English Electric diesel engines

English Electric diesel engines were manufactured by the English Electric company of the United Kingdom for both stationary and rail transport use. The range was derived from the "K type" engine (10" bore x 12" stroke), developed in the 1930s. These diesel engines were marketed under the English Electric name into the 1960s and, later, under the name Ruston-Paxman.

Specification

The "K" type engine had 2-valve cylinder heads and ran at 600-680 rpm. The Mark I "RK" and "V" types had 2-valve cylinder heads. The Mark II "RK" and "V" types had 4-valve cylinder heads. They ran at 750-900 rpm, and were available with turbochargers and intercoolers.

• Number of cylinders:
  • K and RK types, 4, 6, 7 and 8 in line
  • V type, V8, V12 or V16
• Cylinder bore: 10" (254mm)
• Piston stroke: 12" (305mm)
• Displacement: 942 cu. in (15.445 litres) per cylinder
• Power range: 60-275 bhp per cylinder
• Rotational speed: 630-900 rpm
• Cooling: water
• Designations (example, 12CSVT):
  • 12 = number of cylinders
  • C = intercooler
  • S = turbocharger (supercharger)
  • V = V engine
  • T = traction, M was used for Marine use

Usage

A large number of these engines were built and these are just a few examples:
