    摘要: There is provided a method for starting a spark ignition engine having multiple cylinders. The method may comprise supplying air and fuel for restart into a first cylinder before said engine completely stops, and igniting the mixture of said air and said fuel in said first cylinder in response to an engine restart request, wherein said first cylinder is on an expansion stroke when said engine stops. The method may also include, after said piston in said first cylinder starts moving, injecting fuel into a second cylinder that is on a compression stroke when said engine stops, on a compression stroke where a piston of said second cylinder is moving in a direction opposite to an operative direction of said piston in said first cylinder.
