Abstract
Significant reductions in valve and valve-seat insert wear have been demonstrated with the use of advanced materials for natural gas fueled engines. Total valve and insert wear was reduced by a factor of 10. It was demonstrated that the seat insert wear can be completely eliminated by using ceramic materials. All wear is then limited to the valve seat-face.
The direct benefits to users of natural gas engines with advanced technology valve system materials can include reduced operating costs, greater convenience, and improved availability.
