The Accord hybrid system is a technology developed by Honda to improve the fuel efficiency and reduce emissions of their vehicles. The principle of this system can be explained as follows:
1. Combustion Engine: The Accord hybrid system includes a conventional gasoline engine that operates with the Atkinson cycle. This means that the engine can produce high torque and power while using less fuel due to the elongated combustion stroke.
2. Electric Motor: Apart from the gasoline engine, the Accord hybrid system also features an electric motor that provides additional power when needed. The motor can also act as a generator to recharge the battery during deceleration and braking.
3. Battery: The Accord hybrid system has a compact and lightweight lithium-ion battery that stores energy produced by the electric motor, or regenerated during braking. The battery can power the electric motor during low-speed driving or cruising, thereby minimizing the dependence on the combustion engine.
4. Hybrid Power Control Unit: The Accord hybrid system is managed by a power control unit that combines the output of the engine and electric motor in the most efficient way, based on the current driving conditions.
5. Regenerative Braking: The Accord hybrid system uses regenerative braking to collect energy that would normally be lost during braking. This energy is stored in the battery and used to power the electric motor.
6. Eco Assist System: The Accord hybrid system features an Eco Assist system that offers real-time feedback to the driver, encouraging efficient driving habits. The system uses green and white colors to indicate driving efficiency, depending on the driver's actions.
Overall, the principle of the Accord hybrid system involves the integration of a gasoline engine, an electric motor, a battery, and a control system to optimize the use of these resources and create a highly efficient and eco-friendly vehicle.
