The power steering system of a car can be roughly divided into two categories: hydraulic and electric. The working principle of the Electro-Hydraulic Power Steering (EHPS) system is the same as that of the traditional mechanical hydraulic power steering system, using the power generated by the electric motor to assist the driver in steering. The following is a related introduction to the power steering system: 1. Principle: The Electro-Hydraulic Power Steering (EHPS) system adds the function of an electric steering pump, and the start and stop of the electric pump are controlled by the ECU. When no steering action is performed, the electric steering pump is turned off, unlike the mechanical hydraulic power steering pump, which is always connected to the engine through a belt. 2. Composition: The Electric Power Steering (EPS) system consists of a torque sensor, a control unit (ECU), a power motor, and a mechanical steering gear.

Veteran drivers say the power steering system is like a helper that makes driving easier. It uses a hydraulic pump or motor to assist in turning the steering wheel. In traditional hydraulic power steering systems, there's an engine-driven pump that sends fluid into the steering gear, where hydraulic pressure moves the rack, making steering effortless. When you turn the wheel, the hydraulic valve opens, allowing fluid to flow and amplify the force. Nowadays, electric power steering is more popular—it uses sensors to detect the steering angle, and then the computer controls the motor to provide assistance, saving fuel and improving precision. I've driven old cars without power steering, where turning the wheel was exhausting, but after installing it, handling became smooth, especially during high-speed lane changes. It's important to check the hydraulic fluid level to avoid leaks that could affect performance. Electric systems may also overheat and require maintenance. Overall, this system enhances driving safety and comfort, making it a must-have feature in cars.

Is the cigarette lighter accurate for measuring battery voltage?

Measuring battery voltage through the cigarette lighter can have inaccuracies. Here are specific details about the accuracy of cigarette lighters: 1. The connection between the cigarette lighter and the battery: The cigarette lighter can only serve as an auxiliary tool and may be used as a daily voltage reference. However, it is recommended to use a multimeter to directly measure the battery voltage for the most accurate results. When the vehicle is not started, the cigarette lighter uses power from the battery. After starting, it uses power from the generator. 2. The function of the cigarette lighter: The cigarette lighter is a component found in all cars, designed to provide a convenient flame source for smokers. Some manufacturers produce cigarette lighters not for lighting cigarettes but solely for drawing power from the vehicle.

What Causes the Car Key to Not Turn When Inserted?

Here are the specific reasons why a car key may not turn when inserted: 1. Improper steering wheel angle: After starting the vehicle with the key, the steering wheel automatically unlocks. Sometimes, if the steering wheel is parked at a certain angle, this angle may allow the key to turn for ignition but not unlock the wheel, resulting in the key not turning. You can gently turn the key with your right hand while lightly rotating the steering wheel with your left hand to naturally unlock it. 2. Steering wheel lock: When the car is turned off, if the steering wheel is turned left or right or the wheels are not straight when parked, the force can cause the steering wheel to rotate, triggering the self-locking function. This locks the steering column and the steering lock pin together, preventing the steering wheel from moving. Even if the key is inserted and turned forcefully, it won't budge. This is the vehicle's anti-theft system detecting a potential theft risk and locking the steering wheel to prevent theft.

What is the normal tire pressure for a Civic?

The normal tire pressure range for a Civic is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The indicator for the Honda Civic's tire pressure monitoring system is a semi-enclosed exclamation mark on the car's dashboard, which is enabled by default and does not require manual activation. However, under normal circumstances, the Civic's tire pressure monitoring system does not display or allow access to specific tire pressure data. It only alerts when there is abnormal tire pressure. Generally, a tire pressure above 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing elasticity and increasing the load on the car during driving. Hazards of underinflated tires: Increases friction with the road surface, raising fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of tire parts, causing abnormal heat due to excessive rolling; weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually triggers an alarm if below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system still records the previous data, causing the indicator light to come on. Simply reset the tire pressure to resolve this. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light will activate. A damaged sensor must be replaced with a new one.

What are the emission standards for annual vehicle inspections?

Annual inspection emission standards are as follows: Carbon monoxide 700mg/km, Non-methane hydrocarbons 68mg/km, Nitrogen oxides 60mg/km, PM particulate matter 4.5mg/km, etc. Below is relevant information about vehicle annual inspections: 1. Cancellation of environmental protection labels: China's transportation authorities have issued new regulations stating that as long as the vehicle passes the annual inspection, the environmental protection label can be removed. 2. Cancellation of compulsory insurance labels: Currently being piloted in Beijing, vehicles in Beijing can replace physical compulsory insurance labels with electronic insurance policies. 3. Inspection-free period: Non-operational passenger vehicles are exempt from inspection for the first 6 years, but owners must submit compulsory insurance policy and vehicle tax certificate to the vehicle management office every 2 years, then directly apply for the inspection compliance label from traffic police authorities.

Are hybrid vehicles subject to traffic restrictions based on license plate numbers?

Hybrid vehicles are subject to traffic restrictions based on license plate numbers. Only pure electric new energy vehicles or plug-in hybrid models classified as new energy vehicles by national regulations are exempt from these restrictions. In other words, unlike traditional license plates, vehicles with special new energy vehicle license plates are not subject to traffic restrictions. Here are the specific details about hybrid vehicles: 1. Definition: Hybrid vehicles offer high fuel efficiency and superior driving performance. They use fuel-powered engines, but with the assistance of electric motors during startup and acceleration, fuel consumption can be reduced. Simply put, compared to similarly sized conventional vehicles, hybrid vehicles have lower fuel costs. 2. Hybrid Power: Generally, hybrid refers to oil-electric hybrid power, which combines fuel (gasoline, diesel) and electric energy. Hybrid vehicles are driven by an electric motor that assists the engine. Additionally, the electric motor assisting the engine can generate strong and smooth power during normal driving, allowing drivers to enjoy more powerful starts and acceleration while achieving higher levels of fuel economy.
