Cannot attest to the authenticity of the following, but I found it fascinating!



A 12-cylinder Nordberg diesel radial engine. This engine displaced 29,556 cu in (484.3 L) and produced around 2,000 hp (1,500 kW). Note the fuel injector in the center of the cylinder head.

The Nordberg radial offered several advantages over the stationary inline engines that were the current standard. With its cylinders horizontal, the Nordberg radial’s output shaft was in a vertical position. Although the engine was built primarily to generate power for the electrolytic reduction of aluminum, its arrangement was perfect for pumping applications. In addition, the configuration of the radial made it more compact and much lighter than a comparative inline engine. The Nordberg radial took up about half the space of an equally powerful inline engine and could be installed on a much lighter foundation.

The Nordberg radial was first introduced in 1947. The first engines were spark-ignition natural gas burning units that quickly established themselves as reliable and economical. These engines had two spark plugs located in the cylinder head. A single cam on the crankshaft actuated a gas valve for each cylinder. This gas valve allowed the natural gas into the incoming scavenging air for the cylinder.

Nordberg continued to develop the radial as its use spread to central power stations and various pumping applications, primarily for flood control and at sewage treatment plants. Nordberg soon developed a diesel version of the engine and a version that could run on a mixture of diesel and natural gas, which Nordberg dubbed Duafuel. The Duafuel engine could run on 100% diesel or as little as 5% diesel and 95% natural gas. This flexibility allowed the engine to operate with the most economical fuel mixture possible. In the diesel and Duafuel engines, the single cam now actuated a fuel pump for each cylinder, and the diesel fuel injector was in the center of the cylinder head.

I once waited 9 months for a pan gasket for a pre-war RR Phantom. When it arrived it was a piece of waxed twine in a small manila envelope. Needless to say, we machined a groove in the pan sealing surface and added an o-ring.
It was never going to see much driving but damn those old RRs leak oil.

I always wanted one of those until I saw that pic. They were used primarily as industrial engines.

This is more like it:

This one has been converted to EFI. Note the use of the standard SU carbs as throttle bodies.

Wow - I had no idea Alfa had a 1.5L flat 12 that put out 335bhp - w- years before the 917!
