Calsion methanol engines utilize M100 methanol as a clean energy source. Featuring a high compression ratio, high-energy ignition, and a high-turnover combustion chamber design, along with advanced technologies such as intake turbocharging with intercooling and multi-point fuel injection, these engines achieve higher combustion efficiency and greater power output. This engine delivers superior fuel economy and exceptional cost-effectiveness. An optional box-type structure utilizes high-quality sheet metal and coatings to provide outstanding corrosion resistance. The enclosure features a rainproof and dustproof design to prevent ingress of rainwater, dust, and small animals.
