Abstract
Particles smaller than 50 nanometers emitted from an internal combustion engine, and serving as nuclei for forming PM (particulate matter), are removed to decrease the number of PM particles that are emitted to atmosphere. High efficiency filters are provided in passages that feed fluids into the combustion chamber, e.g., intake air, fuel and engine oil, in order to remove particles smaller than 50 nanometers serving as nuclei for forming PM.
