Cat Low Emission Kits & Generators

HiVolEff Low NOx G3500 System

  • Lowers Nox Exhaust Emissions to Below 1/2g/bhphr
  • Proven Technology
  • Easy Installation
  • No Power Reduction
  • No Increase in Co Exhaust Emissions
  • Works on 8, 12, 16 & 20 Cylinder Versions
  • Improves Oil Life
  • Easy Installation

The Low NOx System installed on G3500 has proven to lower NOx exhaust emissions without losing power [1340 HP @ 1200 -1500RPM on G3516]. It is currently installed on over 60 engines throughout the USA, including emissions sensitive areas in California and Texas. Half of a gram per brake horsepower-hour of NOx or less can be obtained with no increase in CO emissions. The engine is limited to 1000 feet elevation and 100°F ambient without a power reduction. Use standard derating charts.

The HiVolEffTM Low NOx System increases airflow through the engine due to improved airflow efficiency. The added [air] mass in the cylinder with the same fuel energy input lowers the combustion temperature due to lower NOx emissions. Certified emissions test indicate that NOx of less than 80 PPM NOx can be obtained while CO is unaffected.


The system works with all G3500 engines with Electronic Ignition System (EIS) or ADEM III control systems with CAT® or Denso® spark plugs. It is also compatible with the Engine Supervisory System (ESS). Only slight adjustments to the wastegate and air fuel ratio control are required to meet the 1⁄2g NOx emissions.


The installation is simple and requires some modification of current engine components, which can be completed in typically 4-6 hours. The maintenance of the engine is not adversely impacted while oil life is improved due to less nitration.
