“…Hands et al later modified this CO 2 [15] sensor to make a fast response (7ms response time) CO sensor. Under rich cold-start conditions the CO sensor allows a faster estimate of stoichiometry than the UEGO sensor.…”

“…He studied the real time NO emis sions emit ted from the cyl in der and ex haust valve on SI en gine equipped with the real time NO de tec tion. Hands [9] stud ied the real time NO, CO, and HC emis sions dur ing the first 505 sec onds of the FTP75 on four cyl in ders SI en gine. So far, no pa per were puplished about the real time NO emis sions dur ing cold start.…”

“…The system has two sample heads, each measuring CO and CO 2 simultaneously and therefore four analogue outputs are available. The response time of the system is less than 8ms (10-90%), while it is achieved by miniaturizing the sampling system [98,111,112]. The first channel measured cyclic resolved cylinder exhaust port concentrations while the second one measured averaged concentrations just upstream of the exhaust muffler.…”
