Cat CT13 Engine will be available in Cat Trucks in 2012

The Cat CT13 has already been proven in Cat's North American lineup of vocational trucks, including the Cat CT660 vocational vehicle.
"The Cat CT13 engine is designed specifically to yield optimum horsepower/torque combinations that are critical in the Australian market, whilst optimising fuel consumption" Fulton said. "It also provides customers with the flexibility to match power and performance to specific applications and operating conditions."

With displacement of 12.5-litres, it provides peak horsepower at 475hp and peak torque of 1700Lb-ft - performance ratings that are comparable to many 15-litre engines.

"In fact, the Cat CT13's peak torque is achieved at 1,000 rpm - just over idle," Fulton said. "And it sustains at higher rpm, for a more responsive off-the-line driving experience. By providing peak torque at lower rpm, the Cat CT13 engine will enable Cat trucks customers to conserve on fuel."

The CT13 engine combines an advanced exhaust-gas-recirculation system with a high-pressure common-rail fuel system, precision intake-air management system and electronic controls to provide an optimum blend of high performance, low emissions and superior fuel economy.

The combination of dual, sequential turbochargers and a precise fuel injection system allows the Cat CT13 to develop peak torque at lower speeds, a characteristic that reduces shifting and also allows for shifting at significantly lower speeds.
