Efficient Performance

Internal combustion engine (ICE)
finds its place in the market with latest design
modifications in various components to
improve efficiency, economy and overall
performance. However, one component has
remained unchanged in the internal
combustion engine development i.e., the
camshaft which has been the primary means of
controlling the valve actuation and timing, and
therefore, influencing the overall performance
of the vehicle. The camshaft is attached to the
crankshaft of an ICE and rotates relative to the
rotation of the crankshaft. Therefore, as the
vehicle increases is velocity, the crankshaft
must turn more quickly, and ultimately the
camshaft rotates faster. This dependence on
the rotational velocity of the crankshaft
provides the primary limitation on the use of
camshafts. Camless technology is capturing
the future of internal combustion engines. It
has been known to man that if valves could be
controlled independently in an Internal
Combustion Engine then there would be
benefits like increased power, reduced
emissions and increased fuel economy. In the
camless technology valve motion is controlled
directly by valve actuator- there `s no camshaft
or connecting mechanism .Precise electronic
circuit controls the operation of the
mechanism, thus bringing in more flexibility
and accuracy in opening and closing the
