5afe Which cars are installed in the engine?

Toyota Wichi. The engine model used by Toyota Vios is 5AFE, which is a 5L naturally aspirated engine. Vios is a family entry-level model specially designed and developed by Toyota for the Asian market. Based on NBC's platform, after lengthening the wheelbase, Vios developed on the small car platform has reached the level of a compact sedan.

Wichi is an entry-level model designed and developed by Toyota for the Asian market. On account ofThe NBC platform, which was developed on the small car platform, almost reached the level of a compact car after lengthening the wheelbase.

Toyota has now launched the Vechi car. In addition to being praised by netizens in terms of appearance design, it has also improved its power. Its engine adopts 3-liter and 5-liter naturally aspirated motors, and the horsepower can reach 99 to 107.

Lewei's listing once impacted the sales of Fit, Maxima, Sienna and Carnival, which is also a good choice among economical family cars. At present, Willard is equipped with Toyota 5A-FE and Toyota 8A engines.

nr and 5nrfe engines are both Toyota NR series engines, and there is no difference in essence. The number in front is the sequence identification number, in order to distinguish between GAC Toyota and FAW Toyota.At present, GAC Toyota's Zhixuan is equipped with a 7NR-FE engine, and FAW Toyota's Vechi is equipped with a 5NR-FE engine.

5a and 8a engines universal?

The mechanical structure of these two engines is basically the same: water-cooled 4-stroke 4-cylinder 16-parter electric injection gasoline engine, closed-loop multi-point electronically controlled fuel injection.The difference is the displacement: Toyota 5a displacement: 1498ml, Toyota 8a displacement: 1342ml.

The mechanical structure of these two engines is basically the same: water-cooled 4-stroke 4-cylinder 16-balte electric injection gasoline engine, closed-loop multi-point electronically controlled fuel injection.

Therefore, there are later 8A+ and 5A+, which do not need a distributor. As for other engines that imitate the 8A, they are not completely imitated, but have been improved. Finally, I would like to add: the engine technology of 8A has fallen behind. Of course, there is still room for improvement, but it is not big.

The mechanical structure of the A engine is basically the same as that of the 8A engine: water-cooled 4-stroke 4-cylinder 16-bar electric injection gasoline engine, closed-loop multi-point electronically controlled fuel injection. The difference is the displacement: Toyota 5A displacement 1498ml, Toyota 8A displacement 1342ml.In terms of power output, Toyota 5A has a larger displacement than 8A, and the power torque is naturally higher.

When adjusting the valve gap with the two-adjustment method, how to distinguish the valve that can be adjusted by the Toyota 5A engine...

The two-adjustment method is to shake the crankshaft to make the first cylinder piston at the compression stop point, and the flywheel mark is right with the check hole. At this time, the engine valve can be adjusted, shake the crankshaft around, so that The six-cylinder piston is at the stop point on the compression stroke, and then adjust other valves.

The first method is the adjustment method of each cylinder. That is, according to the ignition order of the cylinder, after determining that the piston of a cylinder is in the compression stop position, the valve gap between the intake and exhaust of the cylinder can be adjusted.After adjustment, turn the crankshaft and use this method to gradually adjust the valve clearance of other cylinders.

"The relevant content is introduced as follows: the method of adjusting the valve gap in the engine: the method of adjusting the valve gap twice, that is, turning the crankshaft twice to complete all the valve clearance adjustments.

There are two common methods of valve gap checking and adjustment: one is the cylinder-by-cylinder adjustment method, that is, according to the ignition order of the cylinder, after determining the stop position of a cylinder piston on the compression, the intake and exhaust valve gaps of the cylinder can be adjusted; after adjustment, shake the crankshaft and gradually adjust the valve gaps of other cylinders according to this method.

According to the working order of the engine, determine the adjustable valve according to the principle of "double, row, not, advance", and then check and adjust the valve gap; (3) Turn the crankshaft one more lap,Align the timing mark, check and adjust the remaining valve gaps in the same way, and then all valves have been checked and adjusted.

The cylinder-by-cylinder method requires more crankshafts to be shaken, and it takes more time to check and adjust. However, for engines with severe wear, the cylinder-by-cylinder method is more accurate to check and adjust the valve gap.

How about the Wichi 5a engine

1. What engine does Toyota Wichi use? How about the 2014 Toyota Wichita engine? The engine model used by Toyota Wichi is 5AFE, which is a 5L naturally aspirated engine. .

2. The Vios engine is equipped with a domestic 16-valve 5A-FE engine. In addition to the increase in the piston stroke and the displacement increased from 3 liters to 5 liters, it is almost exactly the same as the domestic 8A engine, and the corresponding maximum power is also increased to 68kw.The transmission system is equipped with a 5-speed manual transmission from Aisin and a 4-speed automatic transmission with optimized transmission ratio.

3. OK. The 5A engine adopts advanced fuel injection technology, which can effectively reduce fuel consumption and improve fuel utilization, so as to achieve good environmental protection effects.

4. The main performance of common faults of the Vechi engine. Judging from the information obtained from the car quality network, the key common fault problems of the two engines of Toyota Vichi depend on vibration and abnormal noise, especially when it is within 1000 rpm.

5. In fact, the original 5A engine of Vechi is quite powerful, especially the low torque is very abundant. Daily driving is not weak, but the noise is relatively obvious every time it reaches medium and high turns, giving people a sense of not being advanced and perfect.

6. Of course, 5A+ is good. After all, it has been upgraded.The old car is fuel-efficient and more economical, but the power is not as stable as the old car when driving at high speed.
