Cat CT660 Gets A Boost


Cat CT15 Boosts CT660 EngineCAT customers now have another option on the CT660 engine.  The CT15 joins the CT11 and CT13 and offers greater horsepower and torque.  The 15-liter engine is available with as much as 550hp and 1,850 lb.-ft of torque.

The CT15 Engine is the perfect power solution for heavy-duty applications and extreme environments, said George Taylor, Director of the Caterpillar Global On-Highway Truck Group. Cat Vocational Truck customers can count on the CT15 for years of reliable, durable operation, which translates into a longer-lasting truck and higher resale value.

According to a Cat press release, the CT15 is built for reliability.  The CT15 has a single electronic control module and fewer electrical connections, which enhances reliability and reduces diagnostic and maintenance time. 

“Like the CT11 and CT13, the Cat CT15 Engine features advanced emissions control technology that helps keep truck weight down and simplifies maintenance. The EGR system reduces NOx in-cylinder without requiring diesel emission fluid. The design eliminates the emission fluid costs and associated maintenance time, and it effectively increases the payload capacity of the truck.

“The CT15 core is a proven block and crankshaft with billions of miles of operation in demanding truck applications. The dual sequential turbochargers and precisely controlled high-pressure common-rail fuel system enable the CT15 to reach peak torque at 2,100 rpm.  The strong pulling power at low engine speeds allows for shifting at lower speeds when accelerating and reduces the need for shifting when powering up steep grades. Interstage cooling between turbochargers increases air density to maintain power as speeds increase. The result is enhanced productivity and less wear and tear on the truck and drive,” the press release states.

Caterpillar has been in business for more than 85 years and is the world’s leading manufacturer of mining, construction, diesel and natural gas engines, industrial gas turbines and diesel-electric locomotives.
