What is the difference between Dual Engine and hybrid?
2 Answers
The differences between Dual Engine and hybrid are as follows: 1. Different scopes: Hybrid has a broader scope. Broadly speaking, Dual Engine belongs to hybrid. Narrowly speaking, there are two types of hybrid power in the world: one is called Dual Engine, and the other is called other hybrid power. Hybrid generally refers to oil-electric hybrid, where a car is equipped with both a conventional fuel engine and an electric motor, each operating under its optimal working conditions to achieve efficient energy utilization. Dual Engine refers to the installation of two power engines, a fuel engine and an electric motor. 2. Different power: Generally, the electric power system used in hybrid cars includes highly efficient and reinforced electric motors, generators, and batteries. The batteries used can be lead-acid batteries, nickel-manganese-hydrogen batteries, or lithium batteries. The hybrid technology of Dual Engine belongs to full hybrid technology. Unlike other mild hybrid technologies, it has two power sources, an engine and an electric motor, which significantly improves power performance while greatly reducing fuel consumption. It is a technology that combines tradition and the future, implementing energy-saving and emission reduction in practice, hence the name "Dual Engine".
I've driven for many years and studied various hybrid technologies. 'Dual Engine' is actually Toyota's own hybrid technology brand name, specifically referring to their hybrid power system. Hybrid, on the other hand, is a broader concept encompassing all vehicles that use both fuel and electric power sources, including plug-in hybrids, full hybrids, mild hybrids, and more. The Dual Engine falls under the full hybrid category, characterized by not requiring charging as the battery is charged by the engine and brake energy recovery, making it hassle-free to drive. Hybrid vehicles cover a wider range; for instance, plug-in hybrids require manual charging to enjoy pure electric driving. Toyota's Dual Engine system uses a planetary gear design to distribute power, ensuring smooth operation and fuel efficiency, while other brands may have different hybrid structures. For example, BYD's DM-i is a plug-in hybrid that can be charged for longer electric-only range. When choosing, it's important to consider whether charging convenience is a priority for you.
