Supercharged engine is very traditional to enhance power and fuel economy measures, universal T25 turbocharger but it can also reduce harmful engine emissions, with the continuous development of new technologies supercharger technology has been steadily progressing. Conventional turbocharged and supercharged there are no satisfactory place to put the two technologies together regarded as a workaround.
Today in the car with the engine turbocharger depending on the structure can be divided into two categories - mechanical supercharger and turbocharger. Early belong supercharged supercharger, known as the "super booster" (Supercharger), and later invented the turbocharger, it is called a Turbocharger.
Like air compressor supercharger
Like a mechanical supercharger engine accessories like power steering pump mounted on the engine by engine belt drive, the compressed air supplied to the intake manifold. Mechanical supercharger simple structure, T25 turbocharger temperature between 70 ℃ -100 ℃, no special cooling system, mechanical maintenance. However, with the increase would boost the value of the engine speed decreases when it reaches a certain threshold, because of their resistance to the turbocharger it will become a burden on the engine, the engine speed to enhance seriously affected.
Therefore, the current European production of mechanical supercharging system mostly take low-pressurized. The advantage is that the rotor speed corresponding to the engine speed is no lag smoother power output, and low cost. The disadvantage is to consume engine power, mechanical supercharger prone to noise.
Like Mercedes-Benz's small-displacement gasoline engines on the use of a mechanical supercharger. SLK two supercharged four-cylinder engine output of 120kW and 145kW, emphasized the low speed high torque, SLK 200KOMPRESSOR reached when 2500rpm and maximum torque 230Nm, combined fuel consumption of just 8.8L / 100km, 4-cylinder engine with the fuel characteristics to achieve six-cylinder torque characteristics of the engine. This mechanical supercharger is Mercedes and Eaton Corporation jointly developed, the performance is very good, the turbocharger maximum speed reaches 14000rpm.Learn More
