Additional information

We provide expert advice, often based on simulations performed with bespoke software to engine OEM's, (£4.5M UltraBoost Project – TSB BN008E: scott.bredda@geprecision-engineering.co.uk, dricha69@jaguarlandrover.com). The burning rate models employed in this software were put to a comprehensive test using ported optical engines, LUPOE2, and it was found that flame propagation exhibits three distinct stages: strong flame acceleration followed by more or less constant propagation speed and a decelerating stage near walls. Existing models apply only to the second stage while largest energy release happens within the wall-affected period; for which a simple model for the burning rate has been formulated.
