D902-K (Displacement 0.898L)

“D902-K (Displacement 0.898L)” is the electronically-controlled diesel engine below 19kW.

D902-K saves users of our current engines from the need to develop new machinery to accommodate changes in dimensions and/or structures of said engines and is capable of complying with the latest emission standards (output of below 19kW) around the world.

Equipped with a one-of-a-kind common rail system developed exclusively for small engines, D902-K comes with a new combustion system, TVCR™. The end result is that it is compact and easy to mount, with clean emissions (the amount of black smoke are reduced to an imperceptible level) and low fuel consumption.

This innovative engine corresponds to various regional emission standards, including China's national smoke regulations Category III, which are the toughest state-wide smoke emission standards there, in addition to EPA Tier 4 (North America), Stage V (Europe), and China IV standards (to be implemented in December 2022).

SUPPRESS BLACK SMOKE
The amount of black smoke is reduced to an imperceptible level at start, acceleration, and a rapid increase in workload, which corresponds to Category III smoke regulations in China.
LOW FUEL CONSUMPTION
D902-K consumes about 5% less fuel than its current conventional model.
DRIVABILITY
  • ・Controlled electronically, D902-K is capable of communicating via CAN*, thus allowing engine speed and torque to be controlled using signals from vehicles.
  • ・Engine operating data, which are essential for telematics service, can be acquired via CAN.
  • ・Due to the torque characteristics that could not be realized by mechanical governor control, it suppresses the decrease in rotation at the time of sudden load and improves drivability and work efficiency.
COMPATIBILITY
D902-K uses the same external dimensions, locations of ports and an engine mount, and PTO (Power Take Off) as its current model, thus facilitating easy model upgrades.
