Abstract
To partially supplant the use of fossil fuels in diesel engines, oxygen-containing fuels, such as biodiesels, are proposed as blending agents in diesel fuel. Engine calibration coefficients to control EGR rate, timings and quantities of fuel injection pulses, turbocharger boost, etc, can be determined to compensate for the lower energy content of such oxygenate blends compared to diesel fuels. According to an embodiment of the disclosure, the fuel quantity of each of multiple injection pulses is increased proportionally to compensate for the impact of oxygenates. An adjustment in the fuel injection quantity is performed in response to a new tank of fuel and the adjustment is applied for that tank of fuel. A fuel compensation factor (FCF) can be determined based on the actual amount of fuel injected compared to the expected amount of diesel fuel at the present operating condition.
