Auto parts supplier BorgWarner raised its full-year adjusted profit outlook on Thursday, aided by sustained demand from its exhausts, turbos and emission control systems. The company has benefited from automakers rushing to put out vehicles with smaller engines that are powerful and meet modern emission norms.

the E30 and E78—led to statistically significant reductions of 9%–13% for total hydrocarbon (THC); 13%–44% for non-methane hydrocarbon (NMHC); 20%–35% for carbon monoxide (CO); and 17%–36% for nitrogen oxides (NO x ) emissions compared to the high-aromatics E10 fuel. The study found that higher ethanol blends—i.e., Durbin, Kent C.

Although past studies have provided substantial insight, important gaps remain in our understanding of SOA formation from gasoline vehicle exhaust due to changing engine technology and emissions certification standards. Finally, we evaluate the use of an OFR as screening tool for SOA production from on-road gasoline vehicle exhaust.

The researchers used a Horiba OBS-2200 portable emissions measurement system (PEMS) to measure gaseous exhaust emissions, including NO x , carbon monoxide (CO), carbon dioxide (CO 2 ) and total hydrocarbons (THC) on a continuous basis. Overall, urban/suburban driving leads to a 32-39% reduction in fuel economy over highway driving.

The Gen III Prius offers an EPA-rated combined cycle fuel economy of 50 mpg (now revealed to comprise 50 mpg city and 49 mpg highway). This is about a 10% improvement in EPA-rated combined cycle fuel economy over the older generation. An exhaust gas recirculation (EGR) system has also been added. Click to enlarge.
