摘要： In internal combustion engines with direct fuel injection an injector injects fuel into the combustion chamber to form an ignitable fuel/air mixture with separately supplied combustion air, with the mixture to be ignited by a spark plug. The fuel is injected in a cone shape and the electrodes are protected from being wetted with fuel and coking if they are disposed outside the lateral surface of the conical fuel jet generated by the injection nozzle. In order to bring ignitable mixture between the electrodes and to ensure optimal operating behavior of the internal combustion engine by improving the combustion sequence, a combustion chamber configuration is provided such that the conical fuel jet is injected in a free jet which is substantially uninfluenced by the combustion chamber perimeter, and the electrodes of the spark plug project into a fuel vortex extending from the lateral surface during injection.

摘要： In a direct injection internal combustion engine with a combustion chamber which is delimited in each cylinder by a longitudinally movable piston and by the inner wall of a cylinder head, an injector injects fuel into the combustion chamber in order to form an ignitable fuel/air mixture with combustion air that is supplied separately, the mixture being ignited by a spark plug. The fuel is injected in a conical shape and the electrodes are protected from being wetted by fuel and from coking if they are located outside the lateral surface of the cone of fuel produced by the injection nozzle. In order to bring an ignitable mixture between the electrodes and to ensure an optimal operating performance of the internal combustion engine by improving the combustion process, the combustion chamber is configured so that the cone of fuel is injected in a free jet that is substantially unaffected by the perimeter of the combustion chamber, and the electrodes of the spark plug project inside a fuel vortex which emerges from the lateral surface during injection.

摘要： The invention relates to a four-stroke internal combustion engine with compression ignition and internal exhaust gas recirulation by appropriate actuation of inlet and exhaust valves of at least one cylinder/piston unit. The invention provides for at least one inlet valve and at least one exhaust valve of the cylinder/piston unit to be actuable in such a way that the exhaust valve opening takes place before a charge-exchange top dead center position of a piston between an exhaust stroke and an intake stroke, and the exhaust valve closing takes place after this charge-exchange top dead center position at essentially the same time as the inlet valve opens, in order to displace exhaust gas from a combustion space of the cylinder/piston unit through the open exhaust valve into an exhaust duct and subsequently to suck it back from the exhaust duct into the combustion space.

摘要： In a method for operating a spark ignition engine with direct fuel injection, in which the engine is operated either with charge stratification or with a homogeneous charge, the open and/or closed positions of the inlet and exhaust valves are controlled with variable timing depending on the engine operating condition. The timings are determined on the basis of basic timing settings, which are provided in basic timing performance graphs for operation with charge stratification and homogeneous charge operation. The basic timing settings are modified by means of correction values to raise the temperature of the exhaust gas for internal exhaust-gas recirculation and for causing a movement of the charge in the cylinders.
