Diesel and the Economy

The goal of collaboration is to use significant federal funds to reduce emissions from the most affected most contaminated diesel sources.

Community The goal of collaboration is to greatly improve air quality and public health by targeting the most polluting engine

Diesel and gasoline internal combustion engines are most commonly used in automobiles. Diesel engines have more than 30% fuel efficiency, better fuel economy, and less carbon dioxide emissions. Before purchasing vehicles equipped with diesel engines, remember that they also release more nitrogen oxides (NOx). Nitrogen oxides help smog, acid rain, particulate matter formation and destroy the ozone layer. Good news: Diesel technology is getting cleaner. Interest in cleaning diesel vehicles is increasing, and in theory it is not compromised by performance and pollution. However, the recent Volkswagen scandal on the misconduct of large-scale exhaust gas tests raises questions about the future of clean diesel vehicles. The rigging emission test of 11 million cars means that they may cause nearly 1 million tons of air pollution every year.

Diesel engines emit complex mixtures of air pollutants consisting of gases and solid substances. Visible emissions in diesel exhaust are called particulate matter or PM. In 1998, California identified diesel exhaust particulate matter (PM) as a toxic air pollutant. Because it can cause cancer, premature death and other health problems. Diesel engines can also cause California PM 2.5 (large particulate matter) air quality problems. The most vulnerable is the elderly who may still have children with developing lungs and other serious health problems. According to California's 2005 emissions, about 3,500 people dies early in the diesel PM every year, thousands of people have admitted hospitalizations, asthma attacks and other respiratory symptoms, losing work days. Generally, diesel engine exhaust is the cause of the majority of cancer risks due to outdoor air pollutants known in California. ARB sponsors research related to diesel health

Diesel vehicles usually have better fuel economy and less greenhouse gas emissions than comparable gasoline engines. Their excellent economics are attributed to the high energy per liter of diesel fuel and the inherent efficiency of diesel engines. The density of petroleum diesel is higher than the density of gasoline, but as the gas emissions per heating chamber is higher, the fuel economy of modern diesel engine vehicles increases by 20 to 40%, which is the gas emissions per heating chamber And offset the emissions of diesel vehicles. Ten greenhouse gases are 20% less than similar gasoline cars. The diesel engine of biodiesel engines maintains the advantage of fuel efficiency superior to conventional gasoline engines while significantly reducing emissions compared to petroleum diesel engines and gasoline engines. However, an increase in the compression ratio means an increase in the emission of nitrogen oxide (NOx) from the diesel engine.
