Do you know the in-cylinder direct injection technology?It's a tall technology that makes the engine more powerful and efficient. Let me give you a science popularization, what are the advantages of direct injection technology in the cylinder!
Direct injection technology allows fuel to be injected into the combustion chamber more precisely. As a result, the fuel is better able to mix with the air for more adequate combustion. This not only improves fuel efficiency, but also reduces exhaust emissions and makes our cars more environmentally friendly.
Direct injection technology also increases engine power and torque. Because fuel is injected into the combustion chamber more precisely, the engine can work more efficiently and generate more power. This means that your car will have better acceleration and a higher top speed, allowing you to drive on the road with all your might.
In addition, the direct injection technology reduces engine noise and vibration. Because fuel is injected into the combustion chamber more precisely, the engine operates more smoothly, reducing vibration and noise. This not only improves driving comfort, but also reduces wear and tear on vehicle components and extends the service life of the vehicle.
According to the above, direct injection technology is a very advanced technology that can make engines more efficient, powerful, environmentally friendly, quiet and reliable. Although it may cost more than traditional jetting technology, its advantages are clear. If you're thinking about buying a new car, choose a model with direct in-cylinder injection technology to complete your driving experience!
Taking Volkswagen's TSI technology as an example, TSI is a unique engine technology of the Volkswagen brand, T stands for double supercharging, S stands for stratified combustion, and I stands for in-cylinder direct injection. This technology uses two different combustion modes, homogeneous combustion and layered combustion mode.
The homogeneous combustion mode refers to the injection of fuel into the combustion chamber at the later stage of the intake stroke, the full mixing with the air is completed in the intake stroke and the compression stroke, and a relatively uniform mixture is formed in the cylinder at the ignition time to ensure stable ignition. The layered combustion mode is to inject fuel in the compression stroke, and as the compression stroke progresses, the fuel is mixed with air until the ignition time is from the spark plug to the cylinder wall, and the fuel concentration is from concentrated to dilute, ensuring effective ignition and normal flame propagation, thereby improving fuel economy.
In addition, there are modern GDI technology, GM SIDI technology, Mazda DISI technology, Ford GTDI technology, etc., the difference between them is that some technologies focus on stratified combustion, some technologies focus on homogeneous combustion, and some technologies focus on lean combustion.
Overall, in-cylinder direct injection technology offers benefits such as improved fuel efficiency, reduced exhaust emissions, increased engine power and torque, and reduced engine noise and vibration. Although it may cost more than traditional jetting technology, its advantages are clear.
