The best fuel mode that can be used is “Semi-Sequential” injection
where half of the fuel pulse if fed to the cylinder on the correct cycle of the stroke (i.e. Just before or during
the intake stroke) and half the fuel is injected at the wrong half of the cycle (i.e. During the compression
stroke). Semi-sequential injection has the advantage that at least half of the fuel is injected on the correct
part of the cycle leading to better atomisation than with multipoint. In addition, the fuel is always injected in
the same positions for every cylinder, thus leading to smoother, more even running of the engine.
