| Abstract: | The theoretical foundation of fuel saving in electronically controlled fuel injection (EFI) engine with variable displacement as well as its control circuit and working modes are presented. Taking a home-made car with 4 cylinder engine as object, the fuel consumption and exhaust emission contrast tests at idling and constant speed driving between two working modes(all cylinders working vs. 2 cylinders working)are conducted. The results show that the 2 cylinder working mode can effectively reduce fuel consumption with exhaust emission remaining unchanged. |
