In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

At the same time, ‘Motor’ is in our company name and we accordingly have a strong passion for and level of commitment to the internal combustion engine. Earlier post.).
There are widespread policy assumptions that the phase-out of gasoline and diesel internal combustion engines will over time lead to much reduced emissions of Volatile Organic Compounds (VOCs) from road transport and related fuels. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,
An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption. This is done via exhaust gas recirculation (EGR). —Patrik Soltic. The first results are very promising.
the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.
Exhaust from on-road diesel vehicles was responsible for nearly half of the impacts (~181,000 premature deaths) worldwide, and fully two-thirds in India, France, Germany, and Italy. Consideration of these impacts would likely increase the estimate of health impacts from vehicle exhaust emissions. Transportation-attributable PM 2.5
Schlumberger has entered into an agreement with RTI International , a nonprofit research institute, to accelerate the industrialization and scale-up of its proprietary non-aqueous solvent (NAS) technology, which enhances the efficiency of absorption-based carbon capture.
Known internally and to Volkswagen enthusiasts as the “Evo4,” its two most difficult roles might be under the hood of the 2022 Golf GTI and R. The EA888 utilizes a unique exhaust manifold design that is completely contained inside the cylinder head; it can thus be said that the compact turbocharger mounts directly to the engine.
Toyota introduced the next-generation three-row 2020 Highlander SUV at the New York International Auto Show. The gas engine employs Variable Valve Timing-intelligent system by Electric motor (VVT-iE) on the intake camshaft, and VVT-i on the exhaust camshaft.
liter diesel, prominently showing the closely attached exhaust aftertreatment system. For example, depending on the emission requirements, 3 different types of exhaust gas recirculation (EGR ) can be used: cooled high-pressure EGR without low-pressure EGR; cooled low-pressure EGR without high-pressure EGR; or. The exhaust side systems.
The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. First, the vehicle’s flue gases in the exhaust pipe are cooled down and the water is separated from the gases. Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%.
The cylinder head features an integrated exhaust manifold that separates the inner and outer pairs of cylinders into each inlet passage to the turbo. Keeping the exhaust pulses separated from the next cylinder in the firing order eliminates mixing losses and maximizes pulse energy to the turbine wheel. Larger exhaust valves.
New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., A scrubber is used on ships to clean exhaust gases, primarily to reduce emissions of sulfur oxides to the atmosphere. —Erik Ytreberg.
Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Because the intake and exhaust ports are at the opposite ends of the cylinder, opposed-piston engines have efficient, uniflow scavenging. Scavenging continues until a 230° crank angle, at which time the exhaust ports close.
These agencies, in concert with other national and international regulators, seek to significantly reduce greenhouse gas (GHG) emissions and harmful air pollutants produced primarily by heavy-duty trucks, vans and buses.

A paper on their study is published in the International Journal of Engine Research. Reactivity-controlled compression ignition combustion phasing (CA50—crank angle when 50% of fuel is burned) is most sensitive to variations in diesel fuel mass, level of exhaust gas recirculation, and charge gas temperature.
Late-phasing homogeneous charge compression ignition operating conditions have the potential to expand the useful operating range of homogeneous charge compression ignition in internal combustion engines. However, significant combustion instabilities can occur at late-phasing operating conditions.
Southwest Research Institute (SwRI) is helping a client develop a simple post-refinery treatment process that reduces exhaust emissions from diesel engines by overcoming the soot/nitrogen oxides (NO x ) reduction trade-off that has plagued engine researchers for decades.
However, practical challenges still exist when applying ammonia in traditional internal combustion engines (ICEs) due to its high ignition energy, slow flame propagation and significant NO x emissions. Ammonia is a promising carbon–neutral fuel, able to power heavy-duty vehicles, non-road machineries and ocean ships with zero CO 2 emission.

Placement of the M936NGT in the Daimler commercial vehicle engine portfolio.
It expands all the way to ambient pressure before the exhaust stroke. The power is produced in almost a 50-50 split between the combustion (central) and exhaust (largest) pistons. Transfer from the combustion cylinder to the exhaust cylinder takes place when the exhaust cylinder volume is minimal. Clarke and W.
