EFFECTS OF ENGINE OIL ADDITIVES AND CARBON PARTICLES ON VALVE TRAIN WEAR OF DIESEL ENGINES
This paper deals with the effect of engine oil additives, carbon particles and rocker arm materials on the valve train wear of diesel engines. The tests were performed with an ISUZU 1.8L OHC type diesel engine powered by the motored engine method. The sixteen experimental oil formulations were based on the orthogonal method of experimental design. The results were obtained as follows: (1) It was confirmed there were main effects and interactions between each additive component for the valve train wear with a statistical analysis. (2) The failure phenomena and anti-wear properties of the valve train were affected by the additive components, rocker arm materials and carbon particles. The type of zinc dithiophosphate was a very important factor in the valve train wear.
