Detroit 60 collection Engine Specs and also History

The Detroit 60 series diesel engine is among only a grasp of quintessential engine families that have earned widespread praise in lot of industries, including the class 7 and 8 on-highway segment. The engine is known to display a mix of respectable fuel economy and also performance in enhancement to fairly low emissions. Originally developed in 11.1 and also 12.7 liter variations, the well-known 14.0L Detroit 60 collection was introduced for the 2001 model year to handle the hefty duty segment.

The Detroit 60 series engine platform was distinct in countless ways. Very first and foremost, Detroit basically pioneered the electronically controlled diesel engine segment through it"s 1987 model year 60 Series. This drive-by-wire device relied on an electronic manage module (ECM) and injector driver module in order come actuate electric solenoids on every individual fuel injector. This device paved the way for premium injection control, thus maximizing fuel economy and performance in enhancement to granting the vehicle various diagnostic features and also reduced emissions.

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

DDEC Injection regulate

The Detroit 60 collection engine family uses EUI (electronic unit injector) fuel injectors that room operated through the ECM (engine regulate module). The ECM processes assorted sensor inputs and also uses this details to regulate injector timing, pulse width (amount of fuel injected per injection event), and also injection pump press (injector feeding pressure). The device is called Detroit Diesel Electronic Control, or DDEC because that short. The DDEC mechanism was updated several times end the food of the 60 Series" production.

DDECI - The an initial generation DDEC system used one Electronic Distributor Unit (EDU) to actuate the injector solenoids. Injection occasions are commanded by the ECM, however physically brought 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 system and may have detailed improved reliability and diagnostic functions.

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

Each readjust of the DDEC device represented an development in emissions and also diagnostic capabilities, amongst other features. The DDEC likewise has the capacity to shut an engine down in the event of an emergency that may an outcome in serious engine damage, such as low/no oil pressure, excessive engine coolant temperature, and excessive oil temperature.

The EUI injectors are distinct in that they have actually the innate properties of both one electronic and also mechanical unit injector. When an injection pump provides pressurized fuel to every individual injector the is a camshaft moved plunger that produces the final injection pressure. Meanwhile, injection occasions are initiated by ECM controlled electric solenoids.
