No, not electric

If you find the engine type, you'll quickly have it solved!

atkinson?

guido66 · December 04, 2009, 11:12:08 AM

no, this car is a modified standard car with it's original engine. This car has been produced for over 20 years.

Otto Puzzell · December 04, 2009, 11:15:21 AM

But that car didn't have an ordinary internal combustion engine, and was not steam, compressed-air or turbine-driven.

guido66 · December 04, 2009, 11:18:11 AM

You didn't ask about an ordinary combustion engine??? You only asked about Otto-cycle or diesel. Which leaves one common engine type unaccounted for!

Paul Jaray · December 04, 2009, 11:25:53 AM

Two-stroke engine?

Otto Puzzell · December 04, 2009, 11:26:55 AM

D'oh!

Other, non-conventional power source (i.e., not otto-cycle or diesel)?

Two-stroke engine is an Otto-engine as well!

I beg to differ

Allemano · December 04, 2009, 11:42:19 AM

seems there at least different definitions available.

guido66 · December 04, 2009, 03:12:57 PM

Ok, let's focus on the car again:

two-stroke base model, was in production for over 20 years

I had never heard of that one [Day cycle].

You have, but perhaps not by name: it's the normal chainsaw (and SAAB) two-stroke.
Quite different from Herr Otto's cycle which is four-stroke.

guido66 · December 04, 2009, 03:35:57 PM

That was rather difficult to find, because of the very common word day. You learn something everyday here.

So Joseph Day invented a two-stroke engine and so did Dugald Clerk

Otto Puzzell · December 04, 2009, 04:14:43 PM

That's another reason I love this place. I learn something every day.

and then there was Wilhelm Oechselhauser, whose twin-piston two-stroke formed the basis of the Junkers Jumo diesel aero engine (licence built as the Napier Culverin), the Commer TS3/TS4 lorry engines and the Napier Deltic railway engines.

That's a Jumo 205, by the way.

Otto Puzzell · December 06, 2009, 07:08:31 AM

Any tie to the King Midget?

guido66 · December 06, 2009, 02:41:25 PM

no, not related

ImpishGrin · December 30, 2009, 10:56:58 AM

Ok, first the base car - was it a passenger or a commercial vehicle?

guido66 · December 30, 2009, 04:45:22 PM

based on a passenger car

Otto Puzzell · December 31, 2009, 02:52:49 AM

A Saab?

guido66 · December 31, 2009, 05:46:31 AM

No, not a Saab

Allemano · December 31, 2009, 06:15:57 AM

DKW based?
