Duramax Engines: A Short Background
A Duramax engine is a line of diesel engines designed and manufactured by General Motors and Isuzu.
These engines are known for their high performance and reliability, making them a popular for pickup trucks and other heavy-duty vehicles, such as the Chevrolet Silverado and GMC Sierra. These engines are also in various other GM vehicles, including vans and SUVs.
The first generation of Duramax engines, introduced in 2001, was known as the LB7. This engine had a displacement of 6.6 liters and was rated at 235 horsepower and 500 lb-ft of torque.
The second generation, introduced in 2004, was known as the LLY. This engine featured improved injectors and a variable geometry turbocharger, which helped to boost its output to 310 horsepower and 605 lb-ft of torque.
In 2006, General Motors introduced the LBZ, which was an upgraded version of the LLY engine. This engine featured several improvements, including a larger turbocharger and a stronger block, which allowed it to produce up to 360 horsepower and 650 lb-ft of torque.
The LMM Duramax engine was introduced in 2007 and featured a diesel particulate filter (DPF) to meet new emissions regulations. This engine produced up to 365 horsepower and 660 lb-ft of torque.
The current generation of Duramax engines, introduced in 2011, is the LML. This engine features several improvements over previous generations, including an even stronger block and cylinder heads, improved injectors, and a more efficient turbocharger. The LML engine produces up to 397 horsepower and 765 lb-ft of torque.
