VW suggests engine downsizing is done; emissions rules are the reason

Green Car Reports

When it comes to improving fuel efficiency, simply making an engine smaller is a fairly direct way to get results. They have downsized engines across model lines, usually adding turbochargers at the same time to match the power output of the larger-displacement engines that they. emissions VW downsizing Fuel Economy TurbochargingIt's the approach that many automakers have taken in recent years.

Split injection Miller cycle with boost decreases knock tendency and increases torque in downsized engine

Green Car Congress

Researchers at Tianjin University in China report that combing split injection to the Miller cycle with boost pressure can effectively decrease the knock tendency and increase the engine torque in a downsized spark-ignition engine. The current development of downsized spark ignition (SI) engines with boost pressure is a proven way of increasing the thermal efficiency and reducing CO 2 emissions. Engines Fuel Efficiency

New Efficient Supercharger with Variable Drive for Downsized Gasoline Engines

Green Car Congress

Turbo lag can become increasingly intrusive as engines get smaller. Superchargers are mechanically geared to enhance performance at either low or high engine speeds. The Rotrak solution overcomes this constraint by connecting the supercharger to the engine by a compact variable drive, allowing efficient operation across the whole engine speed range. The need to reduce CO 2 emissions is leading to downsized engines, heavily boosted by turbo- or supercharging.
