What are the new regulations for 5-seater vehicle annual inspections in 2021?

5-seater vehicle annual inspection new regulations for 2021 are as follows: Within 6 years: 7-9 seat non-operational small and mini passenger vehicles (excluding vans) are included in the exemption range, exempt from on-site inspection within 6 years, only requiring application for inspection marks every two years. More than 6 years but less than 10 years: The inspection cycle for vehicles more than 6 years but less than 10 years is relaxed from annual inspection to biennial inspection, meaning private vehicles only need on-site inspection twice within 10 years, specifically in the 6th and 8th years. More than 10 years: For private vehicles more than 10 years old, the original inspection cycle still applies, i.e., annual inspection for 10-15 years, and semi-annual inspection for vehicles more than 15 years old.

How many liters of fuel can a 60-liter fuel tank hold?

A 60-liter fuel tank can hold up to 75 liters. The fuel tank is a container in a vehicle for storing fuel, specifically designed to hold hydraulic oil or fluid in a hydraulic system. Fuel tanks can be categorized into two types: open tanks and closed tanks. The fuel tank must have sufficient capacity. Below is an introduction to gasoline grades: 90-octane gasoline: Suitable for gasoline-powered vehicles with an engine compression ratio below 8.5. 92-octane gasoline: Suitable for gasoline-powered vehicles with an engine compression ratio between 8.6 and 9.9. 95-octane gasoline: Suitable for gasoline-powered vehicles with an engine compression ratio between 10.0 and 11.5. 98-octane gasoline: Suitable for gasoline-powered vehicles with an engine compression ratio above 11.6.

What are the penalties for a 5-seat private car carrying 8 people under the new traffic regulations?

A 5-seat private car carrying 8 people is already considered overloading. According to the relevant provisions of the new Road Traffic Safety Law, driving with more than 20% of the approved number of passengers will result in a 12-point deduction. For private cars, overloading by just one person already exceeds 20%. A 5-seat private car carrying 8 people constitutes overloading by more than 20%. The following are the hazards of vehicle overloading: Increased risk of rollover: The more passengers are overloaded, the more the vehicle's center of gravity will shift, especially when turning, making the vehicle more prone to rollover. Weakened braking performance: Inertia is related to the mass of an object. When braking, the vehicle relies on resistance to stop. The more overloaded the vehicle is, the greater its inertia will be, making it harder to stop than usual. Tire blowout: Overloading causes the vehicle's tires to operate under excessive load continuously, increasing tire pressure and temperature, which can easily lead to tire blowouts. Worsened accidents: Under normal circumstances, every member in the car has corresponding safety belts, seats, and other equipment, but overloading means not everyone has these. In the event of an accident, situations that could have been avoided may now be unavoidable.

How Many Spark Plugs Should Be Replaced at Once?

Automobile spark plugs should be replaced four at a time, meaning all of them should be changed. Theoretically, even if you replace just one with the same brand and model, the discharge gap and resistance of the new and old spark plugs will differ. Not replacing all of them can lead to issues such as engine shaking, difficulty in acceleration, and increased fuel consumption. This is because differences among spark plugs cause variations in ignition timing and energy, resulting in an imbalance in power among the four cylinders. Currently, the common electrode materials on the market include copper, nickel alloy, platinum, and iridium. The electrical conductivity of these metals increases from left to right, while the voltage required for ignition decreases from left to right. Therefore, precious metal spark plugs place less load on the engine and are beneficial for reducing fuel consumption.

60 mph in 4th or 5th gear?

Using 5th gear is better because it is more fuel-efficient than 4th gear when driving at 60 km/h. At 60 km/h, the engine speed in 4th gear is around 2000 RPM, while in 5th gear, it is around 1500 RPM. Due to the higher gear ratio in 4th gear, the engine output torque is lower compared to driving in 5th gear. Here are some additional gear-shifting tips: Shift at the right time: Change gears according to the speed of the car. Downshift based on actual conditions: Sometimes while driving, you may notice the car shaking slightly, indicating that the engine is operating under low-speed, high-load conditions. In such cases, immediately downshift by one or two gears. Coordinate the clutch and throttle properly: When shifting gears, ensure the clutch and throttle are well-coordinated. Press the clutch pedal fully, then release the throttle pedal, and quickly shift to the appropriate gear. After shifting, release your hand immediately and avoid keeping it on the gear lever (commonly known as the gear stick) for too long, as this can easily damage the gear lever.
