A side-port exhaust, as is used in the Mazda Renesis, avoids port overlap, one of the causes of this, because the unburned mixture cannot escape.

Excessive pressure in the crankcase can force mist of engine oil into the intake manifold, which can be burned in the same fashion as Diesel fuel, thus causing runaway. One-pedal driving mode and lack of brake application in deceleration and reverse actions. [16]
