Toyota 2UZ-FE

the Toyota 2UZ-FE is a 4.7 L (4.663 cc, 284.55 cu in) water-cooled V8, four-cycle, water-cooled, naturally aspirated internal combustion gasoline engine manufactured by Toyota Motor Corporation from 1998 to 2011 The 2UZ-FE engine has 8 cylinders in a V arrangement at a 90 ° rake angle The 2UZ-FE features a cast iron block for increased durability with a five bearing crankshaft and two aluminum cylinder heads with two camshafts (DOHC) and four valves per cylinder (32 total). The Toyota 2UZ-FE engine is equipped with SFI (Sequential Multiport Fuel Injection) system, Direct Ignition System (DIS) ignition system with individual coils on each spark plug, Electronic Spark Advance (ESA) and ETCS-i (Electronic Throttle Control System- smart). The latest engine versions (after 2007) were equipped with a VVTi (variable valve timing) system for the intake camshafts. A cylinder bore of 94.0 mm (3.7 in.) And a piston stroke of 84.0 mm (3.31 in.) Give the 2UZ-FE engine a total of 4,663 cc (284.55 in. cubic) of displacement. The compression ratio rating is 9.6: 1 (before 2007) or 10.0: 1 (after 2007). The Toyota 2UZ-FE engine produced from 230 PS (169 kW; 227 HP) at 4,800 rpm to 288 PS (212 kW; 284 HP) at 5,400 rpm of peak power and from 343 Nm (35 kgm, 253 ft Lb) at 3,400 rpm up to 450 Nm (45.9 kgm, 332 ftlb) at 3,400 rpm of maximum torque depending on the year and model of the vehicle. The engine code breakdown is as follows:

  • two – second generation engine
  • UZ – Engine family
  • F – Economical narrow angle DOHC
  • me – Multi-point fuel injection

Cylinder block: toyota 2uz

The 2UZ-FE engine has a cast iron cylinder block in a V arrangement with a 90 ° bank angle. The firing order for this engine is 1-8-4-3-6-5-7-2. The crankshaft is supported by 5 bearings. These bearings are made of aluminum alloy. The engine is equipped with a fully balanced steel crankshaft with five journals and eight counterweights. The 2UZ-FE engine uses forged and sintered connecting rods. The pistons are made of high temperature resistant aluminum alloy. The piston pins are of the fully floating type. After 2007, the piston shape was changed and oil jets were introduced to cool the pistons. To conserve mass, plastic region tightening bolts are used for the crankshaft bearing caps and connecting rod caps. The Toyota 2UZ – FE engine has two compression and single oil control rings. A 94.0 mm (3.7 in) cylinder bore and 84.0 mm (3.31 in) piston stroke give the 2UZ-FE engine a total of 4,663 cc of displacement. The compression ratio is 9.6: 1 for pre-2007 engines and 10.0: 1 for post-2007 engines.
