NLIMIT
Monitors and manages engine operation to reduce fuel and exhaust emissions.
Cutting back on fuel has never been easier.
The NLIMIT reduces fuel consumption and exhaust emissions by monitoring locomotive operating parameters and automatically shutting down and restarting the engine during appropriate locomotive idle times.
NLIMIT's compact design allows for flexible installation in a variety of locomotive cabinets, regardless of manufacture or vintage.
Features
At the heart of On Track Control's NLIMIT is a powerful microprocessor and is based on a modular concept, allowing functions to be added later without changing the entire system.
NLIMIT's primary features include:
System indicators (lights and sirens) indicate the status of the NLIMIT system
Governor assist pump works in conjunction with the engine governor during restarts to provide sufficient fuel to start the locomotive
An engine protection device (EPD) override prevents false engine shut downs as a result of a false sensor reading
A LOS override holds pressure in the governor during shut down and restarts, which prevents faulty engine shut down as a result of LOS activation in the governor
Load shedding eliminates repeated engine restarts resulting from a low battery voltage conditions by turning off battery loads, such as the locomotive headlights and air conditioners
Automatic ground relay reset after every NLIMIT restart
High idle control helps maintain operational engine temperature in cold climate
Low idle control helps provide additional fuel savings when the locomotive is idle while waiting for an NLIMIT engine shut down
Additional recording functions such as locomotive kilowatt-hour or locomotive speed/distance
Benefits
Our NFORCE control system offers a wide suite of benefits to your operations, including:
Reduced fuel consumption
Reduced exhaust emissions
NLIMIT's integrated recording function records fuel report statistics, locomotive statistics, events, and alarm logs
