What is a starter composed of?

Modern starters consist of three main components: the electric motor, the transmission mechanism, and the control device. Specifically designed to start the engine, starters require high torque and therefore draw a large current, often reaching hundreds of amperes. This characteristic distinguishes them from generators. Below is an introduction to modern starters: 1. The DC starter is composed of a DC series-wound motor, an operating mechanism, and a clutch mechanism. Designed specifically to start the engine, it requires high torque and draws a large current, often reaching hundreds of amperes. The starter uses a DC series-wound motor, with both the rotor and stator wound with relatively thick rectangular-section copper wire. The drive mechanism employs a reduction gear structure, while the operating mechanism uses an electromagnetic attraction method. 2. Transmission mechanism (engagement mechanism): During engine startup, it engages the starter's drive gear with the flywheel ring gear to transmit the starter's torque to the engine crankshaft. After the engine starts, it automatically disengages the gear. 3. Electromagnetic switch: The starter's control device, which controls the circuit's on/off state.

Can Spark Plugs Be Reused After Cleaning?

If the wear level is low after cleaning, spark plugs can continue to be used. Generally, they should be replaced after driving 40,000 to 60,000 kilometers under normal maintenance conditions. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris such as leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage wires in the firing order and secure the cover.

When will the China VI emission standard be implemented in Zhejiang?

Zhejiang implemented the China VI emission standard on July 1, 2019. From this date, China V vehicles could no longer be registered. However, for vehicles that were sold and had a unified motor vehicle sales invoice issued before July 1, 2019, as well as those transferred from other provinces that meet the China V emission standard, registration and transfer procedures could still be processed by the traffic management department of the public security authorities before October 1, 2019 (excluding this date). More information about the China VI standard is as follows: 1. The China VI emission standard is an upgraded version of the current China V emission standard. It imposes stricter and more scientific requirements on vehicle exhaust emissions. 2. A China VI vehicle is one that meets the national sixth-stage motor vehicle pollutant emission standard, while a China V vehicle meets the fifth-stage standard. Different emission standards have varying limits on vehicle pollutant emissions. From China I to China VI, the limits on vehicle exhaust emissions have become increasingly stringent, with the China VI standard being at least 50% stricter than the China V standard.

What is the difference between hybrid and pure electric vehicle license plates?

Difference between hybrid and pure electric vehicle license plates: 1. The first digit of the special license plate for small new energy vehicles uses the letters D or F. 2. The sixth digit of the special license plate for large new energy vehicles uses the letters D or F. D represents pure electric new energy vehicles, while F represents plug-in hybrid vehicles and fuel cell vehicles (non-pure electric new energy vehicles). Here is an introduction to electric vehicles: 1. EV: Pure electric vehicle. Although China's pure electric vehicle technology is already very mature, due to various reasons, it is still difficult to achieve industrialization of pure electric vehicles in the short term. 2. HEV: Hybrid electric vehicle. The most important feature of HEV is that it does not need to be charged. Its operation mode is no different from that of ordinary fuel vehicles. The battery capacity and motor power in the vehicle are relatively small, only playing an auxiliary role to the engine. It reduces fuel consumption by recovering kinetic energy during braking and appropriately reducing engine load. 3. PHEV: Plug-in hybrid electric vehicle. Unlike HEV, PHEV has a much larger battery capacity, generally above 10kWh, while HEV's power battery is usually around 1~2kWh. 4. EREV: Extended-range electric vehicle. The pure electric range of EREV models is generally much higher than that of PHEV models.

What does OTA upgrade mean?

OTA upgrade refers to Over-the-Air technology for firmware and software updates. OTA not only provides a more convenient way for vehicle upgrades but also allows consumers to experience a smarter and more convenient driving experience. OTA stands for Over-the-Air Technology, which means downloading updates remotely. It involves downloading new software update packages from remote servers via the internet to upgrade the system. Simply put, OTA is like periodic system updates on smartphones, allowing remote upgrades to enhance the vehicle's features. OTA can be divided into three types: SOTA, FOTA, and DOTA. SOTA is for upgrading infotainment apps; FOTA is for upgrading underlying control software, and DOTA is for fault diagnosis and online repair upgrades. The significance of OTA upgrades: Quickly fix system defects. Traditional vehicles require a recall process by the manufacturer to address system defects discovered during user operation, which involves returning the vehicle to the factory for a unified system upgrade. OTA technology can remotely and quickly fix defects via data packages, significantly reducing the risks associated with lengthy recall processes. Rapid iteration and improved product and user experience. Due to the advanced hardware in product design, smart connected vehicle operating systems can gradually unlock new features, optimize product experience, and provide better system services through successive OTA upgrades. Save time and money for both parties. Traditional recalls involve internal and external approval processes, which are costly in terms of time and money. OTA upgrades can greatly reduce the costs associated with software defect recalls.

What maintenance should be done at 60,000 kilometers?

At 60,000 kilometers, a major maintenance service is required for the car. Major maintenance is typically performed every three years or 60,000 kilometers, and it's best to complete all the items listed in the maintenance manual. Major maintenance for a car is in contrast to minor maintenance. Major maintenance has longer intervals, higher mileage requirements, and more items to service, while minor maintenance has shorter intervals, lower mileage requirements, and fewer items. Below is an introduction to the related car maintenance items: 1. Oil and filter replacement: This should be determined based on the road conditions frequently driven on. Under normal circumstances, the oil should be changed every 5,000 kilometers, but in dusty conditions, it should be changed every 3,000 kilometers. 2. Brake pad inspection and replacement: Generally, the lifespan of brake pads is around 4-5 years or 40,000 kilometers. However, the wear level varies depending on driving habits, road conditions, and speed. 3. Spark plug inspection and replacement: Spark plugs typically last 2-3 years or 20,000-30,000 kilometers. If the vehicle experiences a lack of power or acceleration shuddering, it may indicate a problem with the spark plugs. 4. Throttle body and fuel injector cleaning: Over time, the throttle body and fuel injectors can accumulate dirt or carbon deposits and require regular cleaning. Generally, after driving over 50,000 kilometers, inspection and cleaning are necessary. 5. Brake fluid replacement: In addition to brake pads, brake fluid should also be replaced regularly. It can be replaced along with the brake pads or based on the mileage driven. 6. Pay attention to the tires, especially the spare tire: The typical lifespan of car tires is 4-5 years. Even with low mileage, tires often exposed to sunlight can age prematurely.
