The present disclosure describes systems and methods to increase the speed of engine warm up by heating oil with a thermoelectric device and also to generate electricity using the same thermoelectric device, exploiting a temperature gradient between engine oil and exhaust gases. The disclosure describes a vehicle engine, comprising: an engine oil reservoir; an exhaust gas system; and a thermoelectric device having a hot side and a cold side and connected to a battery, wherein, the thermoelectric device is configured such that the hot side is thermally coupled to the exhaust gas system and the cold side is thermally coupled to the engine oil reservoir. A diverter valve and duct are provided in the exhaust gas system to selectively convey exhaust gases to the thermoelectric device located in or adjacent to the engine oil reservoir.
