Can a car engine be directly washed with a water gun? However, the following precautions must be taken: 1. Note 1: The engine must be running during cleaning. 2. Note 2: The water gun should not be directed at any single component of the engine for an extended period. 3. Note 3: After cleaning, immediately use a high-pressure air gun to dry the engine. Relevant information about the engine is as follows: 1. Car engine: It is the device that provides power to the car, serving as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental friendliness. 2. Classification: Based on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.

It is not recommended to directly wash the car engine with a water gun. I know it sounds convenient, but there are many electronic components in the engine compartment, such as sensors, wiring harnesses, and battery connectors. Water entering these areas can cause short circuits, damage the control module of the computer board, and in severe cases, cause the car to suddenly stall. I've seen car owners spend thousands of dollars repairing wiring after doing this, which is really not cost-effective. Especially for older cars, the engine seals are poor, and moisture can easily corrode the wiring connections. The best way to clean the engine is to use a dedicated cleaning spray, then wipe it with a damp cloth, or take it to a professional shop for treatment. Remember, it's safer to operate when the engine is cold; avoid washing with water when the engine is hot, as large temperature differences may cause internal cracks. Safe driving starts here.

What is the standard tire pressure for a minivan?

The standard tire pressure for a minivan is between 2.3 and 2.5 bar. Tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a significant role in the performance and power of the vehicle. The effects of over-inflation are: 1. Reduced friction and adhesion, affecting braking performance; 2. Causes steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates wear on the central tread pattern, shortening tire lifespan. The effects of under-inflation are: 1. Increases the coefficient of friction with the road surface; 2. Makes the steering wheel heavy and prone to deviation; 3. Increases the movement of various parts of the tire, leading to excessive rolling and abnormal heating of the tire.

What Causes Idle Vibration in New Cars?

New cars experiencing idle vibration is normal. During a cold start, the engine speed may vibrate between 900 to 1100 RPM. After warming up, the speed will stabilize around 800 RPM, reaching normal levels. If the idle vibration is excessive, it is advisable to consult professionals at a repair shop or 4S store. Reasons for abnormal idle vibration in cars: 1. Severe carbon buildup in the vehicle, with noticeable symptoms being idle shaking. The carbon deposits should be cleaned. 2. Faulty ignition system or damaged spark plugs, leading to ineffective fuel combustion in the cylinders, causing abnormal idle shaking. In such cases, a detailed inspection at a repair shop or 4S store is necessary. 3. Fuel injector malfunction, where uneven fuel injection among the engine cylinders can also cause idle vibration. The fuel injectors should be inspected and repaired in such scenarios.

How many free maintenance services are provided for a new car?

Generally, the first maintenance service for a new car is free, and some 4S stores may offer customers additional free maintenance services. After reaching the time for the first maintenance, car owners should go to the 4S store on time. If the car is still under warranty, it is recommended that owners perform maintenance at the 4S store. If the car is out of warranty, owners can go to external repair shops for maintenance. It is recommended to check the moisture content of the brake fluid, inspect the tires, and check the thickness of the brake pads during each maintenance service. When the moisture content of the brake fluid reaches 3%, it is necessary to replace the brake fluid immediately. Car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent failures, and extend the service life.

What is the difference between E-type multi-link suspension and multi-link suspension?

The differences between E-type multi-link suspension and multi-link suspension are: 1. Different composition: The E-type multi-link suspension is a suspension structure composed of three or more connecting rods; the multi-link suspension consists of connecting rods, shock absorbers, and damping springs. 2. Different systems: The E-type multi-link suspension is an improvement of the double-wishbone type and is not entirely considered a double A-arm type; the multi-link suspension belongs to the double A-arm suspension and multi-link suspension systems. The suspension is the general term for all force-transmitting connection devices between the vehicle frame and the axle or wheels. Its functions are: 1. To provide cushioning when the vehicle passes over uneven ground; 2. To ensure that the wheels move within a fixed angle, making steering stable; 3. To support the weight of the wheels; 4. To maintain good contact between the wheels and the ground, ensuring that the driving force and braking force generated between the wheels and the ground are accurately transmitted to the vehicle body.
