The Komatsu Engine

Komatsu Engines are built for power, reliability and durability. Their expertise in building diesel engines for heavy construction machinery is your gain. Komatsu, using experience it accumulated in building engines for construction vehicles has started producing engines for all other types of applications including power generators, industrial machinery and marine vessel products. Whether you are hauling rocks, blasting through piles of dirt, moving rubble or getting cargo places, you can count on a Komatsu engine to get your job done!

History of the Komatsu Brand Engine

Komatsu diesel engines were first sold in America in the 1970s. Komatsu entered the American market with one goal in mind: to be more than just a supplier of construction equipment. They made a commitment to build the most reliable and stable engines that could support every customers’ needs. Komatsu has grown to become the second largest manufacturer of construction equipment, diesel engines and engine parts in North America. Many of these units are produced in manufacturing plants in the United States.

The Famous Komatsu Logo

 

The Komatsu logo, a small pine-tree, has a long and historic past. Komatsu is named after the city Komatsu, located in the Ishikawa Prefecture of the Hokuriku region in Japan. In English,  “Komatsu” translates to “little pine tree.”  According to legend, monk-emperor Kazan planted a field of pine trees in the Hokuriku region during the middle of the Heian period (794-1192).  The area where this pine tree grew became known as “sono no komatsubara” meaning “small pine-field” in English. The name was later shortened to Komatsu.

In the 1990s the Komatsu pine tree logo was changed to what it is today, the letter “T.” The Komatsu logo upholds the ideals of the Komatsu brand: reliability, stability, and strength. It’s unique design of the letter “T” stands for technological innovation.

 

How Komatsu Engines are Used

Although Komatsu engines and Komatsu engine parts can be used for a variety of applications, they are most famous for being the heart and soul of heavy construction equipment. What separates Komatsu engines from their competitors is their innovative use of cast iron pistons and electronically controlled, high-pressure fuel injection systems that limit the emissions from their engines, making them some of the most clean and environmentally friendly diesel engines on the market today. Since 2001, Komatsu has proudly been producing engines that feature such technological advancements such as integrating air-to-air aftercoolers, making sure their engines don’t overheat.
