ECU dynamically adjust fuel volume (controlling injector opening duration) by monitoring the air/fuel ratio at exhaust (O2 sensor).
Modern cars are equipped with knock sensor, mixing fuel shouldnt be a big problem, stock ECUs have lot of safety features. Every manufacturers implement knock retard differently.
GULL 98 is fine. There used to be a regulation that by 201x every brand has to include at least 10% renewable fuel (bio ethanol etc), but no one seems to enforce that anymore...作者: tomy1234 时间: 2013-1-21 10:23:24
