Authors Abstract
Content
A new exhaust gas recirculation (EGR) system has been devised. The system utilises the throttle plate as a secondary controller of EGR flow. Over a series of sudden-deceleration tests, from various engine speeds and loads to idle, the new system showed a complete absence of the misfires which characterised the standard system. Furthermore, EGR flow characteristics differed markedly between the new and standard systems. The new system improved the responsiveness of the EGR system, potentially reducing both HC and NOx emissions. Further advantages of the new system include simplicity and low component cost.
