ASET™ AC (CEGR) Engine
Features and Components
The primary external features that identify the AC
(CEGR) engine include the following items:
앫
Cooled Exhaust Gas Recirculation (CEGR)
system
앫
Variable Turbine Geometry (VTG)
Turbocharger
앫
Modified cooling system with a redesigned
water pump and housing
앫
Front fan and accessory drive arrangement
with dual poly-V belts
앫
Increased capacity oil pan
앫
Relocation of the oil dipstick tube to the oil
pan at the left side of the engine
앫
Enhanced engine electronic control unit
(EECU) with increased capacity to measure
and manage additional sensor inputs
COOLED EXHAUST GAS RECIRCULATION
The ASET™ AC engine with cooled exhaust gas
recirculation (CEGR) incorporates an EGR valve
and cooler along with the necessary piping and
mixer tube (Figure 8). This hardware is controlled
via an engine electronic control unit (EECU) that
regulates the amount of exhaust gas recirculated
into the engine air inlet. Before passing into the
air inlet, the exhaust is cooled from 1200
°
F
(649
°
C) to 350
°
F (178
°
C), enhancing the
effectiveness of the recirculated gases in
reducing the emission of nitrogen oxides (NOx).
