Automatic transmission fluid should be changed every 2 years or 40,000 kilometers. Transmission fluid, also known as gear oil, is used to keep the gear system clean, lubricate the transmission components to extend their lifespan, and provide effective lubrication even in low-temperature conditions. It also helps reduce oil loss under harsh operating conditions. Maintenance methods for transmission fluid: 1. Change the fluid regularly. 2. Frequently check the fluid level. 3. Avoid coasting in neutral. 4. Avoid skipping gears when upshifting. 5. Do not force the transmission into neutral. 6. Minimize the time spent idling to warm up the car. 7. Avoid gear grinding when shifting. 8. Clean the transmission regularly.

How Many Kilometers Should You Change Your Car's Engine Oil?

Car engine oil should be changed every 5,000 to 10,000 kilometers. The method for changing engine oil is as follows: 1. Use a jack to lift the vehicle, locate the drain plug, and unscrew it to drain the oil; 2. Remove the oil filter and place a container underneath to collect the old oil; 3. Install a new oil filter and add new engine oil. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and removing contaminants; 4. Dampening vibrations and shocks; 5. Preventing rust and corrosion. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance.

What Causes a Manual Transmission Car to Stall After Starting?

Manual transmission cars may stall after starting due to the following reasons: 1. Blocked fuel supply line in the engine; 2. Carbon buildup on engine spark plugs; 3. Use of low-quality fuel; 4. Faulty ignition switch; 5. Low pressure in the car's fuel system; 6. Activation of the car's anti-theft system; 7. Driver operation issues. Solutions for a manual transmission car stalling after starting include: 1. Cleaning the engine's fuel supply line; 2. Cleaning the engine spark plugs; 3. Replacing with higher-grade fuel; 4. Replacing the ignition switch; 5. Inspecting the car's fuel system. A manual transmission car refers to a vehicle that uses a manual gear-shifting mechanical transmission to regulate speed, where the driver manually moves the gear lever to change the gear engagement position inside the transmission, altering the gear ratio to achieve speed variation.

Why Does Lynk & Co Primarily Promote Three-Cylinder Engines?

Increasingly stringent emission regulations are the primary reason, but the analysis isn't thorough enough. Here are some additional points. First, the initial impression of a three-cylinder engine is cost-saving. After all, it has one less cylinder and corresponding components, but user experience is paramount. Today, selling cars at low prices alone isn't sufficient. To enhance user experience, despite having one less cylinder, compensatory measures such as vibration-damping rafts, balance shafts, dual-mass flywheels, and vehicle NVH tuning are implemented to offset the missing cylinder. The cost and time invested aren't worth wasting. Moreover, there's already a ready-made solution from Volvo! Directly using the RIVE-E1.5T four-cylinder engine could save substantial R&D funds, and corresponding models could generate profits in the market sooner. Therefore, adopting a new three-cylinder engine seems not about saving money but rather about incurring losses.

Do tires need to be replaced after 40,000 kilometers?

If the vehicle has traveled 40,000 kilometers but not exceeded 5 years, and the tire wear is not severe, replacement is unnecessary. The following are considerations for tire replacement: Tire replacement principles: Same specifications: Tires of different specifications have varying outer diameters and cross-sectional widths when inflated. Installing them on the same axle will result in uneven load distribution. Same structure: Due to the different carcass structures of radial tires and bias tires, their cushioning performance and circumferential deformation differ. Mixing these two types of tires on the same axle will lead to uneven load-bearing and inconsistent wear. Same material: Same material: Material mainly refers to the carcass cord material. For example, all-steel radial tires and fiber radial tires have significant differences in carcass thickness, cord strength, and heat dissipation performance. Mixing them will affect performance.

Does Bentley have new energy vehicles?

Bentley does have new energy vehicles. The Bentley Bentayga offers a plug-in hybrid model, which is equipped with a 3.0-liter V6 turbocharged engine. The engine has a maximum power output of 250 kilowatts and a maximum torque of 450 Newton-meters, featuring direct fuel injection technology and an aluminum alloy cylinder head and block. The electric motor paired with this engine delivers a maximum power of 94 kilowatts and a maximum torque of 350 Newton-meters. The plug-in hybrid version of the Bentley Bentayga uses a double-wishbone independent suspension at the front and a multi-link independent suspension at the rear. Plug-in hybrid vehicles have a longer driving range than pure electric vehicles and offer better fuel economy than conventional gasoline-powered cars. Plug-in hybrid vehicles fall under the category of new energy vehicles and are eligible for green new energy license plates. In some cities with license plate restrictions, green new energy license plates do not require a lottery for allocation.

What Causes a Strong Gasoline Smell in Car Exhaust?

Car gasoline smell is heavy, which is caused by aging rubber pipes of the carbon canister, gasoline pipe leakage, residual gasoline during fuel pump disassembly, and overfilling of gasoline. The specific reasons are as follows: Aging rubber pipes of the carbon canister: For cars with high mileage, the rubber components in the engine compartment are prone to aging. Residual gasoline during fuel pump disassembly: Disassembling the fuel pump needs to be done inside the car, and during this process, some residue is inevitable. If not cleaned thoroughly, a gasoline smell may also be noticed during vehicle use. Overfilling of gasoline: If gasoline is overfilled, it may flow into the carbon canister through the pipes. The carbon canister, originally used to collect gasoline vapor, will release excess gasoline vapor through the vent holes when gasoline enters. When the air conditioning is in the external circulation mode, the gasoline smell enters the car interior.
