Difference between BSIV & BSVI Engine: BS4, BS6 Performance

 To regulate emissions from cars and two wheels, the Indian government has enacted laws known as the Bharat Stage Emission Standards (BSES). The Central Government has mandated that all car manufacturers, both with two-wheeled and four-wheeled vehicles, should only produce, sell and register BS6 (BSVI) vehicles from 1 April 2020. In this article, you will learn about the BS4 vs BS6 engine, the major differences in engine performance. new BS6.

What is BS4 (BSIV)?

Before we understand the release of BS6 or BS6 compatible, let's understand the current terms of BS4 (BSIV), engine, operation, and its importance.

The BSES, an organization that controls emissions from all types of vehicles in the country, introduced the first pollution guidelines with the name ‘India 2000’ in the year 2000. BS2 and BS3 were introduced in 2005 and 2010, and the BS4 protocols came into effect in 2017 with strict issuance rates or procedures.

Among the rules set by the governing body, pollution-related changes include tailpipe removal, Electronic Control Unit (ECU), temperature control, etc. The most notable change is AHO (Automatic Headlamp On), which is one of the procedures under the BS4 which deals with the safety of new exit standards.

What is BS6 (BSVI)?

The governing body, the Bharat Stage Emission Standards (BSES), regulates the emission of pollutants from vehicles traveling in the country. The Central Pollution Control Board under the Department of Environment, Forestry, and Climate Change sets standards for vehicle pollution control in India.

The first exit or standard rate, introduced in the year 2000, was known as ‘India 2000’, and later, BS2 and BS3 were introduced in 2005 and 2010, respectively. While the first three release procedures were announced periodically, the BS4 was introduced in 2017, after a seven-year gap.

The BS6 emission rate is the sixth iteration of the emission rate and by comparison, it is a major leap in terms of reducing emissions compared to the BS4 emissions. This is because BS5 (BSV) has been skipped in an effort to go to better extraction procedures.

Differences between BS4 (BSIV) and BS6 (BSVI):

Both BSIV and BSVI are emission systems that set the most permissible levels of contamination from a vehicle or dual tire discharge. Compared to BS4 emission levels, BS6 is stronger. While manufacturers are using this change to update their vehicles with new features and safety standards, major or major changes are reflected in the strict permissible methods of release.

Pollution Practices (BS4 Vs. BS6):

In order to clean up the area and address the growing problems of global warming, the Indian government has quickly promoted BS6 pollution practices to April 1, 2020. Thus, the transition from BS4 to BS6 instead of BS5 to -BS6. Below are the differences between the pollution practices between BSIV and BSVI:

BSVI or BS6 is a measure of the emission rate or condition in reducing pollution levels compared to BSIV or BS4 standards. Both are high-emission systems that put complete pollution on a car’s exhaust.

While BS4 release standards allow the vehicle to emit more than 80 mg/km of NO2 (nitrogen oxides), BS6 release standards have been reduced to 60 mg/km. The Particulate Matter (PM) of petrol vehicles is limited to 4.5 mg/km in the BS6 state.

Below the BS6 rating, the pollution level is significantly reduced. While the average NOx emanating from diesel cars on the BS4 is 250 mg/km, it is reduced to 80 mg/km in BS6 emission systems. HC + NOx has been reduced from 300mg / km in BS4 to 170mg / km, while PM levels have been reduced from 25mg / km to 4.5mg / km.

The BS6 emission rate is not only for cars but also for fuel. Sulfur and nitrogen oxide plays an important role in fuel and diesel. Compared to BS4, BS6 fuel has less sulfur and NOx. While the sulfur content in BS4 oil is 50ppm, it is five times lower than BS6 fuel, which is 10ppm. In the case of nitrogen oxide, the permissible level is reduced by 70% and 25% in diesel and petrol engines, respectively.

From 1 April 2020, when the normal BS6 process begins, BS6 petrol will be refined from all the country's petrol pumps from the same date onwards. You can use BS6 fuel in BS4 cars.

With proper lubrication inside the engine, sulfur plays an important role; but, with BS6 fuel, sulfur is lower compared to BS4 fuel. These are referred to as additives that act as lubricating agents.

With BSVI procedures, Selective Catalytic Reduction (SCR) and Diesel Particulate Filter (DPF) are included to check the BS6 vehicle emission levels; however, this was not part of the release process set out in BS4.

Real Driving Emission (RDE) has been introduced in BS6 procedures to ensure that car exit is measured in real-time. This was not part of the BS4 process.

An addition to BS6 procedures is the Onboard Diagnostic (OD) which is not authorized for BS4 procedures.

A BS6 vehicle using BS4 fuel will not comply with the required emission standards due to high standards. Therefore, the BS6 vehicle should use only BS6 fuel to achieve the desired emission levels.
