The OVHI Engine

The only engine designed specifically for generator use. Why is this important? Generators are often required to run for hours at a time, day after day. Generac's OHVI engine utilizes the same type of pressurized oil lubrication used to give automobile engines long and trouble free lives. This means a significantly longer life than competitive engines-an unprecedented three to four times longer. That's the reliability you need for the long run times emergency backup can require.

Generac OHVI Engine	OHV/Lawn Mower Engine
Low Oil Pressure Protection When low oil level or overheated oil is detected, engine shuts down to prevent damage	No Oil Level Protection Engine continues to run even when oil level is low, possibly causing serious damage
Pressurized Lubrication System Positively lubricates from start-up to shut-down by pumping oil directly to every critical area	Splash Lubrication Internal engine action splashes oil on moving parts, missing critical friction areas
Automotive Grade Spin-on Filter Full pressure lubrication system allows for use of automotive grade oil filter to remove dirt and carbon solids	No Filter Many OHV engines do not have oil filtrations, relying only on oil changes to drain out impurities. This allows harmful debris to end up in the engine
X-Torque Governor Fastest responding governor available. Maximizes engine performance and virtually eliminates stalling.	Slow Governor A slow governor can result in poor/low voltage, potentially damaging to electronics.
