The two wires above the tram serve the purpose of power supply. The following is an introduction to trams: 1. Introduction to trams: Trams are an important means of urban transportation. Since Werner von Siemens invented the tram in 1881 in Germany, they have been widely used around the world. The 1970s was a period of revival for trolleybuses. In addition to the emergence of a large number of chopper voltage regulation vehicles, a number of new models also appeared, such as AC transmission trams driven by induction motors and trolleybuses with auxiliary power devices. The simplest auxiliary power is a battery, which allows the tram to operate for short distances in areas without overhead lines. Additionally, there are trams with diesel engines as auxiliary power. 2. Classification of trams: Trams are public transportation vehicles powered by electricity, with the electrical energy supplied from overhead power lines, and they are divided into two types: trolleybuses and rail trams.

What is a retarder?

A retarder refers to a device that enables a vehicle to decelerate smoothly when slowing down or descending a long slope, avoiding the wear and heat caused by using the brake. Below is a detailed introduction to retarders: 1. Based on different working principles, automotive retarders can be classified into typical structural forms such as engine retarders, hydraulic retarders, electric turbo retarders, motor retarders, and aerodynamic retarders. 2. According to the form of braking torque application, automotive retarders can be divided into primary retarders (those acting on the front end of the transmission) and secondary retarders (those acting on the rear end of the transmission). 3. When descending long slopes, using exhaust brakes can achieve good braking effects. However, for heavy-duty mining dump trucks, exhaust braking has limited effectiveness and can cause some degree of damage to the engine. Therefore, mining dump trucks equipped with hydraulic-mechanical transmissions are generally fitted with hydraulic retarders.

What are the causes of abnormal noise in a car's expansion valve?

Abnormal noise from a car's expansion valve indicates a blockage in the valve. 1. Causes of blockage: Blockage faults in the thermal expansion valve of the refrigeration system are common, including "dirt blockage" and "ice blockage." The main cause of dirt blockage is the presence of impurities in the system, such as welding slag, copper chips, iron filings, fibers, etc. Ice blockage occurs when there is excessive moisture in the system. 2. Moisture pathways: During installation, insufficient vacuuming time fails to remove all moisture from the pipelines; poor welding techniques at pipeline connections result in air leakage points. When charging the system with refrigerant, the air in the connecting hoses is not purged. Additionally, air can enter when replenishing the system with lubricating oil.

How many days in advance can I renew my driver's license before it expires?

You can renew your driver's license three months before it expires. Here are some other important considerations: 1. If your driver's license is about to expire, you must renew it in advance. Otherwise, your license will be in an abnormal state, and if you continue to drive, you may face charges for driving without a valid license. 2. If the renewal period is exceeded by more than one year: According to the "Regulations on the Administration of Motor Vehicle Driver's Licenses of the People's Republic of China," if the renewal period is exceeded by more than one year, the vehicle management authority shall cancel the motor vehicle driver's license and note it in the registration records. Therefore, all drivers should pay attention to whether their driver's license is about to expire.

Why Change the Oil Filter?

The reason for changing the oil filter is: The oil filter, also known as the oil purifier, is specifically designed to filter the engine oil. When the engine is running, metal impurities generated circulate within the oil. As the oil passes through the oil filter, the filtered clean oil continues to be used, while the impurities are trapped inside the oil filter. Therefore, it is essential to replace the oil filter whenever changing the engine oil. The function of the oil filter is to filter the engine oil, improving its cleanliness and lubricity to reduce engine wear and ensure optimal performance. It is recommended to change the oil filter every 5,000 to 10,000 kilometers. The contaminants in the old oil filter can reduce the viscosity and cleanliness of the new oil, affecting oil circulation speed and potentially damaging the engine.

Is it okay to turn off the engine without shifting to P gear?

It is okay to turn off the engine without shifting to P gear. The correct parking sequence is: first step on the brake to stop, shift to neutral after stopping, then release the handbrake, and finally shift to P gear. This mainly depends on the road conditions when parking. P gear is a common gear in automatic transmission models, usually located at the front of the gearshift console, before the R gear, and its purpose is to lock the axle when the car is stationary on a slope. After shifting to P gear and then pulling the handbrake, the car may still move slightly. This is because the P gear is equivalent to the manual transmission model's gear lock, which only serves as an auxiliary brake. Shifting to P gear first means its locking mechanism has already engaged with the transmission, so the effect of pulling the handbrake at this time is not very noticeable.

What are the precautions for using a turbocharger?

Precautions for using a turbocharger: 1. Use genuine and clean lubricating oil and replace it regularly. The functions of lubricating oil are lubrication, cleaning, cooling, and corrosion prevention; 2. Avoid prolonged idling of the engine; 3. Avoid sudden shutdown after heavy load or high-temperature and high-speed operation; 4. Do not rev the engine excessively before the oil pressure reaches the normal level after starting the engine; 5. Regularly check the operation of the turbocharger. Before driving and after parking, inspect the connections of the air ducts to prevent loosening or detachment, which could lead to turbocharger failure and air short-circuiting into the cylinders. A turbocharger is an air compressor that increases air intake by compressing air.
