The secrets of the diesel engine that every driver should know
Discovering the secrets of the diesel engine can make a difference in the performance and longevity of your vehicle. From understanding how fuel burns at low revolutions to knowing the key components and best practices for maintenance, it is essential to optimize its operation. Here you will learn everything you need to drive efficiently and take care of your diesel engine.
The diesel engine is known for its efficiency and durability, characteristics that have made it popular among many drivers. However, to make the most of its advantages and ensure optimal performance, it is essential to understand certain crucial aspects. This article breaks down maintenance tips, efficient driving techniques, and details about the key components of modern diesel engines.
Characteristics of the diesel engine
The diesel engine is distinguished by its high torque at low revolutions, allowing for a more relaxed and efficient drive. This is achieved thanks to the way fuel is burned as it is admitted, thereby providing greater efficiency in converting fuel into energy.
Maintenance of the diesel engine
To ensure a long life for your diesel engine, there are some essential points that you should never overlook:
Never skip maintenance
Regular maintenance is crucial. Make sure to perform oil and filter changes as recommended by the manufacturer.
Do not turn off the engine abruptly
Avoid shutting off the engine suddenly, especially after a long journey. Allow the engine to cool a bit by driving at low revolutions before turning it off.
Never run the fuel tank to empty
It is important not to let the fuel tank run completely dry before refueling. This can help prevent impurities from the bottom of the tank from entering the injection system.
Choose the right moment to refuel
Do not refuel if the gas station has just received a delivery, as this can stir up sediment in the storage tanks and introduce impurities into your engine.
Key components of the diesel engine
Particulate filter
This component helps capture and burn the soot particles produced during combustion, thereby reducing harmful emissions.
EGR (Exhaust Gas Recirculation)
The EGR system recirculates a portion of the exhaust gases back into the engine, helping to reduce NOx emissions.
AdBlue system
AdBlue is a urea solution used to reduce nitrogen oxide (NOx) emissions through a selective catalytic reduction process.
Turbo
The turbo increases the amount of air entering the engine, improving efficiency and performance. Next-generation engines, such as the BMW with 4 turbos and 400 HP, are a clear example of this advanced technology.
Common Rail and injectors
The Common Rail system allows for high-pressure fuel injection, resulting in better combustion and efficiency. The injectors play a crucial role in this system, ensuring that the fuel is atomized correctly.
Efficient driving techniques
Use of engine brake
Instead of relying solely on the brakes, use the engine brake to reduce speed. This not only saves fuel but also decreases brake pad wear.
Know the clutch pedal
Familiarize yourself with the feel and travel of your vehicle’s clutch pedal. This will allow you to shift gears more efficiently with less wear.
Innovations and recommended models
Advances in diesel technology have allowed for the development of more efficient and less polluting engines. The incorporation, for example, of the hybrid GPL solution allows more polluting diesel vehicles to operate in low emission zones (LEZ). For more information on these innovations, visit this link.
Models like the BMW 525 tds (e39) or engines with 300 HP, are examples of vehicles that combine performance and efficiency.
For those interested in used models, options like those from Peugeot available here can be considered.
Diesel engines stand out for their high torque at low revolutions, making them a preferred option for those seeking efficiency and durability. However, to get the most out of a diesel engine, it is essential to know and apply certain care and techniques.
One of the keys is to never neglect maintenance. This includes regular oil changes, filters, and keeping the cooling system in good condition. A well-maintained engine not only runs better but also extends its lifespan. Moreover, it is vital not to turn off the engine suddenly after intensive use. This habit protects internal components like turbochargers, preventing damage from overheating.
Another crucial aspect is using the engine brake instead of traditional brakes. In modern diesel engines, this practice not only helps reduce fuel consumption, but also decreases brake wear. Additionally, it is essential not to run the fuel tank too low. Driving with extremely low fuel levels can damage the injection system, as impurities from the bottom of the tank can reach the injectors.
It is also important to consider the quality of the fuel. Avoiding refueling at poorly reputed gas stations can save you problems related to contaminated fuel. Another secret is to let the engine warm up a bit before starting to drive and allow it to cool down before turning it off, to ensure that all components function correctly and avoid unnecessary wear.
Finally, knowing the modern elements of a diesel engine, such as the particulate filter, the EGR valve, and the AdBlue system, allows the driver to perform better maintenance and more efficiently troubleshoot common problems. A well-cared-for diesel engine can offer superior performance and a prolonged lifespan, becoming a long-term investment for any driver.
