We could help this situation by using
a different cam profile which allows the cam to be open for longer.
3 - Stage VTEC is a version that employs three
different cam profiles to control intake valve timing and lift.
The Cam Profile Switching (CPS) system uses a tri-lobe camshaft to switch between two
different cam profiles.

Most cars nowadays have some sort of variable
cam that allows
different profiles for low and high RPM.
This design allows for variable valve timing as well, since the
cam lobe
profiles can be made
different.
Among
different cam - based VVA systems,
cam - phasers and
cam -
profile — switchers (CPS) are two well - known technologies.
Gen V
Cams feature four
different lobe
profiles to both create AFM compatibility and optimize intake and exhaust valve opening / closing events.
As the engine load changes, electromagnetic actuators allow a movable shaft containing
different cam lobes to shift imperceptibly between high - lift and low - lift
profiles.
