Diesel Injectors

In a normal car that takes gas and not diesel, there is an area in the engine where fuel and air are mixed. This usually takes a long time to happen. In a diesel vehicle, there is no waiting time here. The diesel fuel injector injects the fuel into the cylinder right away.

You’re wondering why this is needed? Well, this is because diesel vehicles create a gas called NOx. This is said to be harmful to the environment.

Diesel manufacturers created diesel exhaust fluid (DEF) to take care of the pollution issues. In this chamber, the diesel exhaust fluid is turning the gas from a harmful gas (nitrogen dioxide and monoxide) to a gas that does not damage the environment (nitrogen and water) before it leaves the exhaust.

Cons of Diesel Exhaust Fuel

The downside of this occurrence is that it can become clogged more often than you’d like it to. This is going to affect the whole performance of the engine if you don’t stay on top of it.

Trucks that have the DEF converter are said to cost a bit more. This is because of the upgrades the truck has to have, including the full indicator which tells you how much DEF you have in your tank.

DEF is a liquid that does not have a high freezing point. This liquid is capable of freezing. Do not fear though, your engine runs hot and this is enough to keep the DEF unfrozen.

You can’t purchase DEF at a gas pump as you can with diesel fuel. You’ll have to head into an auto store, convenience store, or pack some with you.

Pros of Diesel Exhaust Fuel

Any engine that uses diesel is now made to have diesel injectors. If you happen to purchase a really old vehicle it may not have one.

You’re going to see better performance in a DEF vehicle. This is because the engine is now producing a mixture of nitrogen and water. This combination isn’t even going to hurt you. If it was still producing negative chemicals, this creates wear and tear on the engine, too.

The cost to refill this tank is going to be a no-brainer. It is similar to getting gas, but it goes into a certain spot. You won’t want to add this liquid to the wrong area. Every fourth time you need gas, you are probably going to need to top-off your DEF.

This fuel is not expensive at all. This is going to run you $2-$3 depending on the size you purchase

Keep DEF Full

You’ll know about this coming expensive before you purchase the vehicle. This is why you’ll have enough time to make sure you never run out. In these approved DEF vehicles, if you run out, the vehicle is going to notify you in some way–probably with a red warning sign.

When the vehicle is out, the car is going to move into a protective mode and you won’t be able to go more than 5 miles per hour until it is full again. You should keep this liquid on vehicles that need DEF to perform.
