UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

JUNE 12, 2023

A study by a team from UC Riverside has assessed the potential of increasing ethanol content in California reformulated gasoline (CaRFG) by investigating the exhaust emissions from a fleet of 20 Tier 3 light-duty vehicles. Formaldehyde emissions did not show a statistically significant effect. Durbin, Kent C. 2023.128836.

The ECM controls the air/fuel ratio (AFR) by measuring the voltage generated through the oxygen sensor which indicates the proportion of oxygen in the exhaust. Furthermore, a similar comparison was implemented on coolant temperatures. sensor readings for the two conditions were similar. from vehicles running on each fuel type.

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Small particles in exhaust from burning fossil fuels creates “seeds” on which water vapor in the air can condense into cloud droplets. C, or 1.8 ?F, F, since the late 1800s.).

This statistic increases to two-thirds of all new registrations if the data are restricted to passenger cars, according to Bosch. A recent example is the Chevrolet Cruze, for which Bosch supplies the diesel fuel injection system along with the exhaust-gas treatment system, engine control system, ceramic spark plugs, and sensors.

According to statistics compiled by the German Motor Vehicle Registration Authority cited by BMW, the average fuel consumption of all BMW and MINI vehicles registered in Germany in 2008 is 5.9 The volume and temperature of exhaust gas may be determined precisely as a function of current running conditions and the temperature of the engine.

There are two basic exhaust emissions and fuel economy tests described in J1711. Calculations are provided that combine the CD and charge-sustaining (CS) behavior according to in-use driving statistics. Earlier post.) One test begins with operation assumed to be CS for HEV operating modes: the Charge-Sustaining Test (CST).

Among the findings from the study: For vehicles certified to the same emissions standard, there is no statistical difference of regulated gas-phase pollutant emissions between PFIs and GDIs. Therefore, the secondary organic aerosol and ozone formation potential of the exhaust does not depend on engine technology. of the data.

The few effects that were reported for the rats were mild hyperplasia (cell proliferation) in the lungs and slightly reduced lung function, and were most consistent with exposure to nitrogen oxides in the engine exhaust, which are being further reduced under 2010 US EPA standards now in effect.

Its heart is the exhaust manifold integrated into the cylinder head. It quickly warms up the engine following a cold start, and at high load the water jacket reduces the temperature of the exhaust gas.

The data presented in these studies did not show any evidence of deterioration in engine durability or maintenance issues for E15 (or E20) in comparison to E0 and E10 (when tested). Materials compatibility testing provides no evidence that 15 vol% ethanol blends will cause increased rates of metal corrosion in comparison to 10% blends.
