Control Strategies for Idle Speed of Automotive Engines

发动机怠速的降低将显著提高燃油效率。当前的技术是基于复杂发动机系统的简化模型，因此不能充分利用可能的控制器能力。因此，本项目提出了新的发动机模型，并将提供新的控制器方法来解决这个问题。对于LPG和汽油喷射发动机，这应有助于增加发动机稳定性和对干扰（如空调接合）的更快扭矩响应，从而允许降低发动机怠速而不冒失速或损害发动机噪声、振动和粗糙度质量的风险。

Reduction of engine idle speed will provide significant improvements in fuel efficiency. Current techniques are based on simplified models of a complex engine system and as a result do not fully exploit the possible controller capability. Therefore this project proposes new engine models and will provide novel controller methods to address this problem. This should contribute to increased engine stability and faster torque response to disturbances like air conditioner engagement, for both LPG and gasoline injected engines, thus allowing the engine idle speed to be lowered without risking stall or impairing the engine Noise, Vibration and Harshness quality.
