An engine heat retention structure 130, and a method of use thereof, are disclosed. The structure comprises a thermal shell 130S arranged to at least partially encapsulate an engine 121 in use, the shell being provided in a spaced apart relationship with the engine to allow circulation of air between the shell and engine. Air is allowed to flow into and out from the structure between the engine and shell via an open skirt portion 130SS. Air is allowed to flow out of the structure via at least one vent flap element 131,133, depending on whether the flap element(s) is/are open or closed. The flap(s) may comprise a pivotable flap portion opened by air flow passing a paddle portion. The flap(s) may be biased with a counterweight arrangement. The structure may be divided into portions via an interior baffle/wall. The engine may be for a motor vehicle.
