德国Kaiserslautern理工大学和Karsruher工艺技术研究所介绍了进一步降低汽油机燃油耗和二氧化碳排放的可能性及其极限,评价和比较了以化学计量比均质混合气运行的汽油机,并使用了可变气门机构优化工作过程的热力学方法。为此,将划分凸轮轴相位调节器、非连续气门升程转换器和全可变气门系统之间的应用界限。此外,还介绍了汽油机无节流运行中气缸切断的节油潜力。
The German Kaiserslautern Institute of Technology and Karsruher Institute of Technology introduced the possibility and limits of further reducing the fuel consumption and the carbon dioxide emission of gasoline engines. The gasoline engines running with stoichiometric homogeneous mixture were evaluated and compared. The variable valve train Thermodynamic method to optimize working process. To this end, the application boundary between camshaft phase adjusters, non-continuous valve lift converters and fully variable valve systems will be divided. In addition, the fuel-saving potential of cylinder shut-off during gasoline-less throttling operation is also described.
