What about L2B engines? Engine model L2B is several cylinders

L2B engines are characterized by high power, low fuel consumption, and high quality.

It is a typical new generation of small-displacement high-power engine. Since 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 no problem to use it normally for 600,000 kilometers.

The L2B engine is also very powerful, such as the engine equipped in the new music pit has close power when displacement. The maximum power is the highest level of the A00 class mini vehicle engine with a displacement below in the domestic market.

The L2B domestic production displacement is available in two types, and many models of the domestic and GM joint ventures use engines codenamed L2B.

There are two series of L2B, PTRC and STEC in use, but they are still different because the R&D team and production area are different. L2B is the direct use of GM's old machine, PTEC can be understood as an upgrade on the basis of the old L2B, and STEC can be understood as an upgrade on the basis of PTEC.

Therefore, L2B is mostly used in old models, PTEC is mostly used in domestic cars, and STEC is used in GM joint venture cars, after all, there is a difference in car prices, and the engine must not be exactly the same.

Universal L2B (Excelle.

From 2013, from 2015, Cruze.

2015 Classic) This engine was first in the Baojun.

The test on the sedan, 2 years later, it was equipped with Kaiyue, the test was good, so the Yinglang facelift also used L2B, features: low torque power, DVVT timing, cast iron engine, durability.

Engine model L2B is four-cylinder.

L2B series engine is the engine developed by General Motors of the United States, speaking of this engine, you may be a little unfamiliar, but when it comes to the models it carries, it is definitely familiar to you, such as Kaiyue, New Yinglang, Baojun 730, classic Cruze, Wuling Rongguang, just these cars, the total sales of that year can circle the earth three times.

The L2B engine has a displacement of liters, a maximum horsepower of 112, a maximum power of 82 kW, a maximum power of 5800 Nm, a maximum torque of 147 Nm, and a maximum torque of 3600 to 4000.

The advantages and disadvantages of the L2B engine are very obvious, because this engine is available in two versions, so the characteristics reflected in the different models will be different. The advantage of the L2B engine is that the leather is solid and thick, which is common to both Wuling and Buick, and I believe everyone has no opinion on this. However, the L2B equipped on Buick will obviously be better than Baojun and Wuling in terms of power.

The shortcomings of the L2B engine are also obvious, that is, the same platform, but the technical differences are relatively large, for example, the general engine quality is stable and reliable, the acceleration noise is small, the transmission is strong, and Wuling is a van The engine is noisy and the technical level is poor, but this is also determined by their respective brand positioning.

The above content reference: Owner's Guide - Common problems and advantages and disadvantages of L2B engine, L2B engine is the best production.

It's OK.

GM's new engine, displacement, low idle speed, fuel economy, at the beginning is not very adaptable, because the starting control is not easy to control, slowly get used to it. So far, there's nothing wrong with that.

Technical characteristics of the engine:

1. The engine valve drive mechanism adopts the hydraulic support ball rocker arm structure, and the engine working principle is compared with the hydraulic tappet valve drive mechanism commonly used in the general gasoline engine, this novel valve drive mechanism has the advantage of relatively small friction torque, so the required driving force is also small, so that the engine power consumption can be effectively reduced and fuel consumption can be reduced.

2. In order to effectively reduce the weight of the whole vehicle, the 1 4-liter gasoline engine adopts aluminum alloy cylinder block, which has achieved a very obvious lightweight effect.

3. The use of special materials and plastic intake pipes processed by special technology instead of traditional metal intake pipes not only receives lightweight effects, but also can effectively reduce the resistance of the intake pipe wall, improve the intake efficiency, and increase the engine power.

4. The expansion and breaking connecting rod processed by advanced technology is expanded and broken by using special expansion and breaking equipment, instead of the original sawing and grinding process. This makes use of the jagged "huff" surface of the expansion and breaking link to ensure an absolutely accurate tight fixing position, which reduces friction and extends the service life of the linkage.

