What Does Dual Engine Hybrid Mean?
3 Answers
Dual Engine refers to the installation of two power engines, a fuel engine and an electric motor. The hybrid technology of Dual Engine (HEV technology) belongs to the full hybrid technology. Unlike other mild hybrid technologies, it has both an engine and an electric motor as power sources, significantly improving power performance while greatly reducing fuel consumption. It is a technology that balances tradition and the future, effectively implementing energy saving and emission reduction, hence the name Dual Engine. Advantages of Dual Engine Hybrid: During operation, it achieves maximum power while operating under optimal conditions of low fuel consumption and minimal pollution. When the internal combustion engine's power is insufficient, the battery's power can supplement it. Since the internal combustion engine can operate continuously, the battery is constantly recharged, allowing it to travel the same distance as a conventional car.

The dual hybrid system is a type of vehicle that combines a gasoline engine with an electric motor to work together. It primarily relies on the electric motor for starting and low-speed driving, while the gasoline engine takes over during high-speed driving and charging. For example, Toyota's system can automatically switch between the two power sources—using pure electric mode for quiet and fuel-efficient operation in traffic jams, and relying on the gasoline engine for highway driving, resulting in impressively low overall fuel consumption. My eight-year-old hybrid car can still travel over 800 kilometers on a single tank of fuel. The brilliance of this technology lies in its ability to recover energy during braking to recharge the battery, eliminating the need for additional charging stations. Although the initial cost is higher, the long-term savings on fuel are significant, and now many automakers are following suit with hybrid models.
The dual hybrid system is essentially a hybrid vehicle that relies on dual power sources: a battery and a fuel tank. I once drove my friend's hybrid Camry, and the most noticeable feeling was how quiet and powerful it was when starting from a red light, just like an electric car. When decelerating by releasing the accelerator, you could hear the buzzing sound of the motor charging. The design principle is actually quite smart: it uses electricity at low speeds to avoid inefficient engine operation, employs both fuel and electricity during rapid acceleration, and maintains the engine at a fuel-efficient RPM during high-speed cruising. It's particularly suitable for city commuting, with fuel consumption dropping to just over 4 liters. However, the chassis needs to accommodate a large battery and motor, so the trunk space is slightly smaller. A mechanic mentioned that the car's battery is unlikely to fail even after ten years of use.
