The basic structure of a car includes the engine, chassis, body, and electrical equipment. Below is a detailed explanation: 1. Engine: The engine is a crucial component of a car, providing the power needed for the vehicle to move. Currently, the main engines on the market are powered by gasoline or diesel. The engine consists of the crankshaft connecting rod mechanism, valve train, cooling system, fuel supply system, and lubrication starting system. 2. Chassis: The chassis supports and mounts the car's engine and other body components, ensuring the vehicle operates normally. The chassis mainly comprises the transmission system, running system, steering system, and braking system. 3. Body: The body is mounted on the car's chassis and forms the vehicle's exterior. It primarily consists of fenders, cabin assembly, engine hood assembly, roof assembly, luggage compartment partition assembly, trunk lid assembly, rear panel, side panel assembly, floor assembly, rear door assembly, and front door assembly. Additionally, in terms of structure, the body is divided into monocoque (unibody) and body-on-frame, with the main difference being the presence or absence of a rigid frame, also known as the "chassis beam." 4. Electrical Equipment: The electrical equipment mainly consists of the power source and electrical devices.

How to Match a Remote Control?

Matching a remote control involves the following steps: 1. Insert the mechanical key into the ignition lock, then press the learning button on the remote control box with a sharp pen tip. Upon hearing a "beep" sound, quickly turn the ignition key from the LOCK position to the ON position three times (speed is crucial to enter the learning mode). Leave it in the ON position on the third turn. After about 2 seconds, the hazard lights will flash. Press any button on the remote control, and the turn signals will flash three times. Then, press any button on another remote control, and the turn signals will flash three times again, completing the learning process. 2. Enter the car and close all doors. Open the driver's door, insert the key, and turn it on and off five times in a row. On the fifth time, the hazard lights will flash once. Simultaneously, press and hold the lock and unlock buttons on the remote control that needs to be paired, pressing them several times. The hazard lights will flash, and if they flash twice, it indicates the remote control has been successfully matched. Remove the key and test whether the lock and unlock buttons function properly.

Why was the Honda URV discontinued?

Honda URV discontinued for the following reasons: 1. The price positioning is higher than the product level. The Honda URV has a relatively high price, exceeding that of general models in the same class, but its product quality does not match its price. As a mid-size SUV, the Honda URV's space performance is not outstanding enough, and its configuration richness is slightly lower than that of competing models in the same class. 2. Competing models in the same class have advantages in price and configuration, causing the Honda URV to lose competitiveness. The Honda URV's similar model is the Honda Avancier, which is similar in body size and other aspects to the Honda URV but has a lower selling price, resulting in higher sales than the Honda URV. Compared to other mid-size SUVs in the same class, the Honda URV still does not have an advantage in price and configuration. 3. It is about to undergo a model update or upgrade. Currently, only the 2020 model of the Honda URV is available for sale. Honda Motor Company will upgrade the Honda URV and is expected to launch the 2021 Honda URV.
