CA 50 - 50% burn (crank angle) from a 'rate of heat release vs crank angle' curve for a given engine
https://www.researchgate.net/post/How_can_I_calculate_50_burn_crank_angle_from_a_rate_of_heat_release_vs_crank_angle_curve_for_a_given_engine
CA 50 - 50% burn (crank angle) is ideally located at 8-12 aTDC in order to obtain high brake thermal efficiency.
