The Differences Between Cummins and Caterpillar Diesel Engines

 

 

If you have done any reading online, you likely have come across mixed reports about Cummins and Caterpillar Diesel Engines.

This can be very confusing, especially if you are seeking the information because you are weighing out whether or not to buy one.

The truth is, that there are positive and negative reports on anything that you can buy in today's marketplace.

But let's look at the facts...

Both Cummins and Caterpillar have established brands with huge customer bases and die-hard fans that swear by them.

That being said, it's probably safe to assume that most of the negative reviews that you've read online could have been avoided somewhere down the line.

We've outlined some of the benefits of each brand so you will be able to make an educated decision when choosing your engine.

The Differences Between Cummins and Caterpillar Diesel Engines

Now, we will show you the differences between Cummins and Caterpillar diesel engines, as well as links to proof of how we came up with our results.

Yearly Sales Comparison

First, let's look at how the yearly sales and revenues of each company are doing.

According to Bob Ciura in this report, Cummins outperforms Caterpillar in sales and is the leading manufacturer of engines and other automotive components.

In the same report, however, Jason Paul states that either company is a great one to invest in, once everything is taken into account.

Cummins is doing great in 2018, and expecting to do even better in 2019 according to this report on the Motley Fool.

Caterpillar on the other hand, despite their stock falling 27% between 2011 and 2015, is expecting a very good year in 2018 according to Analyst Steven Fisher in this article by Bret Kenwell on TheStreet.com.

Cummins Benefits

Cummins diesel engines have been known to utilize some of the best engineering fundamentals in the diesel engine building business.

As a company, Cummins is the most aggressive in the industry for their innovations and uniqueness.

Cummins had a record number of 287 patents in 2017, which shows you how busy they stay to keep their industry dominance.

In the same press release, they mentioned that Cummins has come out with over 200 patents every year since 2014. So, their aggressive pursuit of industry greatness is nothing new.

Cummins engines can be found all over the Earth, on land and on water. Some of the places you will find Cummins engines are:

  • Pick-up trucks
  • 18 wheelers
  • Berry pickers
  • 360-ton mining haul trucks
  • Commercial and Marine water vessels
  • And more

Cummins started out as an aggressive industry leader, basically dominating their market from the onset of their emerging.

They quickly became the industry's dominant big-bore engine, and they have held this rank for the past three decades.

Cummins Diesel Engine Benefits

Cummins is constantly evolving, refining, and making leaps. Just about every critical component of their engines have been modified, upgraded and/or improved over time.

Their 2017 X15 engine, for instance, is said to deliver the highest performance and the most trusted dependability in the industry. Hands down!

The X15 also delivers superior fuel economy over other engines in its class.

Here are some other benefits of the X15 Series from Cummins:

  • Highest Compression Ratio
  • Unmatched Fuel Efficiency
  • Unmatched Responsiveness
  • Over-the-Air Calibration Capability
  • Single Module Aftertreatment System
  • Most Powerful Engine Brake in the Industry
  • Up to 1850 lb-ft (2508 Nom) of Torque (Starting at 1000 rpm.)
  • Extended Service Intervals for Maximum Uptime.

That's just the Cummins X15 Efficiency Series. Now, the X15 Performance Series has even more power, with up to 605 hp and 2050 lb-ft peak torque.

The X15 engines were rigorously tested, pushed for over 8 million test miles before it was even launched.

Cummins takes their name, and their word very seriously. They believe that the Cummins name should always deliver what they promise.

That's why every Cummins engine is backed up by the Cummins service and support, better known as the largest, most capable support network in North America.

Caterpillar Diesel Engine Benefits

Caterpillar's leadership resonates through industries and technologies that most people would never guess they were involved with.

Caterpillar is active with advancements concerning their own products, and the environment. They are a leader in innovations ranging from alternative energy sources to full fleet automation and even space stations.

CAT products have been highly regarded and implemented since they first started out in the business.

They have been a world leader in multiple industries for over 90 years now.

CAT has a huge footprint in construction and mining equipment, diesel and natural gas engines, and much, much more.

Much like the Cummins engines, you will find Caterpillar diesel engines all over the world are in all types of equipment. Some of the places you can find Caterpillar engines is:

  • Articulated Trucks
  • Backhoe Loaders
  • Dozers,
  • Forest Machines
  • Motor Graders
  • Off-Highway Trucks
  • On-Highway trucks
  • And more

The core components of Caterpillar diesel engines over the years have never changed. They have only been added to.

To keep up with strict emissions tests and the evolving diesel industry, Caterpillar has integrated new components, fuel systems, electronics, after treatment designs, and more.

Here are some of the benefits of going with a Caterpillar diesel CT13 engine:

  • Reliable Power - 365-430 hp @ 1700 RPM (Max hp 550.0)
  • 17:1 Compression Ratio
  • 4 Cycle Inline 6 Cylinder
  • Great Mileage
  • Mechanical systems are Simpler on a Caterpillar Diesel
  • The Cylinders Do Not Get Wet

There are a ton more benefits of buying a Caterpillar diesel engine, we just simply could not list them all in this article.

If you want to see a whole list of specs on each engine that CAT carries, check out an equipment list on the Caterpillar website.

Caterpillar offers excellent service and support, and a full lineup of on-highway trucks.

Final Thoughts

As much as die-hard fans of either brand say that one is better than the other, after looking at the evidence, we would have to disagree.

The only substantial differences between Caterpillar and Cummins engines that we are able to pinpoint, weren't that big of a deal.

Caterpillar and Cummins are both amazing brands that care a lot about their customers, and are constantly working hard to achieve greatness in their product lines.

The only real difference that we can find between Caterpillar and Cummins engines, was that Cummins engines have extended service intervals, meaning you can wait longer to have the vehicle maintenanced.

But then they offset this by working harder to make sure that their engines can last the extra time.

We hope this review has helped you get to know some of the world's most amazing brands of diesel engines!.

Don't forget that we've got Celect ECM's and ISB ECM's available for many Cummins engines that are pre-programmed for plug-and-play installation.
