Patent ID: 10006398

Abstract:
A control system for a multiple fuel internal combustion engine on a vehicle in a fleet of vehicles may include at least one gas analyzer configured to monitor real-time characteristics of gaseous fuel being supplied to the engine, a fleet management data monitoring module, and a cylinder pressure sensor associated with each cylinder of the engine. The control system may further include a data collection module configured to receive real-time fuel characteristics measurements from the gas analyzer, fleet data characteristic of one or more operational parameters, fuel usage, and performance results for vehicles in the fleet, and cylinder pressure measurements from each of the cylinder pressure sensors. An engine electronic control module may calculate one or more actual combustion parameter values from the real-time cylinder pressure measurements, assign weights to fuel characteristics data, cylinder pressure data, and fleet management data, and control at least one of fuel injection and ignition timing based on the weighted data and any difference between calculated actual combustion parameter values for each cylinder and predetermined combustion parameter values.
