Re: XU series engines
18% is a pretty good savings on my fuel bill. That is definitely in the plus column, I also noticed on the non cab model the exhaust stack not turned up is it a downdraft exhaust and if so what direction is the exit.
Is the PS as bullet proof as it seems?
Everytime I see a chance to chime in with a useful answer it seems like you've already beat me to the punch! LOL Good job, GMan!
That's exactly right, the high injection pressures (26,000 - 29,000 psi) atomize the fuel so well that the exhaust is clean without any regen, and you can tune for more power, better fuel economy, or both. In the case of the XU5055, you'll get up to 18% better fuel economy than the U5030's Mitsubishi engine rated for the same output. Additionally these Shibaura engines, relative to the outgoing Mitsus, have a solid block / captured crank design, fewer internal moving parts since they use a serpentine belt, and a better lubrication scheme with dedicated oil lines providing positive lubrication everywhere it's needed in the engine.
We first started learning about these engines on a LS sponsored dealer trip to Korea 2 years ago, and then in tech classes beginning 1.5 years ago just before they became available for sale. The more we learn, the more we like! Other than one customer damaging his main wiring harness with some modification, they've been 100% trouble free so far, and we fully expect that trend to continue.
