Abstract :
Short-term performance tests using crude palm oil (CPO) as fuel for a diesel engine showed CPO to be a suitable substitute of diesel fuel. However, prolonged use of CPO as fuel caused the engine performance to deteriorate. After 500 hours of cumulative running with CPO, the maximum power was reduced by about 20% and the minimum brake specific fuel consumption (bsfc) increased by about 26%. Examination of the different parts and tests revealed that the main reason for engine performance deterioration was `valve sticking´, caused by carbon deposits on the valve seats and stems.
