Detroit Diesel - DD13


Save Fuel, Maintain Power

IMG 0649

     The Detroit DD13 engine’s smart design makes the most of every gallon by integrating groundbreaking, fuel-efficient technologies:


    • Amplified Common Rail System (ACRS™) optimizes each injection event
    • Advanced time-based cooling system decreases fan usage
    • Strong pull down to 1100 RPM offers a fuel economy “sweet spot”


Keep Running

     With the longest service intervals in its class and an easily serviceable design, the Detroit DD13 lowers your cost of ownership by decreasing your time in the shop. With oil, fuel and coolant filters positioned above the frame rails, you’ll be back in the driver’s seat fast. If maintenance issues come up on the road, you can count on Detroit Virtual Technician™ on board diagnostics system to let you know how serious the fault code is, where the nearest part you need is located, and when you can get into the next available service bay, and then it can even schedule your repair appointment for you.


Extensive Parts Availability

Sharing common service operations and 65% of its parts with the DD15® and DD16® ensures that trained technicians are ready to serve you and your DD13 at any of our 800+ authorized Detroit locations across the highways and back roads of North America.


Perform When It Counts

     Driving the DD13 diesel engine means having power and torque when you need it.  The robust DD13 extends our track record of durable engines with a B50 life of 1 million miles. Its asymmetrical turbocharger has fewer moving parts than the competitor’s VGT or waste-gated turbocharger.


Other key performance features include:

    • Integrated Jacobs® Engine Brake
    • Ribbed cast iron block that lowers Noise Vibration Harshness (NVH)
    • Robust rear gear train
    • Boosted Fuel Economy with BlueTec® Emissions Technology


     Like all current EPA Detroit engines, the DD13 comes with BlueTec® SCR and our exclusive 1-Box Configuration, providing up to a 5% improvement in fuel economy over similarly spec’d EPA 2013 engines.
