Cars and Global Warming: 5 Ways Diesel Engines Are Better for the Environment

By    |   Wednesday, 18 Mar 2015 10:09 AM

Transportation industries continue to take steps that reduce greenhouse gas emissions that contribute to global warming. The oil industry has made significant improvement in refining diesel fuel for cars and trucks.

According to the Diesel Technology Forum, ultra-low sulfur diesel fuel, more efficient engines and effective emissions control technologies have led to the development of clean diesel fuel. Diesel vehicle black carbon emissions are 99 percent lower than in cars manufactured before 2004.

Here are five ways diesel engines are better for the environment:

1. Refining crude into diesel fuel is simpler and cheaper than gasoline. The regulations and restrictions on refining gasoline in the U.S. make it more expensive to produce. By increasing the use of diesel fuel, it offsets the need for more gasoline. This can reduce the impact of greenhouse gases emitted in refining gasoline.

2. Diesel engines can easily use bio-fuels to produce cost-effective vehicles that run more efficiently. Diesel engines don't use spark plugs. They start by a compression ignition system instead of a fuel-injection system. According to WyoTech, the difference can increase the efficiency of diesels over conventional engines by as much as 30 percent. Bio-fuels work without significant modification to diesel engines, unlike the work needed for gas engines. As bio-fuel becomes more available, diesel engines can make an easy conversion with simple modifications.

3. Diesel fuel is more cost effective, producing more energy per volume and giving motorists higher mileage per gallon than gasoline, according to Diesel Service and Supply. This offsets the cost at the pump where diesel is a little more expensive than gasoline. Gas engines burn fuel at higher temperatures than diesel engines, so they have a shorter period of use, which adds waste to the environment.

4. The compression and air to fuel ratios of a diesel engine produce fewer emissions, providing some of the lowest emissions of any oil-based fluids, according to CarsDirect. The direct-injection gasoline engines have an emission rate 10 times greater than modern diesel engines, according to a German TUEV Nord report.

5. Diesel fuel produces minimal amounts of carbon monoxide, making it safer than other fuels for workers while producing fewer greenhouse gases to thwart global warming effects, according to WyoTech. Generators that use diesel fuel are cleaner and safer to use in small spaces, such as mines and other work environments.
