What is an ECU in a car?

ECU is the control system of a car's engine. Below is relevant information about the car ECU: 1. Composition: It consists of a microcontroller (MCU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as shaping, driving, and other large-scale integrated circuits. 2. Automatic diagnostic function: ECUs generally have self-diagnosis and protection functions. When a system failure occurs, it can automatically record the fault code in RAM and take protective measures to read substitute programs from the aforementioned inherent programs to maintain engine operation. At the same time, these fault messages will be displayed on the dashboard and remain illuminated, allowing the car owner to promptly identify the issue and drive the car to a repair shop.

What to Do When the Wiper Doesn't Work?

Reasons and solutions for wiper failure are as follows: 1. Wiper blade damage: If you usually neglect the maintenance of car wiper blades and find them severely damaged and unable to work properly on rainy days, simply replace a set of wiper blades in time. 2. Wiper motor failure: After opening the car hood, you can see the wiper motor. You can touch the wiper motor by hand. If it feels hot, it indicates an internal short circuit in the motor, and replacing the motor can solve the problem. 3. Wiper linkage problem: There are many connection points in the wiper linkage. If these points have problems, the wiper cannot work properly. You can determine whether it is a linkage failure by observing the operation of the wiper.

How to Check the Engine Number?

The engine number is generally found on the outer surface of the engine block, or on the vehicle's nameplate or the nameplate inside the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number, like a person's ID number, represents each vehicle and contains crucial information about the car. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry practices, and engine attributes for a batch of identical products. It indicates information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose vehicles are required to display the professional manufacturer, model, and production number. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. The engine number, however, is the production serial number of the engine, and each engine has a unique number. Composition of the Vehicle Engine Number: Prefix: Includes the product series code, generation symbol, and regional or company code, which are selected by the manufacturer as needed and must be approved and filed by the industry standardization unit. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and bore diameter. Suffix: Comprises symbols for structural features and usage characteristics. Tail: A distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol. The suffix and tail can be separated by a hyphen (-).

What is the Difference Between Manual and Automatic Air Conditioning in Cars?

The differences between manual and automatic air conditioning in cars are as follows: 1. Operation Differences: Manual air conditioning can only adjust the airflow manually, but its operation is intuitive and easy to understand without overly complex functions, though it offers a single working mode. Automatic air conditioning does not require frequent adjustments; once the temperature is set, it automatically maintains the interior temperature at that level. It also intelligently switches between internal and external air circulation to ensure reasonable air quality inside the vehicle. 2. Fuel Consumption Differences: The compressor in manual air conditioning operates at a constant power, thus consuming engine fuel. Automatic air conditioning can adjust the temperature automatically. When the set temperature is reached, the compressor can pause or reduce its output power. If the temperature rises, the compressor restarts to maintain the set temperature, allowing the engine to save power when idling, thereby achieving fuel efficiency.

The Difference Between Lowering Springs and Coilover Suspension

The differences between lowering springs and coilover suspension are as follows: 1. Price Difference: The advantage of lowering springs lies in their more affordable price, while coilover suspension is relatively expensive, making it suitable for owners with higher budgets. 2. Usage Characteristics: Lowering springs are non-adjustable, making it difficult to achieve a good balance between daily driving and performance. Importantly, modifying with lowering springs requires matching them with corresponding shock absorbers. On the other hand, coilover suspension allows adjustment of both spring height and suspension stiffness as well as damping speed, offering higher playability and practicality, making it suitable for both daily driving and performance.

What is the difference between built-in and external tire pressure monitoring?

The differences between built-in and external tire pressure monitoring are as follows: 1. Price difference: The built-in type is slightly more expensive than the external type. 2. Installation method: Installing a built-in tire pressure monitor takes more time and requires professional assistance to remove the tires, making it difficult for individuals to install themselves. The external type is simpler to install, allowing car owners to do it themselves. 3. Accuracy difference: Due to environmental factors and external forces, the accuracy of the external type is slightly lower than that of the built-in type. 4. Anti-theft difference: The built-in type is more secure as it is installed inside the tire, while the external type has poorer anti-theft performance. Regarding the two types of tire pressure monitoring, users are advised to choose based on their own needs.
