What does dual engine mean in cars?

[TravisAnn]

Dual engine in cars refers to HEV (Hybrid Electric Vehicle), also known as mild hybrid. Although dual engine models belong to hybrid vehicles, they are not classified as new energy vehicles and do not qualify for national new energy subsidies or other policy benefits. These vehicles must also display blue license plates. A dual engine is a highly efficient and low-consumption car equipped with two sets of engines: an electric motor and a gasoline engine. The characteristic of HEVs is that they do not require charging. The battery capacity and motor power in the vehicle are relatively small, serving only as auxiliary support to the engine. They primarily assist during startup, low-speed driving, or uphill sections to reduce the engine's load.
