Abstract: Provided is a flow control valve which improves a mounting efficiency. An MCV8 includes a housing including a valve-element housing portion, a first communicating aperture which introduces cooling water, which is flown out of a first water channel formed in an engine, to a valve-element housing portion, and a second communicating aperture which discharges the cooling water in the valve-element housing portion to a second water channel formed in the engine; a rotor accommodated in the valve-element housing portion and configured to change a flow rate of the cooling water discharged to the second water channel, according to a rotation angle of the rotor; and a drive mechanism configured to control the rotation angle of the rotor. The first and second communicating apertures open in an engine-side mounting surface of the housing.

Abstract: The exhaust gas recirculation (EGR) system provided herein utilizes a crossover (X) valve that is selectively activated at the direction of the electronic control module (ECM) to mix the high temperature (HT) and low temperature (LT) circuits of the EGR system under certain predetermined operating conditions. Thus, HT circuit fluid (at engine temperatures) is selectively fed into the LT circuit fluid (at ambient temperatures) to heat certain LT circuit components that are normally cooled by the LT circuit before starting the low pressure (LP) EGR in certain cold cycles. When this heating is finished, the X valve is closed to provide normal HT circuit/LT circuit fluid separation. The X valve can be controlled using a rotational actuator or the like. To avoid exposing the LT circuit to the high revolution-per-minute (RPM) operating conditions of the HT circuit, a HT bypass mechanism is provided.

Abstract: An air conditioner for a vehicle including an engine, which serves as a power source and is configured to allow a cooling water to flow therethrough, includes a cooling water circuit, a heater, temperature sensors, and an output controller. The cooling water circuit allows the cooling water to circulate therein in a heating operation. The heater serves as a heat source, other than the engine, configured to heat the cooling water circulating in the cooling water circuit. The temperature sensors are connectable to the cooling water circuit and are configured to detect a temperature of the cooling water. The temperature sensors are positioned upstream and downstream of at least one of the engine and the heater. The output controller is configured to adjust at least an output of the heater based on the temperatures of the cooling water detected by the temperature sensors.
