    摘要: An internal combustion engine having an intake manifold, a compressor in fluid communication with the intake manifold, a charge air cooler in fluid communication with and between the compressor and the intake manifold, a throttle controlling fluid communication between the air charge cooler and the intake manifold, and a condensate collection reservoir that collects condensate from the air charge cooler and is in fluid communication with a suction port of a Venturi device in a bypass loop around the throttle. A motive inlet of the Venturi device is in fluid communication upstream of the throttle and a discharge outlet is in fluid communication downstream of the throttle, and under operating conditions that provide an adequate pressure drop across the Venturi device, the suction port draws condensate from the condensate collection reservoir and introduces the condensate into the intake manifold as a mist.
