Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel injection unit suitable for assembly to a cylinder head and for injecting fuel to a cylinder of an internal combustion engine having a common rail fuel system with at least one high pressure fuel pump, the fuel injection unit being connectable to the common rail fuel system, comprising: a first fuel injection valve with a first control valve, a second fuel injection valve with a second control valve, and a single common high pressure fuel accumu…
