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.
