Introduction
New Eagle is a developer of engine control systems including mobile industrial and stationary power generation. Our site includes components available, our systems and reference applications.
Engine System Components
New Eagle has an extensive supplier network to provide the best validated components at competitive prices. This offering includes a full set of components required for the design and manufacture of industrial engine systems.
For information on industrial parts/components please click here.
Industrial Engine Systems
New Eagle offers in-house system engineering services. We provide a full system design, taking into consideration component sizing and objectives of each specific application. Whether the system is targeted to meet EPA emissions, improve fuel efficiency or reduce overall system cost, New Eagle can tailor each system to any specification.
Low Pressure Natural Gas and Propane - EPA Emissions Capable
Our systems designed for low pressure natural gas and propane fuels range from a 2.3L 4-cylinder to a 6-cylinder industrial engine for jack pump applications.
- Compatible with natural gas and propane applications
- Robust against well head gas fluctuations
- Lowest cost solution for low pressure natural gas
- Custom solution for each application
Diesel Engine Conversion to Natural Gas
To better explain the capabilities of New Eagle's system engineering expertise, an example was drawn from our portfolio of applications. New Eagle designed a system to convert a diesel Navistar 7.6L to dedicated natural gas using multi-point fuel injection. The system enables the engine to achieve the following objectives:
- Transiently operable for Heavy Duty Class 6/7 vehicle use
- EPA Certified for Inside Useful Life up to Model Year 2011 emissions
- Diagnostic Trouble code detection and broadcast via J1939 protocol.
- Production ECU Hardware
The proposed ECU used for this system is the ECM‐0554‐112‐0904‐F which has a proven track record in other production applications for similar markets (e.g., Freightliner trucks and school buses).
- Wiring Harness
A new wiring harness was designed and revisions will be required for some applications.
- Software and Controls Development
This system includes a fully calibratable executable file with default values as part of the controls development portion of the project. An alternative that is offered is a fully modifiable Motohawk model. New Eagle has leveraged proprietary software modules to build a software platform that has validated building blocks.
- Calibration
Some customers require calibration support. As part of this system, a small engine calibration development program was considered. Calibration is offered as part of a turn-key solution for customers who do not otherwise have that expertise in-house.
- Combustion Concept
The combustion concept for a 7.6L Navistar turbocharged, spark-ignited, diesel engine was originally designed to be operated with diesel fuel. Due to CNG’s high peak temperatures, NOx formation is more prevalent than with other fuels. Retarding spark would reduce the cylinder peak pressure, leading to a reduction in NOx but, as research confirms, this strategy can result in adverse engine conditions since retarding spark leads to higher exhaust gas temperatures causing premature failure of exhaust components.
An option has been designed into this system to install an externally cooled Exhaust Gas Recirculation (EGR) system – similar to what Cummins Westport does on their engines. This simple system would consist of an EGR cooler and an electronically controlled EGR valve as well as an Intake Manifold Oxygen Sensor to measure oxygen concentration and calculate EGR rate. The effect of externally cooled EGR is to provide enough charge dilution into the cylinder to prevent high exhaust gas temperatures and inhibit NOx formation.
- Mass Air Flow Sensor
New Eagle proposed to use the Mass Air Flow sensor as the main load-sensing device. Using a mass flow sensor reduces calibration time – the MAP sensor is still required for boost control.
- Digital Camshaft Sensor
This sensor is necessary to run on the ECM‐0554‐112‐0904‐F, which currently does not support the Variable Reluctance cam sensor on the Navistar 7.6L
- Bosch NGI2 – CNG
Bosch NGI2 injectors are designed for natural gas port-fuel injection and are supported by the 112-pin ECU (ECM‐0554‐112‐0904‐F).
Low-Cost Throttle Body Injection Systems
New Eagle has designed a cost-effective and efficient propane electronic control throttle body injection system that complies with EPA/CARB regulations.
The identified market is airport Ground Support Equipment (GSE). Older generations of Ground Support Equipment still use gasoline carbureted fuel systems. Emissions regulations, fuel cost and increased uptime are driving GSE operators to transition into fuel injection systems. AFI is the standard for gasoline throttle body injection conversion kit distribution and New Eagle supplies the engineering support and controls. New Eagle and AFI have strategically partnered to develop a propane dedicated kit. Propane provides a green footprint and is preferable for exhaust emissions operation in enclosed baggage areas.
In addition to propane conversion, the system also includes electronic throttle control, drastically improving the airport tug’s drivability and speed governor behavior when loaded.
