The History of the Ruston RK range of Engines

The association of the name Ruston with the RK range of engines came about as a result of the acquisition of Ruston & Hornsby by English Electric in 1996 and the subsequent concentration of medium speed diesel engine production at the Vulcan works in Newton-le-Willow. In fact these engines are a development of the old Engine Electric engines tracing their origin to the first English Electric diesel engine, a single crank unit of 130 bhp which was launched in 1906.

English Electric developed the K series engine in 1934 and manufacture commenced a year later at their factory in Rugby. Originally this engine was only in an in-line configuration and had a 10 inch bore which was retained until the development of the Ruston RK 270 in the early 1980s. Shortly after the end of the Second World War in 1945 English Electric developed a Vee configuration of this engine with 16 cylinders which was manufactured at the Dick Kerr works in Preston. Further improvements were made in the next two years and in 1947 the RK engine was introduced for the first time, RK standing for Revised K. Originally this engine had only two valves in the cylinder head, but this was increased to four with the introduction of the RK Mk 2 engine in 1951. Further developments lead to the introduction of the RK Mk3 engine in 1962. The engine itself was solid and robust and the main development focused on increasing the mean effective pressure by improving the turbocharging and charge air cooling.

These engines acquired an enviable reputation for reliability. They were sold across the world generating power or providing propulsion in locomotives, vessels, offshore rigs, sewage treatment plant, water authorities, health authorities, universities, refineries, printing works, gas and electricity boards to name just a few applications.

The development continued with the metrication of these designs. The first Ruston RK270 entered service in 1982 with a 270 mm bore size rather than the traditional 10 inch. The high power to weight ratio of these engines made them particular favourites for high speed ferries. In 1985 a spark ignition gas engine was introduced the Ruston RK 270 GS. Then in 1991 the Ruston RK 215 was introduced and in 1992 the Ruston RK 270 Mk 2 followed. The last development of the original K engine was introduced in 2001 as the Ruston RK 280. Production of this engine was transferred to Germany in 2006 and it was redesignated the MAN B&W 28/33D. Now the name of Ruston has joined that of English Electric as part of the industrial history of Britain, except, of course for those hundreds of engines which are still running as a testimony to the engineering excellence creating of the products created in Newton-le-Willow
