Improving your diesel exhaust system

Diesel vehicles are becoming more and more popular these days for a variety of different reasons. One of the more popular reasons is the overall increased efficiency of these types of vehicles.

Diesel trucks and cars have always been more efficient in the fuel department than traditional gasoline engines. They were also a lot rougher running and not nearly as affordable as gasoline engines. Those are the main reasons why they never really caught fire and became the most popular means of powering transportation.

But things are definitely starting to change in the world of diesel engines. With more people purchasing these vehicles then at almost any point in human history, it’s become increasingly more important for diesel owners to understand what there is to know about their diesel exhaust system.

Why are diesel vehicles so much more fuel efficient in the first place?

You have probably heard a whole bunch of different reasons behind why diesel vehicles are so much more efficient than traditional gasoline vehicles. The odds are pretty good that you haven’t heard the real reason before.

People like to talk about all kinds of engineering mumbo-jumbo when they talk about why diesel vehicles are so much more efficient. They never cut to the actual root of the increased efficiency. The fact is that diesel is a higher density fuel which makes it burn at higher temperatures, requiring less fuel to produce an equal amount of power.

There are more BTUs in a gallon of diesel fuel than there is in a gallon of gasoline. A BTU is a British thermal unit. It’s a unit of heat that is used to measure energy.diesel exhaust

Combine that with an intelligently designed diesel exhaust system that increase efficiency even more, and you’re looking at vehicles that are able to blow traditional gasoline vehicles out of the water. When it comes to miles per gallon ratings, diesels will almost always win.

It’s also popular to design a diesel engine with a turbo charger integrated into the exhaust. The turbo is powered by the diesel exhaust. The spinning of the turbo forces air into the engine so that the engine can run at a higher compression ratio. A higher compression ratio will burn fuel more completely and efficiently. The higher compression ratio is another reason that diesels are more fuel efficient.

Improving your already impressive diesel exhaust system is easier than you thought

Another reason that so many people love diesel vehicles is because they are very easy to modify and improve. This is especially true when it comes to your diesel exhaust system.

All diesel exhaust systems are designed to improve airflow out of the power plant. The larger your “pipes” the more air you’ll be able to move. But when you’re talking about increasing the size of your exhaust pipes, you need to be smart about improving your air intake and other aftermarket diesel exhaust components too. If not, you’ll end up with an unbalance engine that breathes better diesel tipon the intake or exhaust side.

Thankfully, there are a lot of “done for you” kits and component collections that allow you to slap a number of parts together right out of the box. Some of these component sets can improve your fuel efficiency by as much as 30% or more without any real effort on your behalf. Usually kits like this will include new fuel injectors and some type of change to the engine computer. This goes along with the free flowing exhaust.

It really doesn’t get any easier than that when you’re looking to improve your diesel exhaust efficiency levels.

Never push the envelope as far as street legalities are concerned

Because of the proliferation of aftermarket components and the desire for pretty much every diesel owner out there to shoot their fuel efficiency ratings through the roof, there are some companies that offer diesel exhaust components that would render your vehicle anything but street legal. This is an issue that you never want to have to deal with.

You always need to stay on the right side of the EPA, or state laws. You need to be 100% certain that your diesel vehicle will always pass necessary inspections. This is why you’ll want to be sure that you are investing in diesel exhaust components that already carry CARB Legal certifications. These will be components that you know are going to improve your efficiency without ever putting you at risk as far as street legal certification is concerned.

CARB is a California based organization that inspects aftermarket parts. They decide if a given part is legal in that state based on how it will affect the exhaust emissions of the vehicle. If the parts you are thinking about installing are CARB approved, they will be 100% OK to use where you live.

At the end of the day, you are always going to have a variety of different options to pick and choose from to improve your diesel engine efficiency. Make sure that you know exactly what you’re getting into before you dive in with both feet.

Understand that making investments in the fuel efficiency of your vehicle is a very smart decision. Increasing the fuel economy of your diesel vehicle now can save you untold fortunes in the future. While diesel fuel is relatively inexpensive now, it could double or triple in price. If this were to happen, the changes you already made to improve your fuel economy will pay back huge dividends.
