Abstract

The effects of different lubricating oils on exhaust hydrocarbon emissions from a gasoline-fuelled engine have been studied. Unburned hydrocarbon formation due to fuel absorption/desorption in the cylinder liner lubricating oil film has been reviewed to support the investigation. Six lubricant types have been tested: two synthetic oils (SAE 5W30 and SAE 5W40), two semi-synthetic oils (SAE 15W40 and SAE 20W50), and two mineral oils (SAE 15W40 and SAE 20W50). Experiments were performed in a production engine mounted in a bench test dynamometer, varying engine speed through the load applied in the dynamometer in the range from 1500 to 6000 rev/min. A strong correlation between hydrocarbon emissions and lubricant viscosity has been found. Synthetic oils showed the lowest hydrocarbon emission levels, especially at low engine speed operation.
