1. Different energy sources
The starter relies on electricity, and electrical energy is converted into mechanical energy. The engine relies on fuel, and internal energy is converted into mechanical energy.
2. Different structures
The starter is mainly composed of an electric motor consisting of a magnetic field (stator), an armature (rotor) and a commutator. The engine is mainly composed of a body group, which is mainly composed of parts such as a cylinder block, a cylinder liner, a cylinder head and a cylinder gasket. The relationship between the two is mainly reflected in the car. When the car starts, the key is first turned on to turn on the starter, so that the starter drives the engine to work, and then the engine can rely on its own combustion, that is, the power inertia, to run continuously.
Internal structure of starter
3. Different power sources
- Engine: The power source of the engine is gasoline or diesel, etc.
- Starter: The power source of the starter is a battery or DC power, etc.
4. Different uses
- Engine: Engine is applicable to both power generation devices and the entire machine including power devices, such as gasoline engines, aircraft engines, etc.
- Starter: Starter is usually used to start large internal combustion engines.
Supplementary information:
Starter: Also called a motor, it is a machine that converts the electrical energy of the battery into mechanical energy, drives the engine flywheel to rotate and realizes the start of the engine.
Engine: A machine that can convert other forms of energy into mechanical energy.
