KIA has completed the development of the future DOHC 16 valve spark ignition engine designated the T-series. An all new design was devised for the T-series engine which is being produced on an entirely new plant. This engine has many positive features such as low emission level, good combustion stability, low noise and vibration.
The basic construction of the T-series engine is characterized by 4 cylinder belt-driven DOHC engine, state-of-the-art combustion chambers with tumbling intake ports and a valve angle of 45, deep skirt cylinder block, laminated metal cylinder head gasket, aluminum structural oil pan, and a six ribbed serpentine belt driven accessory system.
Thorough durability testing was carried out on all production parts for the first engine of the T-series; called the T8D engine, of 1.8 litre displacement. Mass production of the T8D engine, installed in the new KIA CREDOS, began in July 1995.
