Scania factory we wereshown aprototypeengine based on Scania's vaunted Homogenous Charge-Compression Ignition (HCCI) concept that uses the leanest possible air/fuel mixture to keep emissions down. The example seen by CM also featured hydraulically operated variable valve timing: withthe right fuel the HCCI engine is said to produce zero NOx and zero particulates. Scania is keen to develop HCCI as its platform for Euro-6 and beyond.
