An engine system includes: a reformer including a catalyst for decomposing fuel into hydrogen and configured to reform the fuel to generate a reformed gas containing the hydrogen; a temperature detection unit configured to detect a temperature of the reformed gas; a rotation fluctuation detection unit configured to detect an amount of rotation fluctuation of an engine; and a deterioration detection unit configured to detect whether reforming performance of the catalyst of the reformer is deteriorated based on detection values of the temperature detection unit and the rotation fluctuation detection unit, wherein when, in an idling period of the engine, the amount of rotation fluctuation of the engine is equal to or greater than a second threshold in a state where the temperature of the reformed gas is equal to or higher than a first threshold, the deterioration detection unit determines that the reforming performance of the catalyst is deteriorated.

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

A power system comprises an engine configured to combust an air/fuel mixture and produce a flow of exhaust gas; an exhaust passageway fluidly connected to the engine to receive the flow of exhaust gas; an exhaust gas recirculation loop fluidly connecting the exhaust passageway to a fuel intake for the engine; a first conversion zone containing a fuel reforming catalyst located within the exhaust gas recirculation loop; and a second conversion zone located within the exhaust gas recirculation loop separate from and downstream of the first conversion zone stream, the second conversion zone containing a fuel cracking catalyst.

In a spark ignition engine, a thermal insulation thin layer is formed over a wall surface, facing an inside of a combustion chamber, of a base material forming the combustion chamber, and for a thermal conductivity &#x3bb; [W/(m&#xb7;K)], a thermal diffusivity &#x3ba; [mm/s], and a thickness L [&#x3bc;m] of the thermal insulation thin layer, L&#x2267;16.7&#xd7;&#x3bb; and L&#x2266;207.4&#xd7;(&#x3ba;)are satisfied. With such a configuration, a heat loss Q_total escaping from gas in a cylinder to the wall of the combustion chamber over all strokes can be reduced, and the thermal efficiency can be improved without inducing degradation of knocking due to an increase in an amount of heating Q_intake of the gas in the cylinder during an intake stroke.

Spark ignition type internal combustion engine

An exhaust gas control apparatus includes a control device controlling a urea addition valve for adding urea from an upstream side of a NOx reduction catalyst. The control device obtains an ammonia adsorption amount distribution through the NOx reduction catalyst. When an ammonia adsorption amount in a predetermined part on a downstream side equals or exceeds a predetermined threshold, the control device controls the urea addition valve to stop the urea supply or reduce the amount thereof. The urea addition valve is controlled based on an adsorption amount distribution obtained from a model on which the catalyst is divided into cells such that an ammonia adsorption amount in a first cell positioned furthest upstream equals or exceeds a predetermined threshold close to a saturation adsorption amount and an ammonia adsorption amount in a second cell positioned downstream of the first cell reaches a predetermined target value smaller than the threshold.
