A fuel distributor for a fuel injection system for mixture-compressing, spark-ignited internal combustion engines. The fuel distributor rail includes a tubular base body which is processed by forging. At the base body, a first high-pressure output, a second high-pressure output, and a third high-pressure output are provided. The second high-pressure output is situated in an offset manner opposite the first high-pressure output in a first direction along a longitudinal axis of the tubular base body at a predefined distance. The third high-pressure output is situated in an offset manner opposite the second high-pressure output in the first direction along the longitudinal axis at the predefined distance. A first and second holding element, which are used for an at least indirect fastening of the base body, are situated at the tubular base body.

Provided is a two-stroke internal combustion engine, including: a fuel injection valve configured to supply a fuel to a crank chamber; an intake passage configured to allow only air to be sucked thereinto under a negative pressure generated when a piston is actuated; and a scavenging passage that allows communication between the crank chamber and a combustion chamber. The intake passage is branched into a first intake passage and a second intake passage. The first intake passage communicates with the crank chamber. The second intake passage communicates with the scavenging passage. The fuel injection valve is configured to inject the fuel toward at least one of the first intake passage or the crank chamber. Further, air stagnant in the scavenging passage at end of air suction serves as leading air to contribute to scavenging.

An improved injector cup may be used in diesel engines that fits more securely into the engine's cylinder heads to better prevent engine coolant from leaking into the fuel and/or fuel leaking into the coolant. An improved injector cup may be designed to accommodate specific engine types and sizes in order to prevent engine coolant from leaking into the fuel and/or fuel leaking into the coolant.

An axisymmetric injector hold-down load ring includes an annular body and an odd numbered plurality of resilient arms integrally extending from the annular body. Each resilient arm has a curvature concentric with the annular body and extends in a first circumferential direction along an outer periphery of the annular body an equal circumferential distance from a connection with the annular body to a free end. The free end of each resilient arm includes a contact surface facing axially opposite a first surface of the annular body, the contact surface of each resilient arm is axially offset from the first surface of the annular body an equal axial distance. This configuration positions the connections and contact surfaces in radial alignment so that force is transmitted along the resilient arms between the circumferentially spaced connections and contact surfaces when the load ring is in use.

A fuel injector assembly includes a fuel injector defining a longitudinal axis extending between a first axial injector end, and a second axial injector end. The fuel injector further includes, between the first axial injector end and the second axial injector end, a first clamp face and a second clamp face defining a middle plane. The fuel injector assembly further includes a clamp having a forked injector portion forming a slot receiving the fuel injector and in contact with each of the first clamp face and the second clamp face, and a bolting portion having a bolt hole formed therein. The bolt hole defines a bolt hole axis oriented parallel to the longitudinal axis and offset from the middle plane.
