Duramax

In 2007 General Motors incorporated into the Duramax engine a variety of innovative engineering and technologies including Combustion control with closed crankcase aeration; Turbocharging variable-geometry system; Enhanced Exhaust Gas Recirculation (EGR); Exhaust control with new Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC); and Enhanced air induction system for noise reduction. This technological tour de force made the 2007 Duramax one of the finest engines of that model year, gasoline or diesel.

State Of The Art Diesel Duramax

In order to meet new emission regulations in 2007, the Diesel Duramax LMM 6600 diesel engine has risen to the occasion while remaining the leader in torque and power through an extensive redesign. While plenty of torque and power are good things, the new Diesel Duramax Particulate Filter and exhaust catalyst have increased the cost of this engine by approximately $2700 which showed up in the sticker price of the Duramax based truck in the GM dealership floors.

Duramax Diesel Runs On Low Sulfur Fuel

The Duramax Diesel for this model year onwards also requires the use of CJ-4 API certified motor oil and Ultra Low Sulfur Diesel fuel. This usually computes to a higher ticket price at the dealership, however some dealers offer a rebate or incentive to minimize the additional cost to Duramax Diesel owners.

Duramax Fuel Injectors Are All New

These newest Duramax Fuel injectors have 6 spray valves in each tip for enhanced fuel vaporization. Solenoid-style Duramax injectors lessen potential fuel leakage in between pulses. They also allow more accurate fuel control while offering dependable performance amid hot-fuel conditions in the Duramax. This largely reduces the possibility of clogging caused by fuel contamination in the Duramax. In order for the E35 engine control module to accurately match the flow requirements of each particular Duramax engine, the injectors are coded and installed straight into the head. This also allows the ECM to make up for small variations and ensure precise Duramax Fuel delivery.

Chevy Duramax Is Ecologically Smart

The diesel particulate filter in the Chevy Duramax employs a twofold DOC-DPF design with dynamic regeneration. According to GM, the regeneration method is activated automatically and uses heat to burn up the soot. A built-in Duramax computer module controls the oxygen content and fuel injection to modify the Duramax exhaust energy to more appropriate levels and to keep the particulate trap clean. Regular filter servicing is required to get rid of built-up ash. Essentially, fuel in the Chevy Duramax is occasionally injected during an exhaust stroke and is ignited within the particulate filter, increasing temperature and oxidizing any particles of soot in the Duramax.

Duramax Truck & Vans Available

Pickups are not the only Duramax Trucks. When equipped with the Duramax engine, both the Savanna and Express vans are max rated for a gross weight of 12,300 lbs and can haul up to 9,600 lbs. The 3.73 axle ratio comes standard with the option to add the RPO G80 limited-slip differential to the Duramax. Duramax equipped Savanna and Express models also come with: Underbody heat shield and remodeled forward floor panel; Option to add a high idle switch to the instrument panel; Diesel engine functionality included in instrument display; 145 Amp standard alternator; and Underhood location for primary battery with a second battery mount on the left frame rail. There is a fuel operated heater available which first in the industry to come factory-installed in any full-size vans. This application rapidly heats the interior of the vehicle during cold weather. The system comes integrated seamlessly into Express chassis of those types of Duramax Truck.
