An engine heat retention structure 130 which comprises a thermal shell 130S which at least partially encapsulates an engine 121. The shell is spaces away from the engine to allow air to circulate between them. The shell comprises a skirt portion 130SS downwardly directed. Air flow is prevented out of the structure the top of the structure and the skirt portion allows air to flow upwardly or downwardly. A deflector 147or fan 143 for directing air into the structure may be provided. The structure prevents heat loss from the engine, for example when parked. The efficiency of the engine is improved as it is dependent on the viscosity of oil (thus temperature). By maintaining heat normal operating temperature is reached quickly following cold starts. An engine with such a heat retainer, vehicle using such an engine and method of retaining heat are also disclosed.
