Roll-on test bench\u00ades are an impor\u00adtant tool for func\u00adtion\u00adal test\u00ading in the auto\u00admo\u00adtive indus\u00adtry. The soft\u00adware from rd elec\u00adtron\u00adic enables mul\u00adti\u00adple tasks to be per\u00adformed sequen\u00adtial\u00adly on a sin\u00adgle test bench. This includes the unique inte\u00adgra\u00adtion of an engine hot test.<\/p>\n\n
After assem\u00adbly, 100% of inter\u00adnal com\u00adbus\u00adtion engines under\u00adgo a cold test. Dur\u00ading the cold test, the engine is filled with oil but not with coolant and is dri\u00adven by the test bench. Torque, leak tight\u00adness, and air mass are mea\u00adsured dur\u00ading this process. To val\u00adi\u00addate the cold test, the first n engines of a new engine series under\u00adgo a hot test. This means the engine is ful\u00adly sup\u00adplied with oper\u00adat\u00ading flu\u00adids and fired up. Dur\u00ading this process, the engine dri\u00adves the hot test bench. The goal is to iden\u00adti\u00adfy any gaps in the test cov\u00ader\u00adage of the cold test in order to close them.<\/p>\n\n
Like the cold test, the hot test is con\u00adduct\u00aded at the engine plant.<\/p>\n\n
In \u201cCom\u00adplete\u00adly Knocked Down\u201d engine pro\u00adduc\u00adtion, hot test bench\u00ades are not always avail\u00adable at the CKD engine plant. Ship\u00adping the engines by air freight for hot test\u00ading is expen\u00adsive and time-con\u00adsum\u00ading. To reduce costs and time, the engine hot test is per\u00adformed at the CKD vehi\u00adcle assem\u00adbly plant. Here, the engine is test\u00aded on the roller test bench while installed in the vehi\u00adcle. In addi\u00adtion to the afore\u00admen\u00adtioned sav\u00adings, this also elim\u00adi\u00adnates the set\u00adup and tear\u00addown effort for the hot test engine test bench and the sim\u00adu\u00adla\u00adtion of the vehi\u00adcle elec\u00adtri\u00adcal system.<\/p>\n\n
Bat\u00adtery-pow\u00adered elec\u00adtric mobil\u00adi\u00adty will large\u00adly replace inter\u00adnal com\u00adbus\u00adtion engine tech\u00adnol\u00ado\u00adgy. How\u00adev\u00ader, the inter\u00adnal com\u00adbus\u00adtion engine is not expect\u00aded to dis\u00adap\u00adpear entire\u00adly. For this future sce\u00adnario, rd elec\u00adtron\u00adic offers a solu\u00adtion that allows new or old\u00ader roller test bench\u00ades to be upgrad\u00aded to ful\u00adly and com\u00adpre\u00adhen\u00adsive\u00adly test the small\u00ader vol\u00adumes of inter\u00adnal com\u00adbus\u00adtion engine vehicles.<\/p>\n\n
rd elec\u00adtron\u00adic is cur\u00adrent\u00adly test\u00ading the hot-run soft\u00adware on roller test bench\u00ades in col\u00adlab\u00ado\u00adra\u00adtion with an inno\u00adv\u00ada\u00adtive Ger\u00adman OEM.<\/p>\n\n
