Context 1
... a test period of about 2 months the VW Caddy Maxi was operated under realistic operating conditions following the drive cycle as shown in Table 9. Each case represents a different driving behavior. ...
Context 2
... case represents a different driving behavior. During the experiments, dynamometer was set at a fixed the speed (corresponding to a certain engine load) and rpm for one day (for example 40 km/hour and 2500 rpm, case 1 see in Table 9). ...
Context 3
... next day we changed the speed and rpm representing a different part of the drive cycle (for example case 2 in Table 9). In this way the complete drive cycle is simulated during one week. ...
Context 4
... two months of testing, 50 grams SiO2 was produced but there was still no irreversible failure of the lambda sensor or degradation in NOx or CO conversion in the catalyst observed. As a final test, the VW Caddy Maxi was tested for the duration of one week (one drive cycle in Table 9) using a siloxane concentration of 74 mg Si/m 3 n. The total amount of SiO2 produced at the end of the test was 70.9 grams (including the 50 grams produced in the two preceding months). ...
Context 5
... 32: Lambda signal from wide band (in front of catalyst) and switching (after catalyst) type lambda sensors measured during 40 km/hour and 3 rd gear test (see Table 9) ...
