How to Deal with Steering Wheel Pulling to the Left When Braking?

Steering wheel pulling to one side may be due to an imbalance in the brake system's left and right calipers acting on the brake pads. Replacing the left and right calipers can resolve this issue. If there are no issues with the braking system, it is necessary to inspect the tires on both sides, checking tire pressure and the degree of wear on both sides. Four-wheel alignment is based on the vehicle's four-wheel parameters, adjusted to ensure good driving performance and a certain level of reliability. Pay attention to brake pull, which refers to the driver's driving habits or steering under special circumstances.

Does the Fuel Injector Need Cleaning?

Fuel injectors need to be cleaned regularly. The fuel injector is one of the key components of an electronically fuel-injected engine, and its working condition directly affects the engine's performance. However, many car owners overlook the cleaning of fuel injectors or believe that they only need cleaning after long intervals. They may not realize that even slight clogging of the injector can severely impact the vehicle's performance. The principle of fuel injectors in electronically fuel-injected cars: A fuel injector is essentially a precision solenoid valve. When the solenoid coil is energized, it generates suction, lifting the needle valve to open the injection hole. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a fine mist that promotes complete combustion.

What are the symptoms of a clogged fuel injector?

The symptoms of a clogged fuel injector include: 1. Engine shaking; 2. Unstable idle; 3. Reduced vehicle power and performance, such as unresponsive throttle or uneven acceleration; 4. Increased engine noise; 5. Slight misfiring sensation when upshifting at low RPM; 6. Higher fuel consumption; 7. Failed exhaust emissions. The common causes of fuel injector clogging are carbon deposits accumulating on the injector or impurities in the gasoline blocking the injector pathways. Gasoline inherently contains gums and impurities. Additionally, unstable components in gasoline can react under certain temperatures, forming sticky gum and resin-like substances. Coupled with urban traffic congestion, where cars often operate at low speeds or idle, these conditions further promote the formation and accumulation of such deposits.

What Causes a Car to Overheat?

The causes of car overheating: 1. Insufficient engine coolant; 2. Water pump failure, worn or loose drive belt; 3. Thermostat main valve fails to open or opens too late; 4. Louvers cannot fully open; 5. Dirty, damaged radiator fins or clogged radiator cooling tubes; 6. Scale buildup in the water jacket and distribution pipes. If the engine suddenly overheats during operation, it may be due to a broken fan drive belt, the water pump shaft and impeller disengaging, leaks in the cooling system (such as aging or ruptured hoses), or the thermostat main valve falling off. Generally, there are many reasons for engine overheating, and it is recommended that car owners visit a repair shop for inspection and maintenance. Regardless of the cause, overheating can affect driving safety.

What is the general fuel tank capacity of a car in liters?

Generally, the fuel tank capacity of small cars ranges from 35 to 45 liters, while that of medium-sized cars ranges from 55 to 75 liters. After filling up the tank, the car can usually travel about 500 kilometers. Depending on the engine displacement, cars with higher fuel consumption have larger fuel tanks, while those with lower fuel consumption have smaller ones. During the actual refueling process, the amount of fuel may exceed the calibrated volume. This is because the fuel tank capacity marked by car manufacturers is measured from the bottom of the tank to the safety level, and there is still some space from the safety level to the tank opening. This space ensures that the fuel in the tank can expand when the temperature rises without overflowing the tank's safety space. If the fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. If the car owner wants to know the remaining fuel level in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it indicates that the fuel is running low, and when it is near F, it means the fuel level is sufficient.
