Cars should be carefully loaded turbocharged



Before and after the Spring Festival, a number of car-repair Harbin played for car modification turbocharger ads, some car owners will also be included to enhance the power of the spending plan. To remind the industry,Ford Turbo automobiles should be carefully modified turbocharger and prevent improper modification shorten engine life.
"My car is a 1.6L displacement, the foot pedal down feel boring, I heard that now give car-repair car loaded turbocharged, I also want to allow the car to install a 'red' up." Private to enhance the car owners to national power, specifically to find a car-repair Harbin modified turbo unit, but was told that modification may have a greater harm to an automobile engine, to enhance the role of the vehicle power is not obvious.
According to the professional division LIU Kui car modification introduced, automotive turbocharger technology is actually increasing the use of intake air into the combustion chamber, the combustion is more complete, higher operating efficiency of the engine. "While that sounds simple, in fact, is a very complex process, but without careful consideration on modified turbo, will greatly shorten engine life."
For supercharged engine modification, much more than you can install a turbine,Universal Turbo along with the corresponding parts have to be replaced. Turbocharged engine inside than the naturally aspirated engine is generally more pressure, so many parts and seals require special. Now the car basically EFI car, so even with sophisticated electronic control systems do match, but the most difficult to achieve technical standards repair lines.
In addition, the engine compression ratio is too high or the original general automobile manufacturing process, as well as some at the factory has done a good automatic car vehicle performance to match, are likely to bear the huge torque from the engine is not suitable for conversion turbine boosting device.

Turbo engine maintenance tips


Not a car left
After the engine is started, especially in the winter, should be allowed to idle for a period of time in order before the turbocharger rotor at high speed so that the lubricating oil to fully lubricate the bearings. So, do not start just after Meng throttle to prevent damage to the turbocharger oil seal.
Can not turn off immediately
After the high-speed operation of the engine for a long time, should be idle for 3-5 minutes and then turn off. When the engine is working, there is a part of the oil supply turbocharger rotor bearing lubrication and for cooling. Ford 1.6 turbo After running the engine suddenly shut down, oil pressure rapidly falls to zero, the high temperature reached turbocharger parts of the middle of the heat bearing shell can not be quickly taken away, while the high-speed rotation inertia of the turbocharger rotor is still at the same time Therefore, the engine is suddenly stopped, if the status of the heat engine, it will cause the retention of the turbocharger oil overheating and damage to the bearings and shafts. Particularly to prevent the throttle suddenly turn off after Meng kicks.
Keep clean
Time to clean the air filter to prevent dust and other contaminants from entering the high-speed rotation of the compressor impeller, resulting in increased speed instability or wear bushings and seals. Citroen 1.6 turbo Engine oil and filter must be kept clean to prevent contaminants from entering, otherwise oil lubrication capacity decreased, resulting in premature turbocharger scrapped.
When removing the turbocharger, to keep clean, all fittings must use a clean cloth to plug well, to prevent debris from falling into the turbocharger rotor damage. Since the turbocharger often operate at a high temperature, Mini 1.6 turbo its oil pipelines due to high temperature, internal oil prone parts of coke, this will cause insufficient lubrication of the turbocharger bearing damage. Therefore, the lubricating oil pipeline after running for some time to be cleaned.

Turbo coming era of universal


Recently, the Ministry of Industry and Information Technology of the "industrial energy" second five "plan." To 2015, the internal combustion engine fuel consumption goods decreased by 10% over 2010, to market energy-efficient internal combustion engine products accounted for 20% of market holdings.

