Euro 7 emissions standards – a barrier to gasoline and diesel vehicles

Euro 7 will continue to reduce harmful emissions to the environment as much as possible and is expected to come into effect as early as 2025.

Carmakers are worried and contend that upcoming Euro 7 emissions standards will increase production costs, to the point where it won’t be profitable if the car doesn’t have a plug-in hybrid system or a fully powered engine. by electricity.

So the future of the internal combustion engine will become blurred. One document shows that Euro 7 will push the nitrogen oxide (NOx) level down to 30 milligrams / km (the airborne emission standard mg / km). By today’s standards, this is well below the lowest margin of error seen on portable flue gas measuring systems.

In January 2021, the Euro 6d standard will mandate vehicles to emit no more than 80 mg / km, on tests as well as in actual conditions. This level does not include the margin of error per portable emissions units, estimated to be 34.4 mg / km maximum.

A senior engineer at Volkwagen stated that, if the Euro 7 proposals from the consulting group on EU vehicle emissions standards come into effect, the German carmaker will no longer have the ability to sell one. Small Polo with a minimum price of 18,000 USD.

“If they don’t extend the conditions of the test to include exhaust emissions testing while driving uphill while pulling a trailer, that would be the end of dynamic cars,” said one car engineer. “The internal combustion engine and even the car using the sub-48V light hybrid engine can’t meet such low requirements in all situations.”

The engineer went on to say: “We will have to remove the manual to set the exact timing of the gearshifts and acceleration. Driving will need to follow a computer program to reduce the maximum amount of acceleration. emissions and driving will lose the fun. “

Creating clean electric and fuel cars is a step up, but not everyone can afford a new hybrid or electric car.

“People for whatever reason cannot switch to electric cars, they keep their existing cars, instead of replacing them with cleaner ones,” said engineer Volkwagen.

This scenario would actually increase harmful emissions, at least in the short term. Meanwhile, the environmental protection team, says that the Euro 7 technical targets will have to be set close to 0 mg / km to take into account the measurement tolerance.

“There is no evidence that the 30 mg / km NOx limit is technically feasible at this time, especially for all forms of on-road driving. The same limit would have to be. respond to a range of harsher driving conditions, including altitude, high speeds, uphill driving, heavy duty driving, and harsher summer and winter conditions.
