    What is the difference between Petrol and Diesel Cars?

    What is the difference between petrol and diesel? For example, petrol engines tend to have more horsepower, but diesel has more torque. Why is this? Diesel also requires less maintenance as opposed to petrol. Why? Also can anyone explain how the diesel engine? He does not run on the spark plugs right? Help me guys!

    Many of us are confused when buying a new car as to which to go, a petrol or diesel car. Those who have used both in a moment of time or other have their own preferences in terms of driving experience. There was a time when diesel cars made fun of cases, due to its low performance, but times have changed and with advancing technology and the introduction of new CRDI engines, diesel cars are an attractive option for those who will buy a new car. There are still differences between the two types of cars, and here's a comparison that will keep you in good stead to pick one.
    Fuel is fired with the help of a spark plug in petrol cars, while diesel cars do not need a spark to ignite the fuel. Compressed air is the trick of diesel it burns when injected due to compression and temperature. The candles are meant only for petrol cars.
    The energy efficiency of gasoline vehicles is much lower compared to diesel vehicles. Diesel produces more energy per unit of fuel and that is why vehicles with a higher power, such as trucks and buses run on diesel only. The thermal efficiency of diesel makes it suitable for heavy vehicles.
    Modern cars are designed to obey his orders. Puts more pressure on the accelerator, the more fuel is injected into the engine to burn for more power. With gasoline, it is naturally do while in the case of diesel, there is a slight delay and you feel that you are not getting as much power as you need. But with the recent innovation called Common Rail Diesel Engine (CRDi) diesel cars are turbo and now it runs alongside the gasoline cars.
    Diesel vehicles have a couple more than petrol cars. This makes maneuvering a diesel car easier than the petrol engine when driving uphill and it takes less effort due to the higher torque generated.

    • Petrol cars are less fuel efficient
    • Petrol engine requires less maintenance
    • Petrol car has a higher pick up, but with CRDI, diesel has come close
    • There is less sound in Petrol cars than diesel cars
    • Both are made to last
    • New diesel cars are costly, but save in the long run with higher fuel efficiency
