Suzuki 2 Strokes

Combines a two stroke motor & generator into one unit.
Currently an R&D development project.
Interesting bit of out-of-the-box thinking.

Interesting thinking, but complicated.
Whatever happened to simplicity?

That’s very interesting post about Toyota two stroke motor for hybrid/electric cars. I liked reading through this. Well, nowadays ECs are getting quite popular because they have various advantages. I also just finished reading Electric car buyers guide and got to know a lot of new things about them.

Cummins is developing a new two stroke diesel for the military. It uses opposing pistons and doesn’t have a head. “Cummins says it is targeting a 21 percent reduction in thermal rejection, along with a 50 percent increase in power density and a 13 percent jump in fuel efficiency compared to engines currently in use.”

Nothing new there. Its been done before. In the UK they had diesel engine trains that used a similar concept in what is called a deltic engine. They ran for many years, but so far as I am aware are no longer in general public use on the railways anymore.

it is annoyingly impossible to embed images from wikipedia, apparently.
I like the idea of the 2-stroke hybrid motor without a crankshaft though. Very interesting, without being overly complex in comparison to many modern motors.

Interesting.



Right click on the image & then open it up in a new window. Then use the new window’s URL.

ah thank you.
Pretty cool engine huh? I was in awe when i first saw it at the museum in York. I think I spent over half an hour just looking at the engine and trying to get my head around how it all works, then I came back later for another look. I spent more time with it than I did with any of the trains. Lol. Although, I spent almost as long with the Mallard. OMG what a beautiful train. I wish I was old enough to have been around when it was possible to ride in one.
Interestingly, the deltic engine didn't actually power the wheels, it powered the generator that supplied electricity to the electric motors that actually moved the train.
Oh bugger, I've got lost in a train of thought and hijacked another thread again.

That’s how diesel electric locomotives work. There is no clutch to burn up & you get 100% of the torque at 0 rpm.

Yes I know that now. Didn't know that until I went to the museum
