What happens if the catalytic converter is removed from a car?

After removing the catalytic converter, issues such as insufficient backpressure and the illumination of the check engine light may occur. Here are the specific details: 1. Insufficient exhaust backpressure: After removal, due to the exhaust pipe becoming too unrestricted, there will be a condition known as insufficient exhaust backpressure at low RPMs. Because the engine has valve overlap, the exhaust becomes too unrestricted, causing the fresh intake air to be expelled along with the overlap, resulting in a loss of low-end torque in exchange for increased high-RPM horsepower. 2. Check engine light illumination: Most cars have an oxygen sensor located after the catalytic converter. After removing the catalytic converter, the monitored data will differ from the factory-set values, triggering the check engine light.

How to Apply for a Beijing Entry Permit for the First Time?

Offline application locations are outside the Sixth Ring Road, while online applications can be processed by downloading the Beijing Traffic Police APP and filling in the relevant information. Below is extended information about applying for a Beijing Entry Permit: 1. Notes: For the first application, you must drive to the location. Subsequent renewals of the Beijing Entry Permit do not require driving. The initial Beijing Entry Permit is valid for 7 days. If an extension is needed upon expiry, you can apply for a one-time 5-day valid Beijing Entry Permit at the Beijing Traffic Police branches or teams. 2. Required Documents: ID card, temporary residence permit, original copy of compulsory traffic insurance, driver's license, vehicle registration certificate, neighborhood safety committee filing form, and vehicle emission compliance certificate, with two copies of each.

What is the reason for the front of the car air conditioner not cooling while the rear is cooling?

If the front of the car air conditioner is not cooling while the rear is cooling, it may be due to a malfunction in the front air conditioner's blower, preventing it from cooling. Below is more information about car air conditioners: 1. Cooling Principle: When the car air conditioner is cooling, the compressor clutch engages, causing the engine to drive the compressor. The compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, cooling the evaporator. The cooled evaporator then cools the air blown by the blower. 2. Heating Principle: When the car air conditioner is heating, the engine's high-temperature coolant passes through the heater core. At the same time, the air blown by the blower also passes through the heater core, allowing the air conditioner vents to blow warm air.

How to Calculate the Costs of Car Installment Payments?

Installment payments consist of a down payment and subsequent repayments. Below are the specifics of car installment purchases: 1. Advantages: Long payment terms and a wide range of options. Dealers are highly enthusiastic, as in the current market environment for car enthusiasts, installment payments are seen by many dealers as an effective means to capture market share. 2. Payment methods: Bank consumer loans, loans from car manufacturers' financial companies, and financing leases, with the market mainly dominated by the 'Kaiyuan Auto' brand chain. 3. Pros and cons analysis: Pros—bank auto loans have higher interest rates but relatively lower repayment pressure, and multiple banks offer auto loans. Cons—the maximum installment amount is linked to the overdraft limit. For example, for most installment car purchases, the maximum amount is four times the overdraft limit. However, the installment limit is separate from the spending limit, meaning after purchasing a car in installments, the spending limit is not occupied and can still be used normally.

What Causes a Gasoline Engine Spark Plug Not to Fire?

Gasoline engine spark plugs may fail to fire due to damage or lack of electrical current. It is advisable to check whether the ignition wiring of the car engine is functioning properly. The spark plug is a crucial component of the gasoline engine ignition system. It introduces high voltage into the combustion chamber and generates a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. This creates a discharge channel between the gap, resulting in a 'breakdown' phenomenon. At this point, the gas forms a luminous body, known as a 'spark.' Along with thermal expansion, a 'snapping' sound is produced. The temperature of this electrical spark can reach 2000–3000°C, which is sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.

How to Repair Hard and Ineffective Brakes on a Focus?

Difficulty in pressing the brake pedal may be due to a leak or malfunction in the car's brake booster pump. 1. Possible causes: Regular maintenance of the brake system is essential during normal vehicle use. Common issues include excessive impurities in the brake master cylinder, poor sealing, leaks in the brake master or wheel cylinders, failure of the vacuum booster pump, or overloading. It is recommended to inspect the brake master cylinder and its bleeding condition; check if the brake fluid is sufficient; examine the brake fluid lines for leaks; and inspect the brake wheel cylinders, brake pads, and related components. 2. Solutions: If the brake fluid contains too much moisture, it can evaporate and vaporize under high temperatures (such as during summer when exposed to intense heat, the brake temperature rises with frequent use), forming vapor locks in the brake lines and causing sluggish braking. In this case, the brake fluid needs to be replaced.
