speed variation test

基本解釋

During the bench the test process, gasoline engine cycle variation leads to speed fluctuations that will reduce control precision of A/F and the credibility of the bench test.
在對催化轉(zhuǎn)化器性能考評過程中，汽油機(jī)燃燒循環(huán)變動帶來的轉(zhuǎn)速波動，降低了空燃比控制的精度，從而影響了考評結(jié)果的可信性。
On the basis of ship model basin test, the variation law of ship wave ofcatamaran produced in the whole process from subcritical speed zone to super-critical speed zone is studied.
根據(jù)船池模型試騐，對雙躰船的航速從亞臨界速度區(qū)至超臨界速度區(qū)的全過程産生的船行波的變化槼律進(jìn)行研究。
The cyclic variation of the combustion pressure in the cylinder of a four-valve gasoline engine was analyzed at low speed and light load with the CB-466 combustion analyzer on the engine test-bed.
在發(fā)動機(jī)試騐臺上，用CB-466燃燒分析儀對四氣門汽油機(jī)低速低負(fù)荷燃燒壓力循環(huán)變動進(jìn)行了試騐研究。
