Retardation refers to maintaining a decelerated state without needing to press the brake during downhill driving. Below are relevant introductions about retarders: 1. Introduction 1: The retarder serves as an auxiliary device to the braking system, mainly applied in buses over 5 tons and trucks over 12 tons. For vehicles frequently operating in mountainous or hilly areas, it enables sustained speed reduction or stable speed maintenance during long descents while alleviating or eliminating the load on service brakes. 2. Introduction 2: Based on different working principles, retarders can be categorized into engine retarders, hydraulic retarders, electric turbo retarders, motor retarders, and aerodynamic retarders. According to the form of braking torque application, they can be divided into primary retarders (acting on the front end of the transmission) and secondary retarders (acting on the rear end of the transmission).

What are the characteristics of a two-shaft transmission?

The characteristic of a two-shaft transmission is that the input shaft and output shaft are parallel, with no intermediate shaft. Here is a related introduction to the two-shaft transmission: 1. Introduction: The two-shaft transmission features two shafts: input shaft I and output shaft II, which are parallel to each other. Power is input from the input shaft and transmitted directly to the output shaft through a pair of gears. Each gear uses a pair of gears for transmission, and the rotation direction of the output shaft (transmission output shaft) is opposite to that of the input shaft (engine crankshaft). The two-shaft transmission is mainly used in front-engine, front-wheel-drive vehicle transmissions. 2. Application: In mid-size and light passenger cars with front-engine, front-wheel-drive or rear-engine, rear-wheel-drive configurations, the two-shaft transmission is adopted due to the requirements of overall structural layout. It has a simple and compact structure and is widely used in passenger vehicles.

Why Are Used Paladins So Cheap?

Here are the specific reasons for the low price of used Paladins: 1. Low Resale Value: The resale rates of the Paladin over the past five years are 67.44%, 60.20%, 51.62%, 44.59%, and 35.64% respectively. According to statistics from the China Automobile Dealers Association, the average resale rate for used cars in China is 70% in the first year and 60% in the third year. The Paladin's resale rate in the third year is below the average, making it a model with relatively low resale value. 2. Frequent Malfunctions: Used Paladins often experience issues such as water leakage in the body, oil burning, coolant leakage, and other body accessory failures. If you're choosing a Paladin for off-road purposes, consider opting for an earlier model.

Why is the keyless entry not sensitive?

The reason why the keyless entry is not sensitive is that the car key battery is about to run out or there is a problem with the car's sensor chip system. Here is a related introduction about the car keyless entry system: 1. Introduction: The car keyless entry system, referred to as PKE, adopts the world's most advanced RFID radio frequency technology and the most advanced vehicle identity coding recognition system. It is the first to apply a miniaturized, low-power RF antenna development solution and successfully integrates the remote control system and the keyless system, following the traditional whole vehicle circuit protection. It truly achieves a dual RF system and dual anti-theft protection, providing the utmost convenience and safety for car owners. 2. Working principle: By embedding a chip in the ignition key, each chip contains a fixed ID. Only when the ID of the key chip matches the ID of the engine can the car start. If they do not match, the engine cannot start.

Can you park by the roadside with a solid white line?

Solid white lines have no direct relation to parking permissions. A solid white line actually serves as the boundary line for motor vehicle lanes, used to separate motor vehicle lanes from non-motorized vehicle lanes or sidewalks. There is no inherent connection between solid white lines and parking permissions. When there are solid white lines by the roadside, other traffic signs and markings are needed to determine whether parking is allowed. Below are relevant explanations: 1. Prohibition of both long-term and temporary parking: This applies when there is a solid yellow line by the roadside, or a 'No Parking' sign marked with an '×', or a 'No Parking' sign with a diagonal line and the word 'Stop', or when the curb edge is painted with a solid yellow line. 2. Temporary parking allowed: This applies when there is a dashed yellow line by the roadside, or a temporary parking sign marked with '', or when there are regular yellow blocks painted on the curb edge.

What is the general capacity of a car battery?

The battery capacity of small cars varies from 32ah to 80ah, while the battery capacity of vans is typically 32ah, 36ah, 40ah, 45ah, or 48ah; the battery capacity of sedans is usually 40ah, 45ah, 54ah, or 60ah. Below is more information about car batteries: 1. Introduction: A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. The commonly referred-to car battery is mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Working Principle: Inside the battery, a lead plate filled with sponge-like lead serves as the negative electrode, while a lead plate filled with lead dioxide serves as the positive electrode, with 22~28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.

How much fuel does a car consume per kilometer?

Car fuel consumption per kilometer is 5-8 liters. Fuel consumption is generally related to the car's displacement. For household economy cars, the fuel consumption per 100 kilometers is approximately 5L, 7L, 10L, and 12L for 1.0, 1.3, 1.6, and 2.0 engines, respectively. However, fuel consumption is a complex factor and also depends on the car's performance, road conditions, and the driver's skills. Car fuel consumption is directly related to the engine temperature and fuel efficiency. Both excessively high and low temperatures will lead to increased fuel consumption. The engine's working water temperature should be maintained between 80°C and 90°C. Preheating the engine during cold starts can significantly save fuel. Cars must be regularly maintained. The intake system must be kept clean and unobstructed. The air filter should be frequently cleaned, the tension of all belts should be appropriate, tire pressure should not be too low, and brake shoe clearance should be regularly adjusted to avoid friction.
