IMPCO's Eclipse Engine Management System was featured in the September 2004, North American issue of Diesel Progress. See the article here.

The Eclipse product line is designed for the heavy-duty marketplace. It has been developed to provide engine management systems for both OEM and aftermarket engine applications. This technology can be used for both stoichiometric or lean burn engines and is offered in four series I, II, III, IV, which allows progressively more stringent emission standards to be met. The Eclipse technology can also be used for a wide range of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), bio-gas, and liquefied petroleum gas (LPG). 

The first diesel engine was stamped, “engine suitable for practical use” in 1897. In the early stages, stationary engines were exclusively built however in 1903 and from 1910 onward seagoing ships equipped with diesel engines began to appear. Following in the years 1923/24 the first diesel-driven lorries were built, and in 1936 series production of the first diesel car engine began. Today, we encounter the diesel engine used in transportation and industrial applications. It continues to deliver excellent fuel economy, torque and power. Diesel engines also have superior durability and provide low lifecycle cost. Although diesel engines have a long list of positive attributes, they do emit harmful emissions, some of which are potential carcinogens. Over the past decade emission regulations in North America and Europe have tightened (Euro IV and V and US EPA 2004 & 2007) which will make them more difficult to achieve and prove more costly. This has driven technology providers to adopt various methods to meet or exceed these standards. 

Generally speaking there are two markets for Heavy- Duty Engines, OEM and Aftermarket. These markets are then divided into transportation: buses, refuse trucks, cargo vehicles; industrial: compression, drilling, pumps; and power generation: primary and backup gensets. 

Applications
Transportation

Transportation applications are subject to frequent and aggressive transient cycling both in terms of engine speed and throttle opening. Emission testing protocol for most transportation applications includes significant transient cycling. Precise fuel and boost control during all phases of operation is requisite in order to attain target emission levels.
 

Industrial/ Power Generation Stationary

Stationary applications typically require fixed engine speeds such as 1500 or 1800 RPM for power generation or variable speed operation with minimal transient cycling. The demands these systems place on transient fuel and boost (turbocharged engines) control is not as rigorous as that required for systems used in transportation applications.  Depending upon specific operational requirements, including type of emissions testing protocol required, stationary applications can sometimes be de-contented relative to comparable transportation units.

In either segment, the Eclipse System is used with its corresponding level I, II, III or IV to meet emission requirements. IMPCO is the developer, innovator and manufacturer of this engine management system and maintains control of quality, service and integrity of the Eclipse system.  

In addition to IMPCO’s engineering specialty for these projects, we have strategic alliances with Lotus Engineering, pre-eminent engine vehicle designer and E-controls, a product engineering and manufacturing company specializing in engine control systems and instrumentation.

Technology Overview:

The Eclipse Heavy Duty Engine Management system integrates full authority fuel and spark controls to match domestic and international safety and emissions regulations.  

IMPCO offers an array of fuel metering technologies constructed in a building block approach based upon the industry proven air/gas Mixer, adding Solenoid and Electronic Pressure Regulation enhancements with Port Fuel and Hybrid Injection options characterized as Series I – IV.  The multiple levels of the Eclipse allows IMPCO to closely match customer performance and emissions requirements.
