Abstract
A novel fuel injection unit for a large internal combustion engine includes a common rail fuel system. The fuel injection unit of the invention is constructed of at least a high pressure fuel accumulator specific for the fuel injection unit, a flow fuse, a first fuel injection valve with a control valve, and a second fuel injection valve with a control valve. The first fuel injection valve is a smaller one used for injecting at most 30% of the fuel required in full load operation of a diesel mode.
