- In order to meet the demands for reduced emissions and improved fuel consumption, a subport-type variable swirl system (Isuzu Variable Electronic Economy Swirl, or IVES) was developed by Isuzu for medium- and heavy-duty direct-injection-type diesel engines. The main characteristics of IVES are:
-
(1)
It is simple in structure and only minor changes to the cylinder head are required.
-
(2)
Modular design is possible for three different swept volume engines due to the use of a common actuator and sensor.
-
(3)
The problem of air flow coefficient drop when swirl is varied has been successfully eliminated.
