Abstract
The present invention discloses a Hydrogen Fuelled Enhanced Combustion (HFEC) technology bases spark ignition engine (1) for genset applications. The HFEC technology based spark ignition engine (1) includes a hydrogen gas cylinder (2), a H2-PNG blender (3), a gas-train assembly (5), an electronic fuel control valve (6), a gas-air mixer (7), and an ECU (9). The H2-PNG blender (3) blends the hydrogen gas with the PNG to form H2-PNG fuel. The gas-train assembly (5) receives the H2-PNG fuel from the H2-PNG blender (3). The electronic fuel control valve (6) controls flow of the H2-PNG fuel to maintain an air-fuel ratio. The gas-air mixer (7) mixes the H2-PNG fuel with the air to form a gas-air fuel mixture. The ECU (9) maintains a fixed speed of an internal combustion engine (11) required to generate electrical output using the gas-air fuel mixture and generates a spark required for combustion.
