The new Cat®
CT15 Engine offers Cat CT660 Vocational Truck customers greater horsepower and
torque for solid performance in demanding applications. The CT15 joins the CT11
and CT13 as the third engine option for the versatile Cat CT660. The 15-liter
engine is available with as much as 550 horsepower and 1,850 lb -ft of torque, which will power the
Class 8 truck through heavy-hauling jobs and demanding terrain.
“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 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
1,200 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 driver.
The CT15 also
offers an engine brake rated at more than 600 bhp—for industry leading
performance. The engine brake helps drivers maintain optimum speeds down steep
or long grades without frequent use of the service brakes. Proper use optimizes
productivity and lowers maintenance costs.
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 is
designed for reliable operation. The single electronic control module and fewer
electrical connections enhance reliability and reduce diagnostic and
maintenance time. The high-quality, foam-molded wiring harness secures wires
and connections for increased reliability and durability. Internally, the
premium cam and rolling element valve train reduce friction and operational
loads for reliable operation, extended durability and peak engine efficiency.
Cat vocational truck engines are backed by the unmatched support of the North
America Cat dealer network with more than 400 service locations and 2,300
service bays across the U.S.
and Canada
