In this method a generic geometric model of the cam profile
is defined, and the corresponding equations of the circular arcs are derived using a homogeneous coordinate transformation approach.
This second iteration cam profile
and associated EGR control strategy was not installed into the truck for testing, but dyno results from this setup are included in this paper.
The X15 cam profile
minimizse inherent parasitic loss during combustion, in essence breathing easier, and thus increases thermal efficiency.
The exhaust cam profile
is slightly modified from the existing Cam.
Further, the intake cam profile
has been changed, the diameter of the throttle body increased from 76 to 83 mm, and both the intake and exhaust valves are made from titanium.
Since the cam profile
curve directly determine the kinematics and dynamics characteristics of the mechanism, designing appropriate cam profile
curve caused the wide attention of scholars.
The air intake throttle valve and EGR valve are connected through a highly flexible coupling (cam-link mechanism), allowing the new unit to be applied to various engine parameters, including displacement and output, merely by changing the shape of the connection between the two valves (cam profile
Therefore, the (x, y) coordinates of the points on the cam profile
curve can be written as
It is also different from the CAM profile
, which suggests that our stochastic NN convection parameterization effectively introduces in the CAM-NN run the convection and cloud physics, which is different from that of introduced in the parallel CAM run employing an existing CAM convection parameterization.
The rocket-fast RKT cam automatically adjusts the cam profile
to achieve the smoothest draw imaginable.
