In this work, the mathematical modelling of a internal combustion (IC) engine fed with multiple fuels, and a control scheme for controlling the spark timing of the IC engine are presented. The goal of this work is controlling the IC engine spark timing when it is feed with a hydrogen-enriched E10 blend as fuel, without efficiency and torque losses, at different operating points. The importance of controlling the IC engine spark timing is that the hydrogen and ethanol have a higher combustion velocity than gasoline, so the spark timing is different. The simulation results showed that the influence of ethanol and hydrogen increases thermal and combustion efficiencies of the IC engine by 1.5% and 4.8%, respectively, and that the optimum spark timing is before the top dead centre (BTDC) at 1500 rpm, increasing the torque by 4.42% compared with the use of pure gasoline.

基于人工神经网络的内燃机点火正时建模与控制

在这项工作中，提出了用多种燃料供给的内燃机 (IC) 发动机的数学建模，以及控制 IC 发动机点火正时的控制方案。这项工作的目标是控制 IC 发动机的点火正时，当它以富含氢的 E10 混合物作为燃料时，在不同的工作点没有效率和扭矩损失。控制IC发动机点火正时的重要性在于氢气和乙醇的燃烧速度比汽油高，因此点火正时不同。仿真结果表明，乙醇和氢气的影响使内燃机的热效率和燃烧效率分别提高了 1.5% 和 4.8%，最佳点火正时在 1500 rpm 的上止点（BTDC）之前，提高了内燃机的燃烧效率。扭矩 4。
