Advantages Diesel Engines Have Over Petrol Engines

Spread the love

There are millions and millions of vehicles sold worldwide every year. There is a huge demand for vehicles. This is because of the ease of travel and transport. Vehicles make our lives easier. Even though all vehicles fulfil a certain requirement there are many things that set each vehicle apart. From the size of the vehicle to the weight and speed differs. Further vehicles run on different mechanisms. Each manufacturer has their style technology that they embed into their vehicles. Other than this there are vehicles that run on petrol, diesel and vehicles that are hybrid and electric. Hybrid vehicles and electric are quote new but petrol and diesel vehicles have been there for many decades.

Diesels engines used to be very dirty and loud. Further diesel engines made the whole vehicle vibrate. With today’s technological progress and efficiency this is no longer the case. Diesel engines are a very attractive purchase to consumers. Some people are unaware of the difference between a petrol and diesel engine. Here’s a list of difference between diesel and petrol engines.

The biggest difference is the way both engines work. Petrol is more volatile therefore it is mixed with air before being compressed by the piston and ignited. Diesel engines on the other hand compressors the air first and thereafter fuel is injected. Petrol engines use spark plugs while diesel engines use fuel injectors.


When it comes to torque diesel engines are more powerful. Diesel engines have higher compression ratio than a diesel engine therefore it gives more power. Due to this most trucks, tankers and Lorries use diesel engines. Similarly many vehicles such a Honda, Ford, Toyota and Nissan Patrol wreckers are diesel for the added power. More power is always important when driving on rough terrain and difficult landscape.

Fuel Consumption

Fuel Consumption is better in a diesel vehicle than a petrol vehicle. Diesel is much richer in energy and you will have to go to a fuel station much fewer times than a petrol vehicle. Diesel engines give much better mileage than a petrol engine. A 4×4 vehicle such as the Nissan 4×4 wreckers benefits a lot from being a diesel engine.

Holding the value
Diesel engines hold their value much longer than petrol vehicles.  This is a large advantage between petrol and diesel engines. Petrol engines fall faster in value than a diesel vehicle and after a few years will cost considerably less than their diesel counterpart. One of the reasons for this is the fuel efficiency that diesel vehicles have over petrol vehicles. This has always been the case and will continue to do so.
