How does pushrod engine work

Advantages of Pushrod engines: One of the main advantages of a Pushrod engine is its compactness. The Pushrods connected to the Camshaft lie in the free space present between cylinder banks. This saves up space while designing an engine and also gives designer lots of room to improve on other aspects of the bike, for example, its height.

Many high performance engine builders prefer one-piece push rods rather than three-piece push rods that have welded roller balls.

Roller balls on one-piece push rods are machined to conform to the recessed cups in a rocker arm. This type of push rod is more expensive. However, the welded roller ball on the end of a three-piece push rod is vulnerable to breaking off in racing conditions. Hydraulic lifters are used in conjunction with push rods to operate the engine valves.

Push rods for this type of system have a roller ball that contacts the cam lobe and a tapered end that fits into a hydraulic unit. The hydraulic unit performs the same function as a mechanical rocker arm.

The application of hydraulic lifters is not confined to racing or touring car engines. Debates surrounding the benefits and drawbacks of hydraulic lifters remain ongoing. I agree to receive emails from Motor Authority. I understand that I can unsubscribe at any time.
