Can a car operate normally after removing the catalytic converter?

A car cannot operate normally after removing the catalytic converter. Reasons why it cannot operate normally: Oxygen sensors are installed both before and after the catalytic converter. The oxygen content in the front is higher than that in the rear. After removing the catalytic converter, the oxygen sensor will detect an excessively high oxygen concentration, indicating that the filtration effect has not been achieved. The electronic control unit will then interpret this as the air-fuel mixture being too lean, leading to an increase in fuel injection, which makes the mixture too rich and increases the car's fuel consumption. Catalytic Converter: It is a device used in cars to purify exhaust gases. It enhances the activity of exhaust components, converting some harmful substances in the exhaust into harmless substances that are expelled from the vehicle, thereby reducing atmospheric pollution. Since it does not participate in the reaction itself, it neither gets consumed nor ages. However, it is often damaged during daily use, mainly in three forms: catalytic converter poisoning failure, catalytic converter clogging, and catalytic converter breakage.

Why Does the Brake Make Abnormal Noises When Turning?

Reasons for abnormal brake noises when turning: poor quality brake pads, foreign objects entering the brake disc, severe wear of the brake disc, severe wear of the brake pads, rust on the brake disc, etc. The following is a detailed analysis: Poor quality brake pads: If the brake pads installed are not provided by a reputable manufacturer or are of inferior quality purchased by the owner themselves, the overly hard material can cause a squeaking sound when braking and also damage the brake disc. Therefore, it is advisable to replace the brake pads with genuine ones at an authorized 4S shop. Foreign objects entering the brake disc: When driving on complex road conditions, the wheels can easily fling stones or other foreign objects. Unlike drum brakes, disc brakes can trap stones between the brake pads and the brake disc, causing abnormal noises when braking. Severe wear of the brake disc: Sometimes, the brake disc can be directly scratched by foreign objects or hit by other objects, leaving pits on the surface. When the brake pads rub against an uneven brake disc, it can also produce squeaking noises. Severe wear of the brake pads: After driving for a certain period, the brake pads will thin out due to prolonged friction. Overly thin brake pads not only reduce braking effectiveness but also cause abnormal noises due to the hardening of the material. Rust on the brake disc: Years of exposure to wind and rain can cause the brake disc to rust. However, this situation is not a cause for concern, as stepping on the brakes a few times will wear off the rust layer on the brake disc.

Will driving with a detached intake pipe damage the engine?

Driving with a detached intake pipe will damage the engine. Reasons why it can damage the engine: The intake pipe is the manifold that connects the air filter to the carburetor. The intake manifold is the pipe that connects the bottom of the carburetor at the upper end to the intake valve of the cylinder block at the lower end. Without the intake pipe, issues such as vehicle shaking, insufficient engine power, and increased fuel consumption may occur. Intake pipe: Includes the main intake pipe and the branch intake pipes. In addition to power performance, the engine must also have good fuel economy and emission performance. In gasoline engines, the intake pipe must also consider issues such as fuel atomization, evaporation, distribution, and the utilization of pressure waves. In diesel engines, it is also required that the airflow forms an intake vortex in the cylinder through the intake port to improve mixture formation and combustion.

What is the wheelbase of a sedan?

Wheelbase of a sedan refers to the distance from the center of the front axle to the center of the rear axle. It is the distance between two vertical lines passing through the centers of adjacent wheels on the same side of the vehicle and perpendicular to the longitudinal symmetry plane of the vehicle. Classification of wheelbase: It is divided into fixed wheelbase, bogie wheelbase, and total wheelbase. Total wheelbase is the distance from the foremost axle to the rearmost axle, which is the main parameter affecting the "turntable length" of a train. Impact of wheelbase on a car: The length of the wheelbase greatly affects the comfort and handling stability of a sedan. Generally, the higher the sedan class, the longer the wheelbase. A larger wheelbase means a longer cabin length, more spacious seating space for passengers, better anti-pitch and anti-yaw performance. While a long wheelbase improves straight-line cruising stability, it reduces steering flexibility, increases turning radius, and worsens the car's maneuverability.

Should You Drive Fast or Slow Through Water on the Road?

Driving fast through water on the road is generally better. However, when facing waterlogged sections, you should adjust your speed flexibly based on the water depth. Reasons for driving fast through water: Before driving through water, you can first check the water depth and choose a shallow, slow-moving area to drive through quickly in one go. Driving too fast may cause stalling: First, after entering a waterlogged section, the car will churn up water and mud in the puddle, creating wave-like movements. If the speed is too high, water can easily splash onto pedestrians or vehicles in adjacent lanes, and in severe cases, it may obstruct others' vision and compromise driving safety. Second, if the water is too deep, splashed water may enter the engine's air intake, causing the car to stall. Driving too slowly may cause exhaust pipe backflow: Although the exhaust pipe has some thrust and can block water from entering when submerged, if the speed is too slow and the water is too deep, the exhaust pipe's thrust may not be sufficient to prevent water from flowing back into it. Therefore, while driving at a low speed through waterlogged sections, the speed should not be excessively slow.
