Diesel engines are widely used for commercial vehicles due to their high efficiency. However, oxides of nitrogen (NOx), carbon monoxide (CO) and unburned hydrocarbon (UHC) emissions of diesel engine cause a negative impact on public health and environment. Using butanol as additive for diesel is one way to reduce diesel engines emissions. This paper investigates diesel engine performance of 10% and 20% butanol (B) blended with diesel fuel. Engine performance such as brake power (BP), brake-specific fuel consumption (BSFC) and in-cylinder pressure were measured. Exhaust gas emissions such as NOx, CO and UHC were also assessed and compared with conventional diesel as baseline. The test was carried out in a single-cylinder direct injection (DI) diesel engine at three engine speeds (1400, 2000 and 2600 rpm) at full load. The experimental results revealed that: BP of butanol-diesel blends was comparable with neat diesel at low and medium engine speeds, while the peak in-cylinder pressure was higher compared to diesel at medium engine speed. Exhaust gas temperature (EGT) and NOx emissions were reduced as a result of the addition of butanol to the diesel blend, while UHC emissions were slightly increased. CO emissions were significantly reduced due to butanol-diesel blend has high oxygen content.
