Abstract
An engine apparatus includes an exhaust gas purifier configured to purify exhaust gas from an engine. The exhaust gas purifier is mounted on the engine with a longitudinal direction of the exhaust gas purifier being orthogonal to an output shaft of the engine. A cooling fan is disposed on one side surface of the engine that intersects the output shaft. The exhaust gas purifier is supported by a cylinder head at a portion on an upper surface of the engine that is closer to the cooling fan.
Claims7
An engine apparatus comprising:
- an engine having an intake manifold, an exhaust manifold, a cylinder head having a head cover, and an output shaft;
- a cooling fan disposed on a front surface of the engine that intersects the output shaft;
- a power generator;
- an EGR device;
- a coolant pump;
- an inlet-side bracket body and an outlet-side bracket body;
