Overall, the Series 60 engine provides truckers with the best combination of fuel economy, performance, driver satisfaction, long life to overhaul, reliability, low cost of operation, ease of service, and residual value.

Since 1992, the Detroit Diesel Series 60® has been North America's most popular heavy-duty on-highway diesel engine. With its excellent fuel economy and highly reliable performance, the Series 60 has become the industry's workhorse. The 2007 version of the Series 60 continues this tradition while meeting all Federal and California diesel-engine emissions requirements.

Tightening Emission Standards

The EPA has been reducing diesel emissions for the past 30 years. The 2007 regulations demand changes in both fuel and engine technology. The new regulations dramatically reduce nitrogen oxide (NOx) by 55 percent and particulate matter (soot and ash) by 90 percent. We achieved the first target by optimizing the existing Exhaust Gas Recirculation (EGR) system and the second by adding an Aftertreatment System, comprised of a Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF).

Exhaust Gas Recirculation (EGR)

Exhaust gas recirculation systems have been optimized to dramatically cut NOx formation by routing a measured amount of exhaust flow to the cylinders to lower combustion temperatures. The newly designed system features a highcapacity, tube-and-shell EGR cooler that is more rugged than the previous model.

Because coolant is the system's lifeblood, the water pump has been enhancedfor greater output, and we changed to a partial-flow stream inside the EGR cooler.

The EGR valve, now located on the cool side of the engine is new as well, at least for the Series 60. Identical to that used on the MBE 4000, it is noteworthy for its demonstrated reliability.

SMART Fuel System®

The SMART Fuel System adds to the performance and cleanliness of the 2007 Series 60. Dual solenoid Electronic Unit Injectors provide exact fuel metering and enable independent injection pressure control. This system has multiple injection capability to maintain performance and fuel economy advantages while at the same time improving engine sound quality.

Detroit Diesel Electronic Control (DDEC) VI

The Series 60 set the benchmark as the first fully electronic heavy-duty diesel engine. Now Detroit Diesel has raised the bar with the sixth generation DDEC VI engine management system. It employs a more powerful microprocessor, increased memory and enhanced diagnostics. The DDEC VI is capable of monitoring and managing all engine functions including the Aftertreatment Systems required for 2007 emissions. DDEC VI is a key part of the strategy to achieve greater operating efficiency and cleaner exhaust emissions.

Electronic Variable Geometry Turbocharger (VGT)

Engine performance starts with low-end throttle response. The new Series 60 uses an electronic variable geometry turbocharger that automatically - and precisely - adjusts its boost across the operating range, delivering quick and punchy lift on the low end, where turbo lag would otherwise occur.

Cylinder Kits

New pistons for the Series 60 are designed to improve combustion and oil control. Designed with enhanced monotherm geometry, the pistons have a new bowl shape and enhanced oil consumption characteristics, combined with a smoother liner bore finish. Together, these elements substantially reduce the amount of make-up oil required between oil changes.

Maintenance-Free Crankcase Breather Oil Separator

This device, a centrifugal oil separator, also helps reduce oil consumption. The spinning separator sends oil droplets back to the sump where they can continue to serve the engine. And the best thing is there is no maintenance required.
