What is the difference between hybrid and dual engine?
2 Answers
Difference between hybrid and dual engine: 1. Different scope: Hybrid generally refers to oil-electric hybrid; Dual engine refers to the installation of two power engines, namely fuel engine and electric motor. 2. Different power: The electric power system used in hybrid vehicles includes high-efficiency and enhanced electric motors, generators and batteries; Dual engine belongs to the complete hybrid technology, using the power source of engine and electric motor. The dual engine system can intelligently combine the engine and motor according to different driving conditions such as starting, driving, accelerating, decelerating, and parking, giving full play to their respective advantages, so that the vehicle can achieve the working condition of low-speed driving by motor and medium-high speed driving by both. Dual engine models do not need to be charged by external power supply during daily use, and the vehicle can charge and discharge by itself while driving.
The difference between hybrid and Dual Engine is quite interesting. Hybrid is a general term for hybrid power, encompassing various technical approaches such as plug-in hybrids and range-extender hybrids, with the core idea being fuel efficiency through the combined operation of a gasoline engine and an electric motor. Dual Engine specifically refers to Toyota's hybrid system, which uses a planetary gear structure, allowing the engine and motor to work in particularly close coordination, achieving high efficiency and fuel savings without external charging. For example, hybrid systems from other brands might rely on plug-in charging to extend pure electric range, but Dual Engine achieves this by automatically recovering energy during driving to charge the battery. These two systems also differ in driving experience; Toyota's Dual Engine is exceptionally quiet at low speeds, and the engine engagement at medium to high speeds is smoother. However, many domestic brands' hybrid technologies, like BYD's DM-i, are advancing rapidly, with fuel efficiency catching up. The key is to choose based on personal needs and budget.
