In 2020 the California Air Resources Board (CARB) implemented even more stringent regulation of vehicle emissions, its low-emission vehicle III (LEV III) program. In a (P)HEV T-GDI vehicle, the vehicle operates in EV driving mode when the engine is off, making it similarly difficult to comply with evaporative gas regulations. Automotive OEM strategy development to reduce vehicle evaporative gas and exhaust gas is in progress as these new emissions regulations are being implemented. Unlike in a naturally aspired engine, in a turbo gasoline direct injection (T-GDI) engine, the main operating area is the turbo boosting area. It operates in the positive pressure area rather than the negative pressure area, making it difficult to meet the requirements of the new evaporative gas regulationsI. The (P)HEV T-GDI characteristics showed the evaporative gas standards of LEV III, as well as regulations on CO₂, fuel efficiency, and exhaust gas. 2.0 T-GDI single purge system vehicles showed 1.8 times engine operation time test results satisfied with evaporative gas test regulation values. Additionally, exhaust gas emissions in hot mode showed that CO(g/mile) affects 2.0 L T-GDI vehicles 2∼3 times more than 3.0 L V6 T-GDI dual purge system vehicles. Fuel efficiency test results, confirming that the 3.0 V6 had about 15 % FTP, 20 % HWY, 18 % US06 better fuel efficiency compared to the 2.0 L T-GDI vehicles. Furthermore, the properties of the operating lines optimized for two plug-in hybrid turbo charger systems to assess whether they can meet the evaporative gas standards of LEV III, as well as regulations on CO₂, fuel efficiency, and exhaust gas. The 2.0 L T-GDI vehicle bears fuel economy loss, increases the engine operating time, and responds to the regulation of evaporative gas, and the 3.0 V6 confirms that the engine operating time, fuel economy, exhaust gas, and evaporative gas are optimized. To respond to LEV III evaporative gas regulations, 2.0 L T-GDI PHEV vehicles take longer engine operation time, fuel economy loss, and respond to evaporative gas, CO₂, emission regulations, 3.0 L V6 T-GDI PHEV vehicles confirmed that engine operation time, fuel economy, exhaust gas, and evaporative gas were optimized. They can meet the evaporative gas standards of LEV III, as well as regulations on CO₂, fuel efficiency, and exhaust gas.

2020 年，加州空气资源委员会 (CARB) 实施了更严格的车辆排放法规，即其低排放车辆 III (LEV III) 计划。在 (P)HEV T-GDI 车辆中，车辆在发动机关闭时以 EV 驱动模式运行，因此同样难以遵守蒸发气体法规。随着这些新排放法规的实施，汽车 OEM 战略制定以减少车辆蒸发气体和废气。与自然吸气发动机不同，在涡轮汽油直喷 (T-GDI) 发动机中，主要工作区域是涡轮增压区域。工作在正压区而不是负压区，难以满足新蒸发气体法规I的要求。₂、燃油效率和废气。2.0 T-GDI 单吹扫系统车辆显示 1.8 倍发动机运行时间测试结果满足蒸发气体测试规定值。此外，热模式下的废气排放表明，CO(g/mile) 对 2.0 L T-GDI 车辆的影响是 3.0 L V6 T-GDI 双吹扫系统车辆的 2~3 倍。燃油效率测试结果，证实与 2.0 L T-GDI 车辆相比，3.0 V6 具有约 15% FTP、20% HWY、18% US06 更好的燃油效率。此外，针对两个插电式混合动力涡轮增压系统优化了运行线的特性，以评估它们是否能够满足LEV III的蒸发气体标准以及CO _{2 的}规定、燃油效率和废气。2.0升T-GDI车型承担燃油经济性损失，增加发动机运行时间，响应蒸发气体调节，3.0 V6确认发动机运行时间、燃油经济性、尾气、蒸发气体均得到优化。为应对LEV III蒸发气法规，2.0 L T-GDI PHEV车辆需要更长的发动机运行时间，燃油经济性损失，并响应蒸发气、CO ₂排放法规，3.0 L V6 T-GDI PHEV车辆确认发动机运行时间、燃油经济性、废气和蒸发气体都得到了优化。它们可以满足LEV III的蒸发气体标准，以及CO ₂、燃油效率和废气的规定。
