EFFECTS OF A PRECHAMBER ON NOX FORMATION PROCESS IN THE SL ENGINE

The NOx emission of Toyota lean burn engine is lower than that of a conventional engine due to the presence of a prechamber called a "turbulence generating pot" . The mechanism of this NOx reduction was analyzed experimentally and theoretically. The results showed that large-scale mixing motions of burned gases were caused in the post flame region as a result of the jet flow from the prechamber. It was concluded that the reduction of NOx emission was due to the decrease of temperature gradient and lowered mean temperature of burned gases caused by these motions.
