Abstract: The invention relates to a device and a method for ascertaining an injection time and/or an amount of a liquefied gas fuel—such as liquefied petroleum gas (LPG), natural gas (CNG), liquefied natural gas (LNG), biogas or hydrogen (H2)—to be delivered to a cylinder of an engine (19) in order to operate the engine (19) in a bivalent or trivalent fuel operating mode, said device being designed in such a way that the ascertained injection time of the liquefied gas fuel is dependent on an ascertained calorific power or an ascertained gas mixture characteristic. A gas mixture analysis module (7) is used for optimizing combustion. A gas start mechanism allows a vehicle to be started on gas power even at low temperatures.

Abstract: A fitting for a liquid gas bottle with a gas consumer connection piece, with a gas inlet opening on the underside, with a gas conducting connection between the gas inlet opening and the gas consumer connection piece, with a rotary handle, which can be turned into an open position and into a closed position, wherein in the open position gas can flow from the gas inlet opening to the gas consumer connection piece and in the closed position no gas can flow from the gas inlet opening to the gas consumer connection piece, with a closable opening on the upper side of the fitting, with a gas conducting connection which connects the closable opening on the upper side with an opening at the underside in such a way that refilling a connected gas bottle with gas through the underside and through the closable opening is possible, characterized in that the edge of the closable opening is part of the rotary handle.
