Embodiment Construction
[0032] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.
[0033] Such as Figure 5 As shown, a method for controlling a partitioned and stratified lean-burn engine includes at least the following steps: the first step is to divide the cylinder into at least two combustion zones, and the size of each combustion zone is different, so that the engine can realize zoned combustion ;
[0034] In the second step, a spark plug, an exhaust pipe and an intake pipe are connected on the cylinder head corresponding to the cylinder of each combustion chamber, and a cylinder pipe divider plate is arranged in each intake pipe, and the intake pipe, especially A section of the intake pipe close to the cylinder is divided into two large and small inta...
