It may be due to improperly installed sealing rings of the fuel pump inside the tank. Here are the relevant details: 1. Fuel Tank Capacity: The fuel tank capacity (L) refers to the size of the tank and measures the amount of fuel a vehicle can carry. The fuel tank capacity determines the driving range. For two cars with identical engines, the one with a larger fuel tank can travel farther. 2. Fuel Pump: The electric fuel pump is a crucial component of the electronic fuel injection system in a car engine. Its primary function is to supply fuel at a certain pressure to the engine's fuel injection system.

What is the difference between 1.5T and 1.5L engines in cars?

The difference between 1.5T and 1.5L engines in cars lies in the type of engine: the 1.5T uses a 1.5-liter turbocharged engine, while the 1.5L uses a 1.5-liter naturally aspirated engine. Naturally aspirated engines have a simpler working principle, resulting in lower failure rates during use. Turbocharged engines, on the other hand, have a more complex working principle and operate at higher temperatures, which can lead to a slightly higher failure rate compared to naturally aspirated engines. The car engine is the power-generating device of a vehicle, often referred to as the heart of the car, determining its power, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems, among others.

What Causes the Steering Wheel to Make Noise When the Nissan Sylphy Goes Over Bumps?

The main reasons for the noise are as follows: 1. The steering column is not lubricated, resulting in high friction. 2. Insufficient power steering fluid. 3. Issues with the universal joint. 4. Aging and hardening of the rubber bushings on the suspension stabilizer bar links. 5. Damage to the wheel bearing. Note: If you notice noise from the steering gear while driving, it's best to find a safe place to pull over. If the noise is severe, it's advisable to call for a tow truck. If the noise only occurs on bumpy roads or comes and goes, you should promptly reduce your speed, avoid making sharp turns, and drive slowly to the nearest 4S shop or repair facility for inspection. Do not continue driving under risky conditions.
