Abstract
A powertrain system has an engine, a gaseous fuel tank system having a set of gaseous fuel tanks for storing pressurized gaseous fuel. The gaseous fuel tank system is in fluid communication with the engine. A compressor assembly pressurizes gaseous fuel. In a first powertrain operational mode gaseous fuel is supplied from at least one of the gaseous fuel tanks of the set of gaseous fuel tanks to the engine in a non-operational mode of the compressor assembly. In a second powertrain operational mode gaseous fuel from at least one of the gaseous fuel tanks is pressurized by the compressor assembly in an operational mode of the compressor assembly, and supplied to the engine. A controller predict a first potential change in the engine efficiency; the at least one of the pressure levels, and a needed power output from the engine for operating the compressor assembly, a second potential change in the engine efficiency for the second powertrain operational mode; compare the predicted first potential change with the predicted second potential change to control the compressor assembly.
