摘  要：
应用VP37电控分配泵管理系统与CA498Z型柴油机所组成的电控CA498Z型柴油机和与该管理系统相匹配的VS100标定系统,试验研究了进气预热条件下起动结束标志转速对电控柴油机起动性能的影响规律,得出了进气预热条件下电控柴油机起动油量脉谱优化的一般过程,证明发动机固有特性决定了起动阶段的结束点到起动脉谱油量的延迟作用终点前的发动机转速升高率极限值。

摘  要：
Tests were done to research the influence of intake preheating during start process for electronic controlled diesel engine by using the electronic controlled diesel engine which was combined with VP37 electronic controlled distributor type injection pump management system and VS100 demarcate system.Tests were done to research the end symbol rotate speed of start,which influenced the performance of electronic control diesel engine during start process.Optimization process of fuel supply map during start process was drawn under the condition of intake preheating through the tests.The conclusion was also reached——the limit data of engine's speed increased during the period between end of start phases and effective terminal of start fuel supply map was decided by the engine's inherent characteristic.
