![]() ![]() To supply the air to the engine a Honeywell turbocharger makes 29 PSI of boost, this turbo utilizes electronically controlled vanes, and ball bearing technology to provide a quick spool up off the line. The intake system utilizes a dual intake runner manifold set up allowing them to use a swirl valve to change the length of the intake runner improving swirl effect throughout the entire RPM range, the swirl effect will allow for more efficient combustion within the cylinders. ![]() The injection system allows up to 10 injections per cycle, this will improve the combustion process resulting in a quieter operating system. This allows the LM2 to have a much higher power density than the other engines within the segment. The fuel system is all new and has the highest rail pressure compared to any of the other diesels in the segment, at 2,500 bar (36,350 psi) it allows for improved atomization of the fuel in the cylinders. The lower crank case is extended downward to provide further stiffness and strengthening the block. The pistons are also constructed from aluminum to keep the rotating mass down to keep the engine running efficiently. In order to keep the strength in the cylinder walls they have inserted a metal sleeve without sacrificing any weight the a cast iron block would add. The block for the LM2 has been constructed from aluminum along with the cylinder heads, this keeps the weight at a minimum. This diesel engine weights in at only 212 KG, only 5 more KG than the 5.3 liter gasoline option that is available. The inline six motor is inherently balanced, low friction, and low weight compared to some other engine architectures, all of these advantages result in a smoother, cleaner operating engine. The 3.0L Inline Six Duramax Turbo Diesel is a clean slate design from GM to separate themselves from the competition. They could choose from virtually any engine architecture they wanted, GM chose the inline six for the many efficiency advantages. For any future information we will be updating this product as much as we can, trying to keep you up to date. We will finally be entering the half-ton market but will remain exclusive to models that have a Duramax Diesel engine, some suspension and steering parts may fit on other applications but we will focus solely on the Duramax Diesel models in order to offer our loyal customers the best experience possible with our vast knowledge on every Duramax Diesel Truck. Another good thing is that it appears the DEF tank has finally been moved! No more filling the DEF front the engine bay but like other diesels, GM has finally moved it into the fuel door.ĭmaxStore will carry parts for this Duramax as soon as we can. The new engine will make 277 HP and 460 pound feet of torque, this is the most powerful diesel engine in the half ton trucks, beating out Fords 3.0 V-6 which makes 250 HP and only 440 pond feet. The GM Products chief, Mark Reuss, stated that the now Duramax will be class leading. ![]() So far all we know is that it will displace three liters and have an inline six configuration and will be mated to a 10 speed transmission. There has not been very many details released about the motor yet, we will keep you updated as we get more information. This is a huge step forward for GM to finally put a Duramax diesel motor into their half ton line up, something we have been asking for, for years. The Half-Ton is finally here! just revealed at the 2018 Detroit auto show is the new 3.0L inline 6 Turbo Diesel in the 2019 Chevrolet and GMC half ton trucks. ![]()
