We invite you to get behind the wheel with us, it's certain to be an interesting drive. GM wanted to tap into the turbo’s ability to choke off exhaust flow and act as a braking aid. LML Duramax emissions included a new Selective catalytic reduction system. vstech Super Moderator. The latest version of the 6.6L Duramax requires advanced emissions equipment, including the use of diesel exhaust fluid injection, to reduce nitrogen oxide emission levels by 63 percent over LMM powered trucks. This allows the LML to exceed currently mandated federal emissions requirements and … By 2011, the Duramax lineup had already seen four major revisions, starting out with the LB7 in ‘01, moving to the LLY in ’04½, the LBZ in ‘06 and the LMM in ‘07½. With increased horsepower comes increased heat and cooling demands. These Denso G4S Gen III injectors can support up to seven fuel delivery events per combustion cycle. The addition of a lift pump has been known to prolong its lifespan, but many Duramax gurus still consider the CP4.2 a ticking time bomb. In order to meet ever-increasing emission standards and keep up with the Joneses (at the time, Ford’s upcoming 6.7L Power Stroke), GM amended the Duramax once more for the 2011 model year. Specifications. The L5P Duramax’s injectors are solenoid injectors, instead of piezoelectric ones like those that are found on the LML Duramax. You're looking for the same thing I was, healthy engine … Put a fass 150 lift pump on. Ppei tuning These injectors are less complex, but because of their advanced technology, they offer performance similar to piezo-style units. In 2011, federal emissions regulations had tightened, so additional measures had to be taken to keep the Duramax compliant, so the LML was the first to be equipped with Selective Catalyst Reduction (or SCR), a system which used a urea-based exhaust fluid to break down harmful nitrogen oxides. Engine Design: 6.6L 90-Degree V8 Turbocharged Diesel. User account menu. In any case, we wanted to help our readers understand LML Duramax emissions. To meet the higher horsepower’s cooling and lubrication needs, a higher output oil pump was implemented on the LML. Get Efi Live.

Unlike the CP3 before it, the CP4.2 is precisely timed to both the camshaft and crankshaft position. That's my biggest fear is getting something that will … The LML Duramax is equipped with a SCR system that requires the use of DEF (diesel exhaust fluid). • If the DEF system detects that it requires service, a "SERVICE EXHAUST FLUID SYSTEM" notification will be displayed on the instrument panel. • Diesel particulate filter (DPF) nearly eliminates emissions of diesel soot. So i have recently got back into the Duramax game (about 4 years ago ) from having a slightly modified LB7. A version was used in the Trident Iceni. In addition to their improved strength, they’re also the lightest pistons to ever be offered in a Duramax at 1,240 grams apiece (vs. 1,272 g on the LB7/LLY and 1,349 g on the LBZ/LMM). K&N air intake, 4” exhaust. Source: GM Powertrain Division, www.gmpowertrain.com. year=now.getFullYear(); Over the engine’s lifespan it has gone through 6 different engine variations: LB7, LLY, LBZ, LMM, LML, and L5P. Top Contributors this Month … Here is everything you need to know! Many of these emissions devices are problematic in LML model years (2011-2012). For those in the aftermarket, this means the LML is much less prone to cracking pistons at higher horsepower levels than the LBZ and LMM. Continue on to reading this issue and look for links to the latest issues, straight to your inbox, as soon as they’re released! Active regeneration programming cleans the DPF periodically (estimated regen period every 700 miles, 300 miles less then previous systems, under normal operating conditions) by injecting diesel fuel into the exhaust stream via a "downstream injector", completely burning off soot captured in the DPF. The implementation of the SCR system, which requires a constant supply of diesel exhaust fluid (DEF), was met with heavy scrutiny. Imagine driving a brand new Duramax with twice the factory horsepower. The LML Duramax was the power house for almost six years(2011-2016) when the L5P was released in 2017. Give your engine the fueling it needs with a dual pump kit from ATS! @Durrrrtymax | @EnthuzstApparel Like Us On Facebook! That year, Ford, Dodge and GM all released engines designed to meet the new particulate matter (PM) and nitrogen oxide (NOx) limits mandated by the Environmental Protection Agency. Manufactured Years: 2006-2007. This allows the LML to exceed currently mandated federal emissions requirements and potentially meet future requirements as well. Mobile application that interacts flawlessly with your car. A DEF tank will need to be filled approx. This is opposed to the previous generation's (LML) late/post injection technique. He