(Olle) Schjolin in charge of it. It could be the only remaining example of this Antique Victorian Troemner Oak small but interesting genre. Also, the Tiffany & Co Atlas 15-degree phasing in the side-by-side bores allowed the exhaust to open far ahead of Antique 19c Victorian Burnished the intake, yet both ports closed at the same time. Both Martias and the AD-800 seated four and delivered up vintage 1930s old zenith black dial art deco depression era antique tube radio to 45 mpg. Unlike the previous cutaway, this schematic shows exhaust gases being drawn from the crankcase. And because two-strokes don’t burn all the fuel mixture totally, part of the exhaust stream was rerouted around the supercharger and back into the intake. Unfortunately, Reo was unable to finance production during the Depression and the company stopped building cars two years later to concentrate solely on trucks. Why would you have the scavenger pump on the exhaust side? ” But by force-scavenging both the 130 and the 160 with the same-sized pump (supercharger), the team found that the larger engine had less blow-through Antique Acoma Nm Pottery Bowl and a less obnoxious exhaust smell.
Michael also wrote about this car in the early seventies while it Genuine Natural Dark Coral Discs Graduated Necklace was still in the Brooks Stevens collection. Michael Lamm May 31, 2015 at 11:52 pm I don’t know what eventually happened to these cars. GM’s effort began in 1929 when Charles F. Schjolin and Lindblom found that offsetting the pistons gave a smoother idle and Antique Drago French got Antique Pittsburgh Reverse Painted Floral Glass rid of the typical two-stroke’s poppety-popping on deceleration. Thomas completed the little prototype, which he called the Doodlebug, in the summer of 1933.

It was a mystery back then Mission Quartersawn Oak Arts and, even though we have discovered more of the story, there is still much to be learned. Website Developed by. One piston took care of intake and the other performed exhaust functions. Cunningham June 1, 2015 Vtg Antique Hand at 7:32 am One other interesting tidbit about the Marti cars: They were intended to sell in the economy class at under $500 per car. Kettering, head of GM Research Labs, inspects Martia I during a shakedown run near Gaylord, Mich. All vintage 1930s old zenith black dial art deco depression era antique tube radio Rights Reserved. Air flowed into a set of louvers above the rear fenders and exited through vents on the engine cover. This was strictly an experimental engineering project. The engine alone is a fascinating bit of engineering. Meanwhile, during WW-II, another team of engineers installed variants of the two-stroke X-4 in otherwise stock Chevrolets and Oldsmobiles.
Lindblom and a small, dedicated staff. The left front door interchanged with the right rear, and the right front door interchanged with the left rear. Most of this was well established by the time of any 20’s 30’s American experiments. The first car LOOKS LIKE DR. An Entertaining & Informative Vintage Automobile Internet Magazine Gooding Pebble GM’s Rear-Engined Experimental 1930s Economy Antique Estate 14k Tri Tone Cars By Michael Lamm: From 1934 through 1938, General Motors built three small, rear-engined, experimental economy cars.
Henry Ford started the development of an X-8 possibly as early as 1920 and Antique Gorham Sterling Silver Serving Tray Landsdowne some sources tell of as many as a couple of dozen of them being made. Edwin June 7, 2015 at 1:12 am THE “TWINGLE” engine has been Best Buy On Citizen Ca0525 50L used for many years on Antique Large Afghan Kilim Carpet MOTORCYCLES, Garelli starting in 1912, (German) Triumph, Steyr-Puch (SEARS), & others, its advantage being a combination of 2-stroke & 4 stroke technology. As with this Martia design one effect was to allow the exhaust port timing to be designed for better scavenging as well as reducing loss of fresh gas to exhaust on the upstroke. Thank you for posting this article. The light-car research experiment must have been quite expensive, even by General Motors standards. Two-stroke engines used a Roots-type supercharger to extract the exhaust, vintage 1930s old zenith black dial art deco depression era antique tube radio Antique Brooch Art Nouveau not to boost intake volume. Second, recycling spent exhaust would do nothing to improve volumetric efficiency, so that claims of 45 mpg in a vehicle weighing not far short of a ton are difficult to credit. If they were like most experimental GM cars they probably ended up being destroyed. Experimental 2-stroke engines powered not only the three prewar compact cars but also an Oldsmobile and a Chevrolet during WW-II and later a Cessna airplane. The first car had triple radiators, two in front and one above the engine. I own several right now, I believe that the Iso version of the Isetta( the original) also used a split single.
All engines worked well, but the Antique Estate Flowers 14k White Gold main objection was their exhaust odor, vintage 1930s old zenith black dial art deco depression era antique tube radio which one engineer described as a combination of tear gas and skunk. May 31, 2015 at 2:34 pm I don’t know, maybe Michael vintage 1930s old zenith black dial art deco depression era antique tube radio will know more about them. George Hallett, one of the engineers I talked to about this project back in 1971, said the exhaust smelled ” like a combination of tear gas and skunk. First the Roots “sucker”, instead of a blower. His team would soon build a Superb Royal Antique second version, Martia II, and then a final one, named AD-800. Thus at top dead center, compression was held for a longer time. Kettering code-named the project “Research Light Car Body. Oil consumption was roughly 3000 miles per quart, and oil entered each engine through an external reservoir rather than being mixed with the gasoline. But the Martia intrigues on a number of grounds. Not sure what the efficiency would be where the pressure at the inlet varies from +ve to -ve with exhaust cycle. Nevertheless, an intriguing and courageous design adventure! Some of the exhaust stream was rerouted around the blower and back into the intake. I am probably wrong on that. All three used fully unitized Chinese Antique Rose bodies fairly unusual for that day and Dubonnet suspension units at all four corners. ” Another engineer, Marion Fast, told me, ” these were the stinkiest engines ever built absolutely impossible from an emissions standpoint, even in those days. Antique Hubley Dolly Dimple Girl The rotating and reciprocating parts can be viewed (above and below) at two different crankshaft positions. All three cars used three-speed transaxles specifically engineered for these cars. Ferdinand PORSCHE “written all over” its body & mechanicals (Like the wheels) Edwin 30 Steve Denner June 9, 2015 at 7:44 pm This design reminded me instantly of Antique Japanese Black Lacquered Wood Zushi the pre-war DKW racing motorcycles.

Cunningham May 31, 2015 at 9:46 pm Reo was another of the manufacturers that toyed with a streamlined, rear-engine car during the early 1930s. The supercharger acted not as a blower but as a scavenger pump so that, rather than forcing the fuel mixture into each working cylinder, it removed spent gases after combustion had taken place. Marita I also had a third radiator above the engine. Both Martias had twin radiators up front.
