  • Patent number: 12129805
    Abstract: A hydrogen concentration calculating process calculates a hydrogen concentration in a specific portion of a target region based on an operating state of an internal combustion engine. The internal combustion engine uses hydrogen as fuel. A downstream passage is a portion of an intake passage of the internal combustion engine that is downstream of a throttle valve. A connecting passage connects a crank chamber of the internal combustion engine to the downstream passage. The target region is a region including the crank chamber and the connecting passage. When a condition is met, in which the hydrogen concentration is greater than or equal to a predetermined determination value, a pressure reduction process causes a pressure in the downstream passage to be lower than that at a point in time when the condition is met.

  • Patent number: 12104862
    Abstract: A heat exchanger includes: a fin group including plate-shaped fins; heat transfer tubes penetrating the plate-shaped fins; and a support plate at an end of the fin group. The heat transfer tubes penetrate the support plate. The heat exchanger is configured to cause a heat medium flowing through the heat transfer tubes to exchange heat with air. End portions of the heat transfer tubes form protrusions protruding from the support plate. The protrusions include: a first protrusion connected to one of the protrusions adjacent to the first protrusion; and a second protrusion connected to a flow path pipe different from one of the protrusions adjacent to the second protrusion. A distance from a tip end of the second protrusion to the support plate is shorter than a distance from a tip end of the first protrusion to the support plate.
