A heat exchanger integrated into the transmission oil pan transfers heat from post-catalyst exhaust gases to the transmission oil. Inlet and outlet ducts route exhaust gas between the heat exchanger and an exhaust pipe located downstream of the catalyst. The exhaust pipe accommodates a control valve that diverts exhaust gas flow to the heat exchanger during the warm-up phase, or to the tailpipe during steady state operation. A control function is provided to monitor transmission oil temperature and engine operating conditions and to control actuation of the valve. The main input parameter to the control function is the transmission oil temperature.

Transmission fluid heating using engine exhaust

An apparatus to coat cylinder bores with precise thickness and adhesion having a nozzle for effecting a hollow conical spray pattern of an emulsion about an axis, a highly pressurized supply of emulsion to the nozzle, the emulsion containing solid lubricant in fluid suspension and means for controllably moving the nozzle within the cylinder bore to deposit a coating of the emulsion in the thickness range of 8-13 microns. A method for coating cylinder bores includes preparing the cylinder bore surface to expose fresh metal free of contamination, generating a hollow conical spray consisting of fine mist droplets of a solid lubricant emulsion (the conical spray having an effective base with a diameter greater than the diameter of the cylinder bore), and moving the apex of the conical spray along the axis of the bore at a uniform speed to deposit a coating of the emulsion on the interior of such cylinder bore in a thickness no greater than 20 microns.
