摘要：

Gaseous fuels such as CNG and hydrogen are promising alternative fuels which receive more attention all over the world. This paper investigates the effect of compressed natural gas (CNG) and 18% hydrogen blended compressed natural gas (HCNG) on a retrofitted gasoline genset engine's performance, emissions, deposits and lubricants under long duration testing. During the 60 h test, lower BSFC, CO and HC are observed for HCNG with the penalty of NOx values. The deposits of iron on spark plug and cylinder liner are higher for HCNG compared to CNG. As kinematic viscosity and TBN values of lubricant decreased significantly with HCNG, it has resulted in higher concentration of wear metals (iron and copper) in the used oil.
