Summary:

The benefits associated with the use of oxygen-containing diesel fuels in passenger cars are quite well described in the literature. The described tests used oxygen components belonging to such chemical groups as, for example, glycol ethers, maleates, carbonates, and higher alcohols. This work describes the results of a 18-meter EEV city bus fueled with diesel fuel with the addition of 10% v/v of triethylene glycol dimethyl ether. This compound was chosen because it was effective in reducing exhaust emissions from light duty diesel cars. Emission tests (CO, HC, NOx and PM) of the city bus were performed in SORT (standardized on-road tests) cycles using portable exhaust gas analyzers PEMS. Significant differences in the emission of exhaust components were observed in individual SORT cycles. The level of road emissions reduced as the traffic smoothness increased, id est from the SORT 1 to SORT 3 cycle. The largest reduction in bus emissions associated with the use of the oxygenated additive (triethylene glycol dimethyl ether) applies to carbon monoxide and ranges from 50% for the SORT 3 cycle up to 90% for the cycle SORT 1. For the other exhaust components, the changes caused by the use of triethylene glycol dimethyl ether were much smaller
