Is the 7nr engine durable

1. Advantages and disadvantages of the nr engine: It is a very good engine, with good power, but the price is a little expensive. It is equipped with the same engine as the new Corolla. Among the two engines provided, even the slightly larger displacement of 8L maximum power is less than 103kW, the power performance is not outstanding.

2, nr. Toyota 7nr has fewer functions and does not require more 0W20 or 5W20 oil consumption, while 5nr has many functions and requires more 0W20 or 5W20 oil consumption. Toyota 7nr has a high gasoline usage rate and will not waste gasoline, while 5nr has a low gasoline usage rate and will waste gasoline.

3. The thermal efficiency of Toyota's engine code-named 7nr has reached 43%, which is quite fuel-saving, but there is no other black technology worth showing off except for good stability.

4. Is the ηr engine imported? It is imported and produced in Thailand. There is no difference between 7nr and 9nr in performance and design, but the 7nr engine is made in Thailand, the 9nr engine is domestically produced, and some accessories on the 7nr engine are imported.

Advantages and disadvantages of Toyota 7nr engine

The advantage of nr engine is that the quality and after-sales service of the engine are very perfect, and the engine material is very solid, the safety factor is very high, and the engine is powerful. The operation is stable. The disadvantage is that the fuel consumption of the engine is relatively high, and the price is also relatively expensive. The overall cost performance is not particularly high.

nr The common disease of the engine is that the fuel consumption of the engine is relatively high, and the price is also relatively expensive. The overall cost performance is not particularly high. The advantage of the 7nr engine is that the quality and after-sales service of the engine are very perfect, and the material of the engine is very solid, the safety factor is very high, and the engine is powerful and stable in operation.

nr. Toyota 7nr has fewer functions and does not require more 0W20 or 5W20 oil consumption, while 5nr has many functions and requires more 0W20 or 5W20 oil consumption.Toyota 7nr has a high gasoline usage rate and will not waste gasoline, while 5nr has a low gasoline usage rate and will waste gasoline.

The thermal efficiency of Toyota's engine reaches 43%. An engine that can exceed 40% is already a very energy-saving engine. Toyota engines are characterized by fuel-efficient and durable, but the power is relatively average.

What engine gearbox does Toyota YARiSL use

Toyota YARiSL uses a 5L inline 4-cylinder naturally aspirated engine code-named 7NR-FE The motor, the transmission part is a 5-speed manual and CVT gearbox.

Toyota YARiSL adopts the code name 7NR-FEThe 5L in-line 4-cylinder naturally aspirated engine, the transmission part is matched with a 5-speed manual and CVT gearbox. Toyota YARiSL dazzling engine Toyota YARiSL Zhixuan is equipped with a 5L inline 4-cylinder naturally aspirated engine code-named 7NR-FE, with a maximum power of 110 horsepower and a peak torque of 138 Nm.

Toyota YARiSL enjoys a 5L self-aspiration engine and a stepless gearbox. We can know that this car only costs about 100,000 yuan. The model looks simple and good in all aspects. The Toyota YARiSL engine is only 5 liters in terms of car engines.

Toyota YARiSL enjoys a 5L self-aspirated engine and stepless gearbox. We can know that this car only costs about 100,000 yuan to buy, and the model of this car looks simple and simple, and it is also good in all aspects.

Yes, Toyota's gearbox and engine are very good, and it is a famous Toyota in the world that can't break down.

L2b and 7nr engine comparison

1. Even if it is the 2021 Buick Engrave, this L The 2B engine is far from advanced.Multi-point injection technology is still adopted, and the cylinder material is still cast iron. Although the interior of Yinglang is still simple, the interior materials are obviously worse.

2. The advantage of the nr engine is that the quality and after-sales service of the engine are very perfect, and the material of the engine is very solid, the safety factor is very high, and the engine is powerful and the operation is stable. The disadvantage is that the fuel consumption of the engine is relatively high, and the price is also relatively expensive. The overall cost performance is not It's very high.

3. Because it is a cast iron engine, the service life of the l2b engine is relatively durable. As long as it is properly maintained, the service life is still very long, and it is still no problem to use 600,000 kilometers normally. The power of the L2b engine is also very strong. For example, the engine carried by Xinlechi has nearly 4L of power at 2L displacement.

4. However, even so, the comprehensive average fuel consumption of this car is not low, which are: 4L per 100 kilometers 7 liters and 6L 100 kilometers 5 liters respectively. For an A0-class car, the fuel consumption is not low.

7nr engine parameters

1, nr engine parameters 81kw/6000rmp, maximum torque 136Nm/4200rmp. There are two main technologies: DOHC overhead double camshaft: double overhead camshaft, the camshaft is located on the cylinder head. In this structure, the camshaft directly drives the rocker arm, eliminating the support column and putter, which greatly reduces the mass of reciprocating movement.

2. [Pacific Automobile Network] The engine model of Guoliu Automobile is 7NR. The engine is a 5L naturally aspirated engine with a maximum power of 81KW and a maximum torque of 138NM.The engine model of Guoliu Automobile is 7NR. The engine is a 5L naturally aspirated engine, with a maximum power of 81KW and a maximum torque of 138NM.

3. Specific parameters: the maximum power of 3L is 63KW (86PS), the maximum torque is 121N·M, and the maximum speed is 168KM/h (manual transmission); the maximum power of 6L is 87KW (118PS), the maximum torque is 150N·M, and the maximum speed is 19 5KM/h.

Zhixuan engine 7NR common disease

Zhixuan's common disease I: low playability As we all know, the predecessor of Zhixuan is Yaris, a model with playability that is not lower than Fit at all.

The common diseases of dazzling are: small skylight;The armrest capacity is small and cannot hold items; when the car is driving fast, the wind noise and engine noise are obvious, and the sound insulation effect is poor; the suspension is stiff, and there will be an obvious bumpy feeling when passing through the speed bump; the softness of the seats in the car is low.

If it goes on for a long time, it will cause a strain on the cylinder wall or even burst the cylinder. In the end, the engine can only be disassembled for overhaul.

Power comparison Toyota Zhixuan X is equipped with a 5L naturally aspirated engine, with a maximum power of 82KW, a maximum horsepower of 112 horsepower, and a peak torque of 139Nm. Such power is enough to drive on low-speed roads, but it is a little weak to drive at high speed, especially when you want to overtake, it is difficult to accelerate quickly. The configuration is too bad.

Toyota Zhixuan 5L and 3L engines are 7NR and 6NR engines respectively. The displacement and power of the two engines are different, but they are relatively stable.Zhixuan engine: (1) power: the power output is relatively gentle, and the 4AT performs well; (2) acceleration test: 174 seconds; (3) brake test: 463 meters.
