Cat Trucks to relaunch C15 engine block to meet ADR requirements but promises no hardware changes to the motor
October 10, 2011
Cat Trucks will relaunch a tweaked C15 engine block to meet Australian design rules (ADR) requirements but has promised operators no hardware changes will be made to the motor.
The C15 has undergone minor changes to meet the ADR 80-03 15L requirement, including the addition of a crankcase breather. The engine software has also been recalibrated to reduce emissions.
“The significant advantage for Cat Trucks is that this engine does not require the use of EGR or SCR technology,” NC2 Managing Director Bill Fulton says.
Cat says the revised engine will deliver up to 550 horsepower and 2508N and that the 95 percent-plus particulate matter reduction is achieved using dual diesel particulate filters with passive regeneration technology.
It says ongoing tests show passive regeneration is effective at all loads and speeds, negating the need for a complex active regeneration system.
The package will also include a particulate monitoring system to continuously monitor backpressure and exhaust temperatures.
“This is a major technical accomplishment, which I have never seen done anywhere else in the world,” NC2 Vice President of Product Development Tom Baughman says.
“It positions the Cat C15 engine for compliance with Australia’s most stringent emissions regulations, while addressing Cat customers’ demonstrated needs for power, convenience and dependability.”
