LG4The LG4, or maybe Isuzu 6H, is often a commercial-grade automobile engine it is presently operating throughout above 300,000 Isuzu as well as GM-built trucks, such as the H-Series and also T-series vehicles. It can be mated to help the Allison 3000 and 3500 Series transmissions.The following trucks use the LG4:Chevrolet T-SeriesIsuzu F-SeriesIsuzu H-Series SpecificationsEngine type: 7,785cc (7.785L; 475.1cu in) I6 turboBore plus stroke: 115mm (4.53in) back button 125mm (4.92in)Block / Head: dull in terms of iron / hired ironRedline: 2400 rpmAspiration: Turbocharged & IntercooledValvetrain: OHC 4-VCompression: 16.0:1Common-railPower / Torque:??200bhp (150kW) @2200520lbft (705Nm) @1450??275bhp (205kW) @2200860lbft (1,166Nm) @1450LYA2009?-215bhp (160kW) @2200560lbft (759Nm) @1450LYB2009?-230bhp (170kW) @2200660lbft (895Nm) @1450LYC2009?-260bhp (190kW) @2200660lbft (895Nm) @1450LYD2009?-260bhp (190kW) @2200835lbft (1,132Nm) @1450LQF2009?-300bhp (220kW) @2200860lbft (1,166Nm) @1450Source: LB7The LB7 (engine computer code "1") had been first created in 2001 and also carried on until 2004. It is a 32-valve design and style along with high-pressure common-rail primary injection and also aluminum hot water tank heads. The most a problem concern considering the LB7 tend to be injectors intending bad. GM supplied a warranty for that in addition to currently injectors as well as warrantied for 7 years/200,000 miles. The Duramax was within the Ward's 10 Best Engines record in 2001 and also 2002.The next trucks utilize the LB7:Chevrolet Kodiak/GMC TopkickChevrolet Silverado/GMC Sierra HD SpecificationsEngine type: 6,599cc (6.599L; 402.7cu in) V8 turboBore x Stroke: 4.06in (103.1mm) x 3.90in (99.1mm)Block / Head: Cast gray straightener / Cast aluminumAspiration: Turbocharged & IntercooledValvetrain: OHV 4-VCompression: 17.5:1Injection: Direct; Bosch High Pressure Common-railPower / Torque: 300bhp (220kW) @ 3100rpm / 520lbft (705Nm) @1800 rpmSource: LLYThe LLY (internally called the actual 8GF1) (engine computer code "2") is a 6,599cc (6.599L; 402.7cu in) turbocharged engine which will debuted within 2004 along with continued right up until the final of 2005. It is usually a 32-valve style and design together with high-pressure common-rail primary treatment along with metal storage container heads. The LLY has been GM's first try to apply emissions specifications on their diesel trucks. To meet up with the following objective many people ventured into a freshly made Garrett turbocharger which has a variable geometry vane technique plus they put in a good Exhaust Gas Recirculation control device or maybe (EGR Valve). Learning coming from difficulties with injectors while in the prior LB7 GM evolved the control device insures permitting having access to the particular injectors and not having to get rid of the control device covers, preserving significant labour costs if injector substitute became necessary, and also stopping leaked supply from entering this crankcase, inducing oil dilution. Early on problems came forward from clients complaining with severe overheating, as well as in certain scenarios blown scalp gaskets. Initially GM denied who's had been your problem, but following the item was sued by the client group them relented and involved overheating plus lost brain gaskets as being a warranted item.The next vehicles utilized your LLY engine:2006 Hummer H1 AlphaChevrolet Silverado/GMC Sierra HD SpecificationsEngine type: 6,599cc (6.599L; 402.7cu in) V8 turboBore x Stroke: 4.06in (103.1mm) x 3.90in (99.1mm)Block / Head: Cast gray in terms of iron / Cast aluminumAspiration: Turbocharged & IntercooledValvetrain: OHV 4-VCompression: 17.5:1Injection: Bosch High Pressure Common-railPower / Torque: 310bhp (230kW) @3000rpm / 605lbft (820Nm) @1600 rpmHead casting is definitely 8gf1Block spreading is #22351021213Source: LLY/LBZThe 2006 LLY (engine code "2") debuted in the beginning regarding 2006 along with concluded production using the start off with the 3 