There are three types of regeneration: Active, Recovery, or Forced. If you have diesel engines it is important to know the differences between them and select the right one for your vehicle. Regeneration is essential to the engine’s performance and could help you save money on fuel. Find out more about each one.
Active regeneration is a method in which the exhaust system of diesel engines is cleared of soot. The regeneration process can take place once or several times a day, depending on the engine’s duty cycle and the amount of soot that has accumulated over time. It could take up to half an hour. The regeneration process may be stopped if the vehicle has been stopped for a prolonged duration. Diesel engine spares regeneration
Active regeneration is the process of raising the temperature of exhaust gas to encourage soot burning. To raise exhaust gas temperature the process makes use of fuel combustion energy from the engine. The heat is then transferred to the exhaust stream, where it burns the soot that is in the DPF. Active regeneration methods are not yet available on all diesel engines.
A yellow warning light will light up in the event that the regeneration process is stopped. This is a sign of high exhaust temperature. Once the engine temperature returns back to normal the regeneration process will stop. Operators must make sure there is enough fuel to allow the engine to properly regenerate. To ensure that regeneration starts immediately, he must adhere to the InfoCenter instructions. When regeneration is enabled the vehicle must be idle and the coolant temperature should be at least 140degF.
Passive regeneration happens automatically but active regeneration has to be initiated by the driver. Passive regeneration occurs naturally, while active regeneration requires the engine to be active. Passive regeneration happens when the exhaust temperature for the diesel engine reaches 350° Celsius. This is equivalent to 662° Fahrenheit. In some cases it is possible that the exhaust temperature isn’t high enough to initiate regeneration, which can cause issues.
The active regeneration technique is a method by which the engine ECU adjusts some parameters and raises the temperature of exhaust. The catalyst reacts to the extra fuel and burns the soot from the DPF. This regeneration technique is called parker regeneration. However, it should not be used in situations that could be dangerous for instance, in areas with low-hanging branches or the presence of combustibles.
The frequency of regeneration varies on many factors such as the type of engine being used and its load requirements. If the vehicle is built for lighter loads, it might not be required to run the regeneration cycle on a daily basis. In this scenario, it might be necessary to purchase an engine load bank. This could double the engine’s cost. The operator should also be involved in the process of regeneration. The process can take between 20 to 60 minutes, and it can consume up to half the gallon of fuel. During regeneration, a slight whistling sound could be heard, but this is completely normal.
Marine diesel engine spares regeneration services are becoming increasingly popular as a substitute for parts exchange. Engine parts are susceptible to damage due to the harsh marine environment. Failure of one or more engine components can pose a threat to the security of the vessel. This is why a competent team of mechanics and marine engineers should be hired to perform the task.
Forced regeneration is a typical practice in truck maintenance. While it is important to fix an issue and bring the vehicle to a service centre however, it is crucial that fleets are aware of how to make these processes as efficient and effective as they can. There are some things to consider when force-regenerating a diesel engine.
For the first time forced regenerations can be long and time-consuming, taking between 30 and 60 minutes. The process also generates significant quantities of heat, which renders the engine unusable until it cools. This could result in lost hours due to the unplanned downtime and the costly cost of labor. Further, it may also affect fleets’ on-time delivery rates.
If you’ve noticed that your engine stopped working after forcing regeneration There’s a good chance it has a fault involving the DPF. If this happens, it may be required to clean or replace the DPF. Other instances could be a sign of a problem in another part of the process after treatment. In these instances forced regen might not be the best option.
Regeneration can be a solution to many common problems for example, a DPF filter that is too full or not working properly. A blocked DPF could result in an undriveable vehicle or the mode of limp. Fortunately when the DPF isn’t working properly it is possible that the DPF can be cleaned and replaced to keep your diesel engine in top shape.
