Exhaust gas recirculation for emissions control
Patent
·
OSTI ID:7144172
Exhaust gas from an internal combustion piston engine is recirculated through a rich mixture auxiliary intake passage leading to an auxiliary combustion chamber. A valve controls the relative proportions of exhaust gas and air supplied to the auxiliary intake passage, and the valve is controlled by means responsive to suction pressure downstream from the auxiliary throttle valve, and is also responsive to movement of that throttle valve.
