The R2S turbocharging technology fulfills the requirements of state-of-the-art engine concepts, providing maximum exhaust gas recirculation rates even under full load conditions while significantly reducing emissions. The new high-powered TDCi diesel engine follows the downsizing trend we’ve led with our EcoBoost petrol technology.
Under Sustainable Zoom-Zoom 2030, Mazda aims to reduce corporate average well-to-wheel carbon dioxide emissions to 50% of 2010 levels by 2030, and achieve a 90% reduction by 2050. It intends to achieve this with a policy prioritizing efficiency improvements and measures for cleaneremissions that apply in the real world.
Fuel combustion advances yield less weight, cleaneremissions, and higher reliability. An original Parker concept, the ecology tank is installed below the engine’s combustor and is a reservoir in which unburned fuel accumulates for return to the main fuel tanks following engine shutdown.
More than just the gains in horsepower and torque, the new engine offers improvements in noise, vibration and harshness, along with enhanced fuel economy and cleaneremissions. Standard on all grade levels is the new 2.5-liter liter DOHC inline 4-cylinder direct injection engine, which is rated at 188 horsepower (versus the previous 2.5-liter’s
Additionally, the second compression phase helps to “scavenge” gases [sic] from the first combustion, leading to cleaneremissions and improved thermal efficiency. With power generated every three strokes instead of the traditional four, the engine can deliver more consistent power output.
