Archival notes for ECN4:

We are pleased to announce that the 4th workshop for the Engine Combustion Network will be held in Kyoto Japan shortly after the JSAE/SAE 2015 International Powertrains, Fuels & Lubricants Meeting. The goal of the ECN is to promote the development of predictive engine combustion modeling for the design of more fuel-efficient, low-emission engines. The ECN provides highly leveraged, vetted datasets for spray and engine combustion model development by utilizing contributions from many experimental and modeling participants at pre-selected operating conditions appropriate to engines. Workshops are held to coordinate this research. Organizers gather experimental and modeling results prior to the workshop to allow a side-by-side comparison and expert review of the current state of the art for diagnostics and engine modeling, and to identify needed future directions.

ECN4 Objective and Program

The topical areas chosen for ECN4 will build upon recommendations from past workshops and current research pathways. The ECN4 group topics, guidelines, and leaders are listed below:

ECN4 Participation

Experiments and simulations will be performed based on these guidelines. Workshop organizers will collect and synthesize results before ECN4. Please let topic organizers know if you will make a contribution to one of these topical areas and if you are willing to serve in one of topical area committees (1-10).

ECN4 Calendar

Most ECN web meetings are on the first Thursday of every month. The purpose of these web meetings is for the presentation of the latest experimental and modeling research from individual institutions, but it should be coordinated with one of the ECN4 topic leaders. Agendas will be advertised in advance to allow participants to stay in attendance or drop in/out as needed, and the web meeting will be recorded for convenience (see video links above). Topic organizers will coordinate the guidelines for experimental and modeling submissions, and make arrangements to collect these submissions for analysis. The deadline for all experimental and modeling submissions will be approximately 3 months before ECN4, and earlier submission is encouraged. Lead time is needed to resolve questions about the data, ensure uniformity and standardization, and provide time for analysis BEFORE ECN4.

Location

The meeting will be held at the Kyoto University Clock Tower Centennial Hall (2nd floor): Yoshidahonmachi, Sakyo Ward, Kyoto, Kyoto Prefecture 606-8501 Japan. Reach the venue via a 30min chartered-bus-ride from Kyoto Station (free for ECN4 registrants, departing at 8:15 am each morning). Recommended hotels around Kyoto Station are given in this pdf. Hotels are readily accessible to the chartered bus stop at the Hachijo exit (south) of Kyoto Station (also shown in the pdf), and are also within walking distance of the venue for 2015 JSAE/SAE PF&L Meeting held just before ECN4 (for more information, visit 2015 JSAE/SAE PF&L Meeting website). Also see instructions for the “final session” of ECN4, a hike in historic Kyoto together with ECN participants.
