Abstract
The spark plug for the rotary engine is subject to the higher
thermal load environment because of its structure compared to the
ordinary reciprocating engine's plug. Effort has been made to
develop the rotary engine's spark plug under such condition as
a key technology to secure its high heat resistance and to improve
the ignitability at the same time. The need to take actions toward
environmental pollutants is required recently, such as improving
fuel consumption and reducing exhaust emissions. And the demand for
sophisticated product has been increased. A spark plug was newly
developed for the side exhaust port rotary engine to realize the
low fuel consumption and high power and introduced to the
market.
The newly developed spark plug modified the center electrode,
the ground electrode, and insulator to realize both drastically
improvement of the ignitability and high heat resistance.
This paper describes overview of the development of the new
spark plug.
