Methane Emissions from Vehicles

Environmental Science & Technology, 2004
Methane (CH4) is an important greenhouse gas emitted by vehicles. We report results of a laboratory study of methane emissions using a standard driving cycle for 30 different cars and trucks (1995-1999 model years) from four different manufacturers. We recommend the use of an average emission factor for the U.S.

Motor Vehicle Emissions Variability

Journal of the Air & Waste Management Association, 1996
Test-to-test variability has been observed by many current testing methods, including the Federal Test Procedure, the IM240 dynamometer test, the idle test common to many Inspection and Maintenance programs, and on-road remote sensing. The variability is attributable to the vehicle, not to the testing procedure.

Emission factors and emission inventory of diesel vehicles in Nepal

Science of The Total Environment, 2022
A comprehensive emission inventory of the transport sector through fuel-based emission factors (EFs) was developed for the first time in Nepal. This study estimates air pollutants emission from diesel vehicles between the years 1989 and 2018 based on national statistical data, average vehicle kilometers travelled, fuel mileage, and measurement-based ...

Gasolines for Low-Emission Vehicles

SAE Technical Paper Series, 1973
<div class="htmlview paragraph">International concern over air quality and the recognition that the internal combustion engine-powered passenger car is a contributor of atmospheric pollutants has imposed restrictive design criteria upon both the automobile manufacturer and the petroleum refiner.

Zero-Emission Vehicles

2021
Indeed, massive development of transportation sectors accelerating the consumption of fossil fuel has caused nearly 30% of climate change. Necessarily, renewable energy technology needs to be utilized in the transportation sector globally which should be clean in order to develop zero-emission vehicles.

Zero Emission Vehicles

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">Recharging electric vehicles with photovoltaics (PV) results in a truer “zero-emission” vehicle. Other papers have discussed the complex issue of distributed tailpipe emissions versus displaced emissions from centralized generating stations.

R-134a Emissions from Vehicles

Environmental Science & Technology, 2001
We report the first study of R-134a (also known as HFC-134a and CF3CFH2) refrigerant leakage from air conditioning (AC) systems of modern vehicles. Twenty-eight light duty vehicles from five manufacturers (Ford, Toyota, Daimler Chrysler, General Motors, and Honda) were tested according to the USEPA (Federal) extended diurnal test procedure using the ...

Emissions and fuel economy for a hybrid vehicle

Fuel, 2014
Conventional vehicles play a big role in city transportation all over the world. These vehicles run on energy obtained from fossils fuels such as petroleum oils that pollute environment with the gases that are emitted after burning. In addition, the cost of this fuel type will increase because of decreasing reserves; therefore, these petroleum oils ...
