Which is better, Wuling B2 or L4 engine? What is the difference in performance

Wuling's l2b engine has the characteristics of high power, low fuel consumption, high quality and so on. The l2b engine is a typical new generation of small-displacement high-power engine. Because it is a cast iron engine, the life of the l2B engine is also relatively durable.

In addition, the second row of seats also supports a horizontal 160mm and a vertical 560mm movement range, which is practical.

In terms of technical parameters, the LMH engine has higher power output and fuel economy than the L2B engine. At the same time, the LMH engine adopts advanced cylinders.The internal direct injection technology and variable valve timing system have improved its combustion efficiency and emission control.

Slight advantages in width and height. Secondly, in terms of power, 0 is equipped with a 5T L4 engine, with a maximum power of 147 horsepower and a peak torque of 250 Nm. 5 Equipped with a 0L L4 engine, the maximum power of the engine is 133 horsepower and the peak torque is 200 Nm. The comparison situation is still 0.

What is the principle of the engine of the B2 stealth bomber?

1. The "fire nozzle" should be the "engine nozzle", right? The B-2 bomber has an engine nozzle, but it is very hidden.

2. This is a mechanical device that generates an electric charge by rubbing the rubber band.The B-2 uses a jet engine with an appropriate device. The secret is to mingeg negative ions into the gas flow to interfere with the electrostatic balance of the flame and charge the front edge at the same time.

3. Do you think the pneumatic layout of the B2 aircraft is extraordinary? Let me tell you the principle: The B-2 bomber is equipped with four General Electric F-118-GE-100 jet engines, each of which can produce 7,854 kg of thrust. Like ordinary aircraft, the pilots of the B-2 fly the aircraft by controlling the movement of the parts on the wings.

4. Stealth aircraft is not that we can't see the sound and can't hear the invisible plane, but it can't let some bands of the radar find or the distance is very close. Let's talk about the technical principle of how not to be detected by the radar. The measurement method of radar is to emit high-frequency electromagnetic waves first. When an object exists, the object will reflect the electromagnetic waves back.

b2 Why is the engine nozzle placed on it

1. In addition, the starting mechanism is also equipped with an airflow mixer, which can introduce the cold air flowing through the wing surface into the engine and continuously reduce the engine chamber. The temperature of the outer layer. The nozzle part is wide and flat, so that people can't see the nozzle at the rear of the plane.

2. Enhance stealth performance. The B-2 bomber adopts a wing-body fusion and tailless wing configuration. The front edge of the wing is connected to the front of the aircraft, and the rear edge of the wing is jagged. The fuselage wings are made of a large number of graphite/carbon fiber composite materials and honeycomb-shaped structures. There is a wave-absorbing coating on the surface, and the nozzle of the generator is placed above the wing.

3. The tail of B2 is designed to be jagged and not drooping.Tail, and the engine tail nozzle is only open to the back and upper part, in order to avoid the detection of ground infrared detection equipment. The upper opening can accelerate the cooling of the high-heat tail nozzle airflow and avoid leaving a hot air flow belt in the air. Moreover, the engine power of B2 is relatively small, and it can only fly at subsonic speed.

4. The B-2 bomber is a long-range all-weather stealth strategic bomber developed by the United States, with 2 to 3 crew members, used to replace the B-52 bomber.

5. However, when the B-2 opens the magazine, it will destroy the overall shape, and the radar can detect it at a long distance. Of course, spears and shields are relatively developed. Now there are also anti-invisibility radars, which adopt special radar waves. Stealth aircraft cannot scatter radar waves very well, so they can still be detected at a long distance.

What engine does the B2 bomber use?

1. The B-2 "Spirit" bomber is a four-engine strategic bomber developed by Northrop Grumman in the United States, and it is also the only stealth strategic bomber in the world.

2. The B2 bomber is equipped with 4 F118 turbofan engines, and the air intake and air intake of the flying wing have been changed into a flat and curved shape, which can ensure that the on-board radar cannot be illuminated above or below the front of the engine, and the overall shape is smoother and more In the streamlined type.

3. The turbine fan engine is composed of a fan, a compressor, a combustion chamber, a high-pressure turbine that drives the compressor, a low-pressure turbine that drives the fan and an exhaust system.

How about the LB2 engine of Wuling gas car?

1. Wuling's l2b engine has the characteristics of high power, low fuel consumption, high quality and so on. The l2b engine is a typical new generation of small-displacement high-power engine. Because it is a cast iron engine, the life of the l2B engine is also relatively durable.

2. Wuling Hongguang S 2019 5L basic engine model is l2b. L2b engine performance: l2b engine has the characteristics of high power, low fuel consumption and high quality. It is a typical new generation of small-displacement high-power engine. Is it the new high-performance mini car of New Lechi that is still very durable? As an entry-level model, the configuration of the new car is more economical.

3. Baojun 510 car uses an L2B engine. This engine uses the engine of SAIC General Motors, which is better. Its disadvantage is that it is easy to have high water temperature, while the LAR engine is easy to leak oil. They are almost the same, each with its own advantages.
