Generac Knows Engines.

Engine manufacturing is nothing new to Generac. As a matter of fact, we’ve been developing industrial grade engine systems for over 40 years. This expertise has once again been used to bring proven and reliable engine technology to the marketplace with the introduction of our latest engine powerhouse, the Generac Industrial 8.0L V8 engine.

Suggested Applications:

Industrial off-road Agriculture / Irrigation Gas compression Oil fields Power generation

  • Specifically designed for LP and natural gas.
  • Cylinder head and valve train are engineered specifically for use with
    gaseous fuels and are optimized for long life, maximum endurance and
    minimized down time.
  • Short block is designed for heavy duty industrial applications and
    manufactured with 100% new components.
  • Compatible with readily available aftermarket gas compression
    engine components.

8.0L V8 Long Block Assembly

The Generac Industrial V8 engine comes standard as a long block assembly, with the following components included:

  • Cylinder head and valve train
  • High torque forged crank shaft
  • Forged connecting rod
  • Forged aluminum pistons
  • Molybdenum metric piston rings
  • Large eight quart oil pan
  • Harmonic balancer
  • Die-cast valve and timing covers
  • Flywheel

Cylinder Head & Valve Train Assembly

Due to the lack of lubrication in LP and natural gas fuels, valve
train components are the most vulnerable to the effects of
excessive heat because of the metal-to-metal contact. The result
can be premature engine failure. Over time, lack of lubrication
affects both valve train geometry and valve lash. To deal with
these demanding operating environments, the engineers at
Generac have implemented over 40 years of dry fuel experience
to develop a greatly improved industrial valve train that utilizes
heat dissipating and low-wear materials specifically suited for LP
and natural gas powered engines.
