A method and system for operating a two-stroke engine includes a fuel system comprising a fuel pressure sensor, fuel temperature sensor and a fuel injector and a controller in communication with the fuel pressure sensor and fuel temperature sensor. The controller controls the fuel injector with a fuel pulsewidth determined by determining a beginning time of a window for measuring fuel pressure, determining an ending time of the window, measuring fuel pressure between the beginning time and the ending time, determining a fuel pulsewidth based on the fuel pressure and fuel temperature and injecting fuel into the two-stroke engine in response to a desired fuel mass.

A method for determining a gas consumption of a gas-powered gas engine or a gas-powered dual-fuel engine. The engine is operated under actual operating conditions, and the actual gas consumption of the engine is acquired under the actual operating conditions. A target gas consumption of the engine to be anticipated under target operating conditions is calculated depending on the actual gas consumption and depending on discrepancies between the actual operating conditions and the target operating conditions.

The invention presented relates to a drive system (100) for providing energy for driving a load. The drive system (100) comprises a compressed gas tank (101) with a pressure sensor (103) and a temperature sensor (105), an energy converter (107) for converting energy from a gas stored in the compressed gas tank (101) into drive energy, a metering system (109) for metering gas from the compressed gas tank (101) into the energy converter (107), and a control device (111) configured to calculate a temperature of gas flowing in the metering system (109) by means of a mathematical model (200) that models an isenthalpic state change of gas flowing into the metering system (109) from the compressed gas tank (101). The control device (111) is furthermore configured to provide measured values that were determined by means of the pressure sensor (103) and/or the temperature sensor (105) as input values to the mathematical model (200). The control device (111) is furthermore configured to provide the calculated temperature of the gas flowing into the metering system (109) to a supplementary system.
