An investigation of the performance of an electronic in-line pump system for diesel engines

WIT Electronic Fuel System Co., Ltd. has developed a new fuel injector, the Electronic In-line Pump （EIP） system, designed to meet China＇s diesel engine emission and fuel economy regulations. It can be used on marine diesel engines and commercial vehicle engines through different EIP systems. A numerical model of the EIP system was built in the AMESim environment for the purpose of creating a design tool for engine application and system optimization. The model was used to predict key injection characteristics under different operating conditions, such as injection pressure, injection rate, and injection duration. To validate these predictions, experimental tests were conducted under the conditions that were modeled. The results were quite encouraging and in agreement with model predictions. Additional experiments were conducted to study the injection characteristics of the EIP system. These results show that injection pressure and injection quantity are insensitive to injection timing variations, this is due to the design of the constant velocity cam profile. Finally, injection quantity and pressure vs. pulse width at different cam speeds are presented, an important injection characteristic for EIP system calibration.

企业文化建设与档案工作

在党的十五大精神指引下，随着我国社会主义市场经济体制的逐步建立和完善，许多企业都十分注重树立自我形象和企业精神。档案工作是企业文化建设的组成部分，如何把这两者有机结合起来，互相作用，以促进企业的发展，是当前探化企业改革，建立现代企业制度的需要，就此问题谈几点粗浅的认识。     

基于龚帕斯曲线法的高填方路基工后沉降预测新思路

引进一种新的沉降预测方法--龚帕斯曲线法,并同Duncan-Chang非线性有限元反析法及灰色系统理论并引入遗传算法放在同一工程实例中进行各种沉降预测的比较和分析,发现龚帕斯曲线法的沉降预测值最接近于实测值,其预测曲线与实测曲线吻合最好,且其误差也是最小的,绝大部分在1%以内.从而得出龚帕斯模型有更好的适应性,预测结果的离散性小及准确性高等优点,这对高填方路基的工后沉降预测提供了更可靠的方法,可推广应用于实践.
