How to forecast seasonal import demands

Polo engine: Volkswagen Polo's engine technical analysis Volkswagen Polo is How to forecast seasonal import demandsa very popular small The sedan is widely regarded as a representative model of stable, safe and reliable driving. And one of the keys to its success is to have excellent engine technology. The engine of the Polo model adheres to Volkswagen's consistent concept of excellence and excellence, and maintains a high degree of comprehensive quality in details and overall design. Polo's engines are mainly divided into 3 types, namely 1.0 L MPI, 1.5 L TSI and 2.0 L TDI. Among them, the biggest innovation is the 1.5 L TSI extreme version engine. This model of engine is equipped with manual gear or 7-speed dual-clutch transmission DSG, which can accelerate to 0-100 km/h in 7.9 seconds. Various engine models are located behind the front-wheel drive shaft, and a number of technologies have been developed with this concept to provide vehicles with a wider speed range and higher efficiency. The following will be a detailed analysis of each engine one by one. The 1.0 L MPI1.0 L MPI engine is an entry-level engine used by Volkswagen in Polo models. The engine adopts 3 cylinders, 4 pistons in each cylinder, and 12 valves.Layout, and can produce a maximum power of 55 kW (75 PS) / 6,200 rpm and a maximum torque of 95 Nm / 3,000 rpm. In terms of fuel system, the 1.0 L MPI engine uses a multi-point fuel injection system to improve fuel efficiency. This is a management system that controls the accurate amount of fuel required for each cylinder according to the load and speed of the engine. The system monitors the engine speed, oxygen sensors, cooling water and intake temperature sensors in order to obtain the correct cylinder load state and improve fuel economy and reduce emissions. 1.5 L TSI 1.5 L TSI is a very good engine launched by Volkswagen in the Polo model. This engine adopts 4The design of a cylinder, 4 pistons per cylinder, 16 valves, and equipped with a Turbocharger and a Direct Injection system. The combination of these technologies provides incredible power and responsiveness to the engine, generating a maximum power of 110 kW (150 PS) / 5,000-6,000 rpm and a maximum torque of 250 N? At the same time as m / 1,500-3,500 rpm, the acceleration time can reach 100 km/h in only 7.9 seconds. In terms of fuel management, the 1.5 L TSI engine adopts Direct Injection technology.This efficient design enables fuel to be injected into the combustion chamber more accurately, thus increasing the efficiency and fuel economy of the engine, while reducing emissions. In addition, the 1.5 L TSI engine is also equipped with an Active Cylinder Management system, which can turn off two cylinders under low load to save fuel, which is also an important reason for the further improvement of the fuel economy of this engine. 2.0 L TDI 2.0 L TDI engine has long been widely regarded as a high-quality, environmentally friendly and highly efficient diesel engine. It has 4 cylinders, 4 pistons per cylinder, 16 valves, maximum power 85 kW (115 PS) / 4,000 rpm and maximum torque 250 N?M / 1,500-3,000 turns/minute. The engine adopts Direct Injection technology and Turbocharger to give full play to the advantages of diesel fuel, thus providing more power and torque for the vehicle. The 2.0 L TDI engine also has a very high fuel economy. It is equipped with BlueMotion Technology, including a series of fuel economy improvement technologies such as throttle closure, low rolling resistance wheels, and emission control standards. In practice, this engine provides very good fuel economy and environmental protection performance, which can significantly save fuel consumption and emissions. In summary, the engine of the Volkswagen Polo model left a very deep impression on people.These engines all adopt advanced technology and have a high speed range and efficiency. In general, they can achieve a proper balance between comprehensive performance, power, torque and fuel economy. Each engine has made an important contribution to the success of the Polo model and has become one of the key factors loved by many car fans.
