“…Furthermore, these tests are time consuming and expensive; therefore there is the need for an experimental test-rig that can simulate the engine geometrical and operational conditions closely that is efficient and convenient to study deposit formation. Belincanta [12] has studied gasoline deposits using both bench setup and test engine, showing that test setup can be used as an alternative to engine tests. A quick review of the studies on deposit formation shows that most of them are concerned with the effect of fuel and fuel additives [9,10,13,14].…”

The deposition of micron sized lubricant oil droplets similar to oil droplets in blow-by gases of Internal combustion (IC) engines on a hot flat plate was studied using a round impinging jet configuration. Five parameters which simulate the different operational conditions in IC engines were chosen: The impaction nozzle's outlet diameter, additional air flow rate, plate angle, plate temperature, and nozzle to the plate distance. An Experimental test-rig was constructed to acquire deposit weight with different parameter values. To find the conditions of minimum deposition, the deposit's weight was optimized using the Taguchi design of experiment method with respect to the design parameters. Using the experimental data, the predicted optimal value of the deposit weight was confirmed. Analysis of variance showed that plate angle is the most influential factor in deposition of fine oil droplets. Scanning electron microscopy (SEM) was used to investigate the mechanism of deposition.
