The latest engine versions after were equipped with a VVTi Variable Valve Timing system for the intake camshafts. Bore and stroke are Compression ratio rating is From the front of the RH bank cylinders are numbered 1—3—5, and from the front of the LH bank cylinders are numbered 2—4—6.
The engine has press-fitted cast-iron cylinder liners. The cylinder block contains a water jacket, through which coolant is pumped to cool the cylinders. The crankshaft is supported by 4 bearings inside the crankcase.
These bearings are made of copper and lead alloy.Pk sela
The crankshaft is integrated with 9 semi counterweights for balance. Oil holes are placed in the center of the crankshaft for supply oil to the connecting rods, bearings, pistons and other components.
Pistons are made of high temperature-resistant aluminum alloy. Piston pins are the full-floating type, with the pins fastened to either the piston boss nor the connecting rods.
Instead, snap rings are fitted on both ends of the piston pins, preventing the pins from falling out. The first compression ring is made of steel and the second compression ring is made of cast iron. The oil ring also is made of a combination of steel and stainless steel. The outer diameter of each piston ring is slightly larger than the diameter of the piston and the flexibility of the rings allows them to hug the cylinder walls when they are mounted on the piston.
The cylinder bore is The cylinder head is made of aluminum alloy, with a cross-flow type intake and exhaust layout and with pent-roof type combustion chambers. The spark plugs are located in the center of the combustion chambers. The exhaust camshafts are driven by a single timing belt, and a gear on the exhaust camshaft engages with a gear on the intake camshaft to drive it.
The camshaft journal is supported at 5 places between the valve lifters of each cylinder and on the front end of the cylinder head.Sun jupiter ketu conjunction in 11th house
Lubrication of the cam journals and gears is accomplished by oil being supplied through the oiler port in the center of the camshaft. Exhaust and intake valves are equipped with irregular pitch springs made of special valve spring carbon steel which are capable of following the cam profile at all engine speeds.
The intake valve diameter is Adjustment of the valve clearance is done by means of an outer shim type system, in which valve adjusting shims are located above the valve lifters. This permits replacement of the shims without removal of the camshafts.Sign In with Edmunds. Howdy, Stranger! It looks like you're new here. If you want to get involved, click one of these buttons!

He replaced the plugs, but says I also need an ignition coil. What is the numbering sequence in the coils? I'm going to replace it myself and don't know which one is 2. Best Answers.Toyota's 3. The new engine very soon became a popular choice for mass-produced Toyota's vehicle such as Toyota Camry, Toyota Rav4, and Highlander.
The V-angle between cylinder banks is 60 degrees. The liners are cast into the block material. The engine has a forged steel crankshaft with five counterweights and forged connecting rods.
The aluminum alloy pistons have resin-coated skirts to reduce friction. The engine block is equipped with oil jets which spray oil on the pistons and reduce their temperature. Each cylinder head is a three-piece unit: the cylinder head itself, the camshaft housing, and the valve cover. All components are made of aluminum alloy. There are steel-laminate type head gaskets between cylinder banks and heads. The engine has double overhead chain-driven camshafts the intake and exhaust camshafts for both cylinder banks.
The primary timing chain drives the intake camshafts only; the exhaust camshafts are driven by intake camshafts via secondary chains. The valves are actuated via roller rocker arms. The valve clearance is automatically adjusted via hydraulic lash adjusters tappets. The 2GR engine has a variable geometry intake manifold made of plastic. The Toyota's ACIS varies the length of the intake manifold according to engine rpm by open and closes the intake air control valve.
The acceleration pedal doesn't have a physical connection with the throttle body, just position sensor, and wires. Each spark plug has an individual ignition coil integrated into the spark plug cap.
The exhausts gases go out through the stainless-steel exhaust manifolds headers and a three-way catalytic converter on both sides. That version features Toyota's D-4S twin injection system direct and port fuel injection.
The combination of the direct injection and conventional port injection requires separate low- and high-pressure fuel systems. The engine also got new cylinder heads with high-pressure direct fuel injectors positioned at the outer side of the intake valves.
The pistons have redesigned shape and are made of a hypereutectic aluminum alloy to withstand high loads. Due to the ability to provide better cooling of air-fuel mixture by direct fuel injection into the combustion chamber, the compression ratio was increased up to But a few years later, this engine became a standard V6 engine for the Toyota Camry and Highlander.
