Petrol vs Diesel cars
If someone wants to buy a car but is confused about which car is the best, diesel car or petrol car? there are so many things which should be considered before buying a new car such as mileage, insurance, engine capacity, maintains cost, average running and impact on the environment. It’s obviously a very tough decision someone has to make.
eZhire is here to help you to know about both cars in detail so that one can easily choose which one to buy without wasting more time on deciding.
The petrol engine obviously runs on petrol which is also called gasoline. Gasoline engine uses in many states. This engine is an internal combustion engine with spark-ignition which First invented in Europe in 1876, this engine saw many improvisations in later years. One can find in most of the petrol engines, the air and fuel are pre-mixed before the compression process. But, some of the modern petrol engines use cylinder-direct petrol injection. Here, the electronically controlled fuel injection does the pre-mixing except for small engines. Later, the spark plug is used to start the combustion.
The diesel engine is also known as a compression-ignition engine and runs on diesel. It is an internal combustion engine where only air is compressed. At the end of the compression stroke, the fuel is injected into the hot air. To initiate the ignition, the engine uses this heat of compression. During the ignition process, the fuel will be burnt which was injected into the combustion chamber. This engine was developed by Rudolf Diesel in 1893.
Types of Diesel Engine
There are two types of diesel engines- two-stroke and four-stroke. A two-stroke engine which is also called as the two-cycle engine is an internal combustion engine that is capable of completing a power cycle with two strokes and one crankshaft revolution. On the other hand, a four-stroke engine which is also called as the four-cycle engine is an internal combustion engine that completes a power cycle with the help of four separate strokes in two separate crankshaft revolutions and single thermodynamic cycle.
There are various other factors that one should consider first. Here we will mention some other factors as well.
There are many important factors while buying a new car, such as diesel car costs more as compared to petrol. For instance, if someone takes a car with a price of fewer than 15 lakhs, one can notice a difference in showroom price by 1 to 1.5 lakhs between diesel and petrol variant. As well as , the difference in the on-road price will be more. The main reason for difference in price is the cost of registration. The cost of registration for any diesel car is higher than a petrol car. The difference will be about 1 to 3% on this cost. Besides, this cost totally depends on the vehicle price as well as the state of purchase.
Comparatively diesel cars have more mileage. Since the diesel engine does not require any spark plug, it has a higher compression. This is the main reason for more fuel utilization than the petrol engine. As someone pays extra for buying a diesel car, the better the mileage covers this cost.
It is commonly known that a diesel engine is more powerful than a petrol engine and diesel engines also have a higher torque comparatively. This feature offers a smoother drive but keeps in mind that diesel cars lack a little in NVH (Noise Vibration and Harshness) levels. That is, the vibration, harshness, and noise in diesel cars are more compared to petrol engines. It is one of the issues that concern most of the drivers. If the noise is not a problem one should go with a diesel car. Otherwise, we recommend you to go with a petrol car.
It is one of the basic things to consider before choosing the car. Go for a diesel car only if your average monthly running is higher such as 1,500-1,700 km. Otherwise, buying a petrol variant which is available at a less price is the best option
Indeed the diesel cars also have a higher maintenance cost because this is the higher cost of the consumables used in diesel cars such as engine oil and spares. but , the used diesel cars have more value than a petrol one. However, the petrol engine has more life than the diesel engine. It’s definitely a personal choice whether resale value matters more than the life of an engine or vice versa.
Environmental effects are also an important factor, it is mandatory to give attention to this factor. Diesel emits a higher percentage of nitrogen oxides and particulate matter when compared to petrol. It is the reason why some people prefer petrol cars over diesel.
Petrol costs less at the pump than diesel but the running efficiency of petrol vehicles are less than diesel vehicles, so there is a need to refill the tank often. But if someone drives fewer than 12,000 miles a year, the lower cost of buying, maintaining, and fueling petrol cost will offset all those bills at the supermarket forecourt.
Insurance is one such factor which you cannot take for granted. If the price of the car is higher, then the premium for car insurance would be higher. And, this would be around 10 – 15 % higher for diesel cars when compared to petrol cars. It is mainly because of the additional cost involved in diesel engines such as the cost of replacement and repairs.
Petrol vehicle is the best option if someone drives fewer than 12,000 miles a year, mostly in local journeys or in city centres.
The conventional wisdom that long-distance drivers benefit from diesel engines still holds. But, better to keep in mind that it works both ways. If someone is driving primarily a diesel car for short trips, the engine stands to deteriorate quicker and require even more frequent services.
