Toyota 1zz engine parameters

The cylinder diameter of this engine is 79mm, and the stroke is 95mm; the compression ratio is 10:1. The maximum horsepower announced in Taiwan is 136PS/6000rpm, and the maximum torque is 14kgm/4200rpm.

zz cylinder diameter is 79mm, stroke 95mm, 8 displacements. The compression ratio is 10:1, all-aluminum, with VTT-i, the maximum horsepower is 136 PS/6000rpm, and the maximum torque is 14kgm/4200rpm. It is mostly used in corollas in China. 1nz Bore is 75 mm and stroke is 87 mm, 5 displacements. All-aluminum.

Yes, the 1zz engine is a naturally aspirated engine. Many engines are only variable intake, while this engine is dual variable inlet and exhaust. It is mostly used in Toyota cars 1zz engine parameters. The engine cylinder diameter is 79mm, and the stroke is 9, which is super cost-effective.

How many kilograms of cylinder pressure does the Toyota Corolla 1ZZ engine need to start?

The pressure data of the cylinder varies depending on the model. Generally, large cars (such as Dongfeng 140 and Jiefang 141) weigh 6-8 kg, and small cars weigh more than 8 kg. If it is below the normal pressure, it can be judged that the engine is faulty. Because the cylinder diameter and stroke of different cars and models are different. So this data is also different.

Most large cars (such as Dongfeng 140 and Jiefang 141) are 68kg, and it is normal for small cars to weigh more than 8kg. If it is below the normal pressure, it can be judged that the engine is faulty. Because the cylinder diameter and stroke of different cars and models are different. So this data is different.

The maximum burst pressure of the engine is 160 kg. The engine burst pressure gauge is installed on the engine, and then the start switch is turned on. After the pressure gauge pointer reaches the maximum stability value, the compression pressure value is read, the check valve button is pressed to reduce the exhaust pressure, and each cylinder is measured twice to take the average value.

The spark plug can burst out strong timing sparks; there is sufficient cylinder pressure; the concentration of combustible mixture is appropriate. If the car is charged but does not ignite, first check whether the voltage is sufficient.Under normal circumstances, the battery voltage should be 12V. When starting, the voltage will drop to about 11V because the starter and spark plug need to be powered.

Is the Toyota 1zz engine imported?

1. Yes, the 1zz engine is a naturally aspirated engine. Many engines are only variable intake, and this engine is dually variable inlet and exhaust. It is mostly used in Toyota cars 1zz engine parameters. The engine cylinder diameter is 79mm, and the stroke is 9, which is super cost-effective.

2. No, the engine you mentioned should not be an imported engine, but some new domestic engines.

3. At present, most Toyota engines are domestic, but they use foreign technology.Take Corolla as an example, it uses FAW Toyota's domestic small-displacement engine. The displacement is not as high as Corolla, and it is also very fuel-efficient. This engine is the first domestic small-displacement engine, and the specific model is 1ZR-FE.

4. GAC Toyota Engine Co., Ltd. is the engine part of the overall cooperation project between Guangzhou Automobile Group Co., Ltd. and Toyota Motor Company. The cooperation of its whole vehicle project has been submitted to the state for approval. It took GAC Toyota Engine Co., Ltd. less than a year from the confirmation of the joint venture intention and the conclusion of a cooperation agreement to the project's approval by the state.

5. Take GAC Toyota as an example, some of its models are equipped with engines from Toyota, Tokyo, Japan, such as Rayling Twin E+, Zhixiang, Corolla and other models, and almost all of these engines are imported.At the same time, some engines of GAC Toyota are also domestically produced, such as Camry, Prado and other models.

6. Corolla engine is made in China, technology is imported. The engine is assembled by Tianjin FAW Toyota Engine Co., Ltd., and the technology is provided by Toyota.

Why are the current joint venture engines not as good as domestic ones?

1. It is definitely impossible. It's not that the engine technology is not good, but that the control dimension of the whole vehicle is not good. This is the biggest difference between domestic cars and joint venture cars.

2. This is also the reason why many independent brands are still using imitation engines, because the imitation cost is relatively low. It is true that your own brand engine lacks power and high fuel consumption, but that's a thing of the past.Nowadays, most of the independent brand engines have good power, and most brands have entered the stage of independent research and development and production.

3. Generally speaking, the production technology of domestic engines is relatively average and the development time is relatively short; while the technology of joint venture engines is relatively advanced and the development time is relatively long. However, with the progress of China's car-making technology and strength, many famous engines have also appeared in China.

4. If we compare the latest domestic engines with the world's mainstream engines, there are gaps in performance, thermal efficiency and technology, but domestic brands have also achieved results in their exploration in recent years.
