|Low Emission Idle (LEI)
Benefits of the ECI Low Emissions Idle System
|ECI's patented bank idling system effectively reduces particulate and HC emissions under low load conditions.
What is LEI?
Energy Conversions' patented Low Emissions Idle (LEI) system is supplementary hardware designed to fit EMD engines to reduce smoke under low load conditions. LEI is an electronically controlled linkage that powers left and right cylinder banks alternately while the engine runs at lowest speeds. The system improves fuel burning efficiency and significantly reduces unburned hydrocarbons and exhaust opacity.
Compatible with any standard EMD diesel , as well as General Electric's FDL series engines, LEI is a very quick, practical, and economical way for you to reduce visible emissions in switch yards as well as in long haul service.
How it works
Low Emission Idle (LEI) is an alternating bank idle system. LEI runs the engine on half of its cylinders when the engine is operating in modes of low engine specific power output (at idle or low RPM). The additional load the non firing cylinders place on the engine cause the firing cylinders to burn diesel fuel more efficiently. This results in fuel savings, and a significant reduction in the level of unburned hydrocarbons and the emission opacity in the exhaust. Cleaner exhaust is also apparent when throttling up after extended periods of idling, a result of cleaner and more complete combustion at idle. An electronic timer controls the switching tasks and alternates between engine banks. In operation the diesel fuel is cut off to one side of the engine by the use of electronically controlled pneumatic rams. When the LEI system is active, a slight momentary droop in engine speed is detectable when the engine changes operational banks, about every two minutes.
