Electronic Control System

Komatsu’s electronic control system processes the signal sent from the comprehensive set of sensors which installed in the different part of the machine at high speed, and optimize machine performance to meet the varying needs of operation. This system reduces environmental impact: cutting emissions of PM (particulate matter) and NOx, enhancing fuel economy and reducing noise. It also offers better performance in severe environmental conditions, including high altitudes and extremely high and low temperatures.

Heavy Duty HPCR System
(High Pressure Common Rail fuel injection)

In this system, a high-pressure pump is used to pump fuel into an accumulator chamber called “common rail” in the common rail system. From there, the fuel is injected in the engine cylinders with optimized injection rate by an ECU (electronic control unit). Conventional mechanical injection systems feed each cylinder with rather crude control of injection volume. the Heavy Duty HPCR optimizes control of multiple injection volumes, multistage injection timing and maximizes combustion in order to achieve both reduced emissions (PM) and high performance (high output, low fuel consumption, low noise).

New Combustion System

The shapes of the combustion chamber has been specially configured on the basis of computer simulations and analysis. Our New Combustion System optimizes combustion timing and ignition – reducing NOx and PM, improving fuel consumption, and cutting noise – all at the same time.

Air to Air Charge Air Cooling System

Komatsu uses a turbocharger to feed the engine cylinders with the larger volume of air necessary to improve combustion efficiency, lower emissions, and enable higher engine power. However, compression generates heat, so we also use a high performance cooling system to cool the compressed air to an optimum temperature. This contributes to reducing NOx and also benefits fuel consumption.

Total Development of Engines and Vehicles

Since Komatsu develops both engines and vehicles, we know how to match one to the other to create equipment package optimized for the conditions which they will have to operate under and the requirements which they have to meet. This capability gives us an edge over companies that just make engine.

Quality and Endurance Testing to Ensure Durability

Construction machinery has to survive high and low temperature, extreme vibration, dust, and high sulfur fuels. So Komatsu carries out the most grueling quality and extended endurance testing to make sure our engines have what it takes.

State-of-the-Art Production Facilities and Quality Control Systems

Our manufacturing plants feature state-of-the art production and the strictest quality control systems. And to guarantee that our customers get the superior quality which they have to come to expect from Komatsu, we manufacture all key parts and components in-house.
