Abstract: 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.

Abstract: To provide a simple blower which can suppress the infiltration of a target gas into a shaft hole and having a small size and cost reduction, a blower comprising a first casing (11) formed with a gas passage (11c) for introducing a high temperature gas and a shaft hole (11e) for communicating therewith, a rotating shaft (14) inserted to be freely rotatable within the shaft hole (11e), an impeller (13) housed within the first casing (11) which integrally rotates with the rotating shaft (14), a motor (15) for driving the rotating shaft (14) from the rear end side, a second casing (12) having an interior space (21) which communicates with the shaft hole (11e) and supporting the rotating shaft (14) via bearing (22A, 22B), and a purge gas introduction means (16) which introduces to the interior space (21), a purge gas having a higher pressure than a pressure of the shaft hole (11e), wherein the inflow of an exhaust gas into the shaft hole (11e) from the gas passage (11c) side of the first casing (11) is suppressed
