Updated version introduced in 2002, with lighter cast-iron
cylinder block and camshaft
driven by toothed belt
. Features EGR
valve and TwinPort
variable intake geometry - twin intake ports with a choke closing one of the ports at low RPM, providing strong air swirl pattern for higher torque levels and better fuel economy. The drive belt for the camshafts is wider and stronger than before, and water pump is not driven by it anymore which improves reliability. Turbocharged

Ecotec DCVCP engines are used in:
D-TEC was an older variant of Family 1 SOHC
engine licensed by Daewoo Motors
for their range of Opel
-derived cars such as Daewoo Espero
and Daewoo Nexia
. These engines are built exclusively at Bupyeong engine plant. They feature valvetrain driven by toothed belt
, in a DOHC
configuration for most versions, and aluminum cylinder head
Updated version of D-TEC. Most models feature Euro III
-compliancy, and 1.4 L and 1.6 L (1598cc) DOHC
versions employ variable intake
Higher-displacement versions of D-TEC and E-TEC II are indeed Family II engines built by Holden.
