The FFV engine technology that uses ethanol is emerging as a new paradigm for an alternative energy powertrain. In this study, the combustion and performance characteristics of a 1.0 L TGDI-FFV engine were analyzed when gasolineethanol fuels with various blending ratios were used. Under the test conditions, engine performance improved after optimizing the spark timing. In particular, improvements in the torque of E30 and E50 fuels were 5.3 % and 7.8 %, respectively, without affecting combustion stability. The ignition timing of the E30 and E50 fuels was further advanced from the stock timing, reducing BSFC by about 3.6 % for E30 fuel, and 6.8 % for E50 fuel. Optimization of the combustion characteristics was possible with the ignition timing control to MBT for the FFV engine, resulting in improved torque and BSFC. Consequently, the authors suggest the necessity of improving the spark timing control strategy for the FFV engine. |
