Abstract The design of a combustion chamber must match the intake air and fuel injection systems to improve the power, specific fuel consumption (SFC) and emissions of diesel engines. Numerical simulations and experimental validations are used to optimize the combustion chamber of an electrically controlled, single-cylinder diesel engine. The power and torque of a single-cylinder diesel engine are predicted using a hybrid Euler-Lagrange method with comparisons to test measurements. A parameterized design is then used to design the combustion chamber. Three key parameters for the re-entrance ratio, depth and inner diameter of the combustion chamber relate to the engine performance (power, torque, SFC and emission). The results show that the hybrid Euler-Lagrange method can be used to design the combustion chamber. The three key parameters strongly affect the engine performance for the given intake air and fuel injection systems.
