When considering rotary engines, the Wankel engine often comes to mind due to its high power-to-weight ratio, though it suffers from drawbacks in fuel economy, emissions, and durability. In contrast, ...

The rotary's reliability problem was mostly an owner problem. Here's the disciplined playbook that keeps FC 13Bs alive.
