What is the difference between calibration and bench test

1. In short, calibration is the process of optimizing the control parameters of each control unit.The bench test refers to the inspection of the quality of gasoline, oil, diesel and gear oil by simulating the operation process of automobile engines. It is generally a large-scale project. In this case, the test data of some instruments and equipment required will cooperate with each other.

2. Different definitions have different experimental categories. Bench test refers to placing the equipment or components to be tested on a specific test bench for various tests to verify its performance and reliability; type test refers to the conformity test of a certain category of product to verify its compliance with the technical performance and quality requirements set by the standard.

3. Bench test refers to testing the quality of gasoline, oil, diesel, gear oil, etc. by simulating the operation process of automobile engines.

4. Platform calibration engineer. Work volume.The whole vehicle calibration engineer has a large workload and high working pressure, and the platform calibration engineer has a small workload and small working pressure, which is a very good job. Salary.

What are the brands of automobile electric drive platform power tester

BAIC manufactures Beijing off-road Great Wall tank and Fike Jeep BYD F brand猛S and look up the two major brands ranking and the standard basis of fuel-powered off-road vehicle brands It's the same, so the next step is to know the drive system that may be applied. The most likely application scheme starting from BAIC Manufacturing is "double engine range increase".

The third technology product released this time, Haozhi Electric Drive, will provide a strong "heart" and strong "muscles" for the models of Nezha Automobile.

Such as Chevrolet Bolt and Ford MustangMachE.These brands of new energy vehicles all adopt advanced battery technology and electric drive systems, which can provide higher energy efficiency and longer range. In addition, the U.S. government has also introduced a series of policies to support the development of new energy vehicles, such as providing tax incentives and subsidies.

BAFANG/Bafang: The main business of Bafang Electric (Suzhou) Co., Ltd. is the research and development, production, sales and technical services of electric bicycle motors and supporting electrical systems. The company's main products are central motors, hub motors and complete sets of electrical systems.

What are the automotive testing instruments? Engine performance testing and diagnostic instruments and equipment: engine bench test equipment, engine power test equipment, engine tachometer, cylinder pressure gauge, cylinder leakage detector, engine thermometer, etc.

Domestic electric vehicle brands include NIO Automobile, Weima Automobile, BYD, Tengsi and other brands. Electric vehicle BEV refers to the domestic electric vehicle brand that uses on-board power supply as power and drives wheels with motors to drive, which meets the requirements of road traffic safety regulations. NIO is a global intelligent electric vehicle Dynamic automobile brand, in November 2014.

Introduction to Dongfeng General Assembly Factory, Engine Factory, Frame Factory

1. Dongfeng Automobile Company Casting Factory No. 2, the largest modern ductile iron production plant in China, mainly produces Dongfeng series automobile chassis parts The casting professional factory.

2. A factory covers an area of 1.81 million square meters and has a research and development center and packageIt includes nine process production lines such as stamping, welding, synthetic resin, painting, engine casting, mechanical processing, engine assembly and automobile general assembly.

3. Dongfeng 49 Factory, known as Dongfeng Automobile Company Engine Factory, is located at the foot of Wudang Mountain in Shiyan City, Hubei Province, China, on the banks of the Han River, with convenient transportation and a beautiful environment.

4. The factory is the general assembly factory. Opposite the 3rd Brigade of Traffic Police. Dongfeng Automobile General Assembly Plant Flowing Production Line: The general assembly factory has twelve production workshops such as assembly, adjustment, delivery, cushioning, charging, etc. Three bridge chain plate chain combined vehicle assembly lines and the corresponding three adjustment workshops.

5. Hubei Shiyan Dongfeng Automobile Factory: The factory belongs to the Parts Division of Dongfeng Automobile Co., Ltd. The old factory is located on Dongyue Road, Zhangwan, and the new factory is in the industrial park. The factoryThe factory has been built for more than 50 years. It specializes in the production of automobile chassis, with strong technical strength and strong production capacity.

6. As the main base for research and development and production of Dongfeng Passenger Car Company, the Wuhan factory is located at No. 1969 Dongfeng Avenue, Wuhan Economic and Technological Development Zone, Wuhan City, Hubei Province, covering an area of 1,200 mu. It is planned at one time and implemented in two phases.

Engine emission test system [Discussion on the delay of emission component analysis of the engine test system...

The engine emission pollutant test system generally includes three parts: engine operating platform, engine exhaust sampling system and emission component analysis system. The delay of the discharge test system is mainly determined by the sampling system.

The places that need to be checked are: the spark plugs of the engine and the cylinder line. Test the engine fuel pressure system. Check whether the fuel nozzles of each cylinder of the engine are normal. Check the fuel pump and fuel pump line of the vehicle. It is also necessary to check the pressure in the engine cylinder.

Exhaust problem;Post-oxygen sensor, ternary catalyst, exhaust camshaft and shaft tile. The most common one is that the engine fault light turns on due to the ternary catalyst failure.

Toxicity analysis based on BaPeq shows that small-size particulate matter shows stronger quivisant toxicity, and the burning of biodiesel can significantly reduce the equieval toxicity and the concentration of the quieval toxicity of particulate emissions.

It will affect fuel consumption. In the long run, there will be too much carbon accumulation due to poor combustion effect, and there will be no adverse effects that will directly lead to engine damage in the short term. The failure of the engine emission system will affect the safety of the car during driving and reduce the service life of the engine.

What are the auto parts testing equipment?

1. Car detection equipmentIncluding: automobile fault computer diagnostic instrument, automobile computer engine comprehensive analyzer, electric injection cleaning test bench, computer wheel balancer, computer four-wheel positioner, brake test bench, side slip test bench, automobile headlight detector, automatic refrigerant processor, air conditioning leak detector, etc.

2. Test analysis equipment: test line, exhaust gas analyzer, decoder, illuminance meter, oscilloscope, refrigerant doser, smoke meter, endoscope, etc. Automobile inspection equipment: automobile speedometer inspection table; vehicle speed list; automobile side slip inspection table: automobile scale tester; automobile brake inspection table.

3. Infrared thermal imager: The infrared thermal imager can determine whether there are scratches by detecting the heat changes on the surface of the parts. High-resolution camera: Use a high-resolution camera to take pictures of the surface of parts, and use image processing software to analyze and identify scratches.
