based on the predicted vibration component to suppress vibration.
