Why diesel cars are costlier than petrol?
It takes less refining to create diesel which explains its slightly lower cost. Also it is more oily and heavy than petrol for which it evaporates slowly (in fact diesel s boiling point is higher than water). This coupled with efficient engines gives diesel cars the tag of being more fuel efficient.
Which part is common between diesel and petrol?
4.6
SI engine (Petrol Engine) | CI engine (Diesel Engine) |
---|---|
A carburetor is used to atomize, vaporize and meter the correct amount of fuel according to the requirement. | Fuel injection pumps and atomizers are used to inject metered quantities of fuel at high pressure according to the requirement. |
Which of following option is correct when diesel is compared to petrol?
Solution(By Examveda Team) Per litre, diesel contains more energy than petrol and the vehicle’s engine combustion process is more efficient, adding up to higher fuel efficiency and lower CO2 emissions when using diesel.
What is similar between petrol and diesel?
Difference Between Petrol and Diesel Engine | |
---|---|
Diesel Engine | Petrol Engine |
Ignition is achieved with the help of the hot, compressed air. | Fuel is ignited with an electric spark |
High compression ratio | Relatively low compression ratio |
High power production | Relatively low amounts of power are produced in a Petrol engine |
What is the difference between petrol and diesel cars?
2. Petrol vs Diesel Mileage: The mileage of the diesel engine car is more than that of a Petrol engine. A diesel engine does not need a spark plug and thus has higher compression. It makes the diesel engine utilise more fuel as compared to a petrol engine.
What are the advantages of diesel engines?
A diesel engine does not need a spark plug and thus has higher compression. It makes the diesel engine utilise more fuel as compared to a petrol engine. The better mileage of a diesel engine makes it easy to cover the extra cost of the car paid initially, but with the increasing cost of cars, the time required to recover this cost has increased.
Why are diesel cars so bad for the environment?
There is an ethical issue here, too. Older diesel engines emit higher quantities of nitrogen oxides (NOx) and microscopic particulates, which linger in the air and cause respiratory problems – a particular issue in cities, where air quality is considerably worse than in the countryside.
Why does a diesel engine burn faster than a petrol engine?
Well, in this situation there are chances that engine. The fire point of diesel is greater than patrol and compression ratio of the diesel engine is also greater than petrol. At the end of the compression but unlike diesel, it burns immediately causing rapid burning of patrol. Due to
