Improving the Lifespan of a Diesel Engine: A Guide for Students Attending Automotive School

Diesel engines are becoming a more popular option for vehicle buyers. When properly maintained, these engines are more durable and are likely to have a longer lifespan than regular gas powered engines. In essence, diesel engines are similar to gas powered engines. Both are internal combustion engines, which operate by converting the chemical energy in fuel into mechanical energy for a vehicle. Mechanical energy is the force that moves the pistons up and down within an engine’s cylinders, creating the motion that powers a vehicle. 

The difference lies in the form of combustions that occur. In a gas powered engine, combustion is created when fuel is mixed with air, then compressed and ignited by a spark plug. However, in a diesel engine, the air is compressed first and fuel is injected after, allowing the fuel to ignite to move the pistons.

If you’re interested in a career as an automotive mechanic, you’ll be helping drivers to maintain their diesel engines. When following these tips, a powerful diesel engine will last for thousands of kilometres, helping drivers to avoid expensive repairs. Read on to discover how to improve the longevity of a diesel engine!

Those in Auto Careers Should Make Sure to Change the Oil and Filters Frequently

In order to ensure that a diesel engine lasts as long as possible, it’s important to regularly change the engine’s oil and filters. An engine’s oil is important to reduce friction in between an engine’s moving components, and over time, this oil can become contaminated with debris, carbon, and bits of metal, negatively affecting its efficiency. Additionally, an engine’s oil filters will become clogged over time as debris and impurities build up within a fuel system. In order to avoid damage to fuel pumps and injectors, automotive school students should inform drivers to change their oil and oil filters every 8000 kilometres.

Give a Diesel Engine Some Time to Warm Up

Diesel engines will operate more efficiently when they are allowed to adequately warm up before a vehicle moves. Drivers should be advised to wait ten seconds to start driving after turning on their vehicle, especially in colder weather. Waiting allows the oil pump to properly lubricate the engine, helping it to run smoothly and ensuring that there are no leaks when the engine’s components expand with warmth.

Avoid Using Performance Products on a Diesel Engine

Today there are many companies that claim their products will enhance the performance of a vehicle. However, these products may in fact reduce the longevity of a diesel engine, even if their manufacturers market them as upgrades. Products such as performance injectors, chips, and FASS fuel pumps are supposed to make an engine work more efficiently, but a well-maintained diesel engine doesn’t need these enhancements to operate well. Professionals in auto careers can caution drivers with diesel engines to stay away from products like these and opt for routine maintenance instead.

Don’t Use the Full Tank of Fuel

While some drivers might be tempted to drive for as long as possible before refueling, this habit can negatively impact the longevity of a diesel engine. When a fuel tank is empty, debris and impurities can build up over time and infiltrate the fuel supply systems. In order to ensure that dirt doesn’t accumulate, drivers should fill their tank up when the fuel indicator shows that there’s a quarter of a tank of fuel left. 

Perform Regular Maintenance

Regular maintenance and preventative measures are the easiest way that drivers can prevent damage to their diesel engine and ensure that it lasts as long as possible. Drivers should take their vehicle to an automotive mechanic whenever their check engine light turns on or they suspect a leak. Additionally, it’s important for drivers to familiarize themselves with their vehicle’s maintenance manual. When a driver knows when to take their diesel engine in for maintenance, they’ll be able to keep their engine running for many years to come.
