This paper investigates the effect of performance and exhaust emissions test results from a liquid propane injected engine with hydrogen enrichment. In order to research this topic, the test engine was run at 1400 rpm with a compression ratio of eight. Relative air-fuel ratio varied between 0.8 and 1.3. CO emissions decreased with the addition of hydrogen, but the oxygen amount decreased around the rich and stoichiometric air-fuel ratio as the hydrogen supplement rate increased. CO2 emissions decreased with the increase in the hydrogen supplement rate. Total hydrocarbon (CH)emissions decreased as hydrogen was added in the rich and around stoichiometic air-fuel ratio. NOx emissions were maximum at around lambda = 1.2 and the addition of 20 per cent hydrogen resulted in about a 20 per cent increase in the amount of NOx emissions compared to that of pure LPG (liquified petroleum gas) combustion. Power and thermal efficiency increased with the decrease of the hydrogen supplement rate.
