Investigations on Power Enhancement and Reduction in Particulate matter in Four Stroke Compression Ignition Engines

The internal combustion engine (I.C engine) are presently backbone of automotive space and they find applications mainly for transportation apart from being used for power generation. Power development constitutes a challenge as only portion of the heat developed is converted to power and the rest lost. Frictional power lost is accountable and although the development of I. C Engines are over a century; reduction of various losses remains a challenge to the designers and automotive experts. Applications ideally need a highly reliable and robust source of mechanical energy from automobiles, locomotives, aerospace to electrical power generators to define better amenities for future needs. The power realized from IC engines suffers from inherent parasitic power losses, resulting from the piston cylinder mechanism, valve actuation and accessory power take off drives. Several mitigating measures to reduce frictional power losses are being tried out by manufacturers and designers in the automotive engineering arena, the main cause for engine power parasitic loss. Same been tried out in the past and are in vogue. Use of present technology being put to achieve power enhancement and friction reduction challenges is a motivation for this investigation work and to develop feasible measures which minimise the parasitic work losses. Proposed project is intended to be carried out based on the methods which are tried out by various researchers and their approaches to reduce frictional losses and enhancement techniques for power. This paper presents a literature review for the development journey into the various diesel engine power boosting/minimising Frictional Power Loss/Frictional Mean Effective power (FMEP) consumption techniques as well as aiming for a reduction in exhaust gas emissions. This work is proposed to model the design modifications with the suitable experimentation in a dynamic manner in a laboratory assisted under standard test conditions. Since the power cylinder unit (PCU) is the main cause for frictional loss, our focus in this paper will be to discuss the different design techniques used in the past as well as to explore future vistas. Proposed outcome is to develop an optimized cylinder liner design combined with a matching choice of engine lubricating oil grades tested under laboratory conditions.
