Turbocharged engine maintenance need to pay attention to what?

2018-03-25 17:36:11

Looking back in the past, the invention of turbocharging technology has more than 100 years of history, from the initial Swiss patent technology application; To Porsche, BMW in the European car market first application; Today, turbocharging technology has become a development trend. It is not only the patent of high-end luxury cars, but is widely applied to the current mainstream engines, such as 1.6T and 2.0T engines. As the European Union begins to significantly tighten emissions standards, with a particular emphasis on carbon emissions, the use of turbocharging technology can essentially preserve the original peak power output while the engine is miniaturized. At the same time, carbon emissions could easily fall thanks to lower emissions. Turbocharging technology is not only used in daily driving, the world's top motorsport F1 Formula car since 2014, more and more attention to engine reliability and fuel efficiency, F1 engine from the original 2.4L V8 to 1.6L V6, which means that the engine size is reduced, but still need to produce 600 horsepower such a powerful power. Therefore, the harsher working environment of the engine will exacerbate the overheating of the key components inside the engine, and the challenge is that the cooling system can not reach the key components of the engine. Petronas, which has helped Mercedes-AMG-Petronas F1 team win the Team of the Year championship for three consecutive years, and its engineers have applied F1 technology to the field of civilian vehicles, developing Petronas brilliant lubricants containing unique ℃oolTech™ Kutai ™ technology, which can absorb and remove excess heat deep in the engine. Prevent the wear and performance degradation of key engine components caused by local overheating, and prevent the damage caused by local overheating of the engine from the root. In the field of civilian vehicles, turbocharged engines also achieve small displacement of high power output, so more and more gasoline engines began to be equipped with turbocharged technology, Turbo has gradually become synonymous with civilian high performance. Combined with a small displacement engine, it provides good power performance and low fuel consumption, thus becoming synonymous with energy efficiency. So what special attention should be paid to the maintenance of turbocharged engines?


Turbocharged technology models of oil consumption and lubrication requirements are particularly high, it is recommended that we should replace the lubricating oil within the specified maintenance mileage, and try to choose the original recommended oil, such as Mercedes-Benz AMG model of the initial installation of oil is Petro Malaysia Xuanting 7000 full synthetic lubricant. The biggest feature of turbine engine is high power and low fuel consumption. This relies on its precise design and manufacturing process, but also determines its harsh working environment. The harsher working environment of the engine will exacerbate the overheating of the key components inside the engine. The challenge is that the cooling system cannot penetrate into the key components of the engine. The Petro Oil series containing ℃oolTech™ Cooltech ™ technology strengthens the molecular chain of the oil film, absorbs and carries away excess heat deep inside the engine, effectively controls the accumulation of deposits caused by high temperatures, prevents oil oxidation, and prevents local overheating that can cause wear and performance degradation of the key components of the engine.


Slow start slow acceleration turbocharged engine models after starting, do not step on the accelerator, should first idle for 3 to 5 minutes, so that the oil pump has enough time to transport the oil to the various parts of the turbocharger, after the oil temperature slowly rises, the turbocharger will be fully lubricated, at this time the speed will be like a fish in water. This is especially important in winter.


The habitual inspection of the supercharger before the car, after the car, should check the connection of the airway, to prevent loosening, falling off and causing the failure of the supercharger and air short circuit into the cylinder. When it is found that the oil suddenly becomes dirty, and the crankcase pressure rises rapidly, the excessive consumption of oil and other phenomena, it is necessary to check whether the seal ring of the turbocharger is invalid. Because if the seal ring is not sealed, then the exhaust gas will enter the engine lubrication system through the seal ring, the oil will become dirty, and the crankcase pressure will rise rapidly, resulting in excessive oil consumption and "burning oil" situation.
