Abstract: Magnetic latching valves for a vehicle engine have a housing having a first port and a second port in controlled fluid communication with one another. The housing encloses a linearly translatable armature seated within a solenoid and connected to a primary poppet valve. The armature is movable between an open position and a closed position, respectively, after a pulse of voltage to the solenoid and is in an unpowered state thereafter. A permanent magnet is fixedly seated in a position to magnetically latch the armature in a fully open position. A spring is seated to bias the primary poppet valve closed when the armature is in the closed position. The spring has a spring rate that mechanically relieves pressure by opening the primary poppet valve a distance less than the fully open position when the spring force is exceeded, thereby also allowing flow in the primary flow direction.

The control device includes an electronic control unit executing a temperature raising process of raising the temperature of the post-processing device and a recovery-time process. The temperature raising process includes a stopping process and a rich process. In the stopping process, supply of fuel to several of cylinders is stopped.

In the recovery-time process, the concentration of unburned fuel in exhaust gas discharged to the exhaust passage is made higher than an equivalent concentration, when the temperature raising process is stopped. The equivalent concentration is the concentration of unburned fuel being just enough to react with oxygen in the exhaust gas.
