Simulation and experimental study on motorcycle engine fueled with HHO enriched gasoline
Abstract
Abstract - When adding HHO to gasoline, the combustion efficiency is improved, leading to an increase in maximum pressure and temperature, reducing CO and HC emissions but increasing NOx. When reducing the advance ignition angle, the concentration of CO increases slightly while the concentration of NOx sharply decreases. When adding 10% HHO to gasoline, the optimal advance ignition angle is reduced by 5CA compared to gasoline fueling mode. With the optimal advance ignition angle, when adding 10% HHO to gasoline the indicative engine work cycle increases by 7% and the concentration of NOx increases by 12% compared to gasoline operation. The experimental curves of variation CO, NOx according to engine speed has a lower slope than the corresponding simulation curves. The advance ignition angle of the gasoline-HHO engine can be adjusted to ensure a reasonable increase in power output but does not increase the level of pollutant emissions as compared to gasoline fueling mode.
