Nine Notable Improvements for the 2013 Cummins ISX15

Here are nine notable improvements that make 2013 ISX15-powered trucks more reliable and can help fleets and owner-operators save money.

  • Exhaust Gas Recirculation (EGR) system – The diffuser in the EGR cooler inlet has been upgraded, along with material enhancements, providing more even coolant distribution and significantly enhanced cooler reliability and durability.
  • VGT™ Turbocharger – The VGT turbo controller could be reprogrammed or reflashed, avoiding complete turbo replacement, to maintain compatibility with engine calibrations.
  • Heated crankcase breather – If your customers haul loads through higher altitudes or colder regions of the country, they’ll be pleased to hear about the addition of a crankcase heating element and improved insulation in the crankcase breather. Those items help eliminate the possibility of water vapor freezing inside the breather and restricting proper flow.
  • Single High-Capacity Electronic Control Module (ECM) – Cummins now utilizes a single higher-capacity ECM 2350 Electronic Control Module to control engine and aftertreatment functions. That simplifies installation and troubleshooting, as it optimizes performance and reliability of the total unit, from air intake to exhaust aftertreatment. And the single unit eliminates the need for an additional aftertreatment controller and associated wiring. Higher capacity allows it to control more functions, including turning the crankcase breather heating element on and off and dosing Diesel Exhaust Fluid (DEF).
  • Longer-lasting DEF filter – In 2013, a change was made in the DEF filter media used for 2010 and 2013 ISX15 engines as part of the Selective Catalytic Reduction (SCR) system. The more robust, higher-capacity element delivers improved filtering capability, and has extended the recommended service interval by 50 percent, from 200,000 miles (321,869 km) to 300,000 miles (482,803 km), which means more uptime for your customers.
  • No-maintenance hydrocarbon doser – The hydrocarbon doser on Cummins 2013 engines features a new design that eliminates the need for cleaning. Heavy-duty engines built from 2010 to 2013 can be retrofitted with the doser, which eliminates maintenance expenses and downtime, increasing vehicle productivity.
  • Increased Diesel Particulate Filter (DPF) reliability with fewer regeneration events – Preserving the integrity and performance of the aftertreatment is important for operational efficiency and residual value, so we have changed the DPF service interval, from 300,000 miles (482,803 km) to 200,000 miles (321,869 km). This allows ash removal for higher DPF efficiency throughout the engine life. For engines manufactured from 2010 through 2012, there’s a new ReCon DPF exchange program that allows the rapid swapping of the filter.
  • Longer oil drain and fuel filter change intervals – Customers with light or normal duty cycles can now run an additional 5,000 miles (8,000 km) between fuel filter changes. Oil drain intervals have also been extended by 5,000 miles (8,000 km) when Valvoline™ Premium Blue™ engine oil is used. Your customers will spend less time in the shop and more time on the road, making money.
  • Continuous Improvements – Ongoing improvements to the engine’s emissions control system that have enhanced and improved functionality are available in updated engine calibrations. As a result, customers are seeing fewer Check Engine light and performance-limiting events. Benefits include greater uptime, more on-time deliveries and increased customer satisfaction.
