English Electric diesel engines

From Wikipedia, the free encyclopedia

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.

[edit] Specification

The "K" type engine had 2-valve cylinder heads and ran at 630-680 rpm. The "RK" and "V" types had 4-valve cylinder heads, ran at 750-900 rpm, and were available with turbochargers and intercoolers.

• Number of cylinders:
  • K and RK types, 4 in line or 6 in line
  • V type, V8, V12 or V16
• Cylinder bore: 10" (254mm)
• Piston stroke: 12" (305mm)
• Power range: 60-170 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 = uncertain (believed to stand for "traction", i.e. rail use)
