Many countries have decided to realize that biodiesel is one of the most effective strategy for reducing fuel's environmental effects. Researchers in each country are looking for more effective techniques and better selection of materials to produce better biodiesel. Malaysia is also one of the leading countries in the production of biodiesel. A diversity of studies has been performed on the effectiveness of biodiesel in diesel engine. Malaysia is considered to be one of the largest palm oil producers in the Asian, and Malaysia produces a significant proportion of its biodiesel from palm oil. However, biodiesel cannot be directly used on diesel engines because biodiesel's viscosity and density are greater than pure diesel. The effects of various additives used in biodiesel are studied by most researchers in such a way that their biodiesel properties are similar to or near the properties of diesel fuels. The main aim of this study is to investigate the influence of propanol and dichloromethane as an additive in Biodiesel/diesel blend as engine fuels on engine efficiency and the effect of the combustion of biodiesel additive on environmental emissions from the blend. The additive and biodiesel physicochemical properties are carefully discussed, which are the key determinants of the consistency of the blended diesel. The determination of this research is to assess the additive capacity of mixed biodiesel and diesel fuel in accordance with additive form, mixing ratio and engine operation conditions. The research aims to determine the efficiency and emissions as a biodiesel fuel mixture of a limited proportion of propanol (5 percent by volume) and dichloromethane (5 percent by volume). The four samples were prepared and tested with a single cylinder engine. Sample A (D 100) includes 100% diesel for comparison, sample B (D80POB20) diesel 80% and palm oil biodiesel 20%, sample C (D75POB20P5) diesel 75%, palm oil biodiesel 20% and propanol 5% and sample D (D75POB20DCM5) diesels 75% palm oil biodiesel 20% and dichloromethane 5%. Propanol and dichloromethane present in biodiesel blended fuel as an additives showed a lower percentage on exhaust emission of carbon monoxide, carbon dioxide, nitrogen oxide and hydrocarbon than biodiesel and pure diesel. While the engine power increase by using propanol and dichloromethane as an additive than biodiesel and decreases slightly than pure diesel and brake specific fuel consumption (BSFC) increases after use propanol and dichloromethane as an additive in Biodiesel/diesel blend as engine fuels
