Abstract
An engine includes an engine body assembly and an air intake system including an air plenum. The air plenum is positioned above the engine body assembly. The engine includes an air plenum support bracket having an upper arm coupled to the air plenum and a lower arm coupled to the engine body assembly. The engine also includes a vibration isolator coupled to the air plenum support bracket and interposed between the air plenum and the engine body assembly, thereby inhibiting engine vibrations from transferring to the air plenum.
Claims13
An engine for a vehicle, the engine comprising:
- an engine body assembly including a cylinder head and a cylinder head cover, the cylinder head defining one or more bosses;
- an air intake system including an air plenum, the air plenum positioned above the engine body assembly;
- an air plenum support bracket having an upper arm coupled to the air plenum and a lower arm coupled to the one or more bosses defined by the cylinder head, thereby bypassing the cylinder head cover;
- and
- a vibration isolator coupled to the air plenum support bracket and interposed between the air plenum and the engine body assembly, thereby inhibiting engine vibrations from transferring to the air plenum.
An engine for a vehicle, the engine comprising:
- an engine body assembly;
- and
- an air intake system coupled to the engine body assembly, the air intake system comprising:
- an air plenum having a downstream portion defining an air discharge port;
- an air intake runner having an upstream end defining an air inlet port in fluid communication with the air discharge port of the air plenum;
- a bracket having an upstream end coupled to the downstream portion of the air plenum adjacent to the air discharge port and a downstream end coupled to the air inlet port defined by the upstream end of the air intake runner;
- and
- a vibration isolator coupled to the bracket and interposed between the air plenum and the air intake runner, the vibration isolator inhibiting engine vibrations from transferring to the air plenum.
