Gas admission valve
ACTUATION FORCE
All valve actuation forces are generated magnetically through an E-core solenoid device. Magnetic flux generated in the E-core solenoid assembly attracts a low carbon steel plate (the armature) that is attached to the valve mechanism. The E-core produces very high forces over short travels. The valve mechanism travels 0.50 mm from full closed to full open. The short travel along with the high forces result in fast and consistent opening and closing response.

VALVE
The valve is similar to an air (or gas) compressor valve. It is a face type poppet with multiple concentric grooves. The moving metering plate is spring loaded (and pressure loaded) against the lower stop & metering plate and is pulled off the lower stop & metering plate by the E-core solenoid assembly. When the plates are separated, gas flows from the grooves in the moving metering plate to the grooves in the lower stop & metering plate (View valve closed). When the moving metering plate and the lower stop & metering plate are in contact, gas cannot pass from the grooves in the moving metering plate to the grooves in the lower stop & metering plate (View valve open).

Fuel system on engine
The arrangement on the engine consist of covering system, low pressure system, main injection and pilot injection systems with control devices and fuel condition monitoring systems.
System components
- 01 Covering system
- 02 Low pressure system
- 03 Main injection system
- 04 Pilot injection system
Covering system
A-BANK
The hot-box covering system can be divided into four categories, cover for fuel piping, end covers, side covers and covers between the cylinder heads.
System components
- 01 Covers for fuel piping
- 02 Side covers, upper part
- 03 Side covers, lower part
- 04 End cover FE, lower part
- 05 End cover FE, upper part
- 06 End cover DE, lower part
- 07 End cover DE, upper part
- 08 Covers for fuel piping from
A-bank to B-bank
B-BANK
The hot-box covering system can be divided into four categories, cover for fuel piping, end covers, side covers and covers between the cylinder heads.
System components
- 02 Side covers, upper part
- 03 Side covers, lower part
- 04 End cover FE, lower part
- 05 End cover FE, upper part
- 06 End cover DE, lower part
- 07 End cover DE, upper part
COVERS FROM A-BANK TO B-BANK
The Hot-box covers are designed to form an isolated area. The splash covers are giving even higher protection for the same area by preventing direct pressurized fuel injection to hot surfaces.
System components
- 01 Covers for fuel piping from
A-bank to B-bank
Hot-box side covers, upper part
Basically the Hot-box side covers are built on the frame, which at the lower end are retained by means of screws onto the lower side cover profile. The lower side cower in turn is attached onto the side surface of the engine block. At the upper end, the system is attached to the cylinder head. Side cover consist of three covers as lower cover, middle cover and upper cover.
Every side cover is secured to the frame with latch mechanism.
