Diesel vs Petrol engines

Diesel vs Petrol Engines Blog


Means of mobility have gone through astounding transitions to be the way they are now. But no matter how the new wave of innovations shifts the design features your car will always be requiring fuel to function the way it is manufactured to. Since many automobile manufacturers are moving to new and efficient hybrid and electric vehicles (EVs), general consumers are still finding it unusual to acclimatize to the new mobility infrastructure. Generally, consumers prefer vehicles that have either diesel or petrol engines as the maintenance cost is relatively low than that of ultra-modern hybrid and electric vehicles. 


Petrol and diesel are the two most common engines that are standard in every automobile model. Since Kia always stays ahead in terms of technology and comfort controls, the global Kia car line-up gives you the freedom to choose from petrol, diesel, hybrid and electric engines. The feature may vary in different regions but you get to experience a standard level of quality and utility in every Kia. Currently, Kia Pakistan is offering vehicles with petrol engines in Kia Sportage, Kia Carnival, Kia Sorento, Kia Picanto and Kia Stonic. Here is how petrol engines differ from diesel engines and which engine should you prefer given the pros and cons that come with each.  



Petrol Engine 



All Kia cars in Pakistan come with built-in petrol engines. Petrol engines are also known as gasoline engines and were first invented in 1876 in Europe. This is an internal combustion engine in which air and fuel are mixed before compression. An electric spark is then used for ignition in which chemical energy is converted into thermal energy. Petrol engines are preferred over their counterparts as the maintenance services are readily available in case of any car trouble.   



How do petrol engines work? 



Here is a step-by-step breakdown of how petrol engines generally work in your car.


Step 1. Petrol and air are mixed together in the cylinder.

Step 2. The crankshaft then compresses the mixture of petrol and air.  

Step 3. The piston is forced down by igniting a spark in the mixture. 

Step 4. The exhaust valve then releases the gas out. 



Diesel Engine



The diesel engine is an internal combustion engine and is commonly used in trucks and heavy vehicles. In these engines, fuel is injected once the compressed air becomes very hot. Diesel engines were first developed in 1893 in Germany and were mainly used in trains and heavy trucks. Known as a compression-ignition engine, the heat of the compressed air helps the diesel engine reach the ignition temperature so that your car may head down the road you want.  



How do diesel engines work?   



Here is a brief process that will help you understand how diesel engines work in your car.

Step 1. The engine piston goes down and air comes into the cylinder.

Step 2. The engine piston goes up and compresses the air to heat up. 

Step 3. Diesel is then added to the cylinder with air. 

Step 4. The ignition temperature burns the fuel and the smoke goes out the exhaust valve. 



Diesel vs Petrol Engine



Both diesel and petrol are fossil fuels but the functionality of both fuel engines differ. Below are the major differences that make these two engines offer varying driving experiences. 



Diesel vs Petrol Engine- Which one should you choose? 



If your drive time is mostly spent on highways and long routes, the diesel engine is the best pick for you since it requires 15%- 20% less fuel than the petrol engine. The reason behind this significant fuel difference is their low-end torque which is not the same when it comes to petrol engines. But petrol engines offer a low-cost efficiency as compared to heavy vehicles since it is more expensive than the former.  



Diesel vs Petrol Engines- Which goes the extra mile? 



Diesel engines are more rugged in design based on their utility and off-road features and therefore last longer. Petrol on the other hand works as a cleaning agent, washing away oil from engine parts that result in a shorter life span of engine. Diesel engine lubricates the engine parts and therefore offer an increased lifespan of a vehicle’s engine.  



Diesel vs Petrol Engines- Pros and cons 



Diesel engines are more fuel efficient than petrol engines due to less carbon emission in the environment. These engines provide more towing capacity and therefore, are ideal for moving heavy loads. Since diesel prices are relatively less fluctuating than petrol prices, diesel engines are also cost-efficient. 


But on the contrary, petrol engines are easier to maintain since the service cost is low than diesel engines. Even unleaded petrol is less expensive than diesel fuel saving you fuel average as well as car maintenance costs.




Whether you choose to drive a diesel engine car or a petrol one, the pros and cons come naturally with the design. You need to analyze whether buying the petrol or diesel engine type will match your driving style or not. Kia recommends choosing diesel engines for long-route travelling but if you are not concerned with the miles petrol engine is your best bet. Kia Lucky Motors offers petrol-driven engines in the current line-up which you can purchase by visiting Kia Motors Site any time. Globally you will find trims and variants under both engine types as well as electric vehicles to choose from. Since petrol (gasoline) engines are more efficient in terms of fuel usage, service and maintenance cost, buying petrol engine cars is going is easy on the pocket and gives you less trouble in the long run.
