Air intake temperature cooling thanks to pressure wave action and adapted air intake geometry

As powertrain electrification gains popularity, gasoline engines must work to keep up with new performance demands and strict emission regulations. As such, a new gasoline engine must be engineered for high performance and high efficiency, as well as for acceptable CO2 levels and the European Union’s Real Driving Emission (RDE). To maintain this tradeoff, for new GTDI engines, lambda 1 upstream of the 3 way catalyst needs to be ensured.
