👉 The HK Fluid, also known as HFC-1234yf, is a high-performance, low-emission aviation fuel designed specifically for use in modern aircraft, particularly those operated by the Hong Kong Airlines. It is a synthetic paraffinic kerosene fuel that offers superior combustion properties, leading to reduced emissions of carbon monoxide, unburned hydrocarbons, and particulate matter compared to conventional jet fuels. This fuel has a higher energy density, which allows for improved fuel efficiency and reduced fuel consumption, making it an environmentally friendly and economically beneficial option for the aviation industry.
