What is the difference between the national three pumps and the national second pumps?

National 2 is a large pump direct injection, does not pick oil, if the mouth is broken, it is easy to repair and cheap, and it is not fuel-saving. National 3 is electrically controlled to inject oil, pick oil, the mouth is broken and it is not easy to repair, the price is expensive, fuel-saving. Because the national 2 engine emission does not meet the standard, the country will stop producing the country 2 engine, the country 2 is technically mature, and the country 3 is technology Advanced.

The most obvious thing is that the exhaust gas emission of the country 3 is more environmentally friendly than the country 2. It is mainly manifested in the engine oil supply system. The traditional (national second) diesel engine adopts the large pump oil supply method, while the national third adopts high-pressure common rail or egr technology and monomer pump technology. The common rail or monomer pump technology of the national diesel engine is called electric injection technology.

Different fuel and different structures. Fuel is different: the large pump provides high-pressure fuel, and the small pump provides low-pressure fuel. Different structures: the structure of large pumps is more complex, while the structure of small pumps is relatively simple.

The difference between the real national third and national second: the oil nozzle injection method has been changed from pressure injection to electronically controlled injection, that is, the national third is the electronically controlled high-voltage common rail mode.

Fuel economy: Guosan Electric Injection uses advanced injection technology to better control the amount of fuel injection, so that the fuel can be used more fully. In this way, the engine can achieve higher efficiency and reduce fuel consumption under the same workload.

Ha ha, let me tell you the easiest way. The diesel engine of Guo Er has an injection pump (large pump) and an injector (oil head). And the diesel engine of Guosan is an electric injection system.

Which one is better for the engine of the second and the third country

The internal structure of the third engine is improved on the basis of the second engine, and the cost of the third engine is much higher than that of the second engine. From July 1, 2008, new cars are only allowed to cars with national three emission standards. National second emission standard vehicles are not allowed to be certified at the DMV, and national second vehicles that have been certified continue to drive on the road.

The difference between the national third engine and the national second engine is the level of harmful substances emitted by the engine exhaust. The national third engine is lower than that of the national second engine. Distinguishing the difference between the engine from the structure of the engine, the fuel supply system of the national third engine and the national second engine are different, and the emission of harmful substances in the engine exhaust is also different.

The difference between MotoII and Moto3 is that Moto3 is more environmentally friendly than Moto2.Major domestic engine manufacturers have begun to develop their own EGR engines to meet the national third emission standards and meet market demand. The EGR engine is the engine that transitions from the second country to the third country. The real third national engine is a high-pressure common rail engine.

Xinchang 490 engine g2 is the national emission

1. Depending on the engine model, the 490 national third engine generally has 92 horsepower and a displacement of 7: the diesel engine is an engine that burns diesel to obtain energy release.

2. Kilometers. According to the query of Sina Automobile, it can be seen that the Guosi 490 light truck can run about 100 kilometers. The Guosi 490 light truck is usually equipped with a high-performance Yunnai 490 engine, and its maximum power and torque can support the vehicle to reach a speed of 100 kilometers per hour.

3. Generally, national four and five are high-pressure common-rail electric injection engines. The national five aerobic sensor, the national fourth does not. The engine uses fuel, and the electric motor uses electricity. The engine converts chemical energy into mechanical energy. The electric motor converts electrical energy into mechanical energy. The most essential difference between the engine and the electric motor: the engine---converts other energy into electrical energy.

4. The advantages of diesel engine are large torque and good economic performance. The working process of diesel engines has many similarities with that of gasoline engines; each working cycle also goes through four strokes: intake, compression, work and exhaust.

5. [Pacific Automobile Network] You need to know how much horsepower the 490 machine has, and you also need to know the specific model of the engine. 490 is not the engine model. The national third engine of the domestic GM 490 is generally 92 horsepower and 7 displacement. According to the engine marking code, 4 is the cylinder measurement, which means that the engine is four cylinders.

6. The national four full-firewood 490 engine can run more than 100,000 kilometers. 70 kilowatts cloud 490 engine weight 230 kg, power 50 to 70, speed 3200 rings, the engine quality can withstand tossing and turning on good roads and bad roads, and it can run more than 100,000 kilometers.

Penalty Standards for Selling National Second Engine Machinery

If you violate the law, you will be fined not less than 5,000 yuan and less than 20,000 yuan. It is forbidden to use non-mechanic vehicles below National II (including National II). The use of non-road mobile mechanical vehicles below National II (including National II) is prohibited. The use is illegal, and a fine of not less than 5,000 yuan and not more than 20,000 yuan shall be imposed in accordance with relevant laws and regulations.

Illegal. The exhaust emission of the national second tractor is not qualified, the vehicle inspection fails, and the sale of the national second tractor is illegal. Tractor (tractor) is a self-propelled power machine used to tow and drive operating machinery to complete various mobile operations.

It is not illegal to buy and sell disassembled parts and engines if the seller has the qualification to recycle scrapped motor vehicles;It is illegal to operate privately without qualifications. It is not illegal to buy and sell regular car parts.
