What is an automobile starter?
The car starter is a component that converts the electrical energy from the battery into mechanical energy to drive the engine flywheel to rotate. It consists of a DC motor, a transmission mechanism, and an electromagnetic control switch. Its voltage is divided into 12V and 24V types, and the tooth head design includes with cover and without cover styles. The service life of domestic models is approximately 6 years or 100,000 kilometers, while that of joint venture and imported models can reach 10 years or 200,000 kilometers. When working, the driving gear of the transmission mechanism engages with the flywheel gear ring to transmit torque, and the engine starts and automatically disengages after that. The electromagnetic switch controls the circuit connection and disconnection.
This component replaces the traditional manual starting method and becomes the mainstream configuration. According to the differences in the transmission mechanism, it is divided into types such as forced engagement type, armature movement type, and reduction type. The electromagnetic control type is remotely controlled by relays to the main circuit and is widely used in automobiles, generators, and heavy machinery. During maintenance, it is necessary to check the wear of the gears, the contacts of the electromagnetic switch, and the state of the magnetic coil, with a particular focus on the abnormal impact sound caused by the abnormal engagement of the driving gear and the flywheel gear ring. The domestic manufacturing process is mature, making it have a high cost-performance ratio.
The working principle of this component is the energy conversion process based on Ampere's law that we encountered in junior high school physics, that is, the force acting on an electrified conductor in a magnetic field. The motor includes necessary components such as the armature, commutator, magnetic poles, brushes, bearings, and casing.
Before the engine operates on its own power, it must be rotated by an external force. The process of the engine transitioning from a stationary state to being able to operate independently by external force is called engine starting. The common starting methods for the engine include manual starting, auxiliary gasoline engine starting, and electric starting. Manual starting is done by pulling a rope or hand-winding, which is simple but inconvenient and labor-intensive. It is only suitable for some small-power engines and is retained as a backup method in some cars; auxiliary gasoline engine starting is mainly used for large-power diesel engines; the electric starting method is simple to operate, starts quickly, has the ability to repeat starting, and can be remotely controlled, so it is widely used in modern cars.
During the process of car transactions, we must conduct road tests. However, during the road test, we must consider the vehicle's power performance. So, what is the power performance of a car?
The power performance of a car refers to the process of straight-line driving on a good road, which can be determined by the longitudinal external force. It is the ability to reach the average driving speed. From this definition, we can see that for the road, it must be a good surface, level or slope, and the movement mode can be a straight-line process. For external force factors, it can be determined by the longitudinal external force to make the movement have a certain ability.
For movement ability, there are mainly three indicators, such as the maximum speed of the car, acceleration time, and maximum climbing slope. For vehicles traveling on a good level road, if they can reach the highest speed, we call it the maximum speed. For acceleration time, it is usually the acceleration time from starting at rest and the acceleration time for overtaking. This time indicates the acceleration ability of the car. "t" represents the time from starting at rest, which is generally in first or second gear for starting, and then gear shifting is processed gradually. If it reaches a certain predetermined distance, the time required for the vehicle speed is the time from starting. The acceleration time for overtaking can also be represented by "t". For some cars with the highest second gear, their speed is around 30 or 4, and full acceleration takes some time on some highways.
