Diesel Bronco Engine Swap - 4 Tips Powerful Advantages and FAQs

Advantages of Diesel Engine over Gasoline Engine:

If you’re still on the fence about swapping your Bronco’s engine for a diesel one in your Bronco restoration, let us give you some compelling reasons to do so. Diesel engines have several advantages over gasoline engines, including:

Better fuel efficiency:

Diesel engines typically get 25-30% more miles per gallon than gas engines, which means longer driving range, fewer fill-ups, and lower fuel costs in the long run.

More torque:

Diesel engines produce more low-end torque than gas engines, which means better acceleration, towing, and off-road performance.

Longer lifespan:

Diesel engines are typically built sturdier and can last up to twice as long as gas engines if well-maintained.

Less maintenance: 

Diesel engines have fewer parts, no spark plugs, and no need for ignition timing or tune-ups, which means lower maintenance costs and hassle-free operation.

Resale value: 

Many people prefer diesel vehicles due to their fuel efficiency, longevity, and towing power, which means that a diesel Bronco could retain its value better than a gas one.

Diesel Bronco Engine Swap Tips:

Now that we’ve convinced you that diesel engines are worth it, how do you go about swapping your gas engine for a diesel engine? Here are some tips that we’ve learned from our experience at Krawlers Edge:

Get professional help: 

Engine swaps can be complex and require mechanical expertise and specialized tools. Don’t try to DIY this unless you have experience and knowledge. At Krawlers Edge, we have a team of diesel engine experts who can install your new diesel engine on your brand-new chassis from Kincer Chassis.

Optimize other components: 

Swapping your engine also requires upgrading other components, such as the fuel system, exhaust, and cooling system. Make sure that these components are compatible with your new engine and work together smoothly to avoid problems down the road. We can help you do that by providing guidance and offering the best components to help accelerate your swap!

Test and tune: 

Once your engine swap is complete, it’s time to take your Bronco for a test drive. You can learn a lot from a test drive! From there you can tune the engine and components to get the optimal performance and fuel efficiency.

Important Facts about Diesel Engines:

Diesel engines have a rich history and many fascinating features that are worth knowing. Here are some key facts about diesel engines that you may find interesting:

  • The diesel engine was invented by German engineer Rudolf Diesel in 1892 and was first demonstrated in 1897. The first gasoline engine was invented by French engineer Étienne Lenoir in 1860.
  • Diesel engines operate on the principle of self-ignition through compression, while gasoline engines use spark ignition.
  • Diesel engines have higher compression ratios than gas engines, which means they can compress more air and fuel into a smaller space, resulting in more power and efficiency.
  • Diesel fuel is more energy-dense and has a higher cetane rating than gasoline, which means it can ignite more easily and burn more efficiently.
  • Diesel engines produce less carbon monoxide, unburned hydrocarbons, and greenhouse gases than gas engines, but they produce more nitrogen oxides and particulate matter, which can be harmful to health and the environment if not controlled.
  • Diesel engines are used in various applications, such as trucks, buses, trains, ships, generators, construction equipment, and some passenger cars.

FAQs about Diesel Engines:

We know that you may have more questions about diesel engines and their swaps, so here are some frequently asked questions and their answers:

How many miles can you put on a diesel engine? 

Diesel engines can last up to 500,000 miles or more if well-maintained and operated under normal conditions.

Why was the diesel engine created? 

Rudolf Diesel invented the diesel engine to provide a more efficient and cost-effective alternative to steam engines that were widely used in his time.

Why is diesel fuel more expensive? 

Diesel fuel is typically more expensive than gasoline due to several factors, such as higher refining costs, higher taxes, limited supply, and higher demand from commercial vehicles.

What makes a diesel engine get better MPG than a gas engine? 

The main reasons for diesel engines’ better fuel efficiency than gas engines are higher compression ratio, longer combustion duration, leaner fuel-air mixture, and higher energy density of diesel fuel.
