Most Efficient Common Rails

[McRat]

Are probably the new container ship engines. Everyone has seen the Interwebbythingy pictures of the Wartsila Monster Diesel, but I found an interesting older white paper about them:

Monster Diesel Common Rail Info

They use 3 injection valves per cylinder, and each one is capable of 3 events. When the ship does not need full power, they can effectively reduce the size of the injector by shutting down one or two of the injection valves and phasing them.

So it makes you wonder if you could stuff a second injector into where the glowplug goes, and run a totally separate common rail system for power enrichment. Center injector only up to 600HP, then turn on the second one for higher output.

Thats cool get to work:thumb:

I met a guy in Anaheim that's doing stuff similar to this. He holds the patent since 1990 or something.

Wouldn't it matter where the spray is pointing for proper combustion?

X2. That's what I thought when I was reading it.

if you were to do that wouldnt that be the same idea as an older IDI?

You might have to have blank nozzles burned with a side pattern or cut an indention in the pistons, but maybe not. You're not looking for fuel mileage or emissions, but instead, a way to dump over 5 times the factory fuel (>500mm3) every shot, but only after the engine can absorb that much fuel. It probably would not idle if two sets of >100% over injectors were on line, and you'd have spooling issues. Sure, you can reduce pressure to "fake" like a smaller injector, but with poor atomization.

Basically a "two speed" injector. Big as possible for low RPM, then twice as big once the engine is fully lit. About 2000HP worth of fueling without having to tow the truck to the start line and pray that it starts after 5 cans of Dodge Tuning Fluid.

Now, put some big ass wheels on it! :thumb:

I'm not having any luck finding a CP3 pump from that engine. One pump will support 7,000hp, so we can use just one for all three trucks with a long piece of hose between them.
