Engine apparatus

摘要

An object in mounting an exhaust gas purifier to an engine as a component of the engine is to prevent a plurality of detection members, which are configured to detect a state of the exhaust gas purifier, from being disadvantageously affected by the heat of the engine and the exhaust gas purifier. An engine apparatus includes the exhaust gas purifier configured to purify exhaust gas from the engine. The exhaust gas purifier is mounted above the engine through a mounting base. A heat conductive bracket is disposed on an outer surface of the exhaust gas purifier that is closer to the engine. The plurality of detection members, which are configured to detect of the state of the exhaust gas purifier, are attached to an upper surface and a side surface of the heat conductive bracket.

1. An engine apparatus, comprising:
an exhaust gas purifier configured to purify exhaust gas from an engine and mounted above the engine through a mounting base, wherein an L-shaped heat conductive bracket is disposed on an outer surface of the exhaust gas purifier that is closer to the engine, a sensor fastening portion is integrally formed on a portion of a flange disposed on the exhaust gas purifier, the heat conductive bracket being detachably attached to the sensor fastening portion, on a horizontal plate portion of an upper surface of the heat conductive bracket is affixed an exhaust pressure sensor for detecting pressure of the exhaust gas of the exhaust gas purifier, on a vertical plate portion on a side surface of the heat conductive bracket is affixed an exhaust gas temperature sensor that detects temperature of the exhaust gas of the exhaust gas purifier, and on the heat conductive bracket, each of the horizontal plate portion, the vertical plate portion, and the sensor fastening portion have fastening surfaces oriented in differing directions relative to each other.
