The Volkswagen 1.4TSI engine will be equipped with variable cylinder technology.

Variable cylinder technology is not a rare technology. It is available in Mercedes-Benz, Honda, Chrysler and other companies, but it is mostly used in large displacement engines. A few days ago, Volkswagen introduced variable cylinder technology for 1.4TSI four-cylinder engine. At low speed, the engine will close two cylinders and only use two cylinders to work, which greatly improves fuel economy.

Volkswagen's technology is the first variable cylinder technology that should be applied to 4-cylinder engines. When goods or demand decrease, this technology will close two cylinders. Combined with start-stop technology, the fuel consumption can be reduced by 0.6 liter/100 km.

The cylinder passivation time 1400 turns to 4000 turns, and the torque is 25-75 Nm, which is suitable for low vehicle speed. If you cruise at 50 km/h and the gear is in the third or fourth gear, you can save 65,438+0 liters of fuel every 65,438+000 km by using this technology. In addition, the system has a learning function and can record the driver's driving habits. @20 19
