The camshaft pattern refers how the profile of the intake and exhaust lobes compare to each other.

Camshaft lobe profile. Lobe Centerline Tailoring the valve opening and closing points on an actual camshaft is accomplished by varying the lobe centerline location changing the LDA and refining the profile shape. The camshaft profile refers to the shape of the individual lobes. COMP Cams Lobe Profile Catalog 2.

The rocker arm transfers the motion of the valve lifter riding on the cam lobe to the valve and increases the lobe lift by the amount of the rocker ratio which is typically 15 to 171. For example camshaft A has intake lobes of 260 degrees duration while the exhaust lobes are 270 degrees duration. They are arranged in groups each of which is unique in its application.

Turning at half the speed of the engines crankshaft the camshaft has a lobe for each valve that pushes up on each valve lifter in a particular sequence. It is measured in crankshaft degrees to make it easier to degree check the cam to make sure it is positioned properly in the engine. With thousands of active lobes in the COMP library the combinations are infinite for any given engine.

Cam Profile The cam profile is the actual shape of the camshaft lobe. Ramps are the parts of the lobe where the lifter is either moved up or. When comparing cam profiles its best to use the050 duration numbers.

That is the brief period of time when both the intake and. A smaller base circle allows more lobe lift but it can also allow the camshaft to flex and throw off the timing events. Selecting Lobes The lobes are listed on pages 6-56 and represents the most current library of lobes offered by COMP Cams.

An interactive camshaft calculator where engine builders can see how valve overlap and boost efficiency is affected by a camshafts physical design. Camshaft duration is the amount of crankshaft rotation that occurs as the cam lobe moves the lifter off of the base circle. We make durations at050 that range from 193 degrees to 282 degrees in one degree increments.

The lobe separation angle or LSA is the angle in camshaft degrees between the maximum lift points or centerlines of the intake and exhaust lobesThe lobe separation angle or LSA is the angle in camshaft degrees between the maximum lift points or centerlines of the intake and exhaust lobes. Lobe separation angles the angle in cam degrees between the intake and exhaust lobe are also referred to as lobe centers are very engine combi-a peakier torque curve more suited to stick-shift cars with multiple gear ratios to change between. Wider lobe separation ex.

In this tech article we explain the pros and cons of installing your cam straight up. The valve lifters through the push rod and rocker assembly open each valve in turn to either let intake gasses in or exhaust gases out. Likewise a really pointy cam lobe that produces a lot of valve lift can be hard on the lifters and valvetrain.

The lobe is at050 lift on the other side of the lobe. Camshaft B has intake and exhaust lobes that are both at 260 degrees. A flat tappet camshaft is slightly more pointed on the nose of the lobe while a roller lift camshaft has a more rounded profile on the nose of the lobe.

These lobes are available in wide range of lifts in005 lobe lift increments. An aggressive lobe profile that opens the valves quickly may make more power but it may also kill the life of the valve springs. A full cam profile can be automatically generated for you based on the opening and closing points or lobe center angles and duration and lift heights that you specify or you can enter your own measured or existing data.
