Performance analysis of a diesel engine operated by biodiesel blends prepared from waste cooking oil

Abstract EN

The Biodiesel was prepared from waste vegetable cooking oil that was collected from potato chips factory.

It was prepared at the laboratories of faculty of Science Ain Shams University by transesterification method.

The oil was filtered and heated, then methanol was added in the presence of potassium hydroxide as a catalyst.

Several blends of biodiesel and mineral diesel were produced to be used in this study: B0, B10, B20 and B30 respectively.

These blends were used to operate a single cylinder air cooled diesel engine of model: Deutz (F1L511) to analyze its performance and emissions.

The thermal efficiency was improved when the blend B20 was used.

The exhaust gases temperature increased by increasing the blending ratio.

The carbon monoxide (CO) emission was decreased by increasing the blending ratio.

The nitrogen oxides (NOx) emissions were increased by using biodiesel blends.

The best performance of the engine was obtained by using the blend B20.
