PEORIA, Ill. — Caterpillar has announced the availability of its 15-litre CT15 engine in the CT660 vocational truck.

The CT15 rounds out the engine line, which currently consists of a CT11 and CT13 engine with 11 and 13 litres displacement respectively. The new offering can provide as much as 550 hp and 1,850 lb.-ft. of torque, the company says.

“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.”

The CT15 reaches peak torque at 2,100 rpm and pulls strong at low engine speeds, allowing for shifting at lower speeds when accelerating, according to the company.

It also features an engine brake rated at more than 600 bhp, helping drivers maintain optimum speeds down steep or long grades.

Based on a Navistar design, the CT15 uses exhaust gas recirculation (EGR) to eliminate NOx in-cylinder without requiring exhaust aftertreatment.

Cat says there’s a single electronic control module and fewer electrical connections to improve reliability and reduce maintenance time. For more info, visit www.DriveCat.com
