cam lobe

The main body of the cam lobe is in its maximum duration form.

Do not remove the black phosphate coating from cam lobes.

The cam lobes are placed in two rows for the intake and exhaust.

Flank: The side of the cam lobe that lies between the nose and the base circle.

The slot in fact replaces the closing flank on the main body of the cam lobe.

The radial engine normally uses fewer cam lobes than other types.

Cam lobes are ground to ensure perfect timing.

This system consists of a cam lobe that varies along its length (similar to a cone shape).

This design allows for variable valve timing as well, since the cam lobe profiles can be made different.

Other components such as cam lobes and cylinder walls are lubricated by oil jets.

When dismantled the cam lobes appeared to have about 0.002" lipping on the front edges.

The two intake valves in each cylinder are operated by a rocker arm with its own cam lobe.

Before we can measure a cam lobe we must address the issue of how to mount the camshaft for measuring.

Naturally, I'm looking for power and I'm not above alittle cam lobe work either.

Later 24 valve VR6 engines still had two overhead camshafts, but with 12 cam lobes each.

The cam lobes activated the valves directly via a bucket over shim arrangement.

By shifting area of the cam lobe which is in contact with the follower, the lift and duration can be continuously altered.

Some manufacturers use systems with more than one cam lobe, but this is still a compromise as only a few profiles can be in operation at once.

They also made alterations by drilling holes in the cam lobes and capping off the hollow cam's ends.

The VTEC system consists of two separate cam lobe profiles.

The cam lobes force the valves open by pressing on the valve, or on some intermediate mechanism as they rotate.

Here we retain the same 1/2 stage improvement in the primary cam lobes, but go to a larger grind on the secondary lobes.

The mechanism is a coaxial shaft arrangement where the outer shaft carries the main body of the cam lobe.

Nose of Cam: The highest point of the cam lobe and often the area where most wear occurs.

This allows each lifter and pushrod to deflect from the cam lobes perpendicular to the lobe plane.
