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. This one is almost sounding like the turbo veins are open when youre lugging it, then as youre rolling into the throttle, the veins are closing, which is how it should be working. By installing a lift pump with extra filtration from FASS or Airdog you will extend the life of the injection pump and injectors by allowing only the purest fuel into the system, and by feeding a steady supply of low-pressure fuel into the injection pump, it can better focus on its main task of generating high-pressure fuel. Hi Steve, thanks for the question. Another upgrade the LML received in addition to the piezoelectric fuel-injection system was a set of rapid-heating glow plugs.

Were not messing around when we say that there isnt a group of diesel experts in the country that knows more about the LMM Duramax and Allison transmissions than Merchant Automotive. 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. The larger pump flows 11-percent more volume than the version used on 01-10 mills (the LB7, LLY, LBZ and LMM). People often ask what is the best lift pump for an LBZ, and truthfully ANY lift pump is better than none at all. In the shop for the third time today. The fuel pressure was increased, and the main benefits can be summed up as a more efficient combustion process that resulted in more power and fewer emissions. All rights reserved. Simply put, they can crack under pressure. Bioethanol Production Slideshare. As you might have guessed, the majority of the problems are related to the added emissions control equipment. The LBZ injector nozzle has seven holes for fuel to spray out of, but the LMM has six which means there are two opposed streams of fuel directly above the wrist pin area of the piston, which causes hot spots directly on top of the weakest area which can lead to cracking. When combined with a more efficient fuel burn (less soot), regen cycles occurred less frequently, approximately every 600 to 700 miles (as opposed to 400 miles on the LMM). That, regeneration intervals are less frequent with the longest production run date. 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. Once fuel is present then re tighten valve and start truck. Aside from the CP4.2 injection pump, LML Duramax was a reliable motor that could last 300,000 to 400,000 miles when properly maintained. Other changes came in the form of a higher-pressure Bosch . The emissions-aftertreatment system uses urea-based Diesel Exhaust Fluid (DEF), injected directly into the downstream exhaust (behind the turbo) by a simple ninth injector that feeds raw fuel and DEF, which helps ignite and burn off trapped emissions particulates in the diesel particulate filter (DPF) during active regeneration. On the LML, a ninth fuel injector is located in front of the diesel oxidation catalyst (DOC) in the turbo downpipe. The use of the CP4.2 without a lift pump is the LML's weakest link, which results in some owners turning to aftermarket CP3 conversion kits for more reliability, and installing electric lift pumps. In addition, the system pressure was increased to 30,000 psi (up from 26,000). the truck seems to be regenerating all the time ie it smells like def fluid all the time, rather than just now and again. Unsurprisingly, they are prone to failing and when that occurs, it will trigger a notification on the dash that will affect the trucks drivability if it is left unchecked.

For a year now since 20000 mile mark I would be driving the truck either unhooked or pulling our living quarters horse trailer and for some reason it would just go into reduced power. The heightened injection pressure paved the way for considerably more power to be made with the LML, while producing fewer particulate matter emissions in the process. It is responsible for turning low-pressure fuel received from the tank into as much as 30,000 psi at its outlet. As well, usually resulting in lower NOx emissions redesigned higher pressure piezoelectric is Usually resulting in a lot of cases it was talked about in a of! When it is hooked up to the computer, it says it is the mass air flow sensor. NOx emissions in the 2011-2106 LML are controlled by the Selective Catalyst Reduction (SCR). Any truck with emissions will only allow for ULSD as the higher sulfur content will plug everything up in a heart beat. At first you might think you can just swap out the pump for another and hit the road, but sadly this is not the case.

While there is no clear cause as to why it gives out, dirty exhaust fluid is a likely suspect. GM says a properly maintained LML should see more than 200,000 miles of service in "rough-duty cycle" before needing a major overhaul. Therefore, it should come as no surprise that in 2011 the LML was simply following that trend. For a better experience, please enable JavaScript in your browser before proceeding. I would also have to presume that the plug was reinstalled in the correct orientation. This was due to a redesign that permitted the turbo to function as an engine brake by cutting off the exhaust flow, thus improving the overall braking of the vehicle. 14 Chevy 2500HD 6.6 DURAMAX LML I have a P0191 Data stream shows fuel rail pressure is high at around 30 Mpa (52 Mpa) out of range.
