Other programs in the group calculate valve spring forces and valve train inertia throughout the range, and cam and lifter stress. The main program is for the design of the profile. A smaller program will generate plots from a lift table. At one type I worked with Harvey Crane and used his program The lift table from the cam profile design data is used to whittle out the model. The cam profile model is then put into the camshaft grinding machine and the master is made in the same way as if you were copying another camshaft. This was the best method available before CNC cam grinders came along Here's how Analytix Cams is used to synthesize a cam profile. First, you choose the cam/follower type and such things as direction of rotation and follower offset. and the desired curve type (such as cycloidal, dwell, or constant acceleration). Analytix/Cams then automatically synthesizes the precise points in between, taking into account all th

To get the data (i.e. follower motion) as well as draw the cam profile you can follow one of these. The design of fuel supply cam profile is one of the key techniques in the development of the fuel supply system. The fuel supply cam and the diameter of plunger codetermine the available injection duration, injection pressure, injection quantity and the highest working speed When designing a cam profile for an internal combustion engine, it is desirable to make the valve lift area be as large as possible and the valve peak acceleration and seating velocity be as low as those can be within the cam-event angle. But, as we know, those features conflict with one another Cam Profile The cam profile is the actual shape of the camshaft lobe. 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 A symmetrical lobe profile is faster and easier to develop, but it's a lazy way of designing a cam, says one engineer. However, another cam engineer tells us exactly the opposite; that he prefers symmetrical lobe profiles because they are easier on the valvetrain and springs

To allow more airflow into your engine, a camshaft is designed with a profile (or curve) that provides a specific amount lift to the valve. So in this issue, we're going to do some heavy bench racing and delve into camshaft basics cam lobe. Without owning the original design profile data, there can never be any quality control after grinding, as there is nothing available to quantify the finished cam to. This is a real problem for the grinder when checking the Jerk or 3rd derivative of the production cam, as Jerk can get very large in all the wron

Our cam profile designers currently use various methods of curve creation including the latest Concept Valve Train software licensed from Lotus Engineering. This enables us to quickly analyse potential vulnerabilities within existing valve train/cam profile and thereby solve potential reliability issues The cam lobes, one for each valve, contain all the variables.
