This paper studies the VOLVO B230F engine performance which is under idle speed conditions,by changing the size of the mass air flow sensor signal voltage,and real-time monitoring the change of the relevant data for the engine power,fuel consumption and exhaust gas,consequently,we can search the influence to the engine performance which the mass air flow sensor signal does.
This paper analyzes and discusses the noise generation and the influencing factors at the idle speed of engine,introducing effective measures for reducing noise according to the problems occuring in the course of receiving of 156FMI engine production.
It solved successfully long-term existent issues in pneumatic speed limiters of high idle speed, large power loss, and swinging of speed at home by means of designing the brand-new-in-structure valve-located device梒am-spring mechanism.
Since the electronic throttle was developed in the middle of the eighties of the twentieth century, it has gradually been applied on the advanced engines of the high-grade automobiles. Because the electronic throttle not only performs well on the fuel consumption and exhaust of motors, but also can realize the drive by wire, for example, idle speed control, traction control, cruise control, etc, it will be widely be applied in the future.
电子节气门技术自20世纪80年代中后期出现以来，已经逐渐应用到众多高中级轿车的先进发动机上，由于能有效的改善汽车的燃油经济性和降低排放，实现车辆的柔性控制(drive by wire)，其应用前景将越来越广泛。
During the process of automobile operation, because of some reasons, the valve plug of electronic-controlled injection system will choke up, it will make the stepping motor lose step and idle so that it will influence the control of gas discharge rate, therefore, sensor which is used to measure valve opening will play an important role in the system.
There are some idle intervals for network links during the execution of parallel applications, at which the links still consume large amounts of energy.
Operation modes are changed not instantaneously and the failures of the server in idle states occur in a Markovian flow.
The damage and, primarily, the corrosion cracking of austenitic welds is provoked by the steaming operations, as well as idle times due to repairs and other cases when corrosive condensates and deposits collected in the equipment.
amphitrite inhabiting the anthropogenic substrates only in the warm season: water works, idle vessels, and operational offshore vessels.
Dynamics of Restoration Processes in the Idle Solonetz Ecosystems in the Southern Transural Region
The paper described comstruction desigh character of carburetter Type TH201A,improvement of gasoline engine exhaustemissions at iale condition by means of modification comstruction design of carburetter idle system.Gasoline engine performance was also improved same time.
Based on a lot of matching optimization tests, the effect of the structural pa- ramenter of the injectors on the engine performance has been found, the optimum advanced injection characteristic has been established, and the effect of the fuel pumps with high injection rate on the idle performance of diesel engines are men- tioned in the paper, finally the assessment method is also proposed.
Four kinds of electronic controlled circuits in a forced idle fuel economizer for motor vehicles have been analysed and compared, the best one has been found among them for reasons of the fast response speed, high controlling accuracy, reliable actuation, simplicity and availability.
