Doing a quick Google search of the site didn't give too many results, so I figured I would make a thread.

The question can be elaborated as such, usually when you register a vehicle, the paper work at your DMV, government office, et cetera has you put down information like "No. of Cylinders", "Body Style", "Doors"(thats a rare one I admit), and stuff along those lines. Now for our car those can be a little difficult to answer, we are somewhat unique in many of those categories. So what did you put down?

 

0 cylinders, 4 door sedan. Same as everyone else puts down.

Interesting, my in-transit permit states that its a 4 cylinder...

 

I think mine is a 2 cylinder 4 door sedan.

 

^Ditto.

 

2cyl 2 door coupe... (I've argued to death about the rear doors and eventually gave up)

 

i think my insurance tried listing it as a two door. emmissions computers in pa has 3cyl as the lowest #. i always say i wish

 

New Jersey considers it a 2-door because the rear doors cannot be opened independently.

When I bought the car, I had the dealer type on the invoice "Mazda certified four-door family sedan" to prove to my wife and mother-in-law (especially) that it was not a sports car. Didn't work, of course, but we thought it was funny.

We don't have any cylinders, but we do have six pistons, at lest that's what Felix Wankel and the other Germans thought when he called it a Kreiskolbenmotor.

 

See I would like to put "Cylinders" "0", but I think the Connecticut Department of Motor Vehicles won't allow a "Fuel Type" "Gas" engine to have zero cylinders. Also, I could go with the in-transit plate from New York and put "4" cylinders... guess they went with that at the dealership due to the number of plugs

 

I was thinking that most would be registered as coupes, due to the rear doors being kinda small and unable to operate without the front doors open. I know Mercedes had (maybe still has) a car they call a coupe with four doors, can't recall what model it was but I had a cousin that owned one for awhile.

 

Well that translates to circle piston motor, or rotary piston motor. 'Kreis' could also be used as orbital, as in planetary motion, which fits the rotary engine pretty well. I'll certainly agree that we have six "piston faces"

 

I guess it depends on how you define piston. A modern dictionary might define it as something within a cylinder, but etymologically, I think a 'piston face' is all that is needed, something that does the 'pounding'. From etymonline:

 

Iowa has mine listed as a 2 cyl. 4 door coupe.

 

Just got back from going through emissions(Connecticut has emissions but no inspections). For the "Cylinders" field Connecticut puts "R", so that kinda neat.

 

Mississippi listed mine as a 2 cylinder for tax reasons so instead of the $280 tag price I should have had to pay I only had a $89 tag price. Lucky for me.
