ecot3
Komatsu has been developing and manufacturing in house both the
construction vehicles and engines: equipment since 1931 and diesel
engines since 1935. Supported by such experience, the ecot3
technology was developed aiming for preservation of the Earth's
environment (Ecology) and the customer's productivity (Economy). What
makes us successful is our strong technological capabilities and power
that integrates them into efficient machinery.

ENVIRONMENT FRIENDLY FEATURES [No.3]
Design features of SAA6D114E-3 engine (2/3)
New combustion technology ICS
(in-cylinder-solution) reduces NOx emission
without using EGR.
Electronic-controlled high pressure fuel injection
system realizes both low NOx emission and high
performance.
The exhaust color density during acceleration is
also reduced.
4-valve (per cylinder) system to
increase cylinder intake air flow.
Injection nozzle arranged at
cylinder center to effectively use
the air contained in cylinder (to
promote fuel-air mixing)
The common rail fuel injection
system assures high-pressure
fuel injection in low-speed range
to increase low-speed torque.
