Real driving emissions (RDE) field test with a load
Channel: Johan Joubert

The first in a series of ten field tests monitoring the Road-Rail Vehicle (RRV) using the Portable Emissions Measurement System (PEMS) on the standardised C-route. But, different to the first set of field tests, we now measured emissions under various loads. In this video, we were busy with the ensemble of field tests using 1.5t. The SEMTECH DS+ PEMS unit from Sensors Inc is the first of its kind in (South) Africa. 

The vehicle is an Isuzu 850 FTR AMT (automatic) with a 7.8 litre, in-line six-cylinder turbocharged diesel engine. A real pleasure to drive and typical in an urban logistics setting. It is rated as a EURO 3 emissions vehicle. In this video you can see the real-time and accumulated emissions, along with the vehicle speed, engine revolutions and a reference map. 

The first portion is recorded at normal speed, and from around 04:40 we speed things up. Best to watch the video in 1080p HD.

And yes, you might note that at (too) many intersections we are experiencing what is known in South Africa as "loadshedding": scheduled periods where there is no power (also not for traffic signals). At 07:43 there are some formal Outsurance pointsmen. At 13:38 you can see volunteers, self-appointed traffic officers who step up and help regulate traffic at busy intersections. See if you can calculate what percentage of traffic signals were not functioning on this trip, and comment below.
