What are the exhaust emission standards for vehicle annual inspections?

Starting from May 1, 2019, China implemented new standards for motor vehicle exhaust emission testing. The new standards mainly include OBD (On-Board Diagnostics) inspections. If the vehicle's malfunction indicator light is on or faults are detected during inspection, exhaust emission testing cannot be conducted, resulting in failure to pass the annual inspection. Additionally, the new standards have stricter emission limits and added nitrogen oxide testing for diesel vehicles. The main changes in the new standards are: 1. Tightened pollutant emission limits with more stringent requirements. 2. Added OBD inspection requirements to examine the OBD functionality and fault alarm handling of certain existing vehicles. 3. Added NOx testing methods and limit requirements for diesel vehicles (implemented in November), addressing the lack of standards for NOx emissions from in-use diesel vehicles. 4. Standardized the procedures and items for emission testing, with regulations on visual inspections, OBD checks, pollutant emission testing, and reporting. 5. Standardized the content and time limits for data recording, storage, and documentation. 6. Added relevant requirements for newly registered vehicles, transfer registrations, and roadside inspections.

What are the three types of suspension in Wuling Hongguang?

Wuling Hongguang adopts a front MacPherson independent suspension and a rear semi-independent suspension with spiral spring link swing arm, which is also commonly used in many small cars. Traction Arm Suspension System: The traction arm suspension system is specifically designed for rear wheel suspension systems. European car models such as Peugeot, Citroën, and Opel prefer this type of suspension system. Multi-link Suspension System: The multi-link suspension system is further divided into a 5-link rear suspension and a 4-link front suspension system. As the name suggests, the 5-link rear suspension system includes five links: the control arm, rear positioning arm, upper arm, lower arm, and front positioning arm. Among these, the control arm can adjust the front wheel beam. 4-link Front Suspension System: Primarily used in luxury cars, this system cleverly separates traction force, braking force, and steering force through kinematic principles while providing the vehicle with precise steering control. The 4-link suspension system is commonly found in Audi A4, A6, and Chinese luxury cars.

What is the penalty for speeding between 10% and 20%?

Speeding between 10% and 20% results in a fine and 3 demerit points. Below are the specific details regarding road speed limits: 1. Penalty Regulations: Speeding within 10% of the road speed limit results in a warning without fines or demerit points; speeding between 10% and 20% incurs a fine and 3 demerit points; speeding between 20% and 50% incurs a fine and 6 demerit points; speeding over 50% results in a fine and 12 demerit points. 2. Speeding Percentage Calculation Formula: (Speed / Speed Limit - 1) * 100 calculates the speeding percentage. For example, if the speed limit is 70 km/h and the vehicle speed is 80 km/h, divide 80 by 70, subtract 1, and multiply by 100 to get 14.28, meaning 14% over the limit. If the speed limit is 60 km/h and the vehicle speed is 70 km/h, divide 70 by 60, subtract 1, and multiply by 100 to get 16, meaning 16% over the limit.

How many people can the Wuling Hongguang accommodate?

Wuling Hongguang can accommodate 8 people, with configurations available in 5-seat, 7-seat, and 8-seat variants. Body dimensions: The new Wuling Hongguang has a body length of 4420mm, width of 1685mm, and height of 1755mm (1770mm with roof rack). Compared to the older classic version, the length has been reduced by 20mm while the width has increased by 25mm. Interior dimensions: The maximum practical interior dimensions of the Wuling Hongguang are: length 2100mm, width 1400mm, and height 1310mm. The cargo space can reach 1750L by simply folding the rear seats, and can be expanded to 3050L by removing the rear seats and folding the middle row seats. The top trim features front seats with 8-way adjustable design, offering 190mm of fore-aft travel. The middle row seats come with independent armrests and can be adjusted for position and backrest angle, with 160mm of fore-aft travel.

What is the fuel tank capacity of the 2018 Geely Emgrand in liters?

The 2018 Geely Emgrand has a fuel tank capacity of 55 liters. Generally, small cars have a fuel tank capacity of 35-45 liters, while mid-size cars have a fuel tank capacity of around 55-75 liters. The following is an introduction to the fuel tank: Fuel tank capacity: Generally, small cars have a fuel tank capacity of 35-45 liters, while mid-size cars have a fuel tank capacity of around 55-75 liters. A full tank of fuel usually allows the car to travel approximately 500 kilometers. The size of the fuel tank depends on the car's displacement and fuel consumption—cars with higher fuel consumption have larger tanks, while those with lower fuel consumption have smaller tanks. The design of the fuel tank capacity generally allows for a range of 400-600 kilometers. Lighter cars with smaller displacements have correspondingly smaller fuel tank capacities, while heavier cars with larger displacements naturally have larger fuel tank capacities. However, the maximum range on a full tank is mostly between 400-600 kilometers. Fuel tank capacity measurement unit: Internationally, the standard unit for measuring fuel tank capacity is liters (L). Different countries also have their own standards for fuel tank capacities.

What is the fuel consumption of a 250cc motorcycle?

250cc motorcycles typically have an actual fuel consumption ranging from 2.5 to 3.2 liters per 100 kilometers. Additional details are as follows: 1. Introduction to Fuel Consumption: Fuel consumption refers to the amount of fuel consumed by a vehicle over a distance of 100km. The economic performance of a vehicle is primarily indicated by its fuel consumption, which is a crucial aspect of vehicle usability. Fuel consumption parameters include steady-speed fuel consumption and cycle fuel consumption. Steady-speed fuel consumption is a measure of fuel efficiency when a vehicle travels at a constant speed on good road conditions. Road cycle fuel consumption is determined by driving the vehicle on roads according to specified speed and time protocols in repeated cycles, also known as multi-condition road cycle fuel consumption. 2. Factors Affecting Fuel Consumption: Fuel consumption is influenced by the type of vehicle, number of cylinders, year of manufacture, driving habits, and road conditions. For example, a domestic single-cylinder 250cc or a Japanese V2 twin-cylinder 250cc motorcycle has a combined fuel consumption of about 3.5 liters per 100 kilometers. For an inline 4-cylinder 250cc motorcycle, such as the Hornet or CBR250, the combined fuel consumption is approximately 5 liters per 100 kilometers under normal driving conditions, and around 6 liters under aggressive driving.

Why does a Toyota vehicle automatically sound the alarm?

Toyota vehicle automatic alarm may be caused by unfastened seat belts, unclosed doors, abnormal low-pressure buzzing, or overheating water temperature. The specific reasons for Toyota vehicle automatic alarm are as follows: Unfastened seat belts: The driver did not fasten the seat belt after getting into the vehicle. Unclosed doors: When the vehicle is stationary, the door open signal triggers the indicator light to illuminate. During driving, if the door open signal is triggered, the indicator light stays on continuously, and the buzzer alarms. Abnormal low-pressure buzzing: (For air brake models) The low-pressure buzzer for air brakes keeps sounding. Under normal conditions, the pressure indicated on the pressure gauge should not be lower than 600 kPa. When the engine is running at 75% of the rated power speed, the indicated pressure on the pressure gauge should rise from zero to the starting pressure (400 kPa) within 4 minutes, and the low-pressure alarm buzzer should stop alarming. Overheating water temperature: The overheating water temperature alarm buzzer sounds intermittently, beeping for 0.5 seconds and pausing for 0.5 seconds. Note the priority: the low-pressure alarm buzzer sounds first, followed by the overheating water temperature alarm buzzer.
