Randomized trial develops a heat rejection prediction method for diesel engines, suggesting improved energy efficiency.

The aim is to create an accurate methodology for predicting heat rejection in diesel engines to enhance energy efficiency.
Developed a one-dimensional thermodynamical model; integrated with a predictive combustion model (DI-Pulse) and a conjugate heat transfer approach.
Conducted a thermal survey in a dynamometer environment for real-world validation.
Verified 1D model accuracy by comparing with test outputs, achieving ±10 kW and ±5 kW precision.
Achieved approximately ±10 kW accuracy for total radiator heat rejection and ±5 kW for cylinder heat rejection.
Significantly reduced reliance on physical testing through optimized cooling elements and combustion parameters.

Epguzel et al. (2026) studied this question.
