Answer :
Final answer:
The component that is NOT located on an overhead cam engine is pushrods, as they are used in OHV engines. Lifters and rocker arms are present in OHC engines, along with timing chains. Pushrods are specifically associated with different engine configurations.
Explanation:
Understanding Overhead Cam Engines
An overhead cam (OHC) engine features a configuration where the camshaft is positioned above the cylinder head. This design offers various advantages over traditional configurations, including improved efficiency and engine performance. To determine which component is NOT typically found in an OHC engine, let’s review the options:
- Lifters: These are found in both OHC and other engine types to operate the valves.
- Rocker arms: Also present in OHC engines, they pivot to open and close valves.
- Pushrods: These are used in overhead valve (OHV) engines, where the camshaft is located in the block and requires pushrods to actuate the rocker arms. Thus, this is the correct answer.
- Timing chains: Used to synchronize the camshaft with the crankshaft, these are indeed found in OHC designs.
Therefore, the correct answer is Pushrods, as they are not part of an overhead cam engine.
