What engine does the Ford Focus use?

[SanMarley]

The Focus is equipped with a 1.6L Ti-VCT engine. More engine details are as follows: 1. This engine is a DOHC inline-four cylinder. Displacement ranges from 1.25L to 1.7L. This engine series are all-aluminum engines (both cylinder block and head are aluminum), with the 1.6L Zetec weighing 81KG net and the 1.6L Duratec weighing 90KG net. 2. The Ford Sigma series engines are small-displacement inline-four gasoline engines. Initially named "Zetec-SE", after upgrades Ford renamed Sigma as "Duratec". The final upgrade renamed it as "Duratec Ti-VCT". This engine originated in the mid-90s (around 1995) and remains in use today. Like the SHOV6 and SHOV8 (large-displacement engines used in Ford pickup trucks and SUVs), Sigma was co-developed with Yamaha. It currently serves in Ford's small-displacement vehicles, replacing the original Kent and CVH engines. 3. The Zetec-SE engine has no relation to Ford's 2.0L Zetec-E in terms of components and design, despite the similar names which might lead us to confuse them as being from the same family. The Zetec-E is a transverse-mounted engine with rear intake manifold, while Zetec-SE has a front intake manifold.
