Price Comparison For Diesel vs. Natural Gas*
Data acquired from EIA.gov

Dual Fuel Conversions
Conversions of large diesel engines to dual fuel, including natural gas, methanol, ethanol, diesel, ammonia, and hydrogen.

Low Emission Idle (LEI) System
Bank Idling System designed to fit EMD and GE FDL engines to reduce smoke under low load conditions.

100% Gas Spark Ignited Conversion
Conversions of large EMD diesel engines to 100% spark ignited natural gas.

Single-Point Injection
Fumigated single-point injection kits for dual fuel conversions.

Multi-Port Injection
Port injection, multiple point injection kits for dual fuel conversions.

Direct Gas Injection
Direct injection kits for gas injection into combustion chamber for engine conversions.
Global Warming Reduction
Natural gas is a great midterm solution with one of the highest hydrogen to carbon ratios when compared with other fuels. A diesel to natural gas conversion reduces carbon emissions, nitrogen oxide (NOx), and particulate carbon emissions.
Clean Burning EE System
100% Natural Gas Conversion
EPA engine certification to Tier 3 with no exhaust after-treatment or exhaust gas recirculation (EGR).
Benefits of Dual Fuel Conversions
Direct Benefits
- Fuel cost savings
- Significantly reduced emissions in dual fuel and gas modes
- Retrofit system—expands capability and adds value to your present investment
- Lower maintenance costs & improved engine longevity due to cleaner fuel
- Retains diesel-only versatility
- Fuel flexibility reduces costs when fuel prices are volatile
Indirect Benefits
- Reduces national dependence on foreign oil
- Environmentally responsible technology
- Shifts major fuel cost to a more price stable fuel medium
- Flexibility in storing fuel (i.e. diesel lasts 6-12 months in storage, natural gas lasts 20+ years)
