Fuel injection for a four-stroke IC motor gives a simultaneous delivery of a low octane and a high octane fuel for optimum combustion under fuel injection control

摘要

For the operation of a four-stroke internal combustion motor, the fuel is a simultaneous feed of a secondary low octane fuel (3) and a main high octane fuel (4). The fuel injection system is controlled (5,6) to give an injection duration time and injected fuel vol. for the optimum combustion for the motor operation and the characteristics of the two fuels.
