4.2.11.2

Main fuel oil injection system

The main fuel oil injection system is in use when the engine is operating in diesel mode. When
the engine is operating in gas mode, fuel flows through the main fuel oil injection system at
all times enabling an instant transfer to diesel mode.

The engine internal main fuel oil injection system comprises the following main equipment for
each cylinder:

●

Fuel injection pump

●

High pressure pipe

●

Twin fuel injection valve (for main and pilot injection)

The fuel injection pump design is of the mono-element type designed for injection pressures
up to 150 MPa. The injection pumps have built-in roller tappets, and are also equipped with
pneumatic stop cylinders, which are connected to overspeed protection system.

The high-pressure injection pipe runs between the injection pump and the injection valve. The
pipe is of double wall shielded type and well protected inside the engine hot box.

The twin injection valve is a combined main fuel oil injection and pilot fuel oil injection valve,
which is centrally located in the cylinder head. The main diesel injection part of the valve uses
traditional spring loaded needle design.

The hotbox encloses all main fuel injection equipment and system piping, providing maximum
reliability and safety. The high pressure side of the main injection system is thus completely
separated from the exhaust gas side and the engine lubricating oil spaces. Any leakage in the
hot box is collected to prevent fuel from mixing with lubricating oil. For the same reason the
injection pumps are also completely sealed off from the camshaft compartment.

4.2.11.3

Pilot fuel injection system

The pilot fuel injection system is used to ignite the air-gas mixture in the cylinder when operating
the engine in gas mode. The pilot fuel injection system uses the same external fuel feed system
as the main fuel oil injection system.

The pilot fuel system comprises the following built-on equipment:

●

Pilot fuel oil filter

●

Common rail high pressure pump

●

Common rail piping

●

Twin fuel oil injection valve for each cylinder

The pilot fuel filter is a full flow duplex unit preventing impurities entering the pilot fuel system.
The fineness of the filter is 10 µm.

The high pressure pilot fuel pump is of an engine-driven radial piston type mounted in the free
end of the engine. The delivered fuel pressure is controlled by the engine control system and
is approximately 100 MPa.

Pressurized pilot fuel is delivered from the pump unit into a small diameter common rail pipe.
The common rail pipe delivers pilot fuel to each injection valve and acts as a pressure
accumulator against pressure pulses. The high pressure piping is of double wall shielded type
and well protected inside the hot box. The feed pipes distribute the pilot fuel from the common
rail to the injection valves.

The pilot fuel oil injection valve needle is actuated by a solenoid, which is controlled by the
engine control system. The pilot diesel fuel is admitted through a high pressure connection
screwed in the nozzle holder. When the engine runs in diesel mode the pilot fuel injection is
also in operation to keep the needle clean.
