7. EXHAUST GAS RECIRCULATION (EGR) SYSTEM

[1] GENERAL

In order to meet with the strict emission regulations, Kubota has adopted the EGR on the V3800DI-T-E3. The

nitrogen oxide (NOx) which is a hazardous component in exhaust gas is generated by oxidation of nitrogen in the air,
due to rise of the combustion temperature in cylinders. The EGR is a system in which the exhaust gas with lean oxygen
is cooled and returned to cylinders again in order to lower the combustion temperature. As a result, NOx can be
decreased.

(1) External / Mechanical EGR

External / Mechanical EGR consists of water cooled EGR cooler, mechanical EGR valve, reed valve and thermo

valve.

When the coolant temperature is getting higher, thermo valve is open and the boost pressure of intake manifold

gets to reach the diaphragm of mechanical EGR valve.

If the coolant temperature is high, but the boost pressure is low, the EGR valve does not open. If coolant

temperature is high, boost pressure is also high, EGR valve is open and cooled EGR gas through the water cooled
EGR cooler flows into the intake manifold. And the reed valve between EGR valve and intake manifold prevents the
fresh air flowing into EGR system.
