In order to analyze the spatial distribution of photo-generated charge carriers, the optical generation rate was computed with a three-dimensional (3D) rigorous coupled wave analysis (RCWA) tool developed at IMEP-LAHC[44].
But, at the same IMEP as the 4-stroke operation, the 2-stroke CAI operation results in 29% reduction in BSFC, indicating its potential synergy with highly downsized direct injection gasoline engines for much better fuel economy and performance.
In this work two piston bowl shapes, a standard re-entrant bowl and a bowl with a stepped lip, are tested experimentally and numerically at two part-load operating points (1500 rpm/6.8 bar net IMEP and 1750 rpm/13.5 bar net IMEP), and four full-load operating points (1500, 2000, 3000, and 4000 rpm).
According to the results of calculations, we conclude that IMEP is the better candidate for electroplating at high current density in comparison with JGB.
It is expected that IMEP should increase with timing angle advance to a point, and then drop off.
The results from electrochemical tests validate that MPS has both synergistic and antagonistic effect with IMEP and has an antagonistic effect with JGB.
Effect of error in these input parameters on estimated combustion and performance parameters like IMEP, combustion phasing, combustion duration, heat release rate, and maximum mean gas temperature are evaluated.
Further study on the transient development of in-cylinder flames shows that flash boiling spray leads to higher propagation rate of the blue flame, and a subsequent statistical analysis shows a positive correlation between IMEP and the propagation rate of the blue flame.
Two proficiency tests (PTs) were organised by IMEP on behalf of the EURL-HM using the same test item: IMEP-116 (for NRLs) and IMEP-39 (for official control laboratories (OCLs) and other laboratories), as defined in Commission Regulation (EC) No. 882/2004 (2004).
UNICEF has made progress since 2002 in creating a stronger organizational framework for results-based management, as demonstrated in the Integrated Monitoring and Evaluation Framework that accompanies the current corporate plan (MTSP 2006-2009), the requirements at the country level for IMEPs and a summary results matrix in the Country Programme Document CPDD).
IMEP represents the work done on the piston.
