I'm doing this from memeory so I might not have all the numbers exactly right. The average gas temperature at the start of the power stroke is probably about ~4000F and diminishes as the power stroke continues to 400oF or there abouts. Windages losses are maybe 10 % of the net power output so the temperature of combustion drives the overall heat input to the engine. The oil pickups heat from just being pumped as well from work being done agaist friction and from h components heated by combustion gases. it's a lot more complicated than this because the overall process is a transient until the engine comes up to stabilized operating temerature. In a diesel it a little diffeerent because it runs with variable fuel to air ratio and hence a variable combustion temperature. An idling diesel take a along time to warm up becayue the temperatures are relatively low due to thelow f/a ratio. It'll warm up faster at part throttle.
