Products & Services

Energy Conversions Inc. offers innovative retrofit technologies to convert your engine systems to operate reliably and efficiently on natural gas. ECI systems range from basic gas fumigation with minimized engine modifications to optimized direct low pressure gas injection with revised after cooling and modified pistons.  ECI considers individual customer requirements to determine if their application is better suited for just a standard system or if custom options should be applied. To give you an idea of the types of configuration information we need to optimize your ECI system, we've placed a project questionnaire on our contact page. Please take a moment to look it over.

ECI Economizer Dual Fuel Conversion Systems

This kit is a relatively low cost way to get your existing four-stroke diesel engine running dual fuel. The Economizer is suitable for high speed, medium and low speed engines such as those used for power generation.

The conversion is simple, requires no major engine changes, and is affordable. Taking advantage of inexpensive natural gas as a primary fuel, you will also retain the ability to run your engine on full diesel without losing horsepower.

More details on the Economizer

 

Up to 90 % diesel replacement

Diesel-only capability for greater versatility

Electronically controlled, fully automated operation

Economical installation

Reduced engine wear

EMD Spark Ignited Gas
ECI 645SIP - Dedicated natural gas conversion system for the General Motors EMD 645 series diesel engines

This retrofit system allows any standard EMD645 to run on 100% natural gas. Ideal for locomotive switch engines and other applications with typically long periods of idling or any application where diesel backup is truly not necessary.
System includes: Specially designed pistons and heads, ECI spark-ignited prechambers, ECI electronic control and monitoring system, gas plumbing and control valves, Installation and Maintenance documentation. Available in 8, 12, 16 and 20 cylinder configurations.

100% gas replacement of diesel

A super-clean system, with 1-2 g/hp-hr of NOx

Fully automated operation

Cleaner fuel reduces engine wear and maintenance

logoEMD Dual Fuel
ECI 645E-DF Dual fuel conversion system for the General Motors EMD 645 turbocharged series diesel engines   

Our cleanest and most efficient system, the ECI 645DF conversion has all the necessary equipment for retrofitting a standard EMD 645 diesel to run on natural gas. The system uses 90% gas, with 10% diesel fuel for ignition, with nearly 70% reduction in NOx emissions over a locomotive duty cycle. Power generators will see even greater fuel replacement and emissions reductions. Maintains versatility of running on diesel fuel alone.
Kit includes
: Specially designed pistons and heads, ECI patented gas injectors, electronic control and monitoring system, diesel pilot fuel control, gas plumbing and special after cooling design, Low Emission Idle (LEI) bank idling system, and Installation and Maintenance documentation. Available in 8, 12, 16, & 20 cylinder configurations. (For more information, see
EMD specifications).

ECI 645E2 DF- Dual fuel conversion system for the General Motors EMD 645 series roots blown diesel engines

The blower style version of the ECI 645DF conversion, this system retrofits a standard 645 blower style diesel to run on natural gas, while retaining the ability to run on diesel fuel alone.
Kit includes: Specially designed pistons and heads, ECI patented gas injectors, electronic control and monitoring system, diesel pilot fuel control, gas plumbing, LEI bank idling system, Installation and Maintenance documentation. Available in 8, 12 & 16 cylinder configurations. (For more information, see
EMD specifications).

Additional Products

Low Emission Idle (LEI) - Bank idling system for GM-EMD and GE-FDL engines
LEI is a linkage system which mounts to an existing EMD or GE-FDL engine that allows the engine to operate on one bank at a time. This substantially reduces excessive smoke that can occur during low load conditions. A low cost way of improving visible emissions around the switch yard, port, or high traffic locations. (For more information see LEI page).


Fuel Storage Systems
Fuel Tender or Fuel car for locomotive applications can be for LNG or CNG types of gas storage. Tender page

Electronic Engine Control systems-
Energy Conversions' patented electronic controls are an essential component to all of ECI's conversions systems. Now you can employ ECI's technology to monitor and adjust your engine's vital operations.
Perform such tasks as electronic valve sequencing, pressure and temperature monitoring, emissions analysis, air balance, data acquisition and fault history, as well as special tasks such as skip cylinder firing. Proprietary software allows the operator to view and adjust functions through an easy to use on site interface or remote laptop computer. ECI will customize your electronic system to fit your specific engine requirements. Contact ECI for more details.
