Rusty_OToole Posted November 23, 2007 Share Posted November 23, 2007 Years ago I read in one of Tom McCahill's columns that Studebaker once built a straight 9 cylinder engine.The experiment worked well and was wonderfully smooth and powerful but they decided the public would not accept it, so it was never offered for sale.Has anyone ever heard of this?

Mark Huston Posted November 23, 2007 Share Posted November 23, 2007 As a collector, and enthusiast, of Studebakers for the last 33 years I have never heard of an experimental straight nine cylinder Studebaker engine. Although, I am not an expert and this is not to say that the Studebaker engineering department did not experiment with a nine-cylinder engine. I am wondering if the reference could have original been to the introduction of the nine main bearing engine on the President models in 1931. The first Studebaker President straight eight engines in 1928 were five main bearings, upgraded to nine in 1931. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted November 23, 2007 Author Share Posted November 23, 2007 That's a good suggestion. It would be a plausible way for a rumor to get started.I wouldn't dismiss the story out of hand though. Technically I think the straight 9 would work. Here is why I think so.The straight 6 has the smallest number of cylinders giving perfect primary and secondary balance and overlapping firing strokes.It is an optimum design in terms of smoothness, which is why such well regarded luxury cars as Rolls Royce, Mercedes, BMW and Bentley stuck with 6's for so long.A straight 9 with crank throws at 120 degrees would in effect be 1 1/2 straight sixes.Whether it would offer any advantage over a straight 8 I don't know.So it would make sense to at least try it out.This is why I believe the story to be possible. Whether they actually tried it or not, would be interesting to know.That's what has been nagging at me all these years.I do know various car makers built bizarre experimental engines, way stranger than a straight 9.

Oldsmobile built and tested a V5. You read that right - three on one bank, two on the other. I was unable to find the picture of it on line, but here's a news report from 1981:http://query.nytimes.com/gst/fullpage.ht.../Topics/Engines Link to comment Share on other sites More sharing options...
Matt Harwood Posted November 24, 2007 Share Posted November 24, 2007 Or Henry Ford's X-8, with four pairs of cylinders around a central crank (like a radial, I guess). Link to comment Share on other sites More sharing options...
Earl B. Posted November 24, 2007 Share Posted November 24, 2007 Rolls-Royce even made a 3 cylinder engine....B Link to comment Share on other sites More sharing options...

The Suzuki Sprint/Geo Metro had a 1.0L 3cyl - an optional turbo version was even available. My 78 JD tractor has a 3 cyl diesel. Link to comment Share on other sites More sharing options...
michel88 Posted November 24, 2007 Share Posted November 24, 2007 Speaking of 3 cylinder engines, I have 1974 Suzuki GT750 motorcycle. It has a 750cc 3 cylinder, 2 stroke, water cooled engine. It is a fun & very quick bike. Link to comment Share on other sites More sharing options...
Guest aussie610 Posted November 26, 2007 Share Posted November 26, 2007 daihatsu also did a 3, I had a charade with a 1.0 3Cyl, they also did a turbo version. Threes were common in the veteran era as well Link to comment Share on other sites More sharing options...
Dandy Dave Posted November 26, 2007 Share Posted November 26, 2007 Caterpillar also used a 3 cylinder Diesel in the model Diesel 40, RD-6, and also the early. D-6. This was in the 1930's and very early 40's. These were used until they started with the famous 8U and 9U series which all had 6 cylinder engines. Perkins also made/still makes a three cylinder diesel used extensivly in farm and construction machinery. I have one in a Massey Ferguson 30D Back Hoe. Ford also had one in the 60's and 70's in some of their diesel and gas tractors. A lot of modern compact tractors have them also today. Dave.

Restorer32 Posted November 26, 2007 Share Posted November 26, 2007 Yes but, did anyone actually build and use a 9 cylinder? Link to comment Share on other sites More sharing options...
