Lister Petter Limited – other nonroad diesel engines: the collective page of the water-cooled LPW range (2 to 4 cylinders) outside the named models, 10 to 30 kW, Interim Tier 4, from Dursley, England
Lister Petter, headquartered in Dursley, Gloucestershire, has built diesel engines for farm machinery, generator sets and pump drives since the 19th century and is one of the long-established British engine makers. This page gathers the versions of the water-cooled LPW range the register could not assign to a named range; the LPWS2, LPWS3 and LPWS4 designations in the version column give the cylinder count (2, 3 or 4), LPWST4 the turbocharged four-cylinder version. The EPA engine-family codes such as CL5XL1.86VNI encode the 1.86-litre displacement.

The register lists here 17 versions with 10 to 30 kW rated output at 1,800 to 3,000 rpm, from two- to four-cylinders in-line with 86 mm bore and 80 mm stroke. Maximum torque ranges from 53.3 to 126.3 Nm, also at 1,800 to 3,000 rpm. Injection is indirect, the fuel specified is diesel with 300 to 500 ppm sulphur, the emission stage is uniformly Interim Tier 4 in the 19 to 37 kW power category. Among the engine families, CL5XL1.86VNI leads with 7 versions ahead of CL5XL1.86FNI with 5, CL5XL1.86CNI with 3 and CL5XL1.86FTI with 2; among versions, LPWS4 leads with 9 ahead of LPWS2 with 4 and LPWST4 and LPWS3 with 2 each.
LPW engines chiefly drive generator sets, pumps, compressors and stationary drives in the lower and mid power segment; Lister Petter supplies both its own gensets and numerous outside manufacturers who, in the UK and international markets, rely on the LPW design proven over decades.
When buying used, operating hours and the service history of the injection pump, the condition of the glow-plug system and cold-start behaviour on the indirect-injection engines, the tightness of crankshaft seals and valve cover, and, on the turbocharged LPWST4 versions, the condition of the turbocharger matter; spares for the LPW range are usually well available through the Lister Petter dealer network even for older model years.
