In this article, we will discuss the Diesel-Ethanol Blend. Ethanol has a Cetane number of -8, whereas Diesel has around 46 Cetane numbers all over the world. Here you can find the all details: 

Can a Diesel Engine Run on Ethanol- 

Yes, Diesel engines can run on Ethanol. Ethanol-diesel blends contain up to 15 volumes of percent ethanol and an additive known as an emulsifier. Biodiesel has been shown to reduce emissions and improve fuel efficiency in diesel engines, though its use can also result in decreased engine performance and lifespan compared to diesel fuel. 

Additionally, not all diesel engines are designed to run on biodiesel and may require modifications to do so. There is a reduction in soot and NOx when using an ethanol blend, but a slight increase in unburned HCs. In the United States, a number of organizations set fuel ethanol quality standards and specifications. The U.S. Bureau of Alcohol, Tobacco, and Firearms sets minimum standards for denaturing fuel-grade ethanol. Let’s see the details of the diesel engine and Ethanole. 

Diesel Engine- 

A
diesel engine is an internal combustion engine that uses diesel fuel to ignite
the compressed air-fuel mixture. Diesel
engines do not use spark plugs to ignite the fuel. Diesel
engines are known for their efficiency and durability. They are often used in
heavy-duty vehicles, such as trucks, buses, and construction equipment, as well
as in ships, trains, and power generators. 

Diesel
engines are also more fuel efficient than gasoline engines. This is because
diesel fuel contains more energy per gallon than gasoline, and diesel engines
are designed to extract more of this energy from the fuel.

In conclusion, diesel engines are a
popular choice for many applications due to their efficiency, durability, and
high torque output. Although they have some disadvantages, advances in
technology are helping to make diesel engines cleaner, more efficient, and more
affordable for consumers. 

Ethanol Engine- 

An ethanol engine is an internal combustion engine that runs on ethanol fuel. Ethanol is a bio-based fuel that can be produced from crops such as corn, sugarcane, and wheat. Ethanol blends with the other fuels to operate inside the cylinder. Ethanol engines are similar to gasoline engines, but they have been modified to run on ethanol fuel.

The use of ethanol fuel in engines has been shown to reduce emissions of harmful pollutants such as carbon monoxide and particulate matter and to improve fuel efficiency compared to gasoline engines. The government also forces motor companies to make more vehicles that are friendly to the Ethanole. Ethanol is a Biofuel that is available everywhere.

However, ethanol engines have several disadvantages compared to gasoline engines. It may cause corrosion in the engine and fuel tank because of its water attraction.

Advantages of Bio-diesel cars-  

Bio-diesel cars have many advantages over traditional gasoline cars. However not all diesel engines are not made of ethanol. here are some advantages- 

1. Bio-diesel is environmentally friendly. Bio-diesel is made from vegetable oil, animal fats, sugarcane, and from many other things. 
2. Bio-diesel fuel produces less emission compared to traditional diesel engines. It is a more reliable fuel.  
3. Bio-diesel fuel has a better lubricating property. It can extend the life of the engine and reduce wear and tear. 
4. Bio-diesel can improve engine performance compare to diesel engines. It has better cold weather starting and smoother operation. 

Disadvantages of BIo-diesel cars- 

Bio-diesel car has several disadvantages compared to diesel cars. Here are the disadvantages- 

1. Bio-diesel fuels can be more expensive than a diesel engine, where it is not widely available.
2. Not all diesel engines are designed to run on bio-diesel, and some engines need modifications. 
3. Bio-diesel fuel can have lower fuel energy density compared to diesel fuel.
4. Bio-diesel fuel is more reactive than diesel fuel and can break down more quickly, making it important to store and handle it properly to avoid contamination.
5. The use of bio-diesel fuel has been shown to reduce the lifespan of some diesel engines and increase the frequency of maintenance compared to diesel fuel.

Differences between Bio-diesel cars and diesel cars- 

It is very important for you to judge whatever is right for you. Find the differences below- 

Sl.No	Bio-Diesel	Diesel
01	Bio-diesel is made from renewable sources.	Diesel is made from petroleum.
02	Bio-diesel fuel produces lower emission	Diesel fuel has many pollutant particles.
03	Bio-diesel is not for all engines.	Diesel engines are traditional engines.
04	Bio-diesel has lower energy density.	Diesel engines have much more energy.
05	Bio-diesel fuel can be expensive, where it is not available.	Diesel fuel can be less costly.
06	Bio-diesel is not widely available in all regions.	Diesel fuel is available in all regions.
07	Bio-diesel can reduce the life of an engine.	Diesel doesn’t have such problems.
08	Bio-diesel cars can reduce performance in cold weather.	Diesel engines do not have any problems in cold weather.
