The three types of regeneration are Active, Recovery, and Forced. If you own a diesel engine, you should know the differences between them, and select the right one for your vehicle. Regeneration is crucial to the engine’s performance, and can save you money on fuel. Find out more about each.
Active regeneration
Active regeneration is a process where the exhaust system of diesel engines is cleared of soot. The regeneration process may occur every day, based on the engine’s work cycle and the amount of soot it has built up over time. It can take up to half an hour. If the vehicle is stopped for too long, the regeneration process might be disrupted. Diesel engine spares regeneration
Active regeneration involves increasing the temperature of the exhaust gas to stimulate the oxidation process of soot in the exhaust. To increase the temperature of exhaust gas this process utilizes fuel combustion energy from the engine. The heat is then transferred to the exhaust stream and is used to burn the soot that has been accumulated in the DPF. Active regeneration methods are not yet available for all diesel engines.
A yellow warning light will flash in the event that the regeneration process is disrupted. This indicates high exhaust temperature. When the engine temperature is to normal the regeneration process will cease. The operator must ensure that the engine has enough fuel to properly regenerate. To ensure that regeneration starts immediately, he must follow the InfoCenter instructions. The vehicle must be turned off when regeneration is enabled. The temperature of the coolant should be at or below 140 degrees F.
Passive regeneration is automated, whereas active regeneration is initiated by the operator. Passive regeneration happens naturally, while active regeneration requires the engine to be active. Passive regeneration happens when the exhaust temperature of the diesel engine is 350 degrees Celsius, which is equivalent to 662 degrees Fahrenheit. In certain instances, the exhaust temperature is not sufficient to initiate regeneration, which could cause problems.
Recovery regen
The active regeneration technique is a procedure through which the engine ECU adjusts some parameters and increases the temperature of the exhaust. The catalyst reacts with the extra fuel and burns off the soot that has accumulated in the DPF. This is also known as parker regeneration. It should not be employed in dangerous areas, like those that have low-hanging branches and burning combustibles.
Regeneration frequency depends on many factors including the type of engine used and the load requirements. It may not be necessary for the vehicle to run the cycle daily if it’s designed for light loads. This case, it may be necessary to build an engine load bank. This could double the cost of the engine. The operator must also be involved in the process of regeneration. The process could take between 20 and 60 minutes and can consume as much as half the gallon of fuel. When the engine is regenerated, a slight whistling sound may occur however, this is completely normal.
Regeneration of diesel engine parts for marine use services are becoming more popular as a substitute for parts exchange. The marine environment can be extremely harsh on engine parts and a failure of one or more of them can compromise the security of the vessel. For this reason, a skilled team of marine engineers and mechanics should be employed to carry out the procedure.
Forced regen
Forcible regeneration is a typical practice for truck maintenance. While it is essential to resolve an issue and take the vehicle to a service center, it is essential that fleets are aware of how to make these processes as efficient and effective as possible. Here are some things to remember when you force-renew the engine of a diesel.
For first, forced regens are time-consuming, often taking 30-60 minutes. The process also generates substantial amounts of heat, rendering the engine inoperable until it cools. This inconvenient downtime, combined with the expense of labor and the need of a service area, could result in lost hours. Additionally, it could affect fleets’ timely delivery rates.
If your engine stops running after forcing regeneration, it’s most likely that the DPF is faulty. If this happens, it may be required to clean or replace the DPF. Other instances could indicate a problem in another aspect of the aftertreatment process. In these cases, forced regen might not be the best option.
Forced regeneration is a solution to many common issues which include the DPF filter that is not full or is not working properly. A blocked DPF can cause a car to stop driving or make it difficult to drive. Fortunately, if the DPF isn’t working properly, the DPF can be cleaned and replaced to keep your diesel engine running smoothly.
