A cooling system for an automotive propulsion system is provided. The cooling system includes a housing defining a housing inlet and a housing outlet. An exhaust pipe may be configured to be fluidly connected to an automotive engine, the exhaust pipe and defining a passageway for exhausting exhaust gases originating with the automotive engine. The housing outlet is connected in fluid communication with the passageway of the exhaust pipe, which may be through a cooling conduit. The exhaust pipe is configured to suck air from the housing outlet into the exhaust pipe to define a cooling air flow path from the housing inlet to the passageway of the exhaust pipe. In one variation, the outlet of the cooling conduit has an open end placed in a slipstream of the vehicle rather than in the exhaust pipe.

Cooling by suction of air

A fuel tank assembly is fillable by a fuel pump. The fuel pump is configured such that the existence of a predetermined condition causes the pump to stop delivering fuel. The fuel tank assembly includes a tank defining a chamber, a fill tube, and a fuel pump shut-off system. The fill tube defines an opening configured to receive a nozzle of the pump, and a passageway that provides fluid communication between the opening and the chamber to transfer liquid fuel from the nozzle to the chamber. The fuel pump shut-off system is configured to selectively generate the predetermined condition, and is configured such that whether the predetermined condition exists depends on the total volume of liquid fuel in the chamber and the chemical composition of the liquid fuel in the chamber.
