  E-TVCS VERSION-II. Thus, this engine achieves high combustion efficiency and complies with various regulations of exhaust gas. Based upon the conventional model, Kubota developed a unique governor system and various new mechanisms which reduces exhaust emission, noise and vibration and realize durability and high torque.

• Page 53: Engine Body

  V3300-E2B, V3300-T-E2B, WSM DIESEL ENGINE 2. ENGINE BODY [1] CYLINDER BLOCK This engine employs separate type crankcases — the crankcase 1 (1) with combustion part and the crankcase 2 (2) which supports the crankcase 1 (1) and reduces noise. Since it is a hanger type, you can easily assemble / disassemble it.

• Page 54: Cylinder Head

  It also employs Kubota’s unique combustion chamber with multiple injection grooves. Besides the conventional cross port system, it employs the forced cooling method between valves to eliminate heat distortion, thus enabling durable and reliable configuration.

• Page 59: Fuel System

  DIESEL ENGINE 5. FUEL SYSTEM [1] GOVERNOR The engine employs the separated fuel injection pump in combination with Kubota’s own small multi- function mechanical governor, which enable more dependability. It also employs the torque limiting mechanism to control the maximum peak torque so that it complies with the regulations of exhaust gas.

  V3300-E2B, V3300-T-E2B, WSM DIESEL ENGINE 6. TURBOCHARGER SYSTEM [1] BOOST COMPENSATOR The boost compensator is controlled by the boost pressure of the control mechanism which controls transient smoke caused by oversupply of fuel when the engine starts and accelerates. When the boost pressure is lower than working pressure of the boost actuator (1), it prevents oversupply of fuel to reduce transient smoke.
