The exhaust is, however, relatively low in NOx emissions, as combustion temperatures are lower than in other engines, and also because of some inherent Exhaust Gas Recirculation-EGR-in early engines ; the higher the combustion temperature is, the higher the NOx emissions are ( sir Harry Ricardo proved in the 20's that for every 1 % increase of the proportion of exhaust gas in the admission mix, there's a 45º F reduction in flame temperature ); this allowed Mazda to meet the United States Clean Air Act of 1970 in 1973 with a simple and inexpensive ' thermal reactor ' ( an enlarged open chamber in the exhaust manifold ) by paradoxically enriching the air-fuel ratio to the point where the unburned hydrocarbons ( HC ) in the exhaust would support complete combustion in the thermal reactor ; while piston-engine cars required expensive catalytic converters to deal with both unburned hydrocarbons and NOx emissions.
