What is the difference between a diesel mechanic and a petrol mechanic? And how does electrical engineering differ from electronical engineering?  These are some of the questions that may pop up when you’re considering a career in engineering. Read on to ensure that you choose the right course for you.


Differences between petrol mechanics and diesel mechanics

So you know that you want to become a motor mechanic, but do you know which type of mechanic you want to be? Although there are many similarities between petrol mechanics and diesel mechanics, there are some significant differences too. This is because petrol and diesel engines operate differently from each other, meaning that different mechanical skills are required to work on them.


As the name suggests, petrol mechanics are technicians who work with vehicles that are fueled by petrol. This means that their job will be mostly focused on fixing the engines and other components of smaller vehicles such as passenger cars, as many of these run on petrol.


Diesel mechanics work with vehicles that operate on diesel. The vast majority of trucks, buses, farm vehicles and industrial vehicles run on diesel, so these larger vehicles are what diesel mechanics will mainly work with.


Difference between petrol and diesel mechanic qualifications

Oxbridge Academy offers N1 – N3 Motor Mechanic qualifications in both petrol and diesel. Both fields of study include modules in Mathematics, Engineering Science and Engineering Drawings, as these cover the knowledge and skills needed to work with all engine types. The main difference is that the Motor Mechanic – Petrol qualifications include modules on Motor Trade Theory, while the Motor Mechanic – Diesel qualifications include modules on Diesel Trade Theory. These modules will equip you with the specific skills and knowledge related to each engine type.


After completing your N3 studies, you will be equipped to take your trade test and start looking for work as a mechanic in your chosen field.


Difference between electrical and electronical engineering

Put simply, the term “electrical” refers to anything that has to do with electricity. The term “electronical” (which is more widely known as electronic) is more specialised, referring to a type of electrical device. Electronic devices are more advanced than simple electrical devices such as fans or toasters. They are able to manipulate electrical currents to produce useful results, and can assign meaning to data. Computers and cameras are examples of electronic devices.


Electrical engineers will work mostly with the large-scale production and distribution of electrical power. They may, for example, be tasked with designing the circuits for a large building, or ensuring that a power station runs efficiently. Electrical engineers usually need a degree, but a national qualification in electrical engineering can prepare you for work as an electrician or electrical technician.


Meanwhile, electronics engineers work on researching and developing electronic devices, which could range from computers, cameras and cellphones, to satellites, radars and communications systems and many more. With a national qualification in this field, you will be prepared to work as something like an electronics technician, fixing issues with electronic devices.


Differences between electrical and electronical engineering qualifications

The N1 – N3 qualifications in both these fields are very similar, including modules in Mathematics, Engineering Science and Electrical Trade Theory. However, since electrical engineering professionals work with larger circuits, Engineering Drawings is included as a subject in these courses. Meanwhile, the electronical engineering qualifications include modules in Industrial Electronics, which will give students the specific knowledge and skills needed to work with electronic devices.


We hope that after reading this, you have a clearer idea of the right engineering path for you!