years ago work schedule year. Mechanically it is similar into the LBZ and is particularly mated into the different 6 velocity Allison tranny on the other hand that retained the particular LLY designation.The LBZ (engine value "D") debuted while in the sooner a part of 2006 as well as continued in to 2007 offered just in the "classic" body style. It includes a better music packed in to the computer that lets the idea produce more power along with torque.Changes include:Cylinder stop spreading along with machining changes strengthen the end belonging to the hot water tank bores to guide elevated electricity and torqueUpgraded major keeping content raises durabilityRevised piston design and style helps cheaper data compresion proportion to be able to 16.8:1 from 17.5:1Piston pin bore diameter improved intended for greater strengthConnecting rod I sections is usually thicker for increased strengthCylinder scalps modified to accommodate lower compression as well as lessened cylinder firing pressureMaximum treatment pressure enhanced from 23,000psi (1,585.8bar) in order to over 26,000psi (1,792.6bar)Fuel supplied via higher-pressure pump, resource rails, submitting ranges and all-new, seven-hole resource injectorsFuel injectors bottle of spray right onto glow plugs, providing faster, better-quality starts off even more complete cold-start combustion regarding lowered emissionsImproved glow plugs temperature upward more rapidly as a result of an separate controllerRevised variable-geometry turbocharger is usually aerodynamically more efficient to assistance deliver even and fast reply and also lessen emissionsAir induction system re-tuned to further improve quietnessEGR includes greater chiller to help deliver extra exhaust to the systemFirst application involving new, 32-bit E35 controller, which adjusts and also compensates for any fuel movement that will strengthen proficiency plus cut down emissions"LBZ applications:Chevrolet Silverado HDChevrolet KodiakGMC Sierra HDGMC TopKickLLY applications:Chevrolet Silverado HDChevrolet KodiakGMC Sierra HDChevy Express full-size (reduced electricity productivity mated to some 4l80E transmission)GMC Savanna full-size (reduced electric power end product mated with a 4l80E transmission) SpecificationsEngine type: 6,599cc (6.599L; 402.7cu in) V8 turboBore x Stroke: 4.06in (103.1mm) x 3.90in (99.1mm)Block / Head: Cast overcast iron bars / Cast aluminumAspiration: Turbocharged & IntercooledValvetrain: OHV 4-VCompression: 16.8:1Injection: Bosch High Pressure Common-railPower / Torque:Redline (rpm)LBZ (Chevrolet Silverado 2500HD / 3500 Classic (auto trans), GMC Sierra 2500HD / 3500 Classic (auto trans))2006-2007360bhp (270kW) @3200650lbft (881Nm) @16003450LLY (Chevrolet Kodiak Medium Duty (LRX option), GMC TopKick Medium Duty (LRX option), Hummer H1 Alpha)2006-2007300bhp (220kW) @3000520lbft (705Nm) @16003200LLY (Chevrolet Kodiak Medium Duty (LPD option), GMC TopKick Medium Duty (LPD))2006-2007300bhp (220kW) @3000605lbft (820Nm) @16003200LLY (Chevrolet Express, GMC Savana)2006-2007250bhp (190kW) @3200460lbft (624Nm) @16003450Source: LMMThe LMM search engines are depending on the actual LBZ engines, but it surely had been developed for US EPA's 2007 emission standards, along with uses ultra-low sulfur diesel fuel, that went on purchase inside US in addition to Canada in the slip associated with 2006.New emission decline attributes comprise Diesel Particulate Filter (DPF). The DPF traps particulate matter, in addition to if the computer sensory faculties a force differential between a pair of sensors (one located upstream plus yet another downstream on the DPF) the actual pickup truck gets into a "regeneration" cycle. During this time around laptop computer commands the particular energy injectors for you to inject gasoline following your cylinder offers dismissed from your job forcing diet supply in to the DOC (Diesel Oxidizing Catalyst) where the fuel is burnt in order to increase your heat range belonging to the exhaust.
