Description

All 645 engines are two-stroke 45-degree V-engines. Each cylinder is of 645 cubic inches (10.57 L) displacement, hence the name; with a bore of (230 mm), a stroke of (254 mm) and a compression ratio of 14.5:1.

The engine is designed with four exhaust valves in the cylinder head and charge air scavenging ports within the sides of the cylinders.

All engines use a single overhead camshaft per bank, with exhaust valves operated by two cam lobes (each of which operates two exhaust valves through a “bridge”) and one cam lobe to operate the Unit injector which is in the center of the four exhaust valves.

Rocker arms are roller-equipped to reduce friction while hydraulic valve actuators are used to reduce valve lash.

Like most EMD engines, the 645 is also sold for stationary and marine applications.

Stationary and marine installations are available with either a left or right-hand rotating engine.

We are capable to supply 8 Cylinders, 12 cylinders, 16 cylinders and 20 cylinders EMD Engines. As these are in Marine Application, Stationery Power application as well as Locomotive and rail application, Upon the Part Number we can provide liner, piston, head, connecting rod, crankshaft, camshaft, fuel pump, block, Turbocharger and Powerpack as well.

Along with a huge list of EMD used spares in our inventory, Marine and Locomotive Spares are also available in Genuine EMD and OEM EMD from our counterpart and sources.

Marine engines differ from railroad and stationary engines mainly in the shape and depth of the engine’s oil sump, which has been altered to accommodate the rolling and pitching motions encountered in marine applications.

*** Kindly let us know if you have a requirement of OEM Engine EMD Major Spares or Unused / Surplus and re-useable Marine / Locomotive Engines.
