U engine

Wikicars, a place to your automotive knowledge

A U is a piston engine made up of two straight engines (complete separate crankshafts) joined by or chains. It is similar to the H engine couples two flat engines. The is also sometimes described as a bank or double bank although these terms are used also to describe V .




A British heavy tank in April 1916 was intended to be by a doubled version of the 105hp ‘Silent Knight’ engine, two banks of cylinders side by sharing a common crankcase. this was not a true ‘U’ as the cylinder banks were to been independent, each driving its own crankshaft and four-speed Neither the tank nor the engine ever made. [1]

The first U engine known to been built was the 16 cylinder litre displacement Bugatti aero engine designed and by Ettore Bugatti in 1915-1916. [2] licensed the design to Duesenberg in who produced about 40, [3] and Breguet of who built a few in the years after the end of War 1. [4] Bugatti later used the engine layout in the Bugatti 45 of 1928, but only two were

Matra developed a high-end prototype powered by a 2.6 L U8 engine of two Simca 1000 Rallye 2 connected by chains around However because of the petroleum this car was never put in production.

Several types of U-form engine have been produced, by companies such as Blackstone [5] and Sulzer Brothers A twin bank diesel for marine use is described in US Patent [6] However, no further documentation has found for any ship or marine of such an engine.

Sulzer Brothers developed a engine for rail traction of type, the LD series, in the 1930s, was in production for more than years. Several cylinder were produced, including the 19 190 mm), 22 (bore 220 mm), 25 250 mm), 28 (bore 280 mm) and 31 (bore 310 The engines of the LD and later, the LDA series, commonly found in 6 and 8 cylinders and 12 cylinders U form.

The U form engines were in railway locomotives operating in countries, including Britain, China, France, Poland and

Sulzer Brothers later the rail traction engine [7]


If the crankshaft on one bank of is made to rotate in the opposite of the crankshaft on the other bank, the gyroscopic effects of the rotating would be canceled. However, crankshafts would make the of the power outputs very

In the Sulzer LDA engine, a gear on each crankshaft meshed a slightly smaller gear on the central output shaft. The ran at around 750 rpm but the output shaft ran at 1,000 rpm. This the use of a smaller, and lighter, electrical when the engine was used in a locomotive.

This design was revived as a version on some racing and their subsequent road-going the Suzuki RG500. Although racing success was achieved, the bikes didn’t sell in numbers, and the design was phased out in of in-line, four-… designs, as at the two … engines were being superseded by more reliable, and emissions-friendly four-strokes.
