Embodiment 1

[0034]A method for measuring the fuel consumption of methanol vehicles. The first step is to prepare the test vehicle for measurement. The vehicle runs for 3000 kilometers, the tire pressure meets the technical requirements, the vehicle is in good condition, and M100 methanol fuel that meets the vehicle fuel methanol standard is filled. , the second step is to carry out preprocessing before the vehicle measurement, the vehicle enters the laboratory, simulates the working condition of the vehicle driving in the urban area once, and then simulates the driving condition of the vehicle driving in the suburbs twice. After running, the vehicle is placed in a room with a temperature of 20°C to 30°C to fully cool the lubricating oil and coolant of the engine until it reaches the room temperature within ±2°C, and the treatment period is 6h to 30h. The third step is the working condition test stage. The vehicle enters a special emission laboratory, and the driving wheel is placed on the ...

Embodiment 2

[0052] A method for measuring the fuel consumption of methanol automobiles. For methanol mixed fuel, methanol accounts for 85% of the total fuel, and gasoline accounts for 15% of the total fuel. When calculating the consumption in the fifth step,

Abstract

The invention relates to a fuel consumption measurement method, in particular to a method for measuring mixed fuel consumption of a methanol vehicle. The method comprises the steps of: after preprocessing the vehicle, simulating a comprehensive working condition for detecting, collecting tail gas and then directly detecting consumption of a mixed fuel by using a law of indestructibility of matter. The method has the advantages of simple detection process, no influence of temperature and volume changes to a detection process, and accuracy in measurement values, and solves the technical programof incapability of effectively detecting the fuel consumption of the mixed fuel of the methanol vehicle in the prior art.

Description

technical field [0001] The invention relates to a method for measuring fuel consumption, in particular to a method for measuring the mixed fuel consumption of methanol vehicles. Background technique [0002] With the development of industrial technology, automobiles have become an important means of transportation for people. At present, the fuel for automobiles includes liquid fuels such as gasoline, diesel oil, methanol, ethanol, and biodiesel, as well as gaseous fuels such as dimethyl ether, liquefied petroleum gas, compressed natural gas, liquefied natural gas, and hydrogen. Methanol is a liquid at room temperature, its storage and transportation methods are similar to those of gasoline and diesel, its thermal efficiency is high, and its physical and chemical properties meet the needs of automobile engines. Therefore, methanol is currently one of the most important alternative fuels for vehicles. Methanol is used as a vehicle fuel in various ways, including M100 methano...
