FEATURES and BENEFITS
Suppress black smoke
The D902-EF81 engine is capable of complying with the
latest emission standards (output of below 19kW) around the
world, including the most stringent of China’s national smoke
regulations, Category III. The amount of black smoke is reduced
to an imperceptible level at start, acceleration, and a rapid
increase in workload.
Improvement
in drivability and serviceability
The D902-K-E4 engine is capable of communicating via CAN,
thus allowing engine speed and torque to be controlled using
signals from vehicles. Due to superior torque characteristics,
lower rotation due to a rapid increase in workload is
suppressed, enhancing drivability and work efficiency.
Low fuel consumption
Fuel efficiency improved by about 5% compared to conventional
model.
Compatibility
The D902-K-E4 engine uses the same external dimensions,
locations of ports and an engine mount, and PTO as its current
model, thus facilitating easy model upgrades.
