In addition to their widely distributed diesel engines, Komatsu is a major global supplier of road construction and quarry equipment.

Komatsu diesel engines are developed and manufactured at the highest technical and engineering level, allowing the company’s power plants to function reliably across five continents, despite the continents’ severe cold and dangerously high temperatures. Contemporary name-brand motor vehicles are a synergy of technological advances and technical prowess. Because of this, in particular, the engine’s service life is extended, fuel consumption is decreased, and adverse environmental effects are mitigated because the electronic control system quickly processes the data from the sensors to optimize the power plant’s operation by the load at the moment. Komatsu’s technical accomplishments include the HPCR high-performance high-pressure fuel injection system, a combustion chamber of its design, an air intake air cooling system, and many other solutions that make these engines not only cost-effective and environmentally friendly but also highly reliable and able to work for long periods at peak demand.

A few of the motors are created from scratch by Komatsu’s engineering staff. This company collaborates with Cummins on the development of sure of their engine models. Komatsu and Cummins’ collaboration dates back many years. The Cummins NTA-855 was one of the earliest Cummins engines built in large quantities and was used in Komatsu machinery. The two companies continued to work together and eventually merged to become Komatsu Cummins Engine Co., Ltd., with headquarters in Japan. The most popular Komatsu engines are co-developed and manufactured with Cummins, and both are based on diesel engines:

• Komatsu S4D95,
• Komatsu S6D102,
• Komatsu SA6D114,
• Komatsu SA6D170.

Komatsu machinery also has engines from Perkins, Yanmar, and Iveco.

When it comes to powering their machines, Komatsu relies on:

• Both dry and wet sleeve options. To avoid scoring and wear, the inside surface of most sleeves is nitrided.
• Pistons made of aluminum and wrought iron provide long life and dependable performance.
• The primary functions of piston rings are to transmit heat from the piston to the cylinder liner and to contain the compression gas pressure inside the cylinder. They are constructed from a high-strength steel alloy, making them impervious to wear and heat.
• High pressure and high turns may be achieved by rotating a cranked shaft with the help of liners. Although one metal (the primary one) is used in the construction of each liner, additional layers and an outside coating increase the component’s durability and dependability.