started Pure Addiction Diesel Performance in 2013 and has been building diesel trucks and engines ever since, just like this 6.6L LML Duramax that puts out 1,200 hp! The fifth generation common-rail V8 was given the RPO code LML. • If the DEF fluid level is depleted, an "EXHAUST FLUID EMPTY" notification will be displayed on the instrument panel. Been very happy with it. Your first start will be is getting a cp3 conversion to take the place of the LML cp4. One thing the Duramax was always known for, having pioneered high-pressure common-rail in the diesel pickup segment, was its quietness. The initial engine was produced in Moraine, Ohio, on July 17, 2000. Best duramax years - worst to lookout for. While the LML seemed to be the “best” duramax to date there has been a serious disturbance since the release of the L5P. • Selective catalyst reduction (SCR) utilizing diesel exhaust fluid injection (DEF). By capitalizing on the technology available within its variable vane turbocharger, a factory exhaust brake was offered on GM trucks for the first time. Chevrolet Introduces 2021 Silverado HD Carhartt Special Edition, Built Like an Anvil: How to Piece Together an Indestructible Duramax, Yes, I would like to receive emails from Nitto Tire and Driving Line, I’d like to receive Driving Line’s twice-monthly eNewsletter, Sign me up for a quarterly digital magazine subscription, OHV, four valves per cylinder, single cam, Bosch high-pressure common-rail, direct injection, Cast-aluminum with six 14mm diameter head bolts per cylinder (with sharing). The Duramax … BrennanK Super Moderator. One group supports it because deleting emissions equipment prevents costly repairs, improves mileage, and increases power. I told myself i was not going to delete the LML and leave it stock but i think we all know how that goes. Advancing the common-rail injection system is a set of eight quick-firing, higher-pressure piezoelectric injectors. It is a 32-valve design with high-pressure common-rail direct injection and an experimental composite design cylinder head. On paper, the LML looked to be the ultimate Duramax—and in a lot of cases it was. Looking to buy a new truck. I got a good one I think. The delete debate will never end. Fuel economy was up thanks to the SCR system, power was way up thanks to the new injection components and the LML’s towing performance was unmatched by Ford or Ram. Travis Turner discovered there wasn’t anyone in his area working on diesels, or anyone who really knew much about them, so he set out to change that. Find out what went into this diesel build. DEF is injected into the exhaust stream where a chemical reaction occurs that reduces NOx emissions. The Duramax LML introduced the "9th injector" system in order to supply fuel to the DPF during regeneration. Failure to have the system serviced within 200 miles will result in speed limited to 55 mph upon the next startup, and 4 mph on the next refuel. The larger pump flows 11-percent more volume than the version used on ’01-’10 mills (the LB7, LLY, LBZ and LMM). Loved them. Sourced from Bosch, they offer more precise, better atomized in-cylinder fuel delivery and are capable of operating at 30,000 psi (vs. 26,000 psi on the LMM that preceded it). Engine will enter into a limp-mode if DEF tank is empty. Log in sign up. If the tank remains empty, speed will be limited to 4 mph after the second refueling. Also incl… Thanks to the beefier pistons, rods comparable in strength to the LBZ/LMM mills and a lighter overall rotating assembly, stock bottom end LMLs are known to hold up to 700rwhp without issue. The LML is a further improvement upon the LMM. If you recall, GM and Isuzu partnered up on the Duramax project in the late ‘90s, and it’s a cordial relationship that still survives today. • If the DEF fluid quality is detected to be low, an "EXHAUST FLUID QUALITY POOR" notification will be displayed on the instrument panel. Repeated NOx sensor prompted GM to make changes to the sensors and issue a 10 year, 110,000 mile warranty on the updated sensor. Close. Live lorry diagnostics and also troubleshooting. The factory CP4 injection pump found on the LML Duramax cannot support any fueling above stock. Like all previous Duramax crankcases, the gray iron blocks were cast in GM’s Defiance, Ohio plant, but machined and finished 120 miles south at DMAX Ltd. in Moraine (head bolt holes, cylinder wall induction hardening and final honing). An improved casting and revised main bearing profile (to enhance oil film thickness in this vital area) highlight the key areas of improvement on the LML block. Chevrolet/GMC- 2011-2016 LML Duramax – Includes Song Files. However, this technology actually allows for an advantageous engine calibration to be executed, reducing the duty cycle of DPF regenerations and providing significant improvements in fuel economy.

