An engine including a main fuel injection valve, a pilot fuel injection valve, a liquid fuel supply rail pipe, and a pilot fuel supply rail pipe. The main fuel injection valve supplies liquid fuel from the liquid fuel supply rail pipe to a combustion chamber during combustion in a diffusion combustion system. The pilot fuel injection valve supplies pilot fuel from the pilot fuel supply rail pipe to the combustion chamber in order to ignite gaseous fuel during combustion in a premixed combustion system. The liquid fuel supply rail pipe is disposed at one side of an imaginary vertical plane (P1) including an axis of a crank shaft. The pilot fuel supply rail pipe is disposed at the side of the imaginary vertical plane at which the liquid fuel supply rail pipe is disposed.

A method for controlling a high-pressure pump for the injection of fuel into a combustion engine, the high-pressure pump being connected to a camshaft of the combustion engine, wherein the high-pressure pump is controlled in a camshaft-synchronous manner by ascertaining an angular offset between the flank positions of a camshaft pulse-generating wheel and a predefinable point above the bottom dead center of a cam of the high-pressure pump on the camshaft.

A force transfer arrangement for transferring a force from a rotating camshaft to an output device, that is able to reduce the transversal force on the camshaft. The proposed connection device force transfer arrangement is configured to cause forces to act on the camshaft from substantially opposite directions which effectively produces a resultant force on the camshaft to be close to zero, or at least be reduced compared to prior art force transfer solutions. Thus, the transverse forces on the camshaft and therefore on e.g. bearings supporting the camshaft are reduced thereby the lifetime of the bearings is prolonged.
