Main Observation

The paper presents the results of thermogravimetric tests of engine oil used in a small turbocharged spark-ignition engine. The main observation from the research was a significant soot contamination of engine oil, that appears even at its low mileage. This indicates that also in the case of port fuel injection spark-ignition engine, high particulate matter emissions may occur. It may therefore turn out that the small city car can be more harmful to the environment than much larger vehicles. A rapid soot contamination of the oil in this engine indicates as well that the oil change interval should be shortened.
