In very simple terms, higher horsepower translates to a higher top speed and a faster car. Conversely, a higher torque figure translates to more power at a lower RPM. When this is taken into consideration, diesel engines are the more powerful of the two.
Why petrol engine has more power?
A petrol engine has a shorter stroke which allows it to be revved more and put out more power. A diesel engine, on the other hand, has a longer stroke since it needs more compression to burn. This makes it rev less but put out a lot of torque for the same engine size.
Which engine gives more power diesel or petrol?
Diesel engines have always been more fuel efficient, durable and delivered more hauling power (torque) than gasolines. Typically, they contain less toxic pollutants but they did (in the past) have higher quantities of carbon (soot) in their exhaust than gasoline engines.
What car engine has the most horsepower?
These Are The Most Powerful Engines Ever Fitted In Production…
- 10 Most Powerful 16-Cylinder Engine – Bugatti Chiron Super Sport 1578hp. …
- 9 Most Powerful V12 Engine – Lamborghini Essenza SCV12 – 818hp. …
- 8 Most Powerful V10 engine – Dodge Viper ACR – 645hp. …
- 7 Most Powerful V8 Engines – SSC Tuatara – 1750hp.
Which engine produces more power for same compression ratio?
Compression Ratio: Why Diesel Engines are More Efficient than Gasoline Engines. Compression ratio plays as large a role in fuel efficiency as any other engine combustion factor. Diesel engines are between 25 percent and 35 percent more fuel efficient than gasoline engines of comparable size.
How long do petrol engines last?
It’s normal for your car’s gasoline engine to run for around 200,000 miles before it needs a serious overhaul, or you need a new vehicle. But diesel engines can continuously run for an impressive 1,000,000-1,500,000 miles before needing any major work.
Which fuel type car is best?
While petrol cars give good initial power, diesel cars provide higher performance in higher gears. On the other hand, diesel cars provide a higher fuel efficiency in comparison with petrol cars. This means that if you have to drive short distances within the city, a petrol car would make much more sense.
Is petrol car good for long drive?
If you want to keep a car for long and drive more than 80-100km a day, diesel can be a valid option. Otherwise, if your running is quite less and you don’t prefer keeping a car for more than 3-4 years, go for petrol.
Is V12 better than V8?
A V8 is an engine with a V-shaped cylinder block and eight cylinders. … V8 engines are smaller than V12 engines, making them a more efficient choice when space in a vehicle is limited. V8 engines also offer better fuel economy over V12 engines as they consume less gas due to having fewer cylinders than a V12.
