Though not the first electrically controlled diesel in the light-duty market (the Ford 7.3L Power Stroke was), the General Motors 6.6L Duramax is recognized as one of the most sophisticated. It boasts four-valve aluminum cylinder heads, excellent component packaging, and a reputation for durability, power, fuel economy, low combustion noise, and very little vibration. Ironically, this high-tech engine exists due to the government-mandated emissions standards that required a 90-percent reduction in tailpipe discharge from previous mechanically fueled designs. Thus, gasoline-style engine management was required to tame and improve upon the diesel engine.
High-Tech Duramax Solution To achieve the desired emissions, noise, and vibration goals, the uncontrolled combustion stage needed to be minimized or eliminated. This could only be done through electronic control of the injector and an extremely high-pressure fuel source.
In the case of the Duramax, GM uses a Bosch common-rail fuel system. The intent was to eliminate or at least minimize the central core of a mechanical injector spray pattern that would evoke the uncontrolled combustion event until a reaction zone (where the heat from the burned fuel travels into the unburned fuel) could be established. Though there were evolutionary changes over the years to the engine and controls, most basic component functions stayed the same.
The notable updates came when GM switched to the LLY engine in 2004 1/2 and added a variable geometry turbocharger, EGR, and altered the cylinder head and injector design. Then came the LBZ in 2006 and it featured a lower compression ratio, higher injection pressure, and an improved engine block design. The LMM version that arrived in 20071/2 added an electrically controlled throttle body that works in conjunction with the EGR and diesel particulate filter (DPF) to evoke the regeneration/cleaning process.
The later LLY, as well as newer versions of the Duramax, used a new injector identified as an IQA, or injector quantity adjustment. It is also referred to as injector flow rate programming (IFRP), and involves values assigned to each injector after flow testing at the production plant. During the manufacturing process, each injector is tested and its flow rate is measured at several duty cycles. These measurements are recorded as the injector flow rate value. This data is then recorded on the bar code label. It is laser etched as a hex number on the body of the injector before it is shipped to the Duramax engine plant in Moraine, Ohio.
