Motors are the main reason for the pride of Toyota car owners. If you pay attention to modern engine building, you can see that all manufacturers tend to make unreliable turbocharged engines with small volumes. This is done to comply with new environmental regulations.
Toyota took a different path, deciding to continue to produce reliable aspirated with large volumes.
Their environmental standard is achieved through a number of improvements to the gas distribution system, the presence of additional nozzles in the intake manifold, as well as dual-mode operation.
Two-liter unit 6AR-FSE
Over the years, time-tested 1AZ-FE engines were installed on all generations of Camry, which were only being finalized, but the overall design was the same. They were incredibly reliable: their resource reached 500 thousand kilometers. For the model, they were altered thoroughly.
The engine, having the same volume, has become 13 percent more economical and 17 percent faster. The upgraded version accelerates the car by as much as two seconds faster than its predecessors. Such high manufacturability has affected the resource, which has become smaller. This does not mean that the engine has become unreliable, just now its resource is 350 thousand kilometers, which is very good compared to modern engines that can work half as much without breakdowns.
A huge advantage of the 6AR-FSE is the timing chain drive, which is able to work without problems for 200 thousand kilometers.
Combined injection system
The new engine at idle and while driving operates in two different modes. This reduces CO2 emissions and saves fuel. At idle, the unit operates according to the Atkinson cycle, the essence of which is a lower compression ratio and a lower fuel supply. As soon as the drive is applied to the motor, it switches to normal operation.
In normal mode, the car runs with a high compression ratio, almost the same as that of sports units. Mazda has a similar technology called Skyactive. But if Mazda's high-tech engine is designed for 98th gasoline, then Toyota's is imprisoned for 92nd.
This is the most popular Camry engine and most Camrys come with it.
The main characteristics of the motor are shown in the table below.
2.5 liter 2 AR-FE
The 2.5 liter Toyota Camry engine was designed in 2012. This is the best option in terms of dynamics and consumption. If the new 6AR-FSE's 2.0-litre is only enough to comfortably ride around town, the 2.5-litre can allow aggressive driving. Like all Toyota vehicles, this engine is reliable. Despite the large volume, Camry 25 has only 4 in-line cylinders. Such a unit is the most reliable among the line and is able to drive 500 thousand kilometers without major repairs.
An important technical solution is the presence of cast-iron liners in an aluminum cylinder block.
As a result, the 2 AR-FE is as durable as cast iron, but made of aluminium. Like a two-liter counterpart, it has a durable timing chain.
The big disadvantage of 2 AR-FE is that it is not repairable. This is even stated in the description for the Toyota Camry 2.5 engine. Of the minor disadvantages, one can name the flow of the pump and the knock of the shafts of the VVT-i system. This problem does not affect the resource in any way, it only worsens the sound, but it should be understood that if the spare part makes a characteristic sound, then it will soon become unusable.
The main specifications for the Camry 2.5 engine are given below.
Conclusion
Many are faced with a choice: which engine is better to choose. If you buy a car for up to ten years, then will save fuel. Otherwise, 2.5 is ideal. All the units listed above are very reliable, but the best is for the XV50 2.5 AT with 181 hp. This engine gives good dynamics and a high resource. The most popular 2-liter is also good, but has a more complex design and a slightly lower margin of safety. The two-liter 6AR-FSE, designed in 2012, is the most common, not because it is the best, but because it is available on most Camry trim levels.

Reliability, problems and engine repair Toyota 2AR-FE / FSE / FXE
The 2AR-FE engine was released in 2008 as a replacement for the 2.4 liter 2AZ-FE. The 2AR cylinder block is made of aluminium, with thin cast iron liners. The crankshaft, with 8 counterweights, is mounted 10 mm offset towards the exhaust side and drives two balance shafts. Lightweight pistons with floating pin.
A two-shaft aluminum cylinder head with hydraulic compensators is installed on a three-layer metal gasket. This head is equipped with variable valve timing on both Dual-VVTi camshafts. The phases are corrected: 50° - inlet, 40° - outlet. The camshafts themselves are driven by a single-row timing chain.
The intake has a two-stage variable length ACIS intake manifold. The exhaust uses a stainless steel exhaust manifold.
A 2AR-FSE version was also produced, with different pistons (compression ratio 13) and a different cylinder head: D4-S direct fuel injection, new camshafts, modified brains.
For hybrid Toyotas and Lexuses, the 2AR-FXE engine was produced, operating on the Atkinson cycle and equipped with other pistons (compression ratio 12.5).
Based on the 2AR, a larger 2.7 liter 1AR-FE is also produced.
Problems and disadvantages of Toyota 2AR engines
These motors are quite good in their design and do not have any obvious diseases and shortcomings. Of the less important ones: pump leaks, knocks of the VVTi clutch on a cold one (due to the characteristics of the system), these knocks can be tried to be solved by replacing the clutch. Also, the design of the engine does not provide for its repair, respectively, this is a disposable motor. On the other hand, the motor itself is not bad and reliable, with systematic maintenance, the use of high-quality oil and gasoline, the resource of a 2AR engine can be more than one or two hundred thousand km.
