What does a dual-engine car mean?

[BenjaminLynn]

Dual-engine cars are highly efficient and low-consumption vehicles equipped with two sets of engines—an electric engine and a gasoline engine. Additionally, these cars employ a special system to capture the energy generated during braking and store it in the onboard battery. Below are the functions and advantages of the electric engine: Functions of the electric engine: The electric engine consumes no energy when idle (completely shut off) and uses less energy than the gasoline engine during low-speed driving. On the other hand, the gasoline engine performs better at high speeds, delivering more power for the same engine weight. This means the electric engine is more efficient in stop-and-go traffic during peak hours. Advantages of the electric engine: The primary advantage is that it produces no exhaust emissions, thereby reducing smog pollution levels. Another benefit of the gasoline engine is its ability to recharge the battery while driving. Many electric car owners struggle with the limitations of power cords. The gasoline engine automatically starts and begins charging when the battery level drops, eliminating the need for power cord charging.
