Can I Ignore the Engine Malfunction Light?

It is temporarily acceptable to ignore the illuminated engine malfunction light. This commonly referred to yellow engine malfunction light is also known as the fuel injection system fault light. As long as there are no noticeable abnormalities in engine power or sound, you can continue driving. This is because the ECU (Engine Control Unit) has a fault substitution program. Engine malfunction signal: The engine malfunction signal is issued by the ECU, which controls all electronic components of the engine, including electronic throttle, fuel injectors, alternator, fuel pump, etc., covering systems such as intake, exhaust, fuel, ignition, and timing. If the engine malfunction light comes on, you must visit a nearby repair shop for inspection. Coolant temperature gauge: First, check the coolant temperature gauge and oil pressure warning light. If these indicators show no warnings, the vehicle can still be driven, but you must pay attention to controlling the speed and promptly drive to a repair station for inspection.

Does the 6th Year Vehicle Inspection Require a Physical Test?

The sixth-year vehicle inspection requires a physical test. Assuming the vehicle meets the exemption conditions and the driving license inspection period is 2014, then during the six years from 2014 to 2019, it can enjoy two exemptions from physical testing, only needing to apply for an annual inspection sticker every two years. By the 6th year (i.e., 2019), the vehicle is no longer within the exemption range and will require a physical test, along with applying for the annual inspection sticker. Below are the vehicle inspection cycle regulations: 1. Operational passenger vehicles must be inspected once a year within 5 years; after 5 years, every 6 months. 2. Trucks and large or medium-sized non-operational passenger vehicles must be inspected once a year within 10 years; after 10 years, every 6 months. 3. Small and mini non-operational passenger vehicles must be inspected once every 2 years within 6 years; after 6 years, once a year; after 15 years, every 6 months.

How Does an Oxygen Sensor Work?

The basic working principle of an oxygen sensor is: under certain conditions, it utilizes the oxygen concentration difference between the inside and outside of the zirconia element to generate a potential difference. The greater the concentration difference, the larger the potential difference. The oxygen content in the atmosphere is 21%, while the exhaust gas from rich mixture combustion contains virtually no oxygen. The exhaust gas produced by lean mixture combustion or misfires contains more oxygen, but still significantly less than the oxygen content in the atmosphere. Additional information about oxygen sensors is as follows: 1. Under high temperature and the catalysis of platinum, the oxygen attached to the oxygen sensor is completely consumed, thus creating a voltage difference. A rich mixture outputs a voltage close to 1V, while a lean mixture outputs a voltage close to 0V. 2. Based on the voltage signal from the oxygen sensor, the air-fuel ratio is controlled to adjust the fuel injection pulse width. Therefore, the oxygen sensor is a key sensor for electronic fuel metering control.

What is the reason for the cancellation of the small car lottery application result?

The reasons for the cancellation of the small car lottery application result include: errors in the application information, changes in circumstances, or the desire to reapply after withdrawing the application, which requires submitting a new application. Applicants can log into the system, enter the user center, click on the "Application Form" in the configuration indicator function area, and then click on "Reapply" on the application form page, following the system prompts step by step. Alternatively, they can bring their valid ID card and a copy to the nearest district office for external services. Validity period of the lottery: After winning the lottery, the validity period is 6 months. If the indicator is not used within the validity period, it will become invalid. In such cases, the applicant will not be able to participate in the lottery for two years and must wait until after this period to reapply. Definition of the lottery: The lottery is a regulatory policy introduced by the state to curb excessive growth in car numbers and environmental pollution. It is a form of purchase restriction policy, where only eligible citizens can participate in the lottery.

How to Remove Anti-Theft Wheel Bolts?

Tire anti-theft bolts can be removed by following these steps: 1. Open the vehicle's toolbox; 2. Use a specialized wrench to remove the anti-theft bolts. The functions of tires are: 1. Transmit driving force, braking force, and steering force to enable vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging vehicle components. Tire maintenance methods include: 1. Regularly clean stones from tire treads; 2. Minimize exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Regularly inspect front wheel alignment; 6. Adopt careful driving habits, choose road surfaces wisely, avoid objects that may puncture or scratch tires, and steer clear of chemical spills that could corrode tires.

What Causes Increased Fuel Consumption After an Oil Change?

The reasons for increased fuel consumption after an oil change: The viscosity of the new oil is higher than before. For example, if the original oil viscosity was 5w-30 and the new oil viscosity is 5w-40, the increased viscosity leads to greater resistance, resulting in higher fuel consumption. Definition of fuel consumption: Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when driving a certain speed over 100 kilometers on the road. It is a theoretical indicator for vehicles. Calculation of actual fuel consumption: Fuel consumption per 100 kilometers = Volume of fuel consumed (liters) ÷ Distance traveled with that fuel (kilometers) × 100. For example, if a car consumes 4 liters of fuel to travel 50 kilometers, then the fuel consumption per 100 kilometers = 4 liters ÷ 50 kilometers × 100 = 8 liters/100 kilometers. The fuel consumption per 100 kilometers is not fixed; factors such as road conditions, load, temperature, and whether the air conditioning is on can all affect fuel consumption.
