Power to spare
A new OHC 4-valve diesel engine and new structure power train
were developed for the ZAXIS-3.
Development Concept of New Engine
OHC* 4-Valve Engine
The new OHC 4-valve diesel engine is developed and built to comply with the rigorous Emission Regulations enforced in 2007 in U.S and EU. This new engine contributes to environmental preservation. At the same time it realizes high durability and low fuel consumption by adopting the latest advanced engine technology.
Common Rail Type Fuel Injection System
Electronic control common rail type fuel injection system drives an integrated fuel pump at an ultrahigh pressure to distribute fuel to each injector per cylinder through a common rail. This enables optimum combustion to generate large horsepower, and reduce PM* (diesel plume) and fuel consumption.
Cooled EGR* System
The cooled EGR system lets part of exhaust gasses mix with intake air for re-combustion to reduce oxygen concentration in the air in the combustion chamber. This design lowers combustion temperature in the cylinder, reducing fuel consumption and NOx while yielding more horsepower.
*Exhaust Gas Recirculation
Excellent Driving Ability, Less Fuel Consumption
Improved Driving Ability
The merits of the new OHC 4-valve engine and new power train, this unit features an increased driving ability in comparison to the conventional ZAXIS-1.
-Maximum travel speed is improved by 17 %
-Acceleration performance is improved by 15 %
Improved Fuel Consumption
The unit features a HIOS II system, which takes advantage of the most sophisticated hydraulic technology, efficiently maximizing the full performance potential of the newly developed engine. It efficiently controls the engine output and hydraulic output which results in lower fuel consumption.
-Fuel consumption when driving on an incline is decreased by 29 %*
*It is one example, this varies depending on the road conditions.
Superior Travel Stability and Drivability
Wider Oscillation Angle
The oscillation angle has been increased by 16 % over the conventional model, ZAXIS-1. Improved surface-holding performance on rough roads results in more stable driving.
Newly Developed Tires for More Comfortable Stability and Drivability
These new tires which were developed in cooperation with Bridgestone features an improved tread pattern and cross section form. This provides lower vibration and lower noise in driving, and even results in improved stability of the unit during operation.
