The experts have therefore also already examined the status of all those second-generation evo and third-generation power units that have been brought out since mid-2014 or in fact will only be appearing from the introduction of the new WLTP (Worldwide Harmonized Light Vehicles Test Procedure) emission standard from 1 September 2018.
On 1 September 2017, new emissions regulations for passenger vehicles come into force in the EU and Switzerland. Between 2009 and 2011 various workgroups were formed under the umbrella of the UN’s Economic Commission for Europe to develop a new emission-measuring method called the Worldwide Light Duty Vehicle Test Procedure (WLTP).
Much of the momentum for the shift originally came from the EU’s directive on mobile air-conditioning systems (MACs), which aims to reduce emissions of specific fluorinated greenhouse gases in the air-conditioning systems fitted to passenger cars (vehicles of category M1) and light commercial vehicles (category N1, class 1).
Stringent new emissions regulations in the US and Europe will require a substantial improvement in mobile emissions beginning in 2017. The novel material reaches operating temperature quicker than standard substrates, so catalytic converters can clean exhaust emissions earlier without increased fuel or additional precious metal.

However, although a CO 2 target of 70 g/km could be met without significant deployment of electric vehicles, the study found that exhausting all the potential gains from combustion engine technology improvements before transitioning to electric drive would be a relatively costly approach for vehicle manufacturers. Earlier post.).
Exhaust composition, however, changes rapidly enough for drivers to experience different conditions inside their vehicles than these roadside sensors. The chemical composition of exhaust changes very quickly, even in the space of just a few feet. Vreeland et al. Click to enlarge. —Heidi Vreeland, first author of the paper.
Fees that respond to traffic volumes in real time and with site precision, taking into account factors such as vehicle type and exhaust emissions, can significantly improve traffic flow and contribute to reducing air pollution, they suggest. A toll for road use would bring these costs to light and reduce congestion. That’s unfair.
Air drawn into the micro turbine is passed through a heat exchanger where heat from the exhaust air is transferred to the cold intake air, and compressed before it is ignited. As this hot exhaust gas is expelled, it passes through the heat exchanger to ensure the heat energy is recuperated and transferred to cold intake air.
