Auto Service: Why You Need to Maintain Your Car

Welcome to my blog. My name is Ken. One day, I was driving home from work when the engine in my car failed. While I waited for the recovery truck to arrive, I realised I didn’t have a clue what went on underneath the bonnet of my car. I signed up for an auto service course at my local community college, so I could gain the skills I needed to properly maintain my car and repair it if something when wrong while I was on the road. I wanted to start a blog to pass on these skills to other people so that they can look after their automobiles.

How to Improve the Performance of Your Vehicle's Diesel Engine


A diesel engine is typically known for being very strong and very fuel-efficient, as diesel engines convert heat to energy so that they run on more than just fuel alone. However, you may want to improve the performance of your diesel engine if you're towing heavier loads or need more pickup when you accelerate. Note a few ways you can improve the engine's performance without having to actually swap it out for something larger and more powerful overall.

Digital technology

Your vehicle's engine, fuel pump, oxygen sensors, and even parts of its exhaust are all controlled by a computer, which reads how the engine is functioning and then tells those pumps, sensors, and other parts what to do. There is digital technology that you can purchase and add to your vehicle's computer that will enhance its performance, by delivering more fuel or oxygen or pulling out more emissions from the engine itself. This technology can be programmed to ensure the vehicle has more pickup or works to provide more torque to the engine, which means more towing ability. A computer electrician or dealership can usually note the best technology for what you need from your vehicle and also install this technology for you.

More responsive fuel pump

Air is compressed in a diesel engine so that it becomes warm, and the engine can use that heat for power, as said above. A diesel engine will leave more air in the engine for this combustion, and reduce the amount of fuel pumped in, using that air for power. While this can be very fuel efficient, a larger or more responsive fuel pump can mean adding more fuel along with that reserved air, for more pickup when you accelerate. This may not help the vehicle's fuel efficiency, but it can increase its performance on demand.

Common rail compressor

A diesel engine will compress fuel as well as air to generate heat to be used for power; this compression is done through what is called a common rail system. This common rail system delivers fuel to each fuel injector, and some fuel is left over during this process. Being stored in the common rail allows that fuel to be compressed and heated. A modified common rail system can mean heating fuel faster, and being able to heat larger portions of fuel at once. In turn, there is more heat available to be used for power and your vehicle has better fuel efficiency and more torque or towing capacity.
