The change in internal energy is equal to the sum of the work done on the engine and the heat transferred to the cooling system.
E = work done on the engine + heat transferred to cooling system
E = 637 Joules + 2331 Joules
E = 2968 Joules
Therefore, the change in internal energy of the engine is 2968 Joules.
