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 ---- :'''Issues:''' This will most likely first be a replacement ECM because of the small aftermarket for common rail products. So Bosch common rail is a good start to look at. 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 ----
