    摘要： The invention relates to a cylinder head (1) with liquid-type cooling, having one inlet duct (2), which issues into a combustion chamber, and one outlet duct (3) per cylinder, having a fuel injection device (7) which issues into the combustion chamber and which adjoins the inlet duct (2) and the outlet duct (3), and also having at least one cooling chamber (20) which is arranged in the cylinder head (1), wherein, in a region of the fire deck (9), there is arranged a cooling distribution duct (11) which runs substantially parallel to the fire deck (9) and which is in particular drilled or pre-cast and which issues into an annular chamber (8) surrounding the fuel injection device (7), wherein the annular chamber (8) has at least one substantially radial first cooling bore (13) directed toward a valve web region (14) which is formed between inlet duct (2) and outlet duct (3) and which adjoins the fire deck (9). To improve the cooling of thermally critical regions, there extends laterally from the annular chamber (8) and/or from the cooling distribution duct (11) at least one further cooling bore (15, 16) which is preferably directed substantially tangentially toward the outlet duct (3).

    摘要： The invention relates to a method for starting an internal combustion engine (ICE) operating with combustible gas, with an internal combustion system, especially a large gas engine, according to which burnable gas/air mixture is formed in the admission system (I), especially in a gas mixer (9), upstream from a charger (7), and during the starting phase, compressed air is at least temporarily blown into the cylinder chambers of at least one group (B) of cylinders (1, 4, 5). In order to enable a reliable cold start of the internal combustion engine, the following steps are carried out: the pre-combustion chambers of at least the first group of cylinders are pre-heated to a defined pre-heating temperature; a self-igniting pilot fuel is introduced into the pre-combustion chambers of at least one group (A) of cylinders (2, 3, 6) when a defined rotational speed (n
    1 ) is reached; the gas/air mixture is ignited in the cylinder chambers of said cylinders by means of the self-igniting pilot fuel; and the supply of pressurised air to the respective cylinders is stopped after the ignition of the gas/air mixture blown into the cylinder chambers.

    摘要： The invention relates to a method for starting an internal combustion engine (ICE) operating with combustible gas, with an internal combustion system, especially a large gas engine, wherein a burnable gas/air mixture is formed in the admission system (I), especially in a gas mixer (9), upstream from a charger (7), said engine comprising a first and a second group (A, B) of cylinders (1, 2, 3, 4, 5, 6). During the starting phase, a first group (A) of cylinders (2, 3, 6) is at least temporarily operated by sparking, and compressed air is at least temporarily blown into the cylinder chambers of the second group (B) of cylinders (1, 4, 5). In order to ensure a reliable cold start of the internal combustion engine, the following steps are carried out: the gas/air mixture in the cylinder chambers of the first group (A) of cylinders (2, 3, 6) is ignited by means of at least one starter iginition plug (22) per cylinder; the supply of compressed air to the second group (B) of cylinders (1, 4, 5) is stopped and the gas/air mixture blown into the cylinder chambers of the second group (B) of cylinders (1, 4, 5) is ignited by means of at least one starter ignition plug (22) per cylinder, when the rotational speed of the internal combustion engine exceeds a defined starting rotational speed (n
    2 ); self-igniting pilot fuel is introduced into the cylinder chambers of the first and second groups (A, B) of cylinders (1, 2, 3, 4, 6) when a defined operating temperature is reached in the cylinder chambers of the cylinders (1, 2, 3, 4, 5, 6); and the gas/air mixture is ignited by means of the self-igniting pilot fuel, the starter iginition plugs being deactivated.
