Research on diesel engine load distribution under the beijing district real - road driving cycle 北京地区实际行驶工况下柴油机负荷分布研究
Elimination of the conventional alternator reduces engine load , leading to better fuel efficiency 取消传统的交流发电机减少了发动机的负载,提高了燃油经济性。
In addition , the load index scheduling have simple realization , lessening the engine load as possible 另外,负载指数调度算法实现简单,尽可能减少了引擎负担。
Nevertheless , hcci also has its drawbacks . it is prone to misfire at the low engine load and knock at the high load . the operating range of hcci is narrow 但hcci发动机也存在着低负荷容易失火、高负荷容易爆震、工况范围狭窄、碳氢化合物和一氧化碳排放高等缺点。
Engine load simulated control system was consisted of two unattached parts of work resistance simulated control subsystem and electric eddycurrent dynamometer control subsystem 发动机负荷模拟加载控制系统包括彼此独立的作业阻力模拟控制子系统和电涡流测功机控制子系统两部分。
All in all , additives are beneficial to improve the ignition of hcci at low engine load and extend the operating range . nevertheless , the knock happens obviously while the range is extending at the high engine speed and load 总之,添加剂有利于改善hcci发动机低负荷着火和拓宽工作范围,但是在发动机高转速和高负荷工况下,在工况范围拓宽的同时, hcci爆震倾向明显,发动机工作不稳定。
In order to connect them and to let them dynamic response , mathematic models of engine load simulation controller were established , which transfer the work resistance ' s change to engine load change immediately , to meet the simulation control system 为了使它们有机地联接、动态响应,本文建立了发动机负荷模拟控制器数学模型,使作业阻力的变化及时转换为发动机负荷的变化,满足了仿真系统的控制要求。
At the conditions with the same fuel injection quantity per cycle and the same engine speed , with the increase of the additive mass fraction in the fuel , the ignition and heat release timings brought forward , the peak of heat release rate increased and the operating range at low engine load was enlarged obviously . however , excessive additives will make the engine be prone to knock , run rudely and shorten the operating range at high engine load 在相同循环喷油量和相同转速的条件下,随着添加剂质量分数的增加, hcci着火和燃烧放热提前,燃烧放热峰值提高,低负荷工况范围明显拓宽,但过高的添加剂质量分数会使得发动机爆震,工作粗暴,导致高负荷工况变窄。
The paper put forward three integrated control strategies adapting full of engine load , i . e . highest production efficiency control strategy , oil consume economic control strategy and give attention to the above control strategy . to aim at different task apply correspondent control strategy . so the simulation control study had practical purpose 提出了适应全负荷工况的三种综合控制策略:最高生产效率的控制策略、燃油经济性的控制策略和兼顾最高生产效率及燃油经济性的控制策略,针对不同的作业目的,应用不同的控制策略,使仿真控制研究具有实用的目的。
In this paper , the study was based on the emulational experience system of the tractor - implement . the emulational control system was composed of three parts : master pc monitor system , transmission and throttle control subsystem , engine load simulated control subsystem . using the system , many studies and experiments could be carried out on the implement units 本文的研究是在拖拉机作业机组仿真试验系统平台上进行,仿真系统的控制系统由上位机监控系统、发动机及换挡控制系统、发动机负荷模拟加载控制系统等三大部分组成,利用本控制系统能对机组进行各种加载试验研究。
