摘要

A method for adjusting a fuel control system of an engine capable of operating in both a first mode during which only a first fuel is delivered to the engine and a second mode during which both the first fuel and a second fuel are delivered to the engine includes operating the engine in the first mode during which a governor output value (XM1) is established and stored in memory. The engine is then operated in the second mode during which a governor output value (XM2) is established. The governor output value (XM2) is compared with the stored governor output value (XM1) and a stored second fuel energy content value is adjusted based upon the comparison. The actual energy content of the second fuel can also be directly calculated.
