McConnell, P J

An exhaust gas liquid heating system is described for a two cylinder internal combustion engine, the system comprising a main heat exchanger spaced from an engine exhaust manifold and connected thereto by a pair of primary exhaust pipes which extend, in use, between exhaust ports of the engine and the main heat exchanger, the main heat exchanger comprising; inner and outer tubes forming a liquid jacket therebetween, inlet means whereby the primary exhaust pipes are respectively connected to communicate with the bore of the inner tube adjacent opposite ends thereof, outlet means whereby a secondary exhaust pipe is connected to communicate with the bore of the inner tube between the ends thereof and at a point substantially mid-way between the inlet means, and end caps forming a fluid seal over the ends of the tubes; and a serial liquid circuit including a holding tank, a pump for pumping liquid from the tank through a series of heat conducting coils wound around the primary and secondary exhaust pipes and in contact therewith, a liquid inlet on the main heat exchanger for providing communication between an end of the coils and the liquid jacket, and a liquid outlet on the man heat exchanger for providing communication between the liquid jacket and a tube extending to the holding tank, the liquid inlet and outlet being spaced apart along a portion of the length of the main heat exchanger being a similar portion over which the inlet and outlet means are spaced whereby exhaust gases passing along the inner tube between the inlet means and outlet means causes heat to be supplied to liquid passing along the liquid jacket between the liquid inlet and liquid outlet.
