e-REX engine

Just came across this video, interesting technology similar to car air conditioner compressor, seems promising for the future of combustion engines.

This is interesting!

Too bad they uses this engine to drive a generator, then charge batteries, then power up an electric motor to finally drive the wheels rather than just use a clutch and gearbox.

Likely this engine has very little torque and a narrow powerband. You need torque to move a vehicle from a standstill. Some torque comes from the inertia of a flywheel, but every vehicle needs a gearbox to match engine speed to vehicle speed. The gearbox is also a torque multiplier but if you have very little torque to begin with, the gearbox is not much help.

This engine might be a better complement to a constant speed generator that requires very little torque once it is up to optimum electrical production RPMs.

That is the definition of the messed up world we live in...

Diesel over electric works well for trains…

Can’t watch video rn limited connection but it must have a scavenge blower or forced induction of some sorts. Opposed piston in old tech, this is kinda interesting variation. Seen something similar using a swash plate. I’ve worked on Fairbanks Morse opposed diesels, they were pretty retesting, designed for US navy subs. Also check out the British “deltic diesel”. That’s a marvel...

Opposed cylinder twin crank used for drones too.

The variable compression is a novel idea however.
