Should the Handbrake Be Engaged for Long-Term Parking?

Why doesn't the new Focus automatic transmission move when shifted into reverse?

Check whether the gear is properly engaged. If there are no operational issues, it should be taken for repair. Below is relevant information about automatic transmissions: 1. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, the more gears there are, the more fuel-efficient the transmission. 2. Driving Tips: For manual transmission vehicles, higher RPMs should be used when shifting gears. The engine is designed to operate at higher RPMs, and various components' dynamic balance and rotational inertia parameters are also designed with high RPMs in mind. If the engine operates for extended periods under non-optimal conditions, internal components' load and wear will naturally increase, leading to frequent shaking and knocking, which can affect the engine's lifespan. Choosing 3000 RPM as the shift point ensures that after shifting, the RPMs drop to around 2300, keeping the engine within a healthy operating range.

What is the Difference Between Car Headlights with and Without Lenses?

Difference between car headlights with and without lenses: 1. Some are xenon headlights. They can refract light over long distances, and lens-equipped headlights adjust the light distance according to the car's height fluctuations. 2. After installing lenses, the headlights have better light concentration and become brighter. Below is relevant information about headlight lenses: 1. Essentially, a headlight lens is a convex lens, which has a focusing effect. Parallel light rays refracted by a convex lens can converge at a single point. Similarly, if we place a light source at its focal point, the convex lens can transform it into parallel light. This is the principle behind headlight lenses—using a reflector to focus the light from the bulb at the lens's focal point, which then disperses the light evenly. Such headlights illuminate the road surface very uniformly. 2. The structure of lens headlights determines that their utilization of the bulb's light is not as efficient as that of reflectors. Since lenses alter the path of light through refraction, to achieve a more uniform and perfect light pattern, the incident light must undergo certain processing. Therefore, there is actually a shading mechanism between the lens and the bulb. When the low beams are on, the shader blocks part of the headlight's light in a pre-designed shape, meaning not all the light emitted by the bulb reaches the road surface.

Why Does the Engine Malfunction Light Stay On After Refueling?

After refueling, if the engine malfunction light stays on, it indicates the use of substandard fuel. During the combustion process in the engine, substandard fuel with high impurities and low combustion efficiency can leave residues and unburned fuel in the combustion chamber, occupying space and triggering the engine malfunction light. Solution: Promptly drain the substandard fuel and clean the fuel tank and fuel lines. After cleaning, replace with high-quality fuel. Besides fuel quality, other reasons that can cause the engine malfunction light to stay on include: Sensor Malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors, when damaged, poorly connected, or interrupted, prevent the car's ECU from accurately obtaining engine data, leading to the engine malfunction light. Poor Mixture Combustion: Poor combustion of the air-fuel mixture can cause engine carbon buildup or knocking. Monitored by the oxygen sensor and reported to the ECU, this triggers the malfunction light. Issues like faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines can lead to poor mixture combustion. Turbocharger Issues: Problems with the intake boost pipes or turbocharger can also trigger the engine malfunction light. The most common issue is turbocharger damage, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If the car's intake system is compromised, it can lead to clogged engine pipes, and in severe cases, trigger the engine malfunction light. A dirty air filter that isn't cleaned regularly can cause intake issues. Exhaust Problems: Exhaust system faults can also activate the engine malfunction light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings, with the catalytic converter being the most frequent issue. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily cause catalytic converter failure. Anti-Theft System Fault: If the car's electronic anti-theft system malfunctions or the anti-theft controller doesn't match the engine's electronic controller, the anti-theft system can prevent the engine from operating normally, also triggering the engine malfunction light.

Will the insurance company compensate if the car is flooded without water wading insurance?

If the car is flooded without water wading insurance, the insurance company will not compensate. Here are the relevant details: 1. Insurance company: An insurance company refers to a corporate legal entity established in accordance with the Insurance Law and the Company Law. Insurance companies collect premiums and invest the capital obtained from premiums into assets such as bonds, stocks, and loans. The income generated from these assets is used to pay the insurance compensation specified in the policy. 2. Vehicle insurance: Vehicle insurance, also known as motor vehicle insurance or auto insurance, refers to a type of commercial insurance that covers personal injury or property damage caused by natural disasters or accidents to motor vehicles. Auto insurance is a type of property insurance and is a relatively young category in the field of property insurance.

What happens if water enters the engine and it is started?

It can cause the piston to seize, and in severe cases, the connecting rod may bend. Below is the relevant information: 1. Engine: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Internal combustion engines typically convert chemical energy into mechanical energy. 2. Connecting Rod: It connects the piston and the crankshaft, transmitting the forces acting on the piston to the crankshaft and converting the reciprocating motion of the piston into the rotational motion of the crankshaft.

What is the wading depth of the Vezel?

The maximum wading depth of the Vezel is approximately 600-650mm. The wading depth of the Vezel is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the Vezel is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth must not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in the water, which could cause severe damage due to water ingestion. Assess the underwater road conditions based on the passage of preceding vehicles and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, or the wheels and doors of other vehicles as reference points to judge the water depth before deciding whether to proceed. Be aware of your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not enter the water recklessly; consider taking an alternative route.
