What is the difference in fuel consumption between diesel and petrol?
However, diesel fuel is denser than petrol and contains about 15\% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre). A fuel consumption of 1 litre per 100km corresponds to approximately 26.5g CO2/km for diesel and 23g CO2/km for petrol, depending on the exact composition of the fuel.
What is the allowed NOx limit as per BS VI norms?
Motor vehicles
| Fuel Type | Pollutant Gases | BS6 (BSVI) |
|---|---|---|
| Petroleum Distillate Vehicle | Nitrogen Oxide (NOx) Limit | 60 mg |
| Particulate Matter (PM) Limit | 4.5 mg/km | |
| Diesel Fuel Vehicle | Nitrogen Oxide (NOx) Limit | 80 mg |
| Particulate Matter (PM) Limit | 4.5 mg/km |
What is the Euro 6 emissions standard?
Euro 6 is the name given to a set of limits for harmful exhaust emissions produced by virtually any vehicle powered by petrol or diesel engines – this includes hybrid cars, too, because they also use a petrol or diesel engine under the bonnet alongside their electrical elements.
What’s more efficient diesel or petrol?
Diesel is more dense than petrol and contains about 15\% more energy by volume. Diesel engines are still far more efficient than petrol engines at converting fuel to mechanical energy. In fact, including the energy advantage of the fuel itself, diesels are up to 40\% more efficient at doing that.
Is diesel more fuel efficient than petrol?
Diesels are more fuel efficient than petrol engines and emit less CO2, which makes them better for the environment. Diesels produce considerably more torque (pulling power) than their petrol counterparts, which makes them good engines for towing or carrying heavy loads – ie: seven occupants – on a regular basis.
Which engine is more powerful diesel or petrol?
Apart from the fact that diesel engines are more powerful than petrol engines, they also have higher torque, and hence they give a smoother drive. In petrol engines, the power developed is low due to the compression ratio, whereas in diesel engines, the power is more.
Which engine has more life diesel or petrol?
Diesel engines do last longer than petrol ones. Diesel is a light oil and when burned and used as fuel by the vehicle it lubricates the parts of the engine. This prolongs the life of the engine. While diesel engines typically last longer they are more costly to repair.
What is the major difference between BS IV and BS VI norms?
Compared to the BS4, the BS6 fuel has less sulphur and NOx. While the content of sulphur in BS4 fuel is 50ppm, it is five times lower in the BS6 fuel, which is at 10ppm. As for the nitrogen oxide, the permitted level has been reduced by 70\% and 25\% for diesel and petrol engines, respectively.
What are BS VI norms?
As per BS-VI emission norms, petrol vehicles will have to effect a 25\% reduction in their NOx, or nitrogen oxide emissions. Diesel engines will have to reduce their HC+NOx (hydro carbon + nitrogen oxides) by 43\%, their NOx levels by 68\% and particulate matter levels by 82\%.
What’s the difference between Euro 5 and Euro 6?
Euro 6. The Euro 6 standard imposes a further, significant reduction in NOx emissions from diesel engines (a 67\% reduction compared to Euro 5) and establishes similar standards for petrol and diesel.
What are different emission standards?
Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. Different regions and countries have different standards for vehicle emissions.
What is the difference between on-road price of petrol and diesel cars?
The difference in the on-road price of petrol and diesel car variants will be even more. This is because the cost of registration for the diesel car is more than that of the Petrol car. The difference is about 1 to 3\% depending on the cost of the vehicle and the State where it is purchased. 2.
How can we settle the petrol vs Diesel debate?
To simply put it we can settle the petrol vs diesel debate by breaking down the factors affecting your decision while choosing a car. Price Difference – A diesel variant tends to be significantly more (varies with each car manufacturer) expensive than its corresponding petrol avatar.
What is the price difference between petrol and diesel Tata Altroz?
As evident, the up-front price difference between the petrol and diesel Tata Altroz cars is as much as ₹1.61 lakhs, in favour of the petrol variant. The diesel variants of many cars command a higher premium over their petrol counterparts.
Should you buy a petrol or diesel car in India?
Owning a petrol car has always been equated with fun and Diesel with that of the economy. In India, quite often the price is the deal breaker whereas there is a number of factors to be considered while making the choice between the two variants. The difference between both the variants is more than just fun and economy.