Currently, many manufacturers have been using turbo technology.exhaust manifold manufacturer Volkswagen was the first to market small-displacement turbocharged engine of the car companies, TSIDSG combination sought after by the market of its launch, the product has been in short supply. BYD, Great Wall, Brilliance, SAIC, Chery and other brands have also introduced a turbocharged engine, Chery is developing a 0.8T turbocharged engine. General Motors is developing a 3.6L twin-turbo engine, and even has always insisted naturally aspirated engine of the BMW brand, is also developing twin-turbo engine.
Turbocharged engines rely on the turbocharger to increase the intake air amount of the engine, thereby increasing engine power output. Its biggest advantage is not to increase emissions, significantly increasing engine power and torque, improve fuel economy and reduce emissions. Data show that the use of turbocharging technology can help gasoline and diesel vehicles in fuel economy without compromising performance up to 20% and 40%, respectively. At the same time, compared to hybrid vehicles and electric vehicles, but also to achieve substantial cost savings.
A few years ago, the state introduced a number of policies, 拨放 large sums of money to encourage the development of electric cars, but few market sales. Later, the national adjustment policies on energy efficient cars and new energy vehicles equal importance, as long as help to reduce fuel consumption and emissions, will receive a variety of techniques to allow and encourage. 863 Plan "energy saving and new energy vehicles," Wang Binggang major science and technology projects Distinguished experts have said the country will focus on four areas of technology development, one of which is an advanced powertrain and vehicle technologies, such as advanced engine and gearbox . Small-displacement turbocharged engine in achieving energy efficiency while reducing emissions and fuel consumption, is undoubtedly the most to meet the requirements.
Some foreign company expects the global turbocharged engine market will achieve sales double in the next five years. 2009, turbocharged engines totaling 17 million units sold worldwide, in 2015, this figure will reach 35 million units. By 2015, the market share of China's turbocharged engine from the current nearly 10% to 20%.

Geely engine



Compared to the first few independent manufacturers, Geely Group's existing brands and models, but also do not have a turbocharged engine in use, but at a show, they look to come up with two different displacement turbo compression engine, clio dci turbo which appeared two engines also allows us to become more promise Geely expectations.
● 1.3T engine code JLβ-4G13TD
Power system using small-displacement turbocharged engine is a trend compact and small cars, Geely Group's models, such a crucial technical reserves.

On the technical characteristics, direct injection technology be the best partner turbo technology, this 1.3 liters engine also uses this technology portfolio mainstream nowadays, in other hardware, based on the dual variable intake and exhaust timing technology also created favorable conditions for the work efficiency of the engine.
By comparing the data, Geely this 1.3T engine at maximum power and maximum torque data are higher than the public's EA111 1.4T engine, however, such a radical adjustment in volume production in the future will be able to come up with much skill when it?
● 1.8T engine code JLE-4G18TD
Geely Group's current product deployment perspective, Geely Global Hawk GX7 models with this larger displacement 1.8-liter turbocharged engine compare match, if able to existing 2.0-liter naturally aspirated engine to be replaced, kubistar turbo then, in the own-brand compact SUV models in the camp, and its dynamic performance is bound to lead to other competing products models.

This engine's maximum power of 184 hp and maximum torque of 285 N • m. Technical structure of this engine is the same basic described above 1.3T engine, fuel system uses direct injection technology, the contribution of the two technologies for power and fuel economy has been a common theme, in addition, dual variable timing technology Among the many display engine seems to have a standard configuration, almera turbo of course, with hardware support, a suitable adjustment also determines the key to whether the engine performance and effective play.
To sum up:
In the current situation, Geely Group is still in the future will focus on the product compact car, the emergence of these two engines basically meet the next few years the brand's product deployment, where smaller displacement 1.3T engine used in its compact car, mini-car products, while existing models such as the compact SUV can facelift 1.8T engine, it is bound to increase vehicle products in the market competitiveness.

More exciting video, all in car home video channel


This 3.6-liter V6 twin turbocharged engine supercharging system is different from the traditional structure, central though not as Audi, BMW turbo exhaust system that will be placed with a V-type engine intake pipe length (shorter booster after improving engine response speed), eliminating the conventional air-cooled in the intercooler, the overall structure is more compact,passat 1.8 turbo more importantly, such a structure can also achieve the effect of shortening the length of the intake pipe.

