Electric Camshaft Phasing System to Meet Euro 6/BS-VI Emission Norms for Gasoline Engine 2019-26-0055
In today's ever changing scenario, gasoline engine is going
to be more acceptable passenger vehicle prime mover, as it meets
BS-VI emission standard and also need less cost of up-gradation.
Schaeffler is well known for its variable cam phasing (VCP)
technology in automotive world. VCP is very well proven technology
and used by many OEM's globally to improve fuel consumption and
reduce engine emissions. Electric Cam Phasing (ECP) is an
integration of electro-mechanical system. In ECP, angle shifting is
independent of engine oil pressure, which allows a more aggressive
engine calibration of valve timing to minimize active intervention
in the ignition and fuel injection sequences. Early advance timing
makes it possible for the combustion engine to build up torque more
quickly during acceleration, which means that ECP not only helps to
achieve high operating efficiency, but also good driving
performance. This paper will describe use of advanced features of
ECP in achieving improved fuel consumption and reduction in HC
& CO emissions to meet BS-VI standard by precise controlling of
valve timing at engine start condition.
