Abstract

Cassava biogasoline was tested on electronic fuel injection vehicles in urban traffic conditions with varying engine load. Biogasoline tested includes B0, B10, B20, and B30. The engine speed was operated within 750 to 1800 rpm (low-speed range) to simulate urban traffic condition. The engine load was varied through the operation of air conditioner (AC). Fuel consumption was measured in real terms (ml/s) and CO emissions were measured with the Hesbon HG 520 Engine Gas Analyzer (EGA) in the percentage of total exhaust gas. The results showed that B10 has the lowest fuel consumption of 0.24 ml/s in conditions without AC and 0.41 ml/s with AC. Meanwhile, CO emissions tend to be constant with change in the proportion of cassava biogasoline and increased with additional AC load.

Abstract

Utilization of crude palm oils (CPO) as biodiesel faces difficulty due to their high level of viscosity. Mixing crude eucalyptus oils (CEO) with CPO may reduce the viscosity due to the presence of aromatic compounds in CEO. The single droplet analysis was performed to determine the characteristics of mixing CPO with the CEO. The results showed that the addition of CEO decreased the viscosity due to the presence of intermolecular attractions, thereby leading to more active molecules in the CPO-CEO mixture. Furthermore, the aromatic compound in the CEO helped in decreasing the CPO flash point, while the aromatic compound in the triglyceride molecule weakens the bonds between molecules. The addition of CEO to CPO tends to reduce the ignition delay due to the presence of cineol content in the CEO, which weakens the van der Waals bond in CPO.
