Recently, the Ministry of Industry and Information Technology publicly solicited opinions on two mandatory national standards, namely "Evaluation Methods and Indicators for Fuel Consumption of Passenger Cars" and "Energy Consumption Limits for Electric Vehicles Part 1: Passenger Cars" (draft for comments).

The algorithm for the target fuel consumption of passenger car models is as follows:

For passenger cars with three or fewer rows of seats, the fuel consumption target value of the vehicle model should be calculated according to equations (1) to (3), and the calculation result should be rounded to two decimal places:

If the curb weight of the vehicle CM is ≤ 1090, then T=2.57 (1)

If 1090<CM ≤ 2510, then T=0.0015 × (CM-1580)+3.3... (2)

If CM>2510, then T=4.70 (3)

In the formula:

T - Target fuel consumption of the vehicle model, in liters per hundred kilometers (L/100 km);

CM - curb weight of the vehicle, measured in kilograms (kg).

According to the new regulations, for vehicles with a total weight of ≤ 1.09 tons, the fuel consumption per 100 kilometers is within 2.57 liters; For vehicles weighing between 1.09 tons and 2.51 tons, the fuel consumption per 100 kilometers is within 4.7 liters; For vehicles with a total weight greater than 2.51 tons, the fuel consumption gauge per 100 kilometers is 4.7L. The target value of fuel consumption for passenger cars has put forward higher fuel economy requirements for fuel vehicles, which will inevitably lead to more energy and cost for various automobile manufacturers to improve fuel economy.

Guangzhou Zeer Testing Technology Co., Ltd. has been committed to providing the best testing products and technical solutions for the automotive testing field worldwide. For testing the fuel economy of automobiles, we recommend the GREGORY brand fuel consumption meter from Germany, which is exquisitely crafted. This device is suitable for basic fuels such as gasoline, diesel, biofuels, and alcohol, and is used in motorcycles, passenger cars, buses, trucks, special purpose vehicles, and ships.

The testing equipment suitable for passenger car fuel consumption is S8005C lightweight high-precision fuel consumption meter+SCU8005D display screen. If you need to simultaneously consider speed and distance signals, you can use Racelogic's VBOX4 or Speed Sensor.

If you have further requirements for automatic report generation for testing and data analysis, the newly designed micro TAARE F1 monitor with integrated multiple functions is more suitable for you. It provides a complete solution for comprehensive fuel consumption measurement based on national standards such as "Chinese National Standards" (JT/T 719-2016 and JT/T 711-2016).
