[QUOTE="Cowabunga, post: 6725568, member: 718"] I remember the crap synchros in 02, coinciding with Case changing from proper Case to badge engineered New Hollands in that size range. The green engine were not hotter burning though. They were cooler burning with greater heat removed by the cooling system to keep them cooler burning. Lots of people mistake the larger cooling system capacity for the engines running hotter, whereas in fact the opposite is the case. NOx emissions are reduced by cooler combustion. Cooler combustion can be achieved in many ways but EGR, timing and larger cooling systems may be part of the solution, certainly not hotter combustion unless accompanied by SCR aided by diesel exhaust fluid [Adblue]. DEF was never used on the Powerstar engines and not on early NEF engines either. As far as I know the TM series only ever achieved Stage 2 emission compliance, never Stage 3. Didn't the shade of blue change along with the introduction of the yellow flashes? [/QUOTE]
