And while turbo-lag is acceptable for many, Mazda was determined to minimize its effects. The SkyActiv engine uses a technology they’re calling “Dynamic Pressure Turbo” which uses a 4-3-1 exhaust and a set of valves that change exhaust airflow depending on the RPM. Along with a short exhaust manifold, valves to increase exhaust velocity, and a 4-3-1 exhaust, they aim to minimize turbo-lag while simultaneously maximizing performance and efficiency. The 4-3-1 exhaust is critical for exhaust scavenging, creating the “ejector effect” and helping pull out remaining exhaust gases from the previous firing cylinder.
