Visit Preferences to set your user name Summary of change: ==== CommonRail - High pressure electronic diesel injection ==== ---- :'''Aftermarket controllers:''' http://www.bankspower.com/Tech_SixGun_Cummins.cfm ---- :'''Technical papers:''' Modelling pressure waves in the rail http://www.vehicular.isy.liu.se/Publications/MSc/00_EX_3081_KA.pdf Paper on the effect of timing and duration of main and pilot injection. Mainly conserning noise levels. http://www.macchine.unisa.it/meca01/papers/MECA01_paper06.pdf Modelling of a diesel engine common rail injection system http://www.nt.ntnu.no/users/skoge/prost/proceedings/ifac2005/Fullpapers/04315.pdf Achieving lower exhaust emissions and better performance in an HSDI diesel engine with multiple injections http://www.tytlabs.co.jp/office/elibrary/ereview/rev373epdf/e373_009hotta.pdf Optimizing the multiple injection settings for a HSDI diesel engine http://books.google.com/books?id=-F7lKlRtKuIC&pg=PA123&hl=sv&source=gbs_toc_s&cad=1&sig=snbLjPZM0vEGKR5kGE_yAIhb7_s ---- :'''Issues:''' AFAIK there is no general aftermarket common rail diesel ECU available. This makes it impossible to use a common rail diesel in applications where the stock ECU does not work. One popular application can be marinisation of car engines. Another might be putting modern diesels in older cars. Or for tractors or gensets or whatever... One critical thing would be timing for injection ---- :'''Timing:''' pilot injection ~ -40degrees (2-4mm^3) Timing not critical. Optimal timing is dependant on load and revs. Main injection no load -2 - 4 part load -6 - 4 full load -15 - -6 duration 40-60 deg crank 5000 crank rpm = 5000 / 60 rps = 5000/60 * 360 degps = 33us/deg average unexpected delay = 7us = 7/33 deg = 0.21deg ---- :'''Electrical Requirements:''' Like voltage and current of injectors ---- Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
