Title: Heat exchanger unit
Inventor: FUJIMOTO TORU
IPC: F24F11/76
Filed: 2002-11-01
Abstract: The present invention provides a heat exchanger unit (5) that can appropriately inhibit freezing of a heat exchange element (11), even in cold-climate regions. The heat exchanger unit (5) performs heat exchange and ventilation between an indoor space (SI) and an outdoor space (SO), and is therefore provided with a heat exchange element (11), a supply air passage that is routed via the heat exchange element (11), an exhaust air passage that is routed via the heat exchange element (11), a temperature sensor (51), and a control unit. The temperature sensor (51) detects the outside air temperature. The control unit executes a first freeze inhibit control mode and a second freeze inhibit control mode. The first freeze inhibit control mode inhibits freezing of the heat exchange element (11) if the outside air temperature falls below a first level.  The second freeze inhibit control mode, which inhibits freezing more strongly than the first freeze inhibit control mode, inhibits freezing of the heat exchange element (11) if the outside air temperature falls below a second level (which is lower than the first level).

Title: Plasma coating for cylinder liner and method for applying the same
Inventor: MUCKENHUBER WOLFGANG
IPC: F02F3/12
Filed: 2004-02-09
Abstract: A coating is plasma sprayed onto a cylinder bore and cylinder bead sealing surface of a cylinder block of an internal combustion engine. The coating is harder and/or snore wear resistant than the cylinder block, itself. A cylinder head mounts to the cylinder head sealing surface so that the coating is at least partially disposed between the cylinder block and the cylinder head. The coating therefore protects the cylinder block from exposure to the cavitating pressures that can develop in the combustion chamber of the cylinder. A  depression is formed in the cylinder head sealing surface to account for the thickness of the coating.  A chamfer is formed in the transition between the cylinder bore and the cylinder head sealing surface.
