The turbocharged 22RTE had a brief to production run. The engine underwent a significant redesign in to solve timing chain problems. There were few differences between post 22R and 22RE engines other than the 22RE having fuel injection.

The 22R was the successor to the 2. The 20R, 22R and 22RE enjoyed immense popularly with Toyota owners in North America for their workhorse dependability and reasonable power packed in tight four-cylinder blocks. Throughthe 20R and 22R powered the Celicas, which was one of Toyota's premier sellers in the late s to mids.

The engines featured hemispherical, swirl-inducing combustion chambers not unlike the Hemi engine design by Chrysler. They had efficient cross-flow heads and long 3. The 22R had round exhaust ports and the 22RE had keyhole-shaped exhaust ports. The 22RTE, which powered some pickups and 4Runners, derived from the 22RE, but with a different head and block, dished pistons and combustion chambers shaped differently. The 22RTE also featured different oil passages. In addition to the Celica, the 22R powered the Toyota Corona, to Hilux pickup, to pickup and the 4Runner.

The 22RE powered the to Hilux, the to standard pickup and the to 4Runner. However, the Celica entered in the race had a U. The team dropped the 22RE in the Celica, qualified for the race, and then finished third place behind two six-cylinder BMWs. It was the highest finish for any 22RE-powered Toyota.

The carbureted 22R, from todeveloped 72 horsepower and foot-pounds of torque. The to 22R generated 81 horsepower and foot-pounds of torque. The 22RE in produced 78 horsepower and a foot-pound torque rating, and then saw output climb in to 84 horsepower and foot-pounds of torque.

Toyota motorhomes had different horsepower ratings. The turbocharged 22RTE generated horsepower and a whopping foot-pounds of torque. Both the 22R and 22RE had a 9-to-1 compression ratio. Carburetors varied through the production run.

The 22R initially featured a stock single-barrel cfm carb. However, owners could also fit their 22Rs with a single-barrel cfm Weber, dual Webbers with or cfm, or the dual Mikuni 40 PHH or 44 PHH with cfm and cfm respectively.

InToyota swapped the dual-row timing chain used in older 22R engines for a single-row chain with plastic guides. Inthe 22R engine was redesigned, many parts from the newer 22R such as cylinder head, block, pistons, the timing chain, and cover, water and oil pumps are not compatible with those from the older pre engine.

The Toyota 22R has a cast-iron cylinder block with five bearing support system. It has a The cylinder head is made of aluminum alloy which gives it good cooling efficiency. The engine has single overhead camshaft, that is driven by a timing chain and two valves per cylinder 8 valves in total.

You apparently didn't put one of the new cover sheets on your TPS reports. You see, we're putting the coversheets on all TPS reports now before they go out. If you could just go ahead and make sure you do that from now on, that will be great. As such they lack a mechanical carburetor and instead split the function of the carburetor into three parts, namely the Air Flow Meter in the air cleaner box, the throttle body and the fuel injector.

The throttle body controls the air flow into the engine and the fuel injectors supply the proper amount of fuel to each piston depending upon operating conditions. For specific information, be sure to consult the service manual for your model engine. The throttle body Figure 1 contains the throttle valve that it operated by the accelerator pedal in the driver's compartment. The valve serves to regulate the amount or air that gets introduced into the engine.

The fuel injectors spray atomized fuel into the intake of each cylinder in response to an electrical signal from the engine computer ECU. One determining factor among many for the amount of fuel to inject is based upon the position of the throttle valve.

This position is determined by the throttle position sensor TPS. So why test it? Well, assuming you are having an engine-related issue that you think might be due to the TPS see troubleshooting section for common symptomsthen it makes sense to test the one you have first.

The TPS itself is simply a linear variable resistor that when driven by the ECU produces a linear voltage in a volt range, 0 volts being idle and up to 5 volts representing throttle opening angle.

Internally, there is also a switch that detects the idle position. Proper adjustment of the TPS is critical for engine performance, fuel economy, and emissions. Aside from being out of adjustment, the TPS can just plain wear out or break internally.

Periodically, the throttle body should be cleaned or checked for a buildup of sludge that may clog the air bypasses, vacuum ports, or prevent the throttle plate from closing to it's proper position. This should be checked prior to any adjustment of the TPS should a trouble code relating to throttle position appear during a self-diagnostic test. Crankcase vapors are commonly vented into the throttle body for re-introduction into the combustion process by the Exhaust Gas Recirculation, or EGR, valve.

These vapors can leave an oily residue on the back of the throttle pate and allow sludge and dirt to accumulate. The throttle body can easily be cleaned while on the vehicle with a little carburetor cleaner and a cloth.

However, for heavy sludge buildup, it should be completely removed, washed in solvent, and dried thoroughly. When doing this, it is important that the TPS should be removed to prevent contamination a primary cause for failure and the throttle body-to-plenum gasket replaced. The TPS is adjusted by means of rotating it slight with respect to the throttle body itself.

To check the TPS, first unplug the connector from the sensor, then using a thickness gauge between the throttle stop screw and the stop lever, use an ohm meter see Figure 3 to check the various terminal-terminal connections for proper resistance values see Table 1. Obviously, these tests are done with the engine not running. We now offer a quality metric feeler gauge set that allows all the various throttle stop gaps to be set with one or two shims in various combinations.

It has 0.The Toyota R family was a series of inline-four gasoline automobile engines. Designed for longitudinal placement in such vehicles as the Celica and Hilux and in production from throughusage faded out as many of Toyota's mainstream models moved to front-wheel drive.

Overhead cam OHC versions featured a chain-driven camshaft. The 1. The R engine was the Toyota engine used in the Toyota Crownthe first model to be exported to the United States. Production had been gradually transferred from the original Honsha plant to the new Toyota Kamigo plant in Applications: [2]. When introduced it had a 7.

In the 3R was uprated to and the 3R-B version was offered from through with the old 7. The 3R-C was introduced to comply with Californian emissions laws.

The 3R-LPG variant was made for the last five years. The 2. It is a two-valve OHV engine. The 7R-LPG was produced from through Cylinder bore and stroke was It was a major departure for the R family. From to Feb it was known as the 10Rbut along with a removal of the tensioner gear in the interest of quieter operation, it was renamed the 8R-G to reflect the decision that twin-cam engines were henceforth to be identified by a "-G" suffix.

Bore and stroke The cam lobes activated the valves directly via a bucket over shim arrangement.

A total of 2, 9R engines were built. The twin cam 1. The later 8R-G version did not receive a timing chain tensioner in an effort to make it more silent. The 12R-LPGwas produced from through The OHC 1. There was also a 16R-J version for various commercial vehicle applications. The 18R series shared a 2. The 8-valve DOHC 18R-G and its variations were produced from toreplacing the 8R-G and providing a performance engine which took advantage of the entire 2-litre limit of Japan's " small car " class.

Except for the head and related timing components, most parts were shared or interchangeable with the SOHC 18R. Combustion chambers were hemispheric. Inair injection was added to the Japan-market 18R-GR for improved emissions.

This used Solex carburettors. There was also a catalyzed carburetted version, the 18R-GU. German racing team Schnitzer also developed a turbocharged silhouette racing version of the Celica, [14] to take on the Porsche The 2-valve SOHC 2. The 19R was a short-lived experiment by Toyota, and was only offered in Japanese market cars. Aluminum alloy heads were used. The head was changed from a reverse-flow to a cross-flow type with hemispherical combustion chambers and shorter valve rockers.

The timing chain was strengthened. The lower block bearings were strengthened against wear, safeguarding oil pressure, and the stroke was lengthened.
