Duramax 

It is known that the Duramax engine was developed by the engineers of the Italian company VM Motori S.p.A., whose logo flaunts on the front cover, with the work done by GM engineers. VMM manufactures engines for various purposes: automotive, industrial, marine and power generators. Range Rover, Jeep, GM cars were equipped with VM Motori engines at different times.

 

Until 2007, VM Motori belonged to the American company Penske Automotive. In 2007, GM bought a 50% stake from Penske Automotive and they owned the company in equal 50/50% until Penske Automotive sold its 50% stake to Fiat in 2011. This move led to the fact that in 2013 GM sold its stake to VM and now the company is 100% owned by Fiat. In the sale of its shares, GM retained the rights to manufacture a number of engines, which were jointly developed by VM Motori and GM, incl. 2.8 turbodiesel VM A428. Re-drinking of this story is outlined in a post on the idparts blog.

 

The Duramax 2.8L SHTB2 engine traces its ancestry to the VM R 428 DOHC, which, in turn, was developed on the basis of the R 425 DOHC engine, the volume of which was increased to 2.8 liters (2766 cm3) and the index was changed.

The VM R 428 DOHC engine was installed on the Chrysler Voyager (2001-2007), Jeep Cherokee (2001-2004), Jeep Liberty (2001-2006), BMC Megastar (since 2004) and what is especially interesting on the Chevrolet Colorado & Holden Colorado & Nova S10 (Brazil) (2012-2013)

The VM RA 428 DOHC engines are a development of the R 428 DOHC and the basis for the Chinese licensed SDEC SC28R engines. Installed on Jeep Liberty (2008-2010), Jeep Wrangler (2007-2010), Dodge Nitro (2007-2010), Chrysler Grand Voyager (2008-2011) and is installed on Maxus / LDV T60 trucks (since 2016)

The VM A 428 DOHC engines are an evolutionary continuation of the R428 DOHC with 1,800 bar (26,000 psi) common rail injection system and piezoelectric injectors. Installed on Jeep Cherokee (2010-2012), Jeep Wrangler (2010-2018), Chrysler Grand Voyager / Lancia Voyager (2011-2013), Chrysler Grand Voyager / Lancia Voyager (2013-2016), and installed on Holden Colorado, Holden Colorado 7 power (from 2013), Holden Colorado, Chevrolet Colorado (from 2014) Chevrolet Express (from 2017-present).

Currently, VM Motori is disowning our engine, because despite the VM logo under the hood, GM engineers changed the attachment.

 

Duramax engines were manufactured at a plant in Rayong, Thailand. Despite GM's planned withdrawal from Thailand and the sale of the plant, engine supplies will continue, although there will be delays in the supply of diesels for the 2021 model year.

According to the latest information, in the future, 2.8L Duramax engines will be produced at the GM Flint Engine plant in Flint, Michigan, USA. and the fact that GM Defense's Duramax 2.8 Infantry Squad Vehicle (ISV) lightweight all-terrain vehicles were recently purchased by the US Department of Defense.

Colorado duramax

The American civilian pickup Chevy Colorado has a Duramax 2.8L LWN engine, which differs from the XLD28 version by the absence of a preheater and a different belt passage.

 

DURAMAX 2.8L LWN turbo diesel engine

The Duramax 2.8L engine is one of the cleanest diesel engines ever produced by General Motors, and meets some of the most stringent American emission standards, incl. thanks to the cooled exhaust gas recirculation (EGR) system.

The engine belongs to the international family of GM 4-cylinder turbo diesel engines and features a variable geometry turbocharger for optimal power and efficiency across the entire rpm range and a balance shaft for smooth operation.

The wide torque range makes the 2.8L Duramax very powerful at low rpm, while the turbine gives a sense of confidence by instantly and evenly increasing power when needed.
