The role of the turbocharger
1. Combined turbocharger
The combined turbocharger is mainly composed of two supercharging methods: intake inertia supercharging and exhaust gas turbocharging.
combined. In this kind of supercharging system composition, in addition to exhaust gas turbocharging, there is also intake inertia.
The booster system is mainly composed of resonance tubes, pressure stabilizers, resonance chambers and other equipment.
The effect of the value can further increase the intake pressure after supercharging. This system can speed up the diesel engine
The operation performance of the diesel engine is improved, and it is beneficial to improve the low-speed torque operation performance of the diesel engine.
2. Exhaust turbocharger
The exhaust gas turbocharger transfers the energy produced by the engine to the turbine and expands it.
Most of the power of the exhaust gas turbocharger is used in the coaxial rotary compressor and drive of the turbine.
In the machine, the fresh air is compressed by the compressor and sent to the cylinder. Compressor and waste
The gas turbine is usually installed in one piece and is collectively referred to as an exhaust gas turbocharger. exhaust gas turbocharger
The structure is relatively simple and the working efficiency is reliable. After the scientific installation of the exhaust gas turbocharger, the diesel engine can
It can increase the power by nearly 20%~50%, reduce the fuel consumption ratio by about 5%, and help improve the overall economy
energy, emission quality and overall dynamic performance, so that it can be widely used in automobile manufacturers.
3. Compound exhaust turbocharger
Combining the exhaust gas turbocharger and its power turbine with each other constitutes the exhaust gas turbocharging job
The system is generally referred to as a compound exhaust gas turbocharger. Equipment with a high degree of diesel engine supercharging,
In addition to driving the low-pressure waste turbine to work, the remaining energy can still drive the
The exhaust gas power turbine performs the turbine processing work. This kind of power turbine is connected to the hydraulic coupling,
The compound exhaust turbocharger gear transmission works with the engine output. In this way, exhaust gas turbocharging can achieve its high-efficiency goal of continuous supercharging, and directly act on exhaust power as exhaust energy into power transmission.
Give the crankshaft a specific job. The compound turbo can also pass the exhaust gas, actually
At present, the economic performance and power performance goals are improved, but the composite exhaust gas turbocharger structure is more complex.the technology is difficult and the cost is high.
