| Engine: The 2.3 liter inline-4 has been dropped, leaving only the 2.0 liter inline-4. The chassis was made lighter and stiffer, and the 2.0l engine was modified to increase efficiency; overall the new Focus was aimed to meet the fuel efficiency of the Honda Civic. Ford dropped the old 4-cylinder Zetec engines in favor of Mazda's MZR design. Thus, 2005 and present Duratec
4-cylinder engines are Mazdas. This includes the 2.0 L Duratec 20 and 2.3 L Duratec 23. The engine is currently built by Ford in Chihuahua, Mexico, Dearborn, Michigan, Valencia, Spain and Nanjing, China. The 2.0 L (1988 cc) version built in Chihuahua, Mexico. Bore is 87.5 mm and stroke is 83.1 mm. On the Focus, output is 136 hp at 6000 RPM with 136 ft·lbf of torque at 4250 rpm. The Focus sold in the US states of CA, NY, MA, VT and ME comes with the required PZEV emissions
20E version, which produces 130 hp at 6000 RPM with 129 ft·lbf of torque at 4000 rpm. The PZEV is available as an option in border states. The compression ratio for both versions is 10:1. It has an aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses SFI fuel injection, has 4 valves per cylinder and features fracture-split forged powder metal connecting rods, a one-piece cast camshaft, and a cast aluminum or reinforced plastic intake
manifold. It does not have VVT (variable valve timing). The power output is less than the Mazda version which does have VVT. |
