Abstract

Turbulent jet ignition is an important method to achieve lean combustion in spark ignition engines by using a pre-chamber to ensure reliable ignition and a high burning rate. In this work, a TJI device is designed with additional fuel supply in the pre-chamber, the combustion characteristics of TJI are analyzed, and its operation strategy optimization over wide engine loads is performed on a single-cylinder engine. The results show that a stable combustion process with an excess air coefficient in the range of 1.0–2.2 is achieved, reducing the fuel consumption rate by up to 9.6% under a part load compared with that of the baseline engine. However, under high loads, lean combustion cannot effectively maintain the required power output, and under low loads, excessive lean combustion results in a significant reduction in the combustion efficiency. Therefore, a technical solution involving different intake strategies for different loads, including intake boost, Miller cycle, throttle adjustment, and negative valve overlap, is proposed to flexibly regulate the air/fuel ratio and maintain the in-cylinder excess air coefficient in the optimal range (1.5–2.0). The results show that the fuel consumption rate of boosted lean combustion strategy is reduced by 10–12.5% under high loads compared with that of the baseline engine. Under medium-to-low loads, a reasonable intake strategy reduces the intake air mass and helps avoid excessive lean combustion, and the fuel consumption can be reduced by more than 9.6%. The present work demonstrates the potential of TJI application to enhance the thermal efficiency through lean combustion.
