It is more troublesome to remove the hot water tank in Passat because the front heating ventilation duct and instrument panel are blocked, so for convenience, it is necessary to remove the instrument first and then the hot water tank. The cooling water of the engine is used as the working fluid, and under the action of the blower, it is blown into the cabin from the same air outlet to achieve the purposes of heating, ventilation, and defrosting. There are two main ways of air intake: one is indoor air circulation, and the other is outdoor fresh air entering the room for ventilation circulation. The blower is driven by electricity and is also affected by the engine speed. Even when the engine speed is very low, it can still perform heating and defrosting functions. The water temperature in the water tank is always maintained at a high temperature, so that the hydrocarbon groups in the water can combine with calcium and magnesium plasma to form water-insoluble calcium carbonate and magnesium carbonate, commonly known as water alkali. Then, as the water continues to evaporate and concentrate, the alkali content of the water continues to increase and reaches saturation, forming scale. Therefore, adding pure water containing high concentrations of calcium and magnesium ions will form scale more easily than adding ordinary tap water, so adding this kind of pure water to the water tank has no effect on inhibiting the formation of scale in the water tank. The water tank plays a role in heat dissipation under normal working conditions, but once scale forms around the water tank, it will greatly affect the heat dissipation of the water tank. Since the thermal conductivity of oxide scale is very low, only 1/25 of cast iron and 1/50 of brass, the oxide scale formed in the cylinder liner and cylinder head water passages will increase the temperature in local areas due to poor heat dissipation, which will lead to engine weakness. Cracks occur in the parts, causing the cylinder head to deform. It not only worsens the heat dissipation performance of the cooling system, but also creates local high temperature areas, worsens lubrication conditions, increases engine temperature, and accelerates wear and tear of the engine system. It also blocks the heat dissipation pipe or cooling system pipe, greatly reducing the heat transfer efficiency, causing the engine to overheat, directly endangering the driver's safety.
What is the fuel consumption of the Passat Lingyu 2.0? What is the fuel consumption of the new Lingyu 2.0?
According to the comprehensive fuel consumption of the Ministry of Industry and Information Technology, the new Passat leader has a comprehensive fuel consumption of 8.5L/100km. However, according to actual measurement data of some new Passat leaders, its fuel consumption is generally around 10L/100km, which will vary depending on the driver's driving conditions and road conditions. As of August 2019, the new Passat Yuling has been completely discontinued. The latest new Yuling is from 2011, and the current price on the secondary market is between 35,000 yuan and 95,000 yuan. Passat's new Yuling has two power versions to choose from, namely the 1.8-liter turbocharged version and the 2.0-liter naturally aspirated version. Among them, the 1.8-liter turbocharged version has a maximum horsepower of 163 horsepower, a maximum power of 120kw, and a maximum torque of 220N·m. The 2.0-liter naturally aspirated version has a maximum horsepower of 116 horsepower, a maximum power of 85kW, and a maximum torque of 172N·m. In terms of fuel consumption, the 1.8-liter turbocharged version has a maximum horsepower of 116 horsepower, a maximum power of 85kw, and a maximum torque of 172N·m. The Ministry of Industry and Information Technology's comprehensive fuel consumption is 9.1L/100km, while the 2.0-liter naturally aspirated version is 8.5L/100km. In terms of gearbox, the new leader of Passat has 5-speed manual and 5-speed manual integrated to choose from. In terms of suspension, the front suspension of the new Passat leader is a multi-link independent suspension, and the rear suspension is a composite torsion beam non-independent suspension.
