Cummins/ Achates Diesel

ScottG - the definition in the link you posted says "internal combustion" :o

Her's a hint: How many of the Multi-Fuel engines that were used in deuce-and-a-half 6X6s in the early to mid 1960s do you see in scaled -down versions for RVs and pickups?
None that I know of...

Then the age-old argument over "motor" or "engine".
You can have an electric motor, or a hydraulic motor, or an air motor. You can even have a vacuum motor.
But, when discussing internal combustion machinery, you can have an ICE (Internal Combustion Engine), or an External Combustion Engine. You can have a reciprocating engine or a turbine engine. You can have a gasoline, diesel, or multi-fuel engine.

Semantics can be such fun. Or, it can be a pain in the posterior. Call it as you see it, I quit caring long ago!
I am reminded of a welding course I took many years ago, sponsored by Eutectic. the company was on a crusade to differentiate between the machine used to weld (a welder) and the person who operates the machine (a weldor). Now, Eutectic no longer exists, and "welder" is used for both the person and the machine.
Oh, well....

While the press release stated the technology might be used in OTR trucks. I agree a scaled down version might be viable for lite duty trucks. Being a two stroke I doubt it would meet emissions but technology could change that.

you're right... Sounds like half ton territory to me...

When will Cummins stop calling motors “engines”?

Never and here is why "motors" run on electricity, while "engines" run on combustion or burns fuel.

Because motors use energy to make work (electric motors)and engines burn fuel to make energy.

My apologies for the following Cliff Claven moment...

While that's the definition I like, it is by no means official.
There's nothing in engineering that states a motor must be electric driven. To the contrary, the technical definition of a motor describes a device that among other things, can be an powered an internal combustion engine.
Definition of "motor"

OTOH, a Cummins engine is certainly that; an engine.

no problem with "engines" we have them on Jets that I fly :)

Thanks!
