ABSTRACT:
The present invention has a structure of a lean-burn combustion engine 25 for burning a fuel by increasing the proportion of air to the fuel, a swirl control valve 8 for regulating a swirl intensity of combustion air inside an intake port in a lean-burn operation range of the lean-burn combustion engine 25, an accelerator pedal 1 for setting an acceleration request of a driver, and mechanical connection for mechanically connecting the accelerator pedal 1 to the swirl control valve 8, having a mechanism capable of setting the swirl control valve opening so that a lean limit can be expanded. Also, the invention has a structure of an intake system including the swirl control valve for regulating a swirl intensity of combustion air inside an intake port and a a driving mechanism for the valve can be produced easily and at a low cost, and a lean limit can be expanded.
