An engine is provided to facilitate installation of a compressor on an engine. The engine can include a crankshaft, a front end, and an installation structure, and can be disposed in an engine compartment having an opening for accessing the engine. The installation structure can comprise an installation mount that can be disposed at the front end of the engine. The installation mount can extend substantially parallel to the crankshaft of the engine. The installation mount can include a surface configured for mounting the compressor. Further, the installation mount can be configured with the surface thereof facing toward the opening of the engine compartment. Additionally, the installation structure can be configured to facilitate meshing engagement of the crankshaft with a drive shaft of the compressor.
