22R The 2-valve SOHC 2.4 L (2366 cc) 22R was produced from 1981 through 1995.
Cylinder bore was 91.9 mm (3.62 in) and stroke was 88.9 mm (3.5 in). 缸徑為91.9毫米（ 3.62的）和中風為88.9毫米（ 3.5 ） 。
Initial output was 97 hp (72 kW) at 4800 rpm and 129 ft·lbf (174 N·m) at 2800 rpm. 最初的產量為97馬力（ 72千瓦）在4800轉和129英尺磅（ 174牛頓米）在2800轉。
By 1990 the 22R was producing 108 hp (81 kW) at 5000 rpm and 138 ft·lbf (187 N·m) at 3400 rpm. 到1990年生產的22R是108馬力（ 81千瓦）在5000轉和138英尺磅（ 187牛頓米）在3400轉。
第一燃料注入 22R娥引擎出現於1983年。
Output of these engines is commonly rated at 105 hp (78 kW) at 4800 rpm and 137 ft·lbf (185 N·m) at 2800 rpm. 這些發動機的輸出通常是額定105馬力（ 78千瓦）在4800轉和137英尺磅（ 185牛頓米）在2800轉。
In 1985, the engine was significantly reworked, output was up to 112 hp (84 kW) at 4600 rpm and 142 ft·lbf (192 N·m) at 3400 rpm. 1985年，發動機明顯返工，輸出高達112馬力（ 84千瓦）在4600轉和一四二英尺磅（ 192牛頓米）在3400轉。 Many parts from the newer 22R-E are not compatible with those from the older pre-1985 engine. 許多地方的新22R - E是不符合這些從老前1985年的引擎。 Non-compatible parts include the cylinder head, block, pistons and many of the associated parts such as the timing chain and cover, and water and oil pumps (although the oil pump internals are the same). 不兼容的部分包括缸蓋，塊，活塞和許多相關的零部件，如鏈和支付時間，以及水和油泵（雖然油泵內部都是一樣的） 。
Toyota swapped the dual row timing chain used in older engines for a single row chain with plastic guides in 1983. 豐田換成雙行時間鏈中使用舊引擎單列鏈塑料指南於1983年。 This system reduced drag on the engine, but was inherently problematic. 該系統減少拖累引擎，但本質上是有問題的。 Every 80,000 to 140,000 miles, the chain stretches to the point that the hydraulic-operated chain tensioner can not take up any more slack. 每80000至一十四點〇 〇 〇萬英里，鏈條延伸到一點，即液壓操作鏈拉緊不能接受任何鬆懈。 When this happens, the timing chain impacts driver's side chain guide, breaking the plastic within a few hundred miles of driving. 在這種情況下，時間鏈影響司機的側鏈指導，打破了塑料在幾百英里的駕駛。 If the engine continues to be operated after the guide breaks, the chain will stretch rapidly (an unfortunate characteristic of single row chains.) The loose chain causes inaccurate ignition timing which usually results in noticeable rough running. 如果發動機繼續進行操作指南休息後，將延伸鏈迅速（一個不幸特點單列鏈。 ）鬆散鏈點火時間不準確的原因，通常的結果明顯粗糙運行。 It may also rub a hole in the soft aluminum timing cover, resulting in engine coolant being forced into the oil sump and ultimately destroying the engine. 它也可能摩擦中的一個漏洞軟鋁時機覆蓋，導致發動機冷卻液被強迫進入油底殼，並最終摧毀了引擎。 In continued operation the chain can jump a tooth on the drive sprocket or break entirely, with either case resulting in engine damage from valve-piston collisions. 在繼續運作鏈可以跳轉牙齒的驅動器上鏈輪或完全中斷，與任何一種情況下造成的損害閥發動機活塞碰撞。
The turbocharged 22R-TE (sold from late 1985 through 1988) produced 135 hp (101 kW) at 4800 rpm and 173 ft·lbf (234 N·m) at 2800 rpm.
However, its weakness is high-end power. 然而，其缺點是高端電源。 Thus, most performance enthusiasts usually prefer the Toyota 18R-G , 2T-G , 4A-GE and 3S-GE 4-cylinder engines, The 22R has a bigger displacement and a strong block, but its comparatively long stroke limits its use in high revving applications.
The engines are extremely well known for their durability, high fuel efficiency and good low to mid range torque. 發動機是極其眾所周知，其耐用性，燃油效率高和良好的低到中期範圍內扭矩。
