A lifter is a cylindrical component that rides on the Cam Shaft to actuate the Intake and Exhaust Valves. For pushrod engines, the Lifter pushes the pushrod up into the Rocker ArmRocker armA rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it.en.wikipedia.org and opens the valve. For OHC (overhead cam) engines, the lifter pushes directly on the valve tip.
How do lifters work on an engine?
There are a variety of lifter designs found in different types of engines. As the camshaft rotates, the lifters act on a series of pushrods, which, in turn, operate the rocker arms to open and close the engine’s valves. The lifters also maintain the engine’s valvetrain lash (clearance).
What are the different types of lifters on a motorcycle?
What’s more, there are flat lifters (tappets) and roller lifters. Flat lifters, which are typically found in vintage vehicles, have a relatively flat face that slides on the camshaft. Meanwhile, roller lifters have a wheel-like roller that follows the camshaft’s outline. Since the 1990’s, nearly all OHV engines have come with roller lifters.
What is a a lifter?
A lifter is a cylinder that sits between a car’s camshaft and the cylinder valves. As the camshaft moves over the top of the lifter, it actuates, temporarily opening the valve. And because the intake and exhaust valve need to open at different times, each has its own separate lifter. Lifters can be designed differently, depending on the vehicle.
Does an OHC engine have a lifter?
With “overhead cam” (OHC) engines, the camshafts are in the cylinder head (s) and actuate the valves directly or via cam followers, so there are no lifters. However, most modern OHC engines do have some type of hydraulic valve lash adjusters.
