[shiftbyear]

Is this the wave of the future for combustion engines?

The most interesting thing in that article is the Achates engine fitted is a gasoline, compression ignition version.

They claim 37 mpg and for the diesel fuelled version - 42 mpg. So why install the gasoline version for the show? Emissions?

is that the outfit that bought katech a couple years ago ??

The article reads like Ford had nothing to do with it except for the fact that they used a Ford truck ? Achates put the engine in the truck and is doing the testing. Not Ford. Or did I misread something?


"Achates Power and Aramco Services outfitted a truck..."

"In its diesel configuration, the same 2.7-liter, three-cylinder opposed-piston engine being demonstrated in the Achates-Aramco pickup"

That's not Ford? Look like it's all Achates-Aramco and the Ford truck is just a tool to test the engine. <shrug>

Well it says the same engine can be converted to run on multiple fuels. So maybe it's not as simplified as putting in one or the other. Maybe you wouldnt have to swap anything except the fuel. Considering a majority of US cars are gas, it make sense to me to have the gas version on display, considering there would be more of them on the road than diesel.

I would have thought a lot of US trucks are diesel? If your diesel version has 12% better fuel consumption, wouldn't you headline that?

Sounds a lot like a re-incarnation of the British Commer truck engine of many decades ago, commonly known as the ' Double Knocker'.

Most US light trucks are gasoline... the 8500 lb. and heavier gross vehicle weight jobs are likely 60/40 diesel vs. gasoline.

The vast majority of US privately owned trucks run on guzzoline.

Diesel is mainly used by hippies in VW Jettas and New Beetles, commercial trucks much heavier-duty than pickups (Class 8 style Large Trucks, Isuzu cabover style medium-duty trucks too, atlhough most of the new ones of those are powered by Chevy 6-liter gasoline engines), and brodozer hipsters who want to show off how much fuel they can throw unused out the tailpipe in the form of soot.

I have some friends who are VERY happy with their Ecoboost Fords. That 2.7 is a real monster.

All i can say is WOW! That is a 75 percent inprovement in fuel economy. If the life span of the motor is good, and has low maintenance, its' a world beater for sure. That would bring the total energy efficeincy up from about 40 percent to 60 percent?
