摘要： A method for controlling the speed of an internal combustion engine and a speed control circuit for carrying out the method. For controlling, fuel energy is used as an output variable. The control units are calculated in accordance with a stationary proportion gain which is calculated proportionally to the fuel energy and inversely proportional to the engine speed.

摘要： When switching the fuel to be used for engine operation from gasoline to CNG, in a state where CNG is supplied experimentally to one cylinder serving as a judgment object and gasoline is supplied to other cylinders, whether or not CNG can be supplied to the cylinder serving as a judgment object is judged based on an amount of change ΔPc in fuel pressure inside a CNG delivery pipe (Step S13 to Step S16). When it is judged that a gas fuel can be supplied to all cylinders (Step S19: YES), the fuel to be used for engine operation is switched from the liquid fuel to the gas fuel (Step S20).

摘要： In an engine system of a machine having a multi fuel engine system, the occurrence of transient events such as gear shifts, grade changes and machine speed changes may be anticipated, and a fuel substitution strategy may be adjusted if necessary to optimize performance during the transient events. Transient events at a worksite may be anticipated and mapped by evaluating shift control logic strategies and worksite maps with truck route, speed and topographical information and determining where the fuel substitution strategy cannot meet the power requirements for the transient event. When it is determined that the machine is approaching an anticipated transient event, an appropriate fuel substitution adjustment can be executed to ensure the engine has sufficient power for the transient event.
