What is the difference between the new Santana and the new Jetta engine?

1. Jetta and Santana are built on the same platform, and the appearance of the two cars is almost the same. But the powertrain of these two carsIt's different. The new Jetta uses a total of two engines, one is a 4-liter naturally aspirated engine, and the other is a 5-liter naturally aspirated engine.

2. There is very little difference between Jetta and Santana. Jetta belongs to FAW Volkswagen, and Santana belongs to SAIC Volkswagen. Jetta is equipped with two engines, and Santana is equipped with only one engine. Jetta is equipped with two engines, one is a 4-liter naturally aspirated engine and the other is a 5-liter naturally aspirated engine.

3. EA211 is Volkswagen's new generation of engine series, which is a typical representative of its blue drive technology. The important difference between it and EA111 is the all-aluminum body and the active cylinder management system (ACT), that is, the application of the cylinder shutdown system. This new engine will be about 15 kilograms lighter than EA111 and save about 8 to 10% of fuel consumption.

4. There is not much difference between Santana and Jetta. The main difference is that Santana belongs to SAIC Volkswagen, and Jetta belongs to FAW Volkswagen. In addition, Santana and Jetta will also have slight differences in vehicle price, power and body size. The specific instructions are as follows. Car price: The price range of Santana is 690,000 yuan to 1.59 million yuan.

5. The engines used in the three cars are the same, all of which are EA211 engines, and the gearbox is also the same, whether automatic or manual. The interior space and wheelbase of the car are the same. The chassis and accessories are also the same.

6. EA111 is a cast iron engine, and EA211 is an all-aluminum engine, which is lighter in weight and has better fuel consumption performance. In addition, the EA111 adopts a timing chain, which has lower noise and longer service life than the timing belt of EA211.The EA211 return to the original belt is mainly based on the consideration of cost reduction.

PS-90A development

1, ПC-90A was set up by Solovyev of the former Soviet Union The Planning Bureau (now the Russian Perm Aviation Engine Scientific Research and Production Consortium) developed and produced the large-culvert ratio turbine fan engine.When the development began in 1979, the thrust of the ПC-90 engine was 13440daN.

2. PS-90A is a turbine fan engine designed and produced by the Soloviev Design Bureau of the former Soviet Union, which is mainly equipped with Russia's Il-96-300 passenger aircraft, Tu-204 passenger aircraft and Il-76 military transport aircraft.

3. The biggest highlight of the Il-78M-90A is the PS-90A-76 turbofan engine it uses.

4. There are four main modifications. The basic PS-90A, PS-90A-7PS-90APS-90A2 and PS90A3 PS-90A3 are improved versions of PS-90A2.

5. Compared with the A-50, the A-100 has made significant improvements.First of all, the carrier platform of the A-100 early warning aircraft has been improved. The new A-100 early warning aircraft is modified based on the Il-76MD-90A military transporter platform, which adopts the PS-90A turbine fan engine.

6. In addition, there is also a 350-seat modified model called Il-96-350, whose fuselage is lengthened and is scheduled to fly for the first time in 1993. The following situations apply to Il-96-300. The power unit is four Solovyev PS-90A turbofan engines, with a single thrust of 157 kN, and a reverse thrust device.

Why is the vortex fan 20 and ps90a good?

1. Because it is a new design,Theoretically, the turbofan 20 should be more advanced than the PS-90 (mainly the thrust-to-weight ratio, life and fuel-saving), and the test flight has been explained to be relatively smooth, but it is too early to draw a conclusion.

2. As for Russia, of course, there are also engines that are better and more suitable for transporting 20, such as PS-90A, which is the engine used by the Figure 204 passenger aircraft and Il 476, but they have always been wary of China obtaining its relevant technology, so they have always refused to sell it to China.

3. Of course, Russia also has a better and more suitable engine PS-90A than this one, which is the engine used by the Figure 204 passenger plane and Il 476, but they have always been wary of us obtaining his relevant technology, so they have never sold it to us.

4. The only shortcoming is that the Il-76MD-90A transport aircraft is equipped with a PS-90A large culvert ratio engine. The performance of this engine is obviously higher than that of the D-30KP2 turbofan engine, so the Yun-20 needs to be replaced with an engine to fully surpass the Il-76MD-90A.

Why is the Fit called Super Run

1. Because the original Fit engine has a power increase of 90PS and a maximum power speed of 6,600 rpm, it is called a super run. When it comes to Fit, I believe many car owners will think of GK5. In the eyes of Fit fans, this car is not an ordinary family car. Although it is a hatchback, the power performance is very good. It is a hatchback that can bring people passion.

2. Because the lift power of the original engine of Fit is 90PS, and the maximum power speed is 6600rpm, it is called super running.

3. gk5 is the third-generation Fit. The reason why this car is called supercar is that the horsepower of this car is the largest in the same class. This car accelerates faster than the polo gti in the original state. And the modification potential of Fit is very high, so this car is called supercar by many netizens.

Design and development of PS90 turbofan engine

1. With the demand of the former Soviet Union for a new generation of passenger aircraft, the Soloviev Design Bureau of the former Soviet Union began to design and develop the PS-90 high duct ratio for commercial use. Turbofan engine to meet the most economical, safe and stricter exhaust emission requirements.Compared with the former Soviet engine designed and produced in the 1960s, the PS-90 has shown great progress.

2, ПC-90A is a large duct ratio turbine fan engine developed and produced by the Solovyev Design Bureau of the former Soviet Union (now the Russian Perm Aviation Engine Scientific Research and Production Consortium). When the development began in 1979, the thrust of the ПC-90 engine was 13440daN.

3. There are four main modifications. The basic PS-90A, PS-90A-7PS-90APS-90A2 and PS90A3 PS-90A3 are improved versions of PS-90A2.

4. PS90 turbofan engine. PS-90 is a high-duct ratio turbine fan engine produced by the Soloviev Design Bureau of the former Soviet Union of the Russian aircraft parts manufacturing group.

5. The turbofan engine was developed under this demand. In fact, the simple understanding is that several turbines are added in front of the turbojet engine, and these cargo ships are driving a certain number of fans. The design of the two culverts is to redistribute the energy of the gas to the fan and the combustion chamber respectively.

6. And General Electric's rear fan design completely avoids these three main difficulties at once. The rear fan of CJ805-23 is actually a double-section blade. The lower half of the blade is a turbine blade and the upper half is a fan blade. Such a blade is placed at the tail of the inner-hanging core engine like a free turbine activated by a vortex shaft.
