Urea or other solid NO x -reducing reagent is employed in a selective catalytic reduction process on emissions from diesel and lean-burn gasoline engines. The solid reagent is fed to a gas generator that produces a reactant gas by heating. In one embodiment the reactant gas is maintained at...
Particulate matter emissions from diesel engines are considerably higher (six to ten times) than from gasoline engines. Diesel particle emissions can be divided into three main components: soot, soluble organic fraction (SOF), and inorganic fraction (IF). More than 50 % of the total PM emissions...
The electricity separates the hydrogen and oxygen from water. The hydrogen is then mixed with CO₂ to produce a liquid e-fuel, which can be produced using many renewable energy sources, such as solar and wind power. E-fuels follow the chemical structure of gasoline, making it possible for...
Experimental Analysis of Consumption and Exhaust Emissions of Gasoline and LPG in Car Engines Under Cold Climatic Conditions. Due to the increasing population, fuel consumption per person is rapidly increasing. Since petroleum reserves are decreasing, the petroleum costs are incre... Arslan,O.,Kose,...
Euro 6 GDI engines < 1.4ℓ delivered ~ 17% CO2 reduction compared to Port Fuel Injection (PFI). Gasoline vehicles delivered an 86–96% reduction in NOx emissions compared to diesel cars. The average urban NOx emission from Euro 6 diesel vehicles 0.44 (sd. 0.44) g km− 1 was 11 ...
The effects of ethanol–unleaded gasoline blends on engine performance and exhaust emissions in a spark-ignition engine Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol is known as the most suited renewable, bio-based and ... Mustafa Koc,Y...
Reduction for Gasoline Engines To reduce CO 2 emissions from cars, it is necessary to improve their fuel economy. This means extracting the kinetic energy from the combustion energy Hitachi Review Vol. 57 (2008), No. 5 185 supplied to the car without any waste. The energy flow ...
Two 1988 model year Ford F700 Series trucks equipped with 7.0 L gasoline engines and two 1986 model year GMC trucks equipped with DDC 8.2 L diesel engines were tested on a heavy-duty chassis dynamometer in a baseline condition and again after conversion to natural gas. The vehicles were ...
