THE EFFECTS OF RUNNING A 2.5L PERKINS DIRECT INJECTED ENGINE ON ALKALI REFINED RAPE- SEED OIL FOR 1000 HOURS

During duty cycles requiring high engine output and normal, but elevated, engine temperatures, alkali refined rape- seed oil provided satisfactory performance in a Perkins D3 152 direct injected compression ignition engine. Greater carbon deposits were found to form in both the inlet and exhaust valve ports, valve stems and exhaust manifold but as these were of a soft nature had no adverse effect on engine wear or performance during 500 hours of normal farm work. When used as a "second" tractor for light duty cycles with low engine output and normal but lower engine temperatures considerable carbon deposits were found to form. These deposits were sufficient to reduce the top piston ring end gaps and cause the breakage of two piston rings. Rotary injector pump seizure was found to occur where inadequate clearance for the heavier viscosity oil existed. One design of rotor provided satisfactory service over 1000 hours and appeared to be receiving adequate lubrication. The engine lubricating oil became high in both acidity and viscosity after 50 engine recorded hours and at the end of 100 hours was considered unsuitable for further use. From the results obtained with the Leyland Tractor during three years and 1000 hours of both hot and cold running the 100 per cent use of alkali refined rape- seed oil could not be recommended. The paper is No. 83017. (Author/TRRL)
