Modernization of fuel equipment is directed on increasing the injection pressure, providing qualitative spraying and complete burning of the fuel.

As results of high-pressure fuel pumps sealing follows these benefits/effects:

1. Decreasing temperature of exhaust gases with 20-50 degrees centigrade.
2. Increasing engine rotation speed till nominal.
3. Decreasing the minimal stable rotational frequency of the main engines.
This will in significant degree improve engine’s maneuvering characteristic.

4. Reducing fuel consumption up to 10 per cent.*
5. Reducing quantity of harmful emissions to the atmosphere.
6. Total absence of vibration that is most important for Gas Carriers.
7. The exception of fires in under-piston spaces and its consequences.
8. Gas-turbo-heater and waste heat boilers do not become clogged with scale and do not subject to fires.
9. Cessation of exhaust valves' burning through.
10. Decreasing wear of engine’s parts (cylinder-and-piston unit).
11. Suction valves of EDS design do not subject to failure unlike to standard ones (“MC” type main engines).
12. When it is necessary to transmit engine to the light sorts of fuel, as for example Panama Canal Regulation demands, engines with EDS suction valves could be easy started. To do the same is problematically on engine with standard suction valves, especially on “MC” series main engines.
13. It is possible to repair suction valves of EDS design by mechanics on board.

* The size of reducing fuel consumption is not constant for all vessels. But based on increasing the injection pressure and other indirect parameters, it can be up to 10
per cent.
