“…Downsizing is a very effective way of reducing BSFC in the entire engine speed-load domain, especially at low loads or high speeds (Mayer et al, 1982;Ecker et al, 2000;Ge et al, 2011;Saulnier and Guilain, 2004;Bargende and Berner, 2005;Banks et al, 2009;Fraser et al, 2009;Lumsden et al, 2009;Chadwell and Walls, 2010;Kirwan et al, 2010;Sisken et al, 2010;Thirouard and Pacaud, 2010;Gheorghiu, 2011;Pohorelsky et al, 2012). Downsizing (or even combined with down-speeding) at the same brake power means increased BMEP so that the engine speed-load modes re-defined by the US SET 13-mode or FTP cycle certification will all have elevated BMEP levels and hence lower BSFC and brake specific CO 2 emission.…”

Driven by a demand for better fuel economy and increasingly stringent emissions regulations over a wide range of customers and applications, engine manufacturers have turned towards engine downsizing as the most potent enabler to meet these requirements. With boosting systems becoming ever more numerous as the technical solutions to complex boosting requirements of the internal combustion engine increase, it is time for an overview of available and under development boosting technologies and systems and for a discussion of their relevance to downsizing efforts.The presented analysis shows that there are no standard solutions for all the different applications as the trends indicate a rising complexity to meet with the extreme boosting requirements predicted for the remainder of the decade. These trends include variable geometry, a shift from single to two (or more) stages, extensive actuation for bypassing exhaust flows, exhaust flow regulation and pulsating exhaust energy recovery, severe electrification and an extensive effort downstream from the turbine to capture waste heat after the principal turbocharger/supercharger system. engine downsizing, boosting technologies, boosting system Citation:Ricardo M B, Apostolos P, Yang M Y.

“…However, compared to conventional intake‐manifold fuel injection, GDI requires much higher injection pressures. In fact, up to 20 MPa are currently serial produced . Recent studies have reported that an increase in the injection pressure above 50 MPa should further improve both efficiency and performance due to the reduction on the fuel droplet size .…”

Tribological Performance of Aligned Silicon Nitride Ceramics under Isooctane‐Lubricated Oscillating Sliding Conditions

et al. 2015

Silicon nitride (Si3N4) materials with preferentially aligned β‐Si3N4 grains were tribologically characterized with respect to their possible application in a high‐pressure gasoline pump. Tribological tests were performed under oscillating sliding conditions lubricated with isooctane as a substitute for gasoline using Si3N4 counterbodies. Performance in terms of wear of the aligned materials surpassed that of nonaligned reference Si3N4, as well as that of self‐mated silicon carbide, zirconia, alumina, and a steel sliding pair. The plane perpendicular to the extruding direction and parallel to the hot‐pressing axis was the most wear resistant.
