Detroit 60 series Engine Specs and also History

The Detroit 60 series diesel engine is just one of only a grasp of quintessential engine family members that have earned extensive praise in lot of industries, consisting of the class 7 and 8 on-highway segment. The engine is known to display screen a mix of respectable fuel economy and performance in enhancement to reasonably low emissions. Originally created in 11.1 and also 12.7 liter variations, the famous 14.0L Detroit 60 collection was introduced for the 2001 version year to tackle the hefty duty segment.

The Detroit 60 series engine platform was distinctive in plenty of ways. First and foremost, Detroit essentially pioneered the electronically managed diesel engine segment through it"s 1987 design year 60 Series. This drive-by-wire device relied on an electronic regulate module (ECM) and also injector driver module in order come actuate electrical solenoids on every individual fuel injector. This mechanism paved the means for remarkable injection control, for this reason maximizing fuel economy and also performance in enhancement to providing the auto various diagnostic features and also reduced emissions.

Furthermore, the Detroit 60 series features a solitary overhead camshaft to operate its intake valves, exhaust valves, and fuel injector plungers. One might argue the the Detroit 60 series was somewhat ahead of its time, but it did not experience reliability/longevity involves often associated with new, unproven concepts.

An enhanced engine block was presented after November 30th, 1994; engines with serial number 6R210293 and later feature this engine block design. A more far-reaching engine block improvement was presented May 2nd, 1998 and is discovered in engines v serial number 6R408505 and also later. This new design presented a new lubrication circuit i m sorry granted the use of piston cooling jets.

DDEC Injection regulate

The Detroit 60 collection engine family members uses EUI (electronic unit injector) fuel injectors that space operated by the ECM (engine manage module). The ECM processes various sensor inputs and uses this information to regulate injector timing, pulse width (amount that fuel injected per injection event), and injection pump push (injector feeding pressure). The system is called Detroit Diesel Electronic Control, or DDEC because that short. The DDEC mechanism was updated numerous times over the course of the 60 Series" production.

DDECI - The very first generation DDEC device used one Electronic Distributor Unit (EDU) to actuate the injector solenoids. Injection occasions are commanded by the ECM, yet physically carried out by the EDU.

DDECII - The second generation DDEC system got rid of the EDU and also instead the ECM picked up the job of actuating the injector solenoids. This streamlined the engines computer system and also may have noted improved reliability and diagnostic functions.

DDECIII & DDECIV - third and fourth generation DDEC systems increased diagnostic capabilities and introduced the Diagnostic Data Reader (DDR) function.

Each adjust of the DDEC system represented an development in emissions and diagnostic capabilities, amongst other features. The DDEC additionally has the capacity to closeup of the door an engine under in the event of an emergency that may result in significant engine damage, such as low/no oil pressure, too much engine coolant temperature, and also excessive oil temperature.

The EUI injectors are distinct in the they have the natural properties the both an electronic and also mechanical unit injector. If an injection pump provides pressurized fuel to each individual injector that is a camshaft driven plunger the produces the final injection pressure. Meanwhile, injection events are initiated through ECM controlled electric solenoids.
