Systems and methods of operating an engine with a varying fuel composition. In one example, a split injection is performed during engine cranking with at least some fuel injected in the intake stroke and some fuel injected in the compression stroke. Further, a split ratio of the injection is adjusted based on the alcohol content of the injected fuel.

The present invention involves the field of evaporator technology. Specifically, a composite methanol evapator, including the box, the inner wall of the box is set with a filter, a two -layer evaporation mechanism is set up above the filter.Uniformly distributed, the inner wall of the box is set with multiple groups of round tubes, and the two ends of the multiple groups of round tubes are fixed with the sides of the inner wall of the box. There are multiple sets of atomized nozzles below the round tube.The end wall of the input liquid is connected to the inner wall of the round tube. The left side of the round tube runs through the inner wall of the box and extends to the outer fixing connection of the T -shaped tube.Users can use the liquid pump to spray liquid methanol through the atomized noble spray head on the evaporation mechanism. The motor will drive the evaporation mechanism to rotate the temperature in the process of using the use process, so as to avoid the spray of liquid methanol in the evaporation mechanism.Temperature cannot recover in time and reduce the evaporation efficiency of methanol.
