    Nonroad Emission Standards continue to change. The timing or applicable date of the specific Nonroad Emission regulations depends on the engine output classification. Over the past several years, KUBOTA has been supplying diesel engines that comply with regulations in the respective countries affected by Nonroad Emission regulations. For KUBOTA Engines, E4B will be the designation that identifies engine models affected by the next emission phase (See the table below).

  • Page 309 TRANSMISSION L3560, L4060, L4760, L5060, L5460, L6060, WSM (Continued) Since loads are applied on the motor shaft, the pressure between "A" and "C" is increased. With the pressure between "A" and "C" increased, the pump receives more resistance, thereby decreasing the engine speed.

  • Page 311 TRANSMISSION L3560, L4060, L4760, L5060, L5460, L6060, WSM (Continued) With loads applied on the motor shaft, the pressure between "A" and "C" is increased. With the pressure between "A" and "C" increased, the pump receives more resistance, thereby decreasing the engine speed. Since the engine stall prevention function starts to operate first, the ECU controls the proportional control valve according to signals from the engine speed sensor and accelerator opening sensor so that the engine torque and loads on the HST should keep well-balanced relation.
