The primary objective in addressing Heavy Goods Vehicles (HGVs) is to mitigate fuel consumption and engine temperature inefficiencies that contribute to elevated diesel wastage and higher exhaust emissions. This issue is further compounded by diesel particulate filters (DPFs) frequently blocking, resulting in increased operational costs and necessitating frequent servicing.
Water Fuel Engineering faced the crucial challenge of ensuring the HydroGen electrolyser could generate a substantial volume of oxyhydrogen gas, a critical factor in enhancing the combustion efficiency of HGVs.
In response to this challenge, an enlarged version of the HydroGen unit was developed. By leveraging the catalytic effect, combustion efficiency was improved without increasing the engine temperature. Notably, the innovative approach involved introducing oxyhydrogen directly into the air intake, ensuring a more effective and targeted impact.
A pivotal lesson from this endeavour was the necessity of adapting the size of the HydroGen electrolyser to the specific engine size. This customisation ensures that the device produces the precise amount of oxyhydrogen required. The ability to promote complete combustion of fuel is transformative, enabling the engine to extract more energy per unit of fuel while minimising wasted energy in the form of exhaust emissions. As a result, DPFs are not burdened with capturing as much carbon, presenting a significant advantage in reducing maintenance needs and associated costs.
