るデイーゼルエンジンの吸気加熱装置。 The intake air heating device is disposed in the middle of an intake passage of a diesel engine to warm intake air flowing through the intake passage, and is composed of a first heat generating member and a second heat generating member. The first heat generating member is equipped with a plurality of plate-shaped heat generating plates made of PTC elements, and the second heat generating member is also equipped with PTC elements.
A plurality of plate-shaped heating plates made of C elements are provided, and the heating plates of the first heating member and the heating plate of the second heating member are arranged in a line across the intake passage. The heating plates of the first heating member and the heating plate of the second heating member are arranged parallel to each other and are arranged parallel to the flow of intake air. The first heat generating plates are arranged opposite to each other with respect to the flow direction of the intake air, and the opposing heat generating plates are arranged extremely close to each other, and the first heat generating plate is disposed in the intake passage. A drive device for displacing the member and the second heat generating member relative to the flow direction is provided,
The diesel engine also includes an intake air amount sensor that detects a physical quantity representative of the intake air amount of the diesel engine and outputs that information, and provides a command to the drive device based on an output signal of the intake air amount sensor. The driving device is characterized by comprising a control device that increases the amount of overlap between the heat generating plate of the first heat generating member and the heat generating plate of the second heat generating member when the amount of intake air increases. A diesel engine intake air heating device.
