  "textContent": "An engine fueled with a gaseous fuel includes a storage vessel storing the gaseous fuel in the gas state. For an engine speed and engine load, a storage-pressure brake thermal efficiency (where an injection pressure equals the storage pressure) is compared to a second-pressure brake thermal efficiency (where the injection pressure is equal to the second pressure and based on a parasitic energy cost of pressurizing the gaseous fuel from the storage pressure to the second pressure). The gaseous fuel is pressurized from the storage pressure to the second pressure when the second-pressure brake thermal efficiency is greater than the storage-pressure brake thermal efficiency.",
