Dual-fuel and spark ignited gas internal combustion engine excess air control system and method

摘要: An excess air control system and method (10) for a dual-fuel or spark ignition gas internal combustion engine (12) is provided. The controller (18) senses the exhaust temperature, manifold pressure, measures power output of (12). Based on these measurements characterization data, target pressure computed. compared with sensed an blowoff valve coupled to bypass line linking intake turbocharger (36) (40) either opened closed achieve pressure.
