How to Deal with Excessive Exhaust Gas from a Car Engine?

Methods for handling abnormally excessive exhaust gas: If the exhaust gas is abnormally excessive, the solution is to take the car to a repair shop for inspection and maintenance. Car owners should promptly visit a repair shop for a check-up to prevent more serious faults. Common causes of excessive exhaust gas formation: 1. Incorrect adjustment of fuel injection timing: If the fuel injection timing is too late, the fuel cannot be completely burned, resulting in the emission of large amounts of black smoke. 2. Excessive gap between the cylinder and piston: Too much engine oil enters the cylinder, especially during splash lubrication, where a significant amount of oil seeps into the cylinder. 3. High-temperature gas from the cylinder leaks into the oil pan: This causes the engine oil to deteriorate, become contaminated, and thin, affecting lubrication efficiency and leading to excessive exhaust gas. 4. Severe wear of piston rings or cylinder liners: This results in poor sealing between the piston and cylinder liner, ultimately causing severe exhaust gas emission from the car's side breather, insufficient power in diesel engines, and possibly blue smoke emission.

How to Obtain the Environmental Protection Label?

Automobile environmental protection labels can be obtained at the vehicle management office. The owner needs to bring the vehicle registration certificate, the motor vehicle registration certificate, and their own ID card. The specific steps are as follows: 1. Submit the relevant documents at the issuance window of the vehicle management office; 2. The vehicle management office will review the documents; 3. Upon successful review, the vehicle management office will issue and print the classification label; 4. The applicant fills out the registration form; 5. The applicant receives the label and retrieves their valid documents; 6. The automobile environmental protection label is a classification label issued by the state for motor vehicle emission standards. There are two main categories, yellow and green, which are reviewed and issued based on the vehicle type and emission standards. The purpose is to meet the needs of energy-saving and emission reduction inspections and regular environmental protection checks for vehicles.

What is the difference between the left and right fuel filler openings?

The differences between the left and right fuel filler openings are as follows: 1. Balancing vehicle weight: Some car manufacturers pay close attention to the weight distribution of the vehicle body. Since the driver's weight is a fixed load inside the car, as long as the vehicle is driven on the driver's side, it will bear the driver's weight. To achieve a balanced effect, the fuel tank is placed on the opposite side. 2. Safety considerations: For vehicles that drive on the right side of the road, the fuel filler opening is designed on the right side, which is opposite to the driver's seat. This avoids vehicles passing behind the fuel attendant, thereby protecting the safety of the fuel attendant. 3. Driving direction designation: The position of the fuel filler opening and the driver's seat is generally designed diagonally. This means that the design of the fuel filler opening is directly related to whether the vehicle is driven on the left or right side of the road in different countries.

What Are the Hazards of Leaving a Car Unused for a Long Time?

Here are the hazards of leaving a car unused for a long time: 1. Accelerated engine wear: When a vehicle remains parked for an extended period, the lubricating oil film on the surfaces of the engine cylinders and pistons can deteriorate due to exposure to oxygen and other corrosive acidic and alkaline components in the air. This forms a gummy substance that loses its lubricating properties. Upon restarting the engine, dry or semi-dry friction occurs between the cylinders and pistons, accelerating component wear. Additionally, the starting resistance significantly increases, making it difficult to start the engine. 2. Tire deformation: When a car is parked, its weight is borne by the parts of the four tires in contact with the ground, causing these contact areas to compress and deform. The longer the car remains unused, the harder it is for the deformed areas to recover, altering the mass distribution around the tires and resulting in uneven rolling radii. This imbalance can cause body vibrations during high-speed driving, affecting ride comfort, accelerating tire wear, and introducing safety risks.

What Does All-Wheel Steering System Mean?

All-wheel steering system, also known as four-wheel steering system, refers to the rear wheels having similar steering functions as the front wheels. They can not only steer in the same direction as the front wheels but also in the opposite direction. Additional information: I. Main functions of all-wheel steering system: 1. Improve the operational stability of the vehicle during high-speed driving or under lateral wind conditions. 2. Enhance the vehicle's responsiveness to steering inputs across the entire speed range. 3. Improve maneuverability at low speeds and reduce the turning radius of the vehicle, enhancing mobility. II. Classification of all-wheel steering systems: 1. Based on the relationship between the deflection angle of front and rear wheels and vehicle speed, they can be divided into two types: angle-sensing type and speed-sensing type. 2. According to the power form of the wheel deflection actuator, they can be categorized into three types: hydraulic four-wheel steering system, mechanical-hydraulic four-wheel steering system, and electronically controlled four-wheel steering system.

Are the engines of the Hongqi H5 and the new Besturn B70 the same?

The engines of the Hongqi H5 and the new Besturn B70 are not the same. The Besturn B70 offers a choice between a 2.0-liter naturally aspirated engine and a 1.8-liter turbocharged engine, while the Hongqi H5 is only equipped with a 1.8-liter turbocharged engine. In terms of power, the 1.8-liter turbocharged engine in the Besturn B70 is tuned to deliver more power than the 1.8-liter turbocharged engine in the Hongqi H5. Relevant information about car engines is as follows: 1. Introduction: A car engine is the device that provides power to a car, acting as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental friendliness. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2. Classification: Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid types, among others.
