Abstract (en)
[origin: WO2012038033A1] The invention relates to a coolant jacket (1) for a liquid-cooled cylinder head for an internal combustion engine having a crankcase, wherein the cylinder head has a gas exchange intake side (ES) having two gas exchange intake valves (2) and a gas exchange exhaust side (AS) having two gas exchange exhaust valves (3), wherein a fuel injection valve (4) is provided on the intake side and an ignition device (5) is provided on the exhaust side between the gas exchange valves (2, 3), wherein the coolant jacket (1) extends as a first partial coolant jacket (6) on the exhaust side, coming from the crankcase, between the gas exchange exhaust valves (3) and then radially outside around the ignition device (5) and the fuel injection valve (4) and further in the direction of the intake side (ES) and the crankcase. The optimal cooling of the ignition device and the fuel injection valve according to the invention enables high specific powers and pressures, which leads to a fuel consumption advantage and a cost advantage.
