This paper introduces a novel design of an internal combustion engine heat transfer model within a comprehensive simulation environment. The modelling is based on a lumped mass parameters approach. This results in a scalable and modular structure of the model, which in turn permits a flexible design of different engine types. The paper discusses an approach for a heat transfer model, implemented in MATLAB/SIMULINK, the coupling process and the physical interface. The calculation of the combustion process is performed using the 1D engine cycle simulation program BOOST. The 1D cooling simulation program KULI is used to calculate the inner circuits for the water and oil loops. In order to carry out a comprehensive thermal calculation, a coupled simulation with these three different models is performed. With the proposed approach it is possible to simulate the time-dependent warm-up behaviour of the engine and the cooling system.
