Toyota 22R-E Specifications
The Toyota 22R-E is a 2.4 L (2,366 cc, 144.38 cubic inches) straight-four 4-stroke naturally aspirated gasoline engine from Toyota R-family. The engine was manufactured by Toyota Motor Corporation since 1983 to 1995. The engine features a cast-iron block and aluminum cylinder head with the single overhead camshaft (SOHC) and two valves per cylinder (8 in total). Compression ratio rating is 9.0:1. Cylinder bore and piston stroke are 92.0 mm (3.62 in) and 89.0 mm (3.5 in). The Toyota 22R-E engine has an electronic fuel injection (EFI) system and ignition system with a mechanical distributor. In 1985, the 22R engine was redesigned, many parts from the newer 22R-E (such as cylinder head, block, pistons, the timing chain, and cover, water and oil pumps) are not compatible with those from the older pre-1985 engine. The 22R-E engine can output from 106 PS (78 kW; 105 HP) at 4,800 rpm to 114 PS (84 kW; 113 HP) at 4,800 rpm of maximum power and from 185 Nm (18.9 kgm, 136 ft-lb) at 2,800 rpm to 190 Nm (19.4 kgm, 140 ft-lb) at 3,600 rpm of peak torque. Engine code identification: 22 – 22 generation engine, R – Engine family, E – Multi-Point Fuel Injection.
