Ford Sigma engine
Encyclopedia
The Ford Sigma is a small straight-4
automobile
engine
sold by Ford Motor Company
. First evolution of engines were sold as the "Zetec-SE" (although frequently badged as Zetec-S, not to be confused with the trim level). After the upgrade Ford renamed Sigma to Duratec
. Last upgrade of engine is named Duratec Ti-VCT. The engine was introduced in the mid-1990s and production continues through the present. Like the SHO V6
and SHO V8
, the Sigma was designed with help from Yamaha. Intended for Ford's smaller models, it was intended to replace the older HCS and smaller capacity CVH
units.
The Zetec-SE has no common parts or design with the larger Zetec-E
engines apart from the name. This gives rise to some confusion since it suggests that they are members of the same family, but are in fact, completely different. Zetec-E units are mounted transversely
with the inlet manifold
at the rear, whereas the Zetec-SE units are mounted with the inlet manifold at the front.

in 1.25L (1242cc) capacity, with 1.4 L (1388cc), 1.6 L (1596cc) and 1.7 L (1679cc) derivatives coming later.
The 1679 cc engines uses a heavily modified 1.6 L engine block and features Variable Cam Timing
on the inlet camshaft. This displacement has only been used in Ford Puma
.
Ford upgraded Sigma and renamed it to Duratec
.
The 1596 cc Ti-VCT (Twin independent Variable Camshaft Timing) version includes variable valve timing
, and generates more power and torque over non-VVT counterparts. Latest versions comply the EU5 emission level.
versions of Zetec-SE engines are sold by Ford Power Products under the name ZSG Range.
1.4/1.6 L Sigma
These engines in the First generation Focus produced 75 and 100 bhp respectively, but for MkII Focus the 1.4 variant was slightly modified and produced 80 bhp. Both engines have belt driven camshafts and Electronic Fuel Injection systems. They weight 90 kilograms. http://www.ctm.it/pdf/Powertrain%20Product%20Guide%202007.pdf

The 1.6 Ti-VCT is introduced in 2004, it which features Variable Cam Timing; this 115 bhp version is used in MkII Focus.
A new 105/125 bhp EU5 version is used in the MkIII Focus, also a 1.6 L 120 hp version is used in Ford Fiesta Zetec-S.

Introduction and Innovations
When the Zetec-SE first arrived in 1995 it included many firsts, such as a plastic inlet manifold, a "ladder" style main bearing and crankcase assembly, and big-end bearing caps which are forged in one piece and subsequently split. It also incorporates powder metal connecting rods, which were quite exotic and notable at the time. The engine first appeared in the Mk4 Ford FiestaFord Fiesta

Current Use
Today Sigma engine is used by Focus, Fiesta, C-Max and Mondeo.1.4/1.6 L Sigma
These engines in the First generation Focus produced 75 and 100 bhp respectively, but for MkII Focus the 1.4 variant was slightly modified and produced 80 bhp. Both engines have belt driven camshafts and Electronic Fuel Injection systems. They weight 90 kilograms. http://www.ctm.it/pdf/Powertrain%20Product%20Guide%202007.pdf

The 1.6 Ti-VCT is introduced in 2004, it which features Variable Cam Timing; this 115 bhp version is used in MkII Focus.
A new 105/125 bhp EU5 version is used in the MkIII Focus, also a 1.6 L 120 hp version is used in Ford Fiesta Zetec-S.
Sigma uses the Ford IB5 5-speed transmission.
