Zeppelin Austria tested the impact of New Shell Diesel* on dirty nozzles in a field trial in Austria, in which the nozzles of a chain dredger 323D were taken out, inspected and reinstalled unchanged.
After 177 hours of testing with New Shell Diesel*, the results showed:
- Fuel consumption decreased by 8.8%
- Engine performance improved in all ranges of pressure.
The hydraulic pump test is used by Zeppelin Austria to calculate the engine power in kW by measuring the pump throughput at 3 fixed pressure points with engine rpms fixed at highest level.
To test the effect of New Shell Diesel* on new engines, Zeppelin Austria installed new nozzles into a chain dredger cAt 320D and measure the performance after 257 hours of operation.
To compare the results of New Shell Diesel* and standard diesel, standard diesel was tested with the same test-set up as new Shell Diesel.
After a normal running in period with decreasing fuel consumption – which is usually seen with new nozzles – Zeppelin Austria found that fuel consumption of the CAT 320D test engine stabilised and stayed at the low level with New Shell Diesel*.
In comparison Zeppelin Austria found that with the standard diesel quality the engine performance started to decrease early in the operations.
Zeppelin Austria’s test results showed a difference in performance and fuel consumption of new shell Diesel compared to the standard grade:
- Improved engine performance
- No increase in average fuel consumption
* Refers to Shell Diesel with fuel economy formula. Product name may vary per country. Known as Shell FuelSave Diesel, Shell Diesel Extra, New Shell Diesoline Ultra in other markets.
