Not every car necessarily has an on-board computer. Older vehicles (those using carburetors for gasoline engines) generally do not have one. Definition of an on-board computer: The computer in a car is also known as the on-board computer (ECU), or electronic control unit. Principle of an on-board computer: It processes simple electronic signals and performs basic calculations using simple logic gates and integrated circuit principles. Typically, the on-board computer is installed under the dashboard on the driver's side or near the windshield wiper linkage. Function of an on-board computer: It receives data from various sensors in the car, processes and computes this information in the electronic control unit, and then sends signals to the engine to control its operation (including functions like the fuel injection system and ignition timing).

How to Determine Liability When Opening the Rear Door Hits Someone: Passenger vs. Driver

When a passenger opens the rear door and hits someone, the liability division between the driver and the door opener depends on specific circumstances. Here are detailed explanations of liability determination: 1. Public Security Authorities: Traffic management departments of public security authorities shall determine the parties' liabilities based on their actions' contribution to the accident and the severity of their faults. 2. Traffic Regulations: According to traffic laws, opening or closing vehicle doors must not affect the normal passage of other vehicles or pedestrians. Therefore, the motor vehicle party generally bears primary liability in such accidents. If other vehicles or pedestrians are at fault, their liability is determined based on the fault circumstances. 3. Theoretically: The door opener should bear full liability for the accident. However, if the driver fails to fulfill their duty of dissuasion or reminder, they should also bear corresponding responsibility.

Best Solutions for Converting a Sedan into a Camper

1. Place an inflatable mattress or cushion in the rear seats. You can utilize the legroom space in the rear seats; when laid flat, it forms a medium-sized bed, suitable for travelers of average height. The advantages are quick setup, no interference with trunk storage, and the ability to drive off at any time. The downside is limited legroom and restricted movement on the bed. This method is more suitable for women and people from southern regions. 2. Fold down the front seats and place a board to create a bed: After folding down the front seats, due to the curvature of the seatbacks, some people place a board on top to form a bed. Others, for convenience, use blankets or cushions to fill the depressions and level the surface for sleeping. The benefit of this method is that it doesn’t interfere with trunk storage, but the drawback is uneven seating. Unless you replace the front seats with RV seats, which may compromise seating comfort. When converting a sedan into a camper, the best solution is the one that suits your needs.

How Many Kilometers Can Two Bars of Fuel Run?

Two bars of fuel can run approximately 60 kilometers. Below are detailed explanations regarding the fuel tank capacity of a car: 1. Meaning of the fuel gauge: The fuel gauge on the dashboard has 5-6 bars, with each bar representing the remaining fuel capacity in the tank. Generally, when the fuel gauge shows two bars remaining, it's time to refuel. 2. Fuel tank capacity measurement unit: The international standard uses liters (L) as the unit for measuring a car's fuel tank capacity, with different countries having their own corresponding standards. 3. Relationship between engine displacement and fuel tank volume: Typically, small cars have a fuel tank capacity of 35-45 liters, while mid-sized cars range around 55-75 liters. A full tank generally allows driving about 500 kilometers. Depending on the engine displacement, lighter cars with smaller displacements have correspondingly smaller fuel tank volumes, whereas heavier cars with larger displacements have larger fuel tank volumes.

Do all second-generation EA888 engines burn oil?

Not all second-generation EA888 engines burn oil. Here are the specific reasons for oil burning: 1. Worn valve seals: Valves are used to prevent oil from leaking into the combustion chamber, but over time, they can wear out or age. Severe wear can affect the sealing of the valves, making it easy for oil to burn. 2. Excessive piston clearance: When a car is used for a long time, incomplete combustion can cause carbon deposits to accumulate on the piston rings. If not cleaned for a long time, this can widen the gap between the piston rings and the cylinder, allowing oil to flow into the combustion chamber and cause oil burning. In severe cases, it can even lead to engine seizure. 3. Driving habits: Frequent rapid acceleration and prolonged high-speed driving can easily damage the lubricating oil film, leading to poor engine lubrication and wear on certain parts, which may also result in oil burning. 4. Excessive oil level: If the oil level is too high and exceeds the maximum mark, the excess oil can easily enter the combustion chamber (due to excessive internal pressure) and form sticky carbon deposits.

What Causes the Buzzing Sound During New Energy Vehicle Charging?

New energy vehicle charging buzzing sound reasons are as follows: Dust accumulation in charging system: Over time, dust accumulation in the charging system can also produce louder sounds. During charging, new energy vehicles generate static electricity, which attracts environmental dust to the charging system, leading to poor heat dissipation. This causes the temperature to spike immediately when the charging gun is plugged in, forcing the fan to operate at maximum speed continuously. Heat from current-voltage conversion components: The heat generated by current-voltage conversion components triggers the cooling fan of the electronic control system, which is a normal phenomenon. If the ambient temperature is low with good heat dissipation, the fan may not start or operate at low speed. However, if the temperature exceeds 40 degrees, the fan will start running, and if it exceeds 50 degrees, the fan will operate at high speed, producing a noticeable buzzing sound that the owner can hear.

How Long Can a Touch-Up Paint Pen Last?

Touch-up paint pen durability introduction: If properly maintained, touch-up paint applied with a pen can last two to three years without issues. However, many factors can affect its longevity, and poor maintenance after application may cause it to peel off in less than a year. Touch-up paint pens provide only a basic solution—wiping the area and dabbing on the paint. If the area is frequently touched, exposed to direct sunlight, or subjected to rain, the paint may peel off. Below are the characteristics of automotive touch-up paint pen effects: 1. Quick-drying: Due to usage environment constraints, touch-up paint pens must feature rapid drying at room temperature; otherwise, the paint may run or attract dust, affecting appearance. 2. Versatility: Touch-up paint pens are formulated based on standard colors, offering a degree of versatility. However, as mentioned in the color-matching principle above, they cannot perfectly match vehicles with varying degrees of aging, and the color difference may be more noticeable compared to custom-mixed spray paint.
