Hi-Tech Products

Prometheus prechamber technologies use patented flow dynamics to prevent misfire and preignition, increase engine efficiency and decrease greenhouse gas emissions. This is accomplished by enhancing the flame propagation of ultra-lean and highly diluted mixtures of fossil fuels such as natural gas and gasoline, in addition to zero-carbon fuels such as hydrogen, ammonia, and carbon-neutral fuels such as methane and methanol.