LML Duramax – Photo from Chevrolet Media LML Duramax Service Schedule: Normal Conditions. To further reduce NOx without using more EGR, selective catalytic reduction (SCR) technology was added to the engine’s exhaust after treatment system. 6.6 Duramax: LML. The LML was replaced for the 2017 model year by the next generation Duramax L5P. The DEF tank is approximately 5 gallons (18.9 liters). The concern seems to have been addressed appropriately and 2012+ MY Duramax LMLs should not experience repeated issues. After 200 miles of driving with poor quality DEF, the truck will be speed limited to 55 mph. Failure of this CP4 pump is usually catastrophic, causing instant contamination of the entire fuel system with metal particulates. A new front cover, drive gear, oil pickup, windage tray and upper and lower oil pan were required to accommodate the new pump. GM's official statement is that fuel mileage increased 11% over the previous generation LMM engine. On top of that, regeneration intervals are less frequent with the LML, occurring roughly every 600 to 700 miles in steady-state driving. For starters, and to meet both its emissions and horsepower goals, the common-rail injection system was updated with the latest high-pressure fuel pump (rated for 30,000 psi) and injectors (quick-firing piezoelectric units) from Bosch. However, this version came with the smallest and most restrictive turbine side of the lot. We've received reports of similar problems with some 2012 MY pickups (all of which were repaired under warranty), but with nowhere near the frequency of 2011 MY engines. Duramax Maintenance Schedule & Service Information. It receives its fuel from the aforementioned CP4.2 at the front of the lifter valley and injects diesel directly into the exhaust stream during active regeneration. Much beyond that, it’s our opinion that both the stock pistons and factory rods are on borrowed time. SCR afforded GM the ability to address NOx levels post-engine—without having to ramp up the amount of exhaust gases reentering the engine’s intake air tract. A concerned Ford quickly acted to increase the Power Stroke's available horsepower and torque rating, issuing a free performance upgrade to owners which would re-calibrate the engine to the tune of 400 horsepower and 800 lb-ft.

Duramax History, Lesson 4: LMM. … DuramaxHub.com, all rights reserved. DEF is not particularly costly and owners incur noticeable fuel savings even while factoring in the cost of exhaust fluid. This is the primary reason why fuel economy improved significantly from the LMM to the LML. Although emissions are necessary on diesel trucks today, they frequently cause issues, especially when they are first released. We go into more detail about those issues in our “LML Duramax problems” page. Called an exhaust brake but technically a turbo brake, this new technology debuted at the perfect time, as GM had just treated its ‘11 model HDs to a fully boxed frame, larger leaf springs, a stouter front suspension and fittingly increased its trucks’ towing and hauling capacities. The LML Duramax was released for 2011 model General Motors & Chevrolet HD trucks. • Exhaust gas recirculation (EGR) with EGR cooler. 18.7M views. Subsequent warnings will follow. General Motors blindsided Ford with the release of these figures, which were revealed shortly after Ford's 390 hp/735 lb-ft 6.7L Power Stroke became available. document.write(year); I did the EGR cooler delete (it's a pain in the ass), 4 inch straight pipe with a AutoCal tuner from MotorOps. At 1,130 g apiece, they’re even lighter than the rods used in the LB7.