Tuning engine Toyota 2AR-FE/FSE
2AR Turbo. Compressor
Forget the idea of building an aspirated engine right away, this is a vegetable engine and making something sensible out of it will cost a considerable amount of money. The easiest way is to buy a 2AR-FE turbo kit based on Garrett T3/T04E (or other). These kits are mounted on stock pistons and do not require compression reduction. Don't forget to add a 63mm exhaust to that. With a boost of 0.7 bar, you will get more than 320 hp. Stock pistons can withstand more than 350 hp, but for 400+ hp. it is better to buy forged. The cost of such solutions is considerable, so it's easier to sell the car and buy a more powerful one (Camry V6 with 2GR would be an excellent choice).
The 7th generation Toyota Camry sedan (2014 restyled) is offered in Russia with three petrol engines: two four-cylinder units 2.0 (150 hp, 199 Nm) and 2.5 (181 hp, 231 Nm) liters, as well as with a 3.5-liter V6 (249 hp, 346 Nm). The base engine was recently developed and included in the lineup during the 2014 update. He replaced the old 2.0 engine, which gave power to 148 hp. and torque 190 Nm. A feature of the new 2.0-liter Toyota Camry unit is the use of a combined injection system (each cylinder has two nozzles: one in the intake manifold channel, the other directly in the combustion chamber) and the Dual VVT-iW valve timing mechanism (provides operation on the Atkinson cycle on low revs and the Otto cycle at high revs). The 2.5 and 3.0 engines have not been upgraded, so they still use the classic distributed injection and the Dual VVT-i system.
The only transmission option available for the Toyota Camry is a 6-speed hydromechanical “automatic”. The base engine working with it in tandem provides the sedan with acceleration to 100 km / h in 10.4 seconds, fuel consumption in the combined cycle is 7.2 liters. The top modification Toyota Camry 3.5 accelerates to “hundreds” in 7.1 seconds, consuming an average of 9.3 liters of fuel per 100 km.

6AR-FSE 2.0 liter 150 hp DOHC Dual VVT-iW
The new atmospheric "four" is equipped with a D-4S combined fuel injection system, which provides for the presence of two nozzles for each cylinder. Depending on the load and the speed of the crankshaft, the unit can switch to work either according to the Atkinson cycle or the Otto cycle. The special shape of the intake ports and the top of the pistons contributes to the most complete combustion of the fuel while maintaining a very high compression ratio of 12.8:1. The increase in efficiency is also provided by the Dual VVT-iW variable valve timing system, water-cooled EGR exhaust gas recirculation, a special coating of piston skirts, and a timing chain drive with reduced friction.
2AR-FE 2.5 liters 181 hp DOHC Dual VVT-i
Distinctive features of the engine are the intake manifold with variable working length (ACIS), phase change at the inlet and outlet (Dual VVT-i), roller rocker valves, piston rings with lower resistance. 
2GR-FE 3.5 liters 249 hp DOHC Dual VVT-i
For the V6 engine, technologies such as variable length intake tracts and phase shifters on both shafts are available. In Russia, the power of the unit has been cut to 249 hp, although the potential allows it to produce 273 hp. The maximum torque of 346 Nm is available at 4700 rpm. 
Engine Toyota Camry 2.5 liters of the 2AR-FE series began to be installed on the Camry after 2008. In various modifications, the power unit produces from 154 to 181 hp. Today, in our country, dealers offer Camry 2.5 with a capacity of 181 hp. Read more about this motor below. 
Camry 2.5 engine device
The in-line 4-cylinder 16-valve naturally aspirated unit has an aluminum cylinder block and a timing chain drive. For ease of maintenance in the cylinder head, the camshaft bearing housing is made separately. There are also hydraulic lifters. The motor has a variable valve timing system on both shafts. Cast iron sleeves are fused into the material of the block, and their special uneven outer surface contributes to the most durable connection and improved heat dissipation. Unfortunately, a major overhaul of an engine with a bore or sleeve is not provided. That is, after the allotted service life, or the loss of block geometry (due to engine overheating), the cylinder block can be thrown into the trash.
The VVT-i system (DVVT - Dual Variable Valve Timing) allows you to change the valve timing within 50 ° for intake and 40 ° for exhaust, which allows you to make the most efficient use of the resources of the Toyota Camry 2.5 liter engine. The EFI engine management system includes distributed, sequential fuel injection, electronically controlled throttle. Interestingly, the control of engine operating modes takes into account the presence of an anti-slip system and takes on some of the functions of the stabilization system and cruise control.
A feature of the engine can be considered the displacement of the crankshaft relative to the axis of the pistons to reduce the load on the piston group. The crankshaft has 8 counterweights on the cheeks, reduced width journals and traditional separate main bearing caps. A balance mechanism with polymer gears is driven from the crankshaft by means of a gear transmission. Look at the picture below.
Cylinder head Toyota Camry 2.5
The cylinder head is made of aluminum alloy and is made of -
1 - bearing cap, 2 - camshaft housing, 3 - cylinder head, 4 - spark plug hole, 5 - exhaust valve, 6 - intake valve. look at the picture above.
Camry camshafts are installed in a separate housing, which is then mounted on the block head - this simplifies the design and processing technology of the cylinder head itself. The valve actuator uses hydraulic valve clearance compensators and roller tappets/rockers.
Camry 2.5 engine timing drive
The gas distribution mechanism is driven by a single-row chain (pitch 9.525 mm). The hydraulic chain tensioner with a locking mechanism is installed on the inside of the cover, but has access through the service hole. The chain is lubricated with a separate oil nozzle. Timing drive diagram Toyota Camry 2.5 further in the figure.
Timing chain drive and consists of the following elements.
1 - intake camshaft sprocket
2 - damper
3 - intake camshaft
4 - exhaust camshaft