5. Compared with the original camshaft, the hot-sleeve camshaft can not only reduce the weight of the camshaft, but also achieve higher cam profile accuracy and more accurate valve timing for the engine (Fig. 6).

6. The throttle adopts an electronic control device, also known as e-gas electronic throttle, which can unify and coordinate and reasonably manage the instantaneous requirements of the engine torque and output power under various working conditions of the car, such as the driver accelerating, overtaking, starting the air conditioning, etc., which can make the engine always in the best range at each working point, which can not only meet the requirements of low emission and low fuel consumption, but also optimize the driving performance of the whole vehicle.

Review:L2B series engine is the engine developed by General Motors of the United States, speaking of this engine, you may be a little unfamiliar, but when it comes to the models it carries, it is definitely familiar to you, such as Kaiyue, New Yinglang, Baojun 730, classic Cruze, Wuling Rongguang, just these cars, the total sales of that year can circle the earth three times.

It is understood that the production place of L2B engine is Shanghai GM Dongyue Automobile Powertrain ****--- Yantai, this production base is a new joint venture established by General Motors China in China, located in Yantai Economic and Technological Development Zone, Shandong Province. The factory covers an area of 10,000 square meters and has five major processes: engine, gearbox, casting, forging and aluminum casting.

The L2B engine is produced at Shanghai GM Dongyue Automotive Powertrain. The shortcomings of the L2B engine are also obvious, that is, the same platform, but the technical differences are relatively large, for example, the general engine quality is stable and reliable, the acceleration noise is small, the smooth transmission is powerful, and Wuling is a van The engine is noisy and the technical level is poor, but this is also determined by their respective brand positioning.

The 2B series engine is an engine developed by General Motors in the United States, speaking of this engine, you may be a little unfamiliar, but when it comes to the models it carries, it is definitely familiar to you, such as Kaiyue, Xinyinglang, Baojun 730, classic Cruze, Wuling Rongguang, just these cars, the total sales of that year can circle the earth three times.

It is worth mentioning that although the engine on the Buick model Chunzhou is from the same prototype engine as Wuling Rongguang and Baojun, due to the brand status, the power parameters and performance of the L2B engine on these models are different. For example, you will find that the Baojun has the word "P-TEC" on the bonnet, while the Kaiyue and Yinglang are "S-TEC", and although the P-TEC engine and S-TEC both belong to the L2B series, the S-TEC is a more advanced version of the Jingsen cracked book.

The advantages and disadvantages of the L2B engine are very obvious, because this engine is available in two versions, so the characteristics reflected in the different models will be different. The advantage of the L2B engine is that the leather is solid and thick, which is common to both Wuling and Buick, and I believe everyone has no opinion on this. However, the L2B equipped on Buick will obviously be better than Baojun and Wuling in terms of power.

1. The intake manifold is abnormal, and when you step on the accelerator and accelerate sharply, there will be a continuous sound similar to a gas stove ignition in the engine compartment, and the sound will disappear after you release the accelerator. Later, many people found out that the vacuum one-way suction valve of the intake manifold was damaged, so when this problem occurs, only one one-way suction valve needs to be replaced to solve the problem.

2. The intake manifold of the L2B engine has been in a high temperature state for a long time, and the diaphragm of the vacuum valve has aged very quickly.

The LL2B engine is characterized by high power, low fuel consumption and high quality, and is a typical new generation of small displacement and high power engine.

The L2B has plenty of low-torque power, DVVT timing, and a cast iron engine for durability. The S-TEC series is stable and reliable, with low acceleration noise and smooth and powerful power transmission. Thanks to DVVT technology, the L2B's valve phase has been changed, so that L2B has better fuel economy and power at low speeds.

Because it is a cast iron engine, the life of the L2B engine is also relatively long, the L2B series engine is an engine developed by General Motors of the United States, equipped with models such as Kaiyue, Xinyinglang, Baojun 730, classic Cruze, Wuling Rongguang, etc.
