The Duramax V8 engine is a family of 6.6 cubic decimeter Diesel engine V8 engines produced by DMAX, a cosignatory venture between General Motors and Isuzu in Moraine, Ohio. The Duramax stoppage and heads are poured at The Defiance GM Powertrain metalworks in Defiance County, OH. This engine was initially installed in 2001 Chevrolet and GMC trucks, and has since become an option in pickups, vans, and medium-tariff trucks. In 2006, output at Moraine was reportedly limited to approximately 200,000 engines annually.[1] On May 9, 2007, DMAX announced the output of the 1,000,000th Duramax V8 at its Moraine facility,[1] followed by the 2,000,000th connected March 24, 2017.[2]
Engine RPO Codes [edit]
LB7 [redact]
RPO LB7 (locomotive computer code "1") was first introduced in 2001 and continued until early-2004. Information technology is a 32-valve aim with high-pressure informal-rail direct injectant and an experimental composite design piston chamber head.
The tailing trucks habit the LB7:
- Chevrolet Kodiak/GMC Topkick
- Chevrolet Silverado/GMC Scomberomorus sierra HD
Specifications [delete]
- Stop / Head: Cast Smoothing iron / Aluminum
- Compression: 17.5:1
- Injection: Direct; Jerom Bos high common-rail
- Power / Torsion: 300 HP (224 kW) at 3,100 rpm 520 lb⋅ft (705 N⋅m) at 1,800 rpm
The LLY was introduced in 2004 and replaced the LB7 completely mid-yr
LLY [edit]
The LLY (internally called the 8GF1) (locomotive code "2") is a 6.6 L; 403.9 copper in (6,619 cc) turbocharged engine which debuted in middle-2004 and continuing until the end of 2005. It is a 32-valve design with aggressive common-rail direct injection and aluminium cylinder heads. The LLY was Gramme's first attempt to implement emissions requirements along their diesel trucks. To meet this goal, they turned to a newly developed Garrett turbocharger with a variable geometry web system and installed an EGR Valve. Learning from problems with injectors in the previous LB7, GM changed the valve covers to allow access to the injectors without having to remove the valve covers, saving significant labor costs if injector replacement became necessary.
The undermentioned trucks used the LLY engine:
- 2006 Hummer H1 Alpha
- Chevrolet Silverado/GMC Sierra HD
Specifications [edit]
[3]
- Block / Head: Cast gray iron / Cast atomic number 13
- Compression: 17.5:1
- Injection: Bosch High Inferior-rail
- Power / Torque: 310 bhp (231 kW) at 3000 rpm / 590 lb⋅ft (800 N⋅m) at 1600 rpm
- Top dog casting is 8gf1
- Block casting is #22351021213
LLY/LBZ [edit]
In that location are two VIN codes for the LBZ. The first is VIN 2 produced in late 2005 and early 2006. The VIN 2 engine is mechanically and physically the aforementioned as the VIN D engine but utilizes LLY engine tuning due to the LBZ tuning pickings longer to be EPA registered and settled into production.
The second is VIN D. This was introduced in 2006 and continued into 2007 oversubscribed only in the "standard" torso style. IT has an improved engine computer tune that produces enlarged power and torsion ended the 2005 LLY translation of the engine. Entr of the Duramax in the Express/Savanna vans. The LBZ is one of the more desirable Duramax engines due to its speciality, reliableness, and organism pre-emissions (DPF appeared on the next generation LMM in 2007).
Changes include:
- Block casting and machining changes strengthen the bottom of the piston chamber bores to support augmented power and torque
- Upgraded main heraldic bearing material increases durability
- Revised piston design lowers densification ratio to 16.8:1 from 17.5:1
- Piston pin bore diameter increased for increased military posture
- Connecting rod " I " section is thicker for increased strength
- Cylinder heads altered to accommodate lower compression and reduced cylinder firing pressure
- Maximum injection pressure level increased from 23,000 pounds per square inch (1,585.8 bar) to more than 26,000 psi (1,792.6 bar)
- Fuel delivered via high-pressure pump, fuel rails, distribution lines and all-new, cardinal-hole fire injectors
- Fire injectors spray now onto luminescence plugs, providing faster, better-quality starts and more complete cool-start burning for reduced emissions
- Improved glow plugs heat up faster through an independent controller
- Amended variable-geometry turbocharger is aerodynamically more efficient to help deliver smooth and immediate response and lower emissions
- Air induction system re-tuned to enhance quietness
- EGR has larger cooler to bring more wipe out into the system
- First application of new, 32-snatch E35 restrainer, which adjusts and compensates for the fuel flow to bolster efficiency and reduce emissions
LBZ applications:
- Chevrolet Silverado HD
- Chevrolet Kodiak
- GMC Sierra HD
- GMC TopKick
LLY applications:
- Chevrolet Silverado HD
- Chevrolet Kodiak
- GMC Sierra HD
- Chevrolet Fast full-size (reduced power output mated to a 4L85E transmission)
- GMC Savana full-of-the-moon-size (reduced power output mated to a 4L85E transmission)

LGH [edit]
The 6.6L Duramax diesel engine (VIN code "L") is ill-used on 2010 interim and 2011 Chevrolet Express and GMC Savana vans and 2011 Chevrolet Silverado and GMC Sierra trucks with RPO ZW9 (chassis cabs or trucks with pickup box delete). The LGH engine is rated at 335 bhp (250 kW) at 3100 rpm and 685 lb⋅ft (929 N⋅m) at 1600 rpm. Related to the LML this locomotive also uses a DPF and DEF system to converge emanation standards.
LML [edit]
The 6.6L RPO LML (VIN code "8") is the 2011–2016 version of the Isuzu/GM Duramax V8 diesel. It is a further advanced version of the LMM engine with the majority of the changes addressing a required drastic simplification in locomotive emissions. Some mechanical aspects of the engine, such as piston oil flow design for improved temperature ascertain and oil pump design, were also better to enhance durability even further.
The LML locomotive was significantly updated for 2011 to provide built exhaust emissions that comply with the new federal emission standards for diesel engines, ply better locomotive rigidity and further noise reduction. New 29,000 PSI piezo injectors, a complete fuel system-hardening to digest up to 20% biodiesel mixtures and urea injection (to keep down nitrogen oxides) with a 5.3 gallon urea tank are updating the fuel and emissions systems. This engine has a fire injector in the deplete tract, to tolerate peeled fire injection during the particulate filter recycling routine. The RPO LML engine is rated at 397 horsepower (296 kW) at 3000 rpm and 765 lb⋅ft (1,037 N⋅m) of torsion at 1600 rpm.[9]
L5P [edit]
The L5P duramax is the latest translation of the Duramax V8 diesel engine.(locomotive code Y) Introduced in the 2017 model year it is the most powerful diesel pickup truck railway locomotive GM has produced with 445 H.P. (332 kW) at 2,800 rpm and 910 lb⋅ft (1,234 N⋅m) at 1,600 rpm. Innovation spec performance can exceed 550 bhp (410 kW) at 3050 rpm and 1,050 lb⋅ft (1,424 N⋅m) at 1975 rpm.
L5D [edit]
The L5D Duramax is a downrated version of the L5P for the Harry Silverado MD and Internationalist CV trucks (Class 4,5,6). The L5D was downrated to increase reliability and reduce downtime. The L5D was introduced in 2018 for the 2019 theoretical account year Chevy Silverado Physician and Transnational CV trucks. Specifications for the L5D are 350 hp (261 kW) at 2600 Revolutions per minute and 700 pound⋅foot (949 N⋅m) at 1600 Revolutions per minute.