In addition to the intercooler integrated in the intake manifold, this engine also uses harmonic intake. Designers use a certain length and diameter of the intake manifold and the resonance chambers resonance intake system, and make it the natural frequency coordination with the valve opening period. In particular rotational speed, until the intake valve is closed, is generated in the intake manifold pressure wave significantly, the intake manifold pressure increases, thereby increasing the intake air amount.

Engine exhaust valve of the valve is also applied, sodium filling technique that the design of the valve stem is a hollow structure, and then charged into one of the metallic sodium. Under normal engine operating temperature,vw passat turbo liquid metal sodium in the valve will be opened and closed with the upward and downward movement. Due to a large specific heat capacity of sodium, so it can well absorb heat from the valve head and conduction, which reduces the valve temperature in harsh working environments.
To sum up:
Structurally, this engine is very Aspect, installed in the intake manifold of the water-cooled intercooler replaces the traditional air-cooled water cooler, so that more precise control, while the structure is also more streamlined,audi a4 turbocharger this way on a large displacement engine is the first time I saw. As for performance, it is left to the future have the opportunity to experience it. Now, there is no reason not to expect a new generation of Cadillac CTS, of course, especially equipped with 3.6 l V6 turbocharged engine performance version.

BMW will disable 1.6T engine is expected to involve a series of MINI


BMW recently announced that respect: In cooperation with PSA Peugeot Citroen engine project or will end in 2016, after the use of self-developed modular engine. At present, jointly developed by BMW and PSA Peugeot Citroen engines are mainly used BMW 1 Series and MINI models, so the future BMW models will be more fully stop using 1.6T engine.

In recent years, Volkswagen MQB platform for representatives from car manufacturers are turning as previously modular platform, while BMW will also be modular plan as the next major development goals. BMW previously announced that it will produce a respect 1.5L three-cylinder turbocharged engine, the future will mainly carry on "UKL" platform, Peugeot Turbo and a small car platform, this platform for future precursor MINI and BMW 1 Series is commonly used. The combination of BMW recently announced the end of the engine on the 2016 collaboration news, BMW and PSA Peugeot Citroen's cooperation is gradually coming to an end, so far 1.4 / 1.6T engine BMW and PSA co-production is about 1 million units, most of are equipped to the MINI and a department.

BMW and PSA Peugeot Citroen had jointly developed the production of four-cylinder engine named Prince, called the BMW internal model N14, displacement areas were 1.4L, 1.6L and 1.6T versions. The engine used in 2007 MINI models equipped with MINI was replaced before the Trutec engine, in addition to this engine was also used in the Peugeot 207 models. Mazda Turbo The next MINI and BMW 1 Series will be equipped with 1.5T turbocharged engine developed to replace the now jointly developed with PSA Group 1.6T turbocharged engine.

BMW's MINI brand models currently used in 1.6L and 1.6T engine was jointly developed with PSA engine, while the previous two years, there were aspects of a product called MINI MINI ONE models, matching the 1.4L engine, but models have been discontinued in the two years since then has not been introduced models equipped with 1.4L engine. Thus we can analyze, Ford Turbo MINI future trends will be fully dilute cooperation with PSA 1.4,1.6 engine in favor of BMW "modular" 1.5 engine.

Self-developed 1.5-liter BMW TwinPower turbocharged three-cylinder engine, the use of the now popular variable load control, direct fuel injection and variable valve control and other advanced technology to its vehicle fuel economy, emissions performance has been greatly improved . In addition, from the top of the table comparison, we can see that the BMW three-cylinder engine developed by 1.5T, the maximum power of 149 kW and peak torque of 268 Nm from the cash value has been completely beyond the 1.6T engine performance.
With the continuous progress of the competition and rapidly changing market situation, a lot of promising technologies originally had to face a similar demise, which is the law of the market's performance, and now the BMW 1 Series and MINI 1.6T currently being used will also face The same situation, which can not help but feel pity. But we should expect BMW developed its own 1.5T engine, because this engine will be used in the future BMW models will be the first ever from the precursor model platform's first front-drive platform.
