Sei que não costumo postar muito, mas achei um artigo que pode contribuir pra discussão.
É sobre um projeto para colocar um motor diesel no Abrams, feito em 2013.
Specific GDLS supplied figures for the ABCT with
dieselized Abrams are $57,636 per mile (14 percent reduction), while also creating a 300+ mile range for all vehicles, decreasing fuel truck drivers by 14, decreasing 5,000 gallon fuel tankers by three, and decreasing 2,500 gallon fuel tankers by four.
“We just came out of validation testing on this [dieselized Abrams] design with TARDEC [Tank Automotive Research Development and Engineering Command] at the end of September,” Cannon said. “And they’ve validated our numbers.
So basically this vehicle design uses 50 percent less fuel on a combat day than a turbine-based Abrams.
“And that’s with better performance,” he added.
“The modern diesel has greater torque in it than the turbine does. And you’ve got a couple of other things going for you as well. First, we’ve changed the nuclear, biological and chemical protection system, so it doesn’t operate off of the engine. On the turbine it operated off of ‘bleed air,’ so you had performance degradation on the turbine when the NBC system was on – and it’s on quite a bit. So that helps. Then, at idle, this [diesel] vehicle uses less fuel than if you put an under armor auxiliary power unit in there.
And it’s quiet – it’s very quiet. The heat that comes out the back of the engine is 300 percent less than what was coming out of the back of the turbine. So there’s a significant reduction in heat signature and you can actually stand behind the tank now – when it’s running – and have a conversation.”

Pra mim, parece uma proposta muito interessante, que sanaria alguns dos grandes problemas que teríamos ao operar o Abrams.
