The Volkswagen EA211 series engine is the most important component of the Volkswagen MQB platform. The commonly used EA211 engine now mainly refers to the 15L self-priming engine and the 14T turbocharged engine. Many people should have questions about the Volkswagen 14T engine. And which 15L self-priming engine is of better quality?More reliable durability?
14T engine, compared to the first 14T engine in the EA111 series, the EA211 platform engine adopts a modular design, while further improving performance, reducing fuel consumption, and adopting lighter, anti-friction technology. According to information released by Volkswagen, the EA111 has a fuel consumption ratio reduced by about 8%. The main technologies of the EA21114T engine are as follows:
Modular design of MQB platform. Based on the requirements of the Volkswagen MQB platform for modular engine mounting positions. The EA211 has the same intake and exhaust orientation as the EA888, changing the intake and exhaust from the original front and rear rows to the front and rear rows. The mounting angle and attitude of the engine have also been adjusted.
Aluminum cylinder design. The first-generation EA111 used an iron cylinder block, while Volkswagen used an aluminum cylinder block in the design of the EA211, mainly to reduce weight. The weight of the block is 16 kg lighter than that of the cast iron block of the EA111. From the point of view of reliability and durability, I think iron cylinders are more advantageous, but aluminum cylinder technology is also mature now.
There are no negative reviews about the EA211's aluminum barrels yet. This change should be based on reliability and weight. The reduction was still successful. Although the 14T engine is structurally more complex than the 15L engine. Not only is it simple to have one more turbine, but the requirements for individual components and control systems are also higher. The mechanical structure is indeed simpler and theoretically more reliable.
But quality depends on overall performance. If the turbocharged engine is fault-free in all respects and the details are well handled, then its quality performance will be just as reliable, as is the case with the 14-ton engine. Maybe someone will talk about oil. It's burning now. In fact, it is the first in the EA888 series.
In addition, the third-generation EA888 has improved fuel consumption, which is now less likely to happen. The same principle applies to other brands, such as Toyota's 16L and 12T. At the beginning, it was said that 12T is not as mature, stable and reliable as 16L, but this is only theoretical.
But the 12t engine is in practical application, there are no problems in the process, 92 octane gasoline can be added, and maintenance is not expensive. Turbocharged engines have higher pressure in the cylinders and higher temperatures. While the structure and materials of the turbocharged cylinders are strengthened, the various rubber parts and sealants of the engine harden and become brittle at high temperatures.
This, in turn, leads to turbocharger leaks. The high temperature in the turbocharged cylinder, especially the high temperature of parts such as the piston ring, will cause the oil to sinter into the piston ring more easily when the piston ring is rubbed, blocking the oil return hole. Causes oil to burn. This is also the main reason why many turbocharged engines are prone to burning oil. Volkswagen 14t turbocharged engine!
The exhaust gases produced after the engine runs pass through the turbine, which starts compressing the air and sends it to the cylinders. At this time, the gasoline burns with a very good amount of air, so the power is strong, and when the engine speed reaches 1500 rpm, the turbo begins to intervene: the supercharging begins to increase!
The engine has the advantages of low fuel consumption, high power and small displacement!When the turbocharged engine is running, it is in a high temperature state for a long time, which has a great impact on the life of the engine. Also, after refueling, there is a certain delay in power supply!Turbocharged engines also have higher oil requirements than naturally aspirated engines. Try using a fully synthetic motor oil and adding 95 gasoline, while a naturally aspirated engine requires 92
Turbocharged engines are more expensive to repair and will have more problems in the future!All in all, if you have certain requirements for the power of the car, and the road driving conditions are relatively smooth, then you can still choose 14t. However, if you often drive in congested conditions, then the dry dual-clutch should be purchased with caution.
