Both are engine forced intake devices. The core difference lies in the driving method: mechanical supercharging is driven directly by the engine, while turbocharging is driven by exhaust gas. In terms of driving experience, mechanical supercharging is similar to naturally aspirated engines, with quick response and suitable for scenarios that emphasize smooth operation and low-speed power; turbocharging excels in efficiency and energy conservation, as well as strong high-speed power output, makin

The turbocharger utilizes the high-temperature exhaust gas from the engine to drive the turbine, which in turn drives the coaxial compressor to compress the intake air. It is a energy recycling device. It consumes almost no effective power of the engine, has a high boost strength, enables small-displacement engines to achieve the power of larger-displacement engines, offers better fuel economy, and is currently a mainstream configuration for family cars. However, due to the inertia of the turbin

The mechanical supercharger is driven directly by the engine crankshaft through a belt. It uses its own power to drive the compressor to compress air, thereby increasing the engine's intake volume and power. Its power output is linear and smooth, without power lag. It has sufficient torque at low speeds, and performs well in starting and low-speed acceleration. However, it consumes a portion of the engine's power. The efficiency at high rotational speeds is relatively low. The overall fu

In fact, speaking of these two supercharging technology is not new, the emergence of turbocharging technology from now has more than 100 years of history, supercharging is earlier, but these two technologies were not provided for cars, the earlier supercharging technology is mainly used for mining and ventilation and industrial boiler intake. Turbocharging is the technology used in the first World War on the aircraft, and later the two technologies slowly entered the automobile industry, with the continuous advance of modern technology, the two have been a hundred years of technology red confusion. When it comes to turbocharging, it will naturally mention natural aspiration, and then produce two gangs, a self-powder and vortex powder, the natural aspiration structure is relatively simple, and turbocharging is equipped with a set of turbochargers on the basis of natural aspiration, which is naturally stronger than self-aspiration in terms of power

1. Marine supercharger uses engine oil for lubrication, the oil needs to reach CD level or above, and must be filtered by full-flow filter, filter size is less than 20u. 2. Turbine supercharger must be lubricated in advance under the following circumstances: downtime is too long or winter; After lubricating oil replacement or repair (including draining lubricating oil). 3. In the engine, within 3 to 4 seconds after starting, the oil inlet of the supercharger needs to display 69+69 kpa(0.7 kgf/cm2) oil pressure. 4, when the engine is running with load, in the Z high torque condition and above, the oil pressure at the supercharger inlet should be in the range of 196-392kpa(2.11-4kgf/cm2), and not less than 69kpa (0). 7 kg force per square centimeter). 5. The inlet temperature of lubricating oil should be lower than 100℃, and the Z height should not exceed 120℃C6. Do not use liquid seals

What condition would the car be in if the turbocharger parts were broken? Let's let Xiaobian explain it to you! Turbocharger accessories blade shaft seal failure phenomenon: total speed of the exhaust gas blue smoke, light when heavy. There is no blue smoke during driving, and the oil is consumed. Second, the exhaust gas recirculation pipe serious blockage fault phenomenon: total speed and driving exhaust blue smoke, refueling is more serious, oil consumption is large. Third, the piston ring, cylinder wall, valve oil seal wear or aging fault phenomenon: the vehicle takes a lot of blue smoke, the turbocharger turbine end has an abnormal sound, the turbocharger turbine end leakage of oil four, turbocharger accessories air duct rupture fault phenomenon: the vehicle fuel door and throttle will have a "pull-up" abnormal sound.

Engineering supercharger has four main advantages :1, improve the engine power. In the case of constant engine displacement, the intake density can be increased to make the engine inject more fuel, thereby increasing the power of the engine. The engine power and torque of the construction mechanical supercharger will be increased by 20% to 30%. On the contrary, under the requirements of the same power output, the cylinder diameter of the engine can be reduced, and the volume and weight of the engine can be reduced. Improve engine emissions. By improving the combustion efficiency of the engine, the turbocharger engine reduces the emission of harmful components such as particulate matter and nitrogen oxide in the exhaust of the engine. It is an indispensable configuration for diesel engines to meet the emission standards above Euro 2, and provides platform compensation function. In some high altitude areas, the higher the altitude, the thinner the air. An engine with a turbocharger can m

Engineering supercharger is the use of engine exhaust gas to drive the turbine. No matter how advanced, it's still a mechanical device. Because it often works at high speed and high temperature, the exhaust gas turbine end temperature of the supercharger is above 600 degrees, and the speed of the supercharger is also very high. Therefore, in order to ensure the normal operation of the supercharger, it is very important to use and maintain it correctly. We should mainly follow the following methods: 1. After the car engine starts, do not step on the accelerator quickly, and the total speed should be three minutes. This is to increase the oil temperature, improve the flow performance, get the turbocharger well lubricated, and then you can increase the engine speed and start driving. This is especially important in winter, when it takes at least five minutes to warm up the car. 2. After the engine has been running at high speed for a long time, it cannot be turned off immediately. The rea

People who buy to install mechanical turbochargers should not be used on cars with turbochargers, and they can certainly be installed on naturally aspirated cars. Since natural inhalation, in the middle of the air intake pipe such a thing, it itself has no power, Z is mostly to change the small direction of the air flow, probably can be understood as the principle of air conditioning in the car to adjust the wind direction, that is, by adjusting the Angle of a set of blades to change the wind direction, it is completely impossible to "pressurize" the speed of the wind through this thing, can only more or less affect and reduce the wind speed. In the intake pipe can only play a negative role of obstruction, which is a small negative effect, but also some, at least these iron sheets reduce the cross-sectional area of the inner diameter of the intake pipe. Be careful when choosing oil. Due to the role of the turbocharger, the air quality and volume entering the combustion chamber
