“…1, the HHO generator consists of components: battery, signal generator module (SGM), electrolyser, water storage and bubbler. The power provided by battery is converted to pulsed power via SGM (18). There are different techniques recommended in literature to diminish bubbles layer on the electrodes active surfaces such as "Ultrasonic waves", "Magnetic field" and "pulsed power" (44)(45)(46).…”

“…In this research, the pulsed power is chosen for electrolyser to produce HHO gas from water. The detailed analysis of HHO cell was presented in our previous paper (18). The efficiency of a flat plate HHO cell was evaluated by differing different parameters such as electrodes distance, DC power, pulsed power, ultrasonic waves and magnetic field.…”

“…CO is produced by internal combustion engines as the result of incomplete combustion of fossil fuels in combustion chamber. To use hydrogen for CO reduction, water should go through an electrochemical process to produce hydroxyl (HHO) or Brown's gas which is a mixture of oxygen and hydrogen (17)(18)(19). The convectional water electrolysers produce pure hydrogen in a way that a separator membrane is used to separate hydrogen and oxygen (20,21).…”

Environmental crisis requires using cleaner energy sources for different sectors including the transportation. Hydrogen can support the transition of the automotive industry from petrol and diesel into a sustainable fuel. It could be the main source of energy or the auxiliary fuel in vehicles. As an auxiliary fuel, it has recently been considered in hydroxyl (HHO) form for reducing the emissions from transportation fleet. In this study, an HHO generator with the optimum power consumption was utilised for HHO injection into the intake manifold of a petrol engine as the case study. High concentration of CO is expected to be produced during idling, so the experiments were designed to inject ultra-low HHO for reducing CO emissions. The results were very promising, and it was shown that the CO emission could be reduced by about 98%. Furthermore, a novel design was developed based on the concept of waste heat recovery (WHR) for powering the HHO unit. Engine was simulated in AVL software to design a thermoelectric generators (TEG) for running the HHO unit. Based on the results, TEG can provide the energy required for HHO unit as the energy output of the TEG was between 91 kJ to 169 kJ for the case study while the energy consumption of the proposed HHO generator was just about a Vibe parameter ∝ SubscriptsCrank shaft angle (degree)

“…The increasing rates of greenhouse gases and other emissions from different sectors, including transportation, are believed to be having a significant negative impact on our environment [1,2]. The surplus level of greenhouse gases, such as carbon dioxide, has resulted in an increase in atmospheric temperature and a shortage of freshwater [3].…”

This study aims to investigate the effect of the port injection of ammonia on performance, knock and NOx emission across a range of engine speeds in a gasoline/ethanol dual-fuel engine. An experimentally validated numerical model of a naturally aspirated spark-ignition (SI) engine was developed in AVL BOOST for the purpose of this investigation. The vibe two zone combustion model, which is widely used for the mathematical modeling of spark-ignition engines is employed for the numerical analysis of the combustion process. A significant reduction of ~50% in NOx emissions was observed across the engine speed range. However, the port injection of ammonia imposed some negative impacts on engine equivalent BSFC, CO and HC emissions, increasing these parameters by 3%, 30% and 21%, respectively, at the 10% ammonia injection ratio. Additionally, the minimum octane number of primary fuel required to prevent knock was reduced by up to 3.6% by adding ammonia between 5 and 10%. All in all, the injection of ammonia inside a bio-fueled engine could make it robust and produce less NOx, while having some undesirable effects on BSFC, CO and HC emissions.
