another 110 mpg magic engine? For real maybe - Page 9

 

Napier had a long history of struggling to make exotic high-
performance piston engine designs reliable:

The Deltic clearly worked and powered fast boats and trains (diesel
electric).  A US company had one similar if my memory is right.

Oh my favourite engine from back in the day.  I loved the noise those
twin Deltic loco's used to make.  They've got a class 55 on my local
nostalgia railway line.  I think it's running next weekend, maybe time
for a trip back in time.

Don't fancy being asked to set the timing though.

With co-generation of electricity from the hot exhaust gases to drive auxiliary
electric motors, large marine diesels can get around 70% overall efficiency. And
they have pistons. Plus it gives them warm water for shipboard services. MAN are
particularly good in this respect IIRC.

 A 110 mile per gallon engine would be using .327 kwh per mile, or
about 3 mile per kwh. Gasoline is 32MJ/liter

 

I think you missed something out. What is your point?
