Abstract: A fuel-injection system for internal combustion engines has at least one fuel injector injecting fuel into a combustion chamber, which is delimited by a cylinder wall in which a piston is guided. A spark plug projects into the combustion chamber, and the fuel injector is located in the combustion chamber in the region of a gas-intake valve toward the cylinder wall. The fuel injector produces a plurality of fuel jets at least one of these fuel jets being tangentially oriented to the region of the spark plug.

Abstract: A fuel injection system for internal combustion engines having a fuel injector that injects fuel into a combustion chamber, which is delimited by a cylinder wall in which a piston is guided, and having a spark plug that projects into the combustion chamber, the fuel injector injecting a plurality of injection jets into the combustion chamber. The injection jets generate a cone-shaped mixture cloud having an elliptical cross-section in the combustion chamber.

Abstract: A fuel injection system (1) for internal combustion engines (1) having a fuel injector (5) that injects fuel into a combustion chamber (7), which is delimited by a cylinder wall (13) in which a piston (6) is guided, and having a spark plug (4) that projects into the combustion chamber (7), the fuel injector (5) injecting a plurality of injection jets (10) into the combustion chamber (7). The injection jets (10) generate a cone-shaped mixture cloud (9) having an elliptical cross-section in the combustion chamber (7).

Abstract: A spark-plug assembly comprises a fitting mounted on the piston cylinder of an internal-combustion engine and formed with a generally closed firing chamber, at least one firing port extending between the firing chamber and the piston cylinder for fluid communication therebetween, and a storage compartment opening only into the firing chamber. The fitting being provided with a flame-blocking element or formation preventing the entrance of a flame front from the firing chamber into the storage compartment. This firing chamber is open substantially only to the storage compartment and to the piston cylinder. A spark plug has electrodes in the firing chamber. The electrodes form a spark gap lying in the firing chamber between the storage compartment and the port and the storage compartment opens only into the firing chamber.
