Why is it not enough?
The EASYDIAG® 5 gases analysis visualizes engine drifts that set in without the knowledge of the driver, who is getting used to the reduced performance of his car. It compensates for this loss of efficiency by accelerating more to drive at the same speed. (Increase in CO2) These functional drifts do not necessarily light up an engine warning light, they are therefore invisible to the electronic suitcase used by automotive professionals and are not reported to the motorist during maintenance of his vehicle. However, the maintenance has to be adapted according to the use of the car, especially if the driver drives in the city or on short trips, with a diesel for example.
What differencies with the 5 gases analysis?
Diesel : Technical inspection standards do not measure gases (O 2 , CO 2 , CO, HC, NOx) but only smoke opacity, or in some countries, particle counting in order to verify the presence of the particle filter.
Gasoline : The technical control standards measure only one gas, the CO and the lambda ratio. Gases such as HC and NOx are forgotten….
Why are they not implementing the 5 gases measure?
Because the authorities do not have the "5gaz benchmarks" in static measurements and have no history of data by technology and analysis. Indeed, more than 20 years ago, nobody cared to change the standards of technical control and the "dieselgate" did not exist at that time. The only known reference measurements were those of the homologation in rolling cycle (NEDC and WLTP) not reproducible in a workshop or via technical control.
Conversely, ECOSPHERE and its Motorist partner SPHERETECH Environnement have been collecting thousands of 5 gasses measurements of the vehicle fleet since 1998. They have the values of sufficient references to be able to act effectively on the vehicle fleet through predictive maintenance.
Independent Observatory of the fleet, SPHERETECH Environment has become an active contributor to European equipment manufacturers (BOSCH, AVL) and certain ministries wishing to act for the environment because the thermal vehicle fleet before our eyes is huge and very present for long years.
The authorities still consider that a modern Euro 6 car remains within its homologation level over time while, depending on its use, a poorly maintained Euro 6 can pollute more than a Euro 5 in good condition….
Some European states are now showing a real interest in taking advantage of our technology to implement ECODIAG-type measures, following growth rapid development of low-emission zones and the constraints they entail.
