升降式止回閥
擁有多專業(yè)人才的研發(fā)中心，自許在閥門自動(dòng)化與驅(qū)動(dòng)科技領(lǐng)域中，成為業(yè)界創(chuàng)新的標(biāo)竿。伴演上？刂崎y領(lǐng)域?qū)I(yè)廠商，我們追求突破與創(chuàng)新的腳步永不中斷。每年所編列高達(dá)上千萬的預(yù)算，直接投入研發(fā)的深淵領(lǐng)域，專注在各類產(chǎn)品的研究開發(fā)。
公開了連續(xù)可變閥門持續(xù)時(shí)間(CVVD)的控制。一種用于通過對(duì)用于控制CVVD的致動(dòng)器進(jìn)行控制來控制CVVD的系統(tǒng)包括電子控制單元(ECU)，其被配置成根據(jù)車輛狀態(tài)來輸出用于控制致動(dòng)器的命令；凸輪位置傳感器，其被配置成測(cè)量凸輪每分鐘轉(zhuǎn)數(shù)(RPM)；以及控制器，其被配置成在與所述ECU通信的期間發(fā)生故障時(shí)根據(jù)所述凸輪RPM計(jì)算曲軸RPM，基于計(jì)算的曲軸RPM提取目標(biāo)相位角，并且將對(duì)應(yīng)于所提取的目標(biāo)相位角的電流輸出到所述致動(dòng)器。
