Most of us worry over the question of which car to buy – a diesel or a petrol car. This has been one of the most frequently asked questions among buyers buying their first car in Long Island. The performance of diesel and petrol cars may have differed considerably in the past. But with time and technology, both the cars show almost the same level of performance.
One of the main differences between a diesel and a petrol car is the way they use their Air Fuel Ratio (AFR). In a petrol car, the engine breathes in the ratio and plugs it in the combustion chamber of the car and then sets it up with the help of a spark plug. However, in the case of a diesel engine this can be done without the help of a spark plug by simply crushing the ratio until it discharges.
A petrol car can make more trips than a diesel car with the same amount of gas or diesel through any given time period. Diesel means more torque and petrol means more speed. Both the engines, however, deliver the same amount of horsepower.
A diesel engine is more energy efficient as it ignites the ratio by squeezing it. Petrol engines depend more on the air of AFR whereas diesel engines run based on fuel usage. Though the present petrol car engines have better fuel efficiency, diesel car engines can show 15% extra fuel efficiency.
Diesel engines are costlier than the petrol ones. It might take a considerable amount of time to recover from the fuel usage savings depending on the amount of driving you do. However, the petrol cars are sure to eat up more fuel than the diesel counterparts, which is why they seem to be costlier on the long run.
Ultimately, there is quite a thin line between petrol and diesel engines. What you should be thinking about is the future – with hybrid cars running on green fuels!
