In recent years, the boom of turbocharged engines has continued to rise, and even many brands that once took the lead in naturally aspirating have also transformed turbocharged engines. Especially for some young people who have just bought a car, the power boost from turbocharger is undoubtedly the temptation to give up. The "T" logo everywhere seems to convey a message to people: The turbulent era has become unstoppable. Admittedly, turbocharged engines have many advantages, but in the course of daily use, they will also increase our car costs. Here we will talk about the advantages and disadvantages of turbocharged engines and maintenance.
Looking at the entire automotive market, turbocharging is becoming more and more a trend, and our today’s protagonist, Beijing Auto Co., is also equipped with three turbocharged engines, including 1.8T, 2.0T, and 2.3T.
Beiqi Shenbao is designed based on the Saab 9-5 GM2900 platform, but it has been lengthened according to the characteristics of Chinese consumers. It has been lengthened from the 2703mm wheelbase to 2755mm, and the vehicle size has reached 4861mm×1820mm×1462mm.
Why choose a turbocharged engine?
The turbocharger is actually an air compressor that increases the air intake of the engine by compressing the air. The most direct benefits it brings are undoubtedly the improvement of power. Under the premise of equal displacement, turbocharged engines can be nearly 40% higher than naturally aspirated engines. Taking this test drive as an example, the Sic Bo equipped with a 2.3T engine has a maximum power of 184kw, which is close to the 3.0L naturally aspirated model.
With the same displacement, turbocharged engines have higher combustion efficiency and more power. In daily use, when the turbine is directly involved in the vehicle, it is faster acceleration, which is what we call everyday, which brings a more enjoyable driving experience.
In addition, with the introduction of favorable policies for small-displacement vehicles, such as energy-saving emission reduction, the advantages of small-capacity, high-power turbocharged engines have been fully utilized in many new models. Of course, this does not affect the owner's car cost too much, but it can be a major factor in the selection of turbocharged engines by major manufacturers.
â– What are the drawbacks of turbocharged engines?
For the owner, the biggest drawback of turbocharged engines is high maintenance costs. Because the turbocharged engine requires high oil lubrication and cooling effects, it generally requires the use of fully synthetic motor oil for maintenance, which increases maintenance costs.
In addition, the turbocharger has a higher requirement on the strength of the engine block, and the maturity of the technology does not reach the level of a naturally aspirated engine, so the failure rate will be improved. Because turbocharging will bring higher combustion temperatures to the engine, theoretically, turbocharged engines have a shorter life span, which results in higher maintenance costs.
In terms of daily driving, although turbocharged engines can provide powerful power, the obvious feature in most models is the existence of turbo lag. Of course, for some high-end luxury models, the sense of lag is not significant.
However, for a general price model, the intervention time of the turbine may not be satisfactory. This requires a friend who has intention to buy a car to make a decision after the test drive. Take Beiqi Saibao as an example, the 2.3T engine has no obvious lag in actual driving and the dynamic response is relatively positive. The model at this level is already a quality product, let me see the successful application of the own brand in turbine technology.
In general, the advantages and disadvantages of turbocharged engines are quite clear. From my personal point of view, I prefer the driving pleasure it brings. But the cost of maintenance is also a problem that owners can't ignore. Here we take a look at the maintenance of turbocharged engines.
The maintenance and maintenance costs of turbocharged engines have always been its major drawback. This is not a factor that owners can decide, but we can protect the engine effectively by daily protection of the vehicle and thus save costs. .
â– Selection of engine oil and fuel
In general, the damage of the turbocharger is usually caused by the damage of the seal between the turbocharger and the intake pipe, resulting in large-scale burning of oil. The damage of the seal is caused in large part by the owner's failure to replace the oil on time, or the use of inferior oil. Causes the floating turbine's main rotating shaft to not be properly lubricated and dissipated, thereby damaging the oil seal and causing oil leakage at high temperatures.
Therefore, this requires the owner to replace the engine oil in time, and insists on choosing a fully synthetic engine oil with better oil to meet the normal operation of the engine. Special attention should be paid to the fact that high-end lubricating oils are indeed better than low-end lubricating oils in terms of their anti-oxidation and anti-emulsification capabilities, but they should not prolong the replacement cycle too much, otherwise they will not be able to exert the effects of high-quality oils.
At the same time, the requirements for fuel quality of turbocharged engines are also relatively high. Beiqi Shenbao is clearly marked at the fuel cap and the car is suitable for No. 95 (former No. 97) gasoline.
â– Keep the turbine clean
The cleaning of the turbine mainly depends on the air filter element and the oil filter element. The timely replacement of the two components can effectively avoid excessive wear of the turbocharger due to absorption of the magazine, thereby increasing the life of the turbine and allowing the vehicle to run more stably.
The turbine looks a bit "squeamish." Perhaps many owners have already begun to worry about whether their vehicles are in a normal state. The turbocharger equipped on the dashboard of the BAIC can clearly and clearly show the working status and real-time values ​​of the turbine. intimate.
â– Cold start and flameout
First of all, we need to make sure that the turbine is a high-speed component and that it needs real-time protection of the oil. Therefore, we recommend that the owner go on the road after a short hot car at cold start. This can effectively ensure the full supply of oil, especially for the north. The owner of the car, the correct hot car is more important.
When the engine stops and the flame is turned off, the temperature of the turbine is very high. Therefore, it is better for the owner to stop the car at idle speed for a while. At idle, the oil and the cooling system are all working, which can effectively reduce the temperature of the turbine and provide protection.
PCB substrate materials mainly include ceramic
substrates, resin substrates, and metal or metal matrix composite materials.
Compared with metal and resin substrates, ceramic substrates have outstanding
electrical insulation properties, excellent high-frequency characteristics, and
better Excellent thermal conductivity, thermal expansion rate, compatibility
with various electronic components, stable chemical properties, etc., are more
and more widely used in the field of substrates. Ceramic substrate products are
divided into Bare Ceramic Substrate and Metallized Ceramic Substrate according
to the production process. They are widely used as substrate materials for
different thick films, thin films, and circuits. They can also be used as
insulators, as heat conduction paths and in circuits with demanding thermal
performance. Used to manufacture various electronic components.
We have been producing a variety of advanced ceramic substrates for many years and have extensive manufacturing experience in Al2O3, AlN and Si3N4 materials.If customers have high precision requirements or edge processing requirements for substrate products, we can meet various requirements for size, thickness, shape and surface finish through fine grinding, polishing, laser scribing, and laser cutting processes.