The engine kept the architecture and received the last Toyota's advanced technologies in the engine development. The engine still uses a variable exhaust valve timing VVT-i. The significant changes are observed in the exhaust system. Now, the exhaust manifolds are integrated into the cylinder heads and the EGR circuit is cooled. The reason for that became a problem with an oil leak from the rubber hose which feeds the VVT-i lubrication system.
The manufacturer replaced that rubber part by a metal pipe. If the 2GR engine has a damaged cylinder wall surface, the entire cylinder block has to be replaced. The thin walls of the cylinder liners make the engine impossible to bore the block.
The liners itself are cast into the aluminum engine block. That is caused by the design flaw. The problem leads to high oil consumption at first and scratches appearance on cylinder wall later. If you read above, now you know the expensive end of that story. The all GR family has a common problem with unreliable water pump and ignition coils.
In some cases, they don't last longer than k miles, and that is very annoying. The 2GR-FE has longevity aboutmileskm.A part of understanding the basics of a V8 engine is to know how the cylinders are numbered. According to BoxWrench, "Cylinder numbering refers to how the bores within the block are oriented and numbered.
A V8 engine has eight cylinders, with one cylinder placed beneath each spark plug below the two valve covers on each half of the engine. Four cylinders sit on both the right and left sides of the engine, for a total of eight. To determine the location of parts on a car or truck or its engine with regard to left or right side, the accepted method is from sitting inside the car. When looking at the V8 engine for cylinder placement, keep in mind that and references to the right and left side of an engine will be reversed, when compared with sitting inside the car.
There is not one standard method for having the cylinders numbered on a V8 engine. Each manufacturer chooses its own system, or uses a basic method shared by other manufacturers, since this is not necessarily considered a proprietary element in the operation of an engine or its design.
In the most common method for cylinder numbering of a V8 engine, when facing the engine from the front of the car, the cylinder on your actual right side and closest to you is the number one cylinder. Then jumping to your actual left side, the closest cylinder to you is the number two cylinder.
This back and forth counting continues in this pattern for all eight cylinders. In effect, all odd-numbered cylinders are on your actual right side, while all the even numbers are on your left side. Basically if the V-sides of the engine were folded into each other, the cylinder numbers would fall inline and in order. Ford Motor Company numbers its cylinders along each side from front to back.2007 Toyota Camry V6 2GR-FE 3.5L Spark Plug Replacement
When looking at the engine, start on your actual left-hand side with the cylinder closest to you as number one, followed by two, three and four. Then look to your actual right-hand side; the cylinder closest to you is number five, moving along the line away from you to number eight. The cylinders in any engine, V8 or otherwise do not all fire at the same time.
Each cylinder takes its turn in a predetermined rotation, which is not the same order as the cylinder numbering. According to BoxWrench, the basic Ford firing order is as follows: First cylinder number one, followed by five, four, two, six, three, seven and finally number eight; then the rotation begins again and continues while the engine is in operation.
The firing order may change between models, even when the manufacturer uses a standard firing order for other modes. Its always best to check the owner's manual for specific firing order.

Now that the RAV4 has been announced, we can read the tea leaves. The V6 is over forever in the RAV4. However, that does not mean the 2.
That was pretty much an accident.
I need the firing order
Still, for those lucky owners that opted for the V6, it was a pleasant one. It was middle of the road. However, time marches on. Fuel economy is often one of the top criteria shoppers now consider when selecting a vehicle. The percentage of takers was low and getting lower. Standardizing on a 4-cylinder engine bay keeps things simple.
For those that want a smidge more power and also better fuel economy, the new RAV4 Hybrid might do. For those that want a Toyota-family of brands vehicle with more power the Lexus NXt and its 2. One could argue that the RAV4 with a V6 might be better in some ways than either of these new choices, but the NXt is also selling strongly. In fact, since it entered production it has outsold the BMW X3 every month.
Like many RAV4 owners I also own a 6-cylinder, compact Toyota crossover from that generation, mine being a Highlander. It is easy to understand why the owners of the older RAV4 V6 miss it, but based on what Toyota and Lexus are saying and doing, there is no evidence it is ever coming back. More on Page 2.
