2004.5 Spectra Technology
INTRODUCTION
Powertrain
The new Kia Spectra is equipped with a Beta 2.0 liter
4 cylinder gasoline powered engine. Beta is a Kia
engine family name. The horsepower, compression
ratio, bore and stroke were increased from the
previous Spectra 1.8L engine. The new cylinder head
features a continuously variable valve timing (CVVT)
system that improves performance and emissions.
A new 5-speed with overdrive, hydraulically actuated
clutch, M5BF2 manual transaxle is standard equipment
on the new Spectra. The manual transaxle uses a
hydraulically-activated clutch. A four speed with
overdrive, F4A42 automatic transaxle is available as an
optional feature on all Spectra models and is similar to
the one used in the Optima.
PURPOSE
The new Spectra has a more powerful 2.0L Beta
engine than previous Spectra vehicles. This engine
has a CVVT system designed to burn cleaner and meet
higher emission standards than previous models. The
CVVT system improves engine performance by varying
when the intake valves open and close.
The standard manual transaxle is a 5-speed overdrive unit.
The optional four speed electronic automatic transaxle
is PCM controlled based upon various vehicle inputs
and driver selected position shifter. Overdrive, or 4th
speed operation is automatic when in "D" range; no
driver "O/D" ON/OFF selection is available. The A/T
self-diagnostic is continuously running during key ON.
Depending upon the parameters of the fault found, the
MIL will illuminate and the A/T could go into 3rd gear
fail-safe mode.
