Abstract

If the agricultural products market is limited and much of agricultural land is not utilized as is the case in many countries in the world at present, then agriculture should be directed to the production of new alternative products. The land can be used to produce non-food products including biofuels for the domestic energy market to diminish imports. Much research has been conducted on biofuels over the last 20 years. At present, concern about environmental regulations, green house gases and fossil fuel reservartion (including natural) have been the major reasons to look for alternative fuels that come from renewable resources. A significant level in terms of physico-chemical properties of biofuel has been obtained mostly from methyl ester of food based vegetable oils; it is now the issue to be concerned about human food oil versus biofuel production. This paper presents the experimental results carried out to evaluate performance and exhaust emissions of a diesel engine operated on “Envo Diesel” which consists of 5% palm oil and 95% ordinary diesel fuel ( as P5). The Envo diesel is a policy of Malaysian governmnet that emphasises on usage of waste palm oil with diesel fuel without esterification. This investigation also includes a benchmarking study with 5% coconut oil with 95% diesel fuel (as C5). However, all the results have been compared with pure diesel fuel (B0). The results show that fuels P5 and C5 reduce brake power 1.2% and 0.7% respectively as compared to B0. However, both the fuels P5 and C5 reduce exhaust emissions such as reduce HC, smoke, CO and NOx concentration. The paper contains the test results, properties of P5 and C5 biofuel and comparison with other biofuels that obtained from various vegetable oils.The results of this investigation will be used to find compatible lubricant/additive for biofuel operated engines.
