The Renesis design options two important variations from its predecessors. Initially, the exhaust ports are usually not peripheral but can be found about the side from the housing, which eradicates overlap and lets redesign from the ingestion port location. This produced noticeably extra electric power due to a heightened efficient compression ratio; having said that, Mazda engineers found that when switching the exhaust port on the facet housing, a buildup of carbon in the exhaust port would end the engine from operating.
