Is It Advisable to Buy a Car with Flooded Floor?

Is It Advisable to Buy a Car with Flooded Floor? A car with water reaching the floor level is generally acceptable, but it is still recommended to have it further inspected at a 4S dealership. Below are the specific reasons and solutions: Reasons: The main concerns with a flooded vehicle are damage to the engine and electrical systems. Generally, if the water level is below the air intake, it is considered safe. Different car models have varying heights for the engine air intake and different levels of electrification and lowest electrical component positions. In most cases, a water level slightly above the cabin floor is not a major issue. Solutions: Notify the insurance company and request an on-site inspection by the insurer's staff or an authorized third-party appraiser. However, in situations with a high volume of flood-damaged vehicles, insurance companies may not be able to respond promptly. In such cases, the owner or policyholder can take photos of the flooded scene with a camera or mobile phone as evidence for the claim. Before the tow truck arrives, disconnect the vehicle's battery immediately to prevent accidental startup during towing, which could exacerbate the damage. You can also request towing assistance from the insurance company.

How Many Points Are Deducted for Overloading a Private Car?

For private cars with less than 20% overloading, 3 points will be deducted along with a fine; for overloading exceeding 20%, 6 points will be deducted along with a fine. Generally, the passenger limit for private cars is only 5 people, so carrying just one extra person results in a 20% overloading rate, making it easy to incur heavy penalties if not careful. According to the driving license point deduction regulations: If a motor vehicle driver commits any of the following violations, 12 points will be deducted at once: driving a commercial passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by more than 20%. If a motor vehicle driver commits any of the following violations, 6 points will be deducted at once: driving a commercial passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20%, or driving other passenger vehicles with passengers exceeding the approved capacity by more than 20%; driving a truck with cargo exceeding the approved load capacity by more than 30% or carrying passengers in violation of regulations.

What does instantaneous fuel consumption of 1.2L/h mean?

Instantaneous fuel consumption refers to the fuel consumption of a vehicle at a specific moment, reflecting the transient working condition of the car. When the vehicle is in motion, the unit displayed is "liters per 100 kilometers (L/100Km)", whereas when the engine is running but the vehicle is stationary, the displayed unit is "liters per hour (L/H)". More relevant information is as follows: Instantaneous fuel consumption value: A high instantaneous fuel consumption does not necessarily mean that the average fuel consumption will be high. Since modern fuel-injected engines can cut off fuel supply during coasting, some models may show an instantaneous fuel consumption as low as 0. Significance of instantaneous fuel consumption: By observing the instantaneous fuel consumption, car owners can understand the engine's fuel consumption under different conditions, such as when the vehicle is stationary and the engine is idling. Additionally, instantaneous fuel consumption can help understand the fuel consumption per 100 kilometers at different speeds (as the drag coefficient, which significantly affects fuel consumption, is proportional to the square of the speed), thereby helping to identify the vehicle's most economical speed.

How is carbon deposit formed?

Here is a detailed introduction to the formation of carbon deposits: 1. Carbon deposits are residues produced by the incomplete combustion of fuel and lubricating oil blow-by gases (mainly composed of hydroxy acids, asphaltenes, tar, etc.). The formation of deposits is directly related to the vehicle's "fuel" and "lubricating oil". 2. If oil quality and driving habits are neglected for a long time, the wax and gum substances in gasoline will accumulate and thicken, hardening upon repeated heating to form carbon deposits. 3. If the engine experiences oil burning or if low-quality gasoline with many impurities is used, valve carbon deposits will be more severe and form faster. 4. Due to the control characteristics of fuel-injected engines, fuel is injected before ignition in each cylinder working cycle. When the engine is turned off, ignition is immediately cut off, but the fuel injected during the working cycle cannot be recovered. It adheres to the intake valves and combustion chamber walls, where gasoline easily evaporates, leaving behind wax and gum substances. Over time, these substances accumulate and thicken, hardening upon repeated heating to form carbon deposits.

What procedures are required for converting a private car to natural gas?

After converting a private car to natural gas, it is necessary to go to the vehicle management office to stamp the dual-fuel chapter on the duplicate of the driving license, proving that the oil-to-gas conversion was carried out at a modification factory recognized by the vehicle management office. Below is part of the introduction about converting a car to natural gas: Heating system: After converting a private car to natural gas, attention should be paid to the heating system, mainly for winter. When the temperature is too low, the rubber parts inside the pressure reducing device will become stiff, causing abnormal operation and making the vehicle unable to run normally, with a high failure rate. Since most taxis have not cleaned the engine water channel, the heating for the natural gas pressure reducing device is insufficient. Vehicle modification certificate: After the vehicle modification is completed, the vehicle modification certificate issued by the modification unit should be held together with the modification application form to the vehicle management department to handle the motor vehicle alteration procedures. Generally, formal oil-to-gas conversion manufacturers will handle the gas conversion procedures for vehicles converted at their factory.

How to Check the Camshaft Timing on Nissan Qashqai?

Nissan Qashqai camshaft timing marks are located on the gears and chains. The function of the camshaft in a car is to control the opening and closing of the valves. Camshafts are typically forged from high-quality carbon steel or alloy steel, and can also be cast from alloy cast iron or ductile iron. The journal and cam working surfaces are polished after heat treatment. Symptoms of a damaged camshaft in a car are as follows: 1. The car has a high-voltage spark, but it takes a long time to start, though it eventually runs; 2. During the starting process, the crankshaft may reverse, and backfire may occur in the intake manifold; 3. The car idles unevenly and shakes severely, similar to a cylinder misfire; 4. The car lacks acceleration and cannot run properly, especially when the RPM exceeds 2500; 5. The vehicle experiences high fuel consumption, excessive exhaust emissions, and black smoke from the exhaust pipe.
