The Caterpillar CT660 vocational truck offers a powerful engine option with the CT15. This 15-liter engine delivers up to 550 horsepower and 1,850 lb-ft of torque, making it ideal for demanding applications. Built on the proven C15 platform, the CT15 boasts durability and advanced technologies for optimal performance and efficiency.
Cat CT660 Engine: The CT15 in Detail
The CT15 engine utilizes the robust C15 block, crankshaft, and other core components known for their long-lasting performance. Cat engineers incorporated dual sequential turbochargers with interstage cooling to maximize air density and power output across the engine’s RPM range. This design ensures impressive acceleration and the ability to conquer steep grades. A high-pressure common-rail fuel injection system precisely manages fuel delivery for optimal torque and responsiveness in various operating conditions.
The 15-liter engine is available with as much as 550 horsepower and 1,850 lb ft of torque.
Internal Components Designed for Efficiency and Reliability
Internally, the CT15 engine features a premium cam and rolling element valve train that minimize friction and operational loads. These components contribute to the engine’s overall reliability, longevity, and fuel efficiency. Furthermore, the CT15 utilizes a single electronic control module and a simplified wiring harness. This design reduces the number of electrical connections, leading to quicker diagnostics and less maintenance downtime. The high-quality, foam-molded harness also enhances reliability and durability by securely protecting wires and connections.
Enhanced Braking and Emission Control
The Cat Ct660 Engine offers an optional engine brake capable of producing over 600 bhp. This powerful braking system assists drivers in maintaining safe speeds on descents, reducing the need for frequent service brake application. Utilizing the engine brake promotes productivity and extends the life of the service brakes, ultimately lowering maintenance expenses.
Like the CT11 and CT13, the CT15 incorporates advanced emissions control technology. The Exhaust Gas Recirculation (EGR) system effectively reduces NOx emissions within the combustion chamber without requiring Diesel Emission Fluid (DEF). This design eliminates DEF costs and associated maintenance while maximizing payload capacity.
Support and Availability
Cat vocational truck engines are supported by an extensive network of dealerships across North America. With over 400 service locations and 2,300 service bays, Cat ensures prompt and efficient maintenance and repair services. George Taylor, director of the Caterpillar Global On-Highway Truck Group, emphasized the CT15’s robust design and suitability for heavy-duty applications and challenging environments. He highlighted the engine’s contribution to increased truck longevity and higher resale value.
The CT15 engine provides a powerful and reliable solution for the Cat CT660. Its advanced technologies and durable construction make it a valuable asset for vocational truck operators seeking optimal performance and efficiency in demanding applications.
