As to chemical reaction as compared with gasoline, the charactristics of hydrogen is higher combustion velocity and lower energy needed for ignition. The gasoline engine indicated thermal efficiency can be increa- sed when the engine fueled by hydrogen-gasoline combined fuel. The re- sults show that the engine optimum ignition angle is decreased with the increase of the supplying hydogen quantity; the maximum excessive air coefficient can be added wit which the engine speed fluctuation is not evidently in existence during the engine operation; the indicated specific fuel consumption is evidently decreased with a rise in supplying hydrogen quantity; after the containing hydrogen ratio is larger than 5%, the in- crease extent of the indicated specific fuel consumption is smaller; CO and HC concentration in exhaust is notably decreased because of delivering a small quantity hydrogen.

氢气在燃烧化学反应方面和汽油相比,只有燃烧速度快,着火界限宽、最低点火能量小等特点。在汽油机的燃料中加入少量氢气后,可以降低发动机的指示比油耗,减小排气中CO和HC的浓度。本文主要论述加氢比例X_H对发动机性能的影响规律。(X_H=G_H/(G_H+Gg);GH—氢气消耗量kg/h; G_g/——汽油耗量kg/h)试验表明;随着X_H的增大,发动机的最佳点火提前角应向减小的方向改变。随着X_H的增大,使发动机稳定运转的最大过量空气系数α_(∑max)可以向增大的方向调整。随着X_H的增大,发动机的指示比油耗明显降低。当X_H超过5%之后,其比油耗的减小幅度逐渐变小。加氢对汽油机排气中的CO和HC的浓度的控制更为有效。
