    Thermodynamic, performance and emission investigation of a diesel engine running on dimethyl ether and diethyl ether

    Sezer, Ismet

    This study investigates the use of dimethyl ether and diethyl ether in diesel engines as alternative fuels. A direct injection diesel engine was simulated via a thermodynamic cycle model for investigation. Thermodynamic and performance parameters besides emissions determined and compared for diesel, dimethyl ether and diethyl ether fuels at two different states. The results showed that dimethyl ether and diethyl ether presented a lower cylinder temperature and pressure, and thus a lower engine performance than diesel fuel for the equal injection conditions. The brake power declines about 32.1% and 19.4% at 4200 rpm while brake specific fuel consumption increases about 47.1% and 24.7% at 2200 rpm for dimethyl ether and diethyl ether, respectively. Engine performance for dimethyl ether and diethyl ether extensively improves for the same equivalence ratio condition, but a more amount of fuel is needed about 64% for dimethyl ether and 32% for diethyl ether. The gains in the brake power by dimethyl ether and diethyl are about 13.6% and 6% at 4200 rpm compared to diesel fuel. The brake specific fuel consumption is also higher about 43.5% for dimethyl ether and 23.6% for diethyl ether than diesel fuel. The brake thermal efficiency for dimethyl ether and diethyl is generally better than diesel fuel. The lower carbon dioxides are obtained by dimethyl and diethyl ethers at all conditions, while carbon monoxide and nitrogen oxide are slightly higher for dimethyl and diethyl ethers at equal equivalence ratio condition.

    Theoretical analysis the use of dimethyl ether and diethyl ether in a diesel engine

    Sezer, Ismet

    In this study, the use of dimethyl ether (DME) and diethyl ether (DEE) in diesel engines as alternative fuels investigated. A commercial suction (naturally-aspirated) direct injection (SDI) automobile diesel engine was chosen for investigation. Thermodynamic and performance analysis has been performed via a thermodynamic diesel engine cycle model. Thermodynamic and performance parameters computed and compared for diesel, DME and DEE fuels at two different situations. Results showed that DME and DEE presented the lower cylinder temperature and pressure, so a lower engine performance than diesel fuel for equal injection conditions. Brake power decreases about 32.1% and 19.4% at 4200 rpm while brake specific fuel consumption increases about 47.1% and 24.7% at 2200 rpm for DME and DEE, respectively. However, engine performance of DME and DEE extensively improves for the equal equivalence ratio condition, although more amount of fuel injection about 64 percent for DME and 32 percent for DEE is essential. The increments obtained by DME and DEE are about 13.6% and 6% in brake power at 4200 rpm compared to diesel. Brake specific fuel consumption is still higher about 43.5% for DME and 23.6% for DEE than diesel. Brake thermal efficiency of DME and DEE is generally better than diesel fuel.
