Ammonia exhaust emissions from spark ignition vehicles over the New European Driving Cycle

Variations in speciated emissions from spark-ignition and compression-ignition motor vehicles in California's south coast air basin.

The U.S. Department of Energy Gasoline/Diesel PM Split Study examined the sources of uncertainties in using an organic compound-based chemical mass balance receptor model to quantify the contributions of spark-ignition (SI) and compression-ignition (CI) engine exhaust to ambient fine particulate matter (PM2.5). This paper presents the chemical composition profiles of SI and CI engine exhaust fr...

The Effects of Ethanol–gasoline Blend on Performance and Exhaust Emission Characteristics of Spark Ignition Engines

The effects of unleaded gasoline and unleaded gasoline–ethanol blends on engine performance and pollutant emissions were investigated experimentally in a single cylinder, four-stroke spark-ignition engine with variable engine speeds (2600–3500 rpm). Four different blends on a volume basis were applied. These are E0 (0% ethanol + 100% unleaded gasoline), E3 (3% ethanol + 97% unleaded gasoline), ...

Control of Exhaust Emissions from Internal Combustion Engined Vehicles

Verification of IVE Model for SAIPA Co. Fleet Emission

To determine the amount of air pollutants, produced by Iranian automakers, and compare it with old and retrofitted vehicles have become one of the important tools of urban management. The present research uses International Vehicle Emission (IVE) modeling software in order to verify SAIPA Co. fleet emissions, based on Euro 4 emission standard (SAIPA Co. recognized as a superior Iranian brand in...
