high pressured fuel system - before the injectors stable high pressure delivered equaly to all injectores wich provide a much more effective fuel jet/spray... which is more easyly burned and able to disctribut it self move evenly inside the combustion chamber

what is the common rail

Best all-rounder in class.

why?

grnjiant (January 1, 1970 at 12:59 am)

it swirls the fuel for more efficient combustion

eventually the built up particles get burned off from the high exhaust temps

fucking EGR!!!

oh! yes indeed... also details to consider to those designs.uhm ...so... about the marine enginesthey take lots of damage with the salt environment... i supose. So, the reliability is restored with a less agressive mechanical design.

Compression on 20's for a turbocharged engine is still too much. Note another relevant thing: the manufacturers refers to the geometrical compression ratio, but we must take in consideration the real compression ratio, which takes in consideration the delay on the closing of the intake valve(s).Only a curiosity: the MTU marine engine 1163 series, turbocharged to 3.2 bar at maximum power, has a compression ratio around 9,5:1. Incredible, isn't it?

grnjiant (1 hour ago) ah!!... there is also a little spark that ingnites from the tip of the injector to the top of the piston, not seen in this vid... to replace the lack of that ultra high compressionsee the "common rail" video
