Abstract: An internal combustion engine is provided including an engine block defining a plurality of cylinders. A cylinder head is attached to the engine block and includes a plurality of intake ports and a plurality of exhaust ports in communication with the plurality of cylinders. An intake manifold is in communication with the plurality of intake ports and an exhaust passages connect to the plurality of exhaust ports. A turbocharger is in communication with the exhaust passage and has an impeller driven by exhaust gasses from the exhaust passage. The turbocharger includes a compressor for supplying compressed air to the throttle body. A water-to-air pre-charge air cooler is disposed in a flow passage between an outlet of the compressor and the throttle body.

Abstract: A burner type catalytic converter heater composed of an air intake housing having a peripheral mounting flange for universal mounting to an exhaust system upstream of the catalytic converter. A nozzle body is provided having a central portion whereat an orifice delivers atomized fuel and an annular flange portion which interfaces with the air intake housing to define an air intake chamber on an upstream side thereof. A cylindrical combustion chamber housing is provided and a single-stage vortex body is connected to one end of the combustion chamber housing, wherein vanes of the vortex body adjoin a downstream side of the annular flange portion.
