Melbourne – 15 March 2012 – The Cat® C15 engine, certified as meeting Australia’s ADR 80/03 emissions standards, is available in the next generation Cat CT630 which is scheduled for delivery in late 2012.
The updated Cat C15 engine, which is based on the well-proven EPA04 Cat ACERT™ C15 engine platform, launched at the Melbourne Truck Show, March 2012. It will deliver up to 550 HP and 1850 Lb-ft of torque. The engine has the service and support of the Cat dealer network.
“We’re pleased to confirm that the proven Cat C15 engine is available in the Cat CT630 in the ADR 80/03 format,” said Bill Fulton, managing director for Cat trucks in Australia & New Zealand. “There are minimal changes from its predecessor engine, which met the ADR 80/02 standards.”
Emissions Solution Required No Hardware Changes
No significant hardware changes have been made to the engine to secure ADR 80/03 certification, except for the addition of a crankcase breather and a passive diesel particulate filter (DPF) system. In addition, the engine software has been recalibrated to reduce emissions. The package also includes a Cat DPF monitoring system that continuously monitors backpressure and exhaust temperatures.
The emissions solution does not require the use of EGR or SCR technology, a significant advantage for Cat trucks. A 95 percent-plus PM (particulate matter) reduction is achieved using well-proven dual DPFs with passive regeneration technology. In-country testing has demonstrated that passive regeneration is extremely effective at all loads and speeds, negating the need for a complex active regeneration system.
Extensive Testing Programme Confirms No Impact on Performance
The engine and emissions control system are being subjected to extensive dynamometer testing and thorough in-market on-roadtesting in a Cat CT630 prime mover. The on-road programme tested the C15 under typical working conditions on a range of routes in various environments throughout Australia. The combination weight of the CT630 test truck has been varied up to 68,000kg including B-double operations.
The testing confirmed that the exhaust system had no impact on engine performance, even under worst-case conditions for producing soot. These conditions included driving bobtail and empty-trailer running, in both heavy peak-hour traffic jams and stop-start conditions.
Test results also confirmed that no active regeneration is required for the system, as the dual DPFs clean themselves at about 240 degrees Celsius, far lower than the engine’s peak operating temperature of 600 degrees.
In addition, the C15 demonstrated excellent fuel economy, regularly achieving 40 litres per 100 km (2.5km/l) while pulling 42 tonne. Under these operating conditions, fuel consumption has been measured to be within 1% of the Cat C15.
