  • Diesel Engine Wet Stacking: Causes, Consequences & Prevention

    Diesel Engine Wet Stacking: Causes, Consequences & Prevention
    2025/06/22
    Diesel Engine Wet Stacking: Causes, Consequences, and Prevention Introduction Diesel-powered generators are renowned for their reliability and fuel efficiency, outperforming gasoline, propane, and natural gas units in both longevity and operating costs. However, to deliver on that promise, they must be run under sufficient load. Operating a diesel generator “light” or idling for long periods leads to a phenomenon called wet stacking, sometimes nicknamed “engine slobber.” Left unchecked, wet stacking degrades performance, increases maintenance costs, and can even void the manufacturer’s warranty. In this post, you’ll learn: What wet stacking is, and why only diesel engines experience itThe root causes, from low-load operation to fuel-system faultsHow wet stacking damages cylinders, rings, injectors, oil, and exhaust systemsPractical prevention strategies, including correct sizing and load-bankingEarly-stage remediation techniques you can perform yourselfWhen to call in certified Perkins or Caterpillar techniciansWarranty implications and why prevention is the best protection What Is Wet Stacking? Definition:Wet stacking occurs when unburned fuel and heavy hydrocarbons accumulate in the exhaust system and cylinder walls of a diesel engine. Rather than fully combusting, extra fuel condenses into oily black sludge (“wet stack”) that drips from the exhaust or turbocharger housing. How to Recognize It: Visible Signs: Dark, oily deposits around the exhaust outlet or downpipe; black residue on nearby surfaces.Audible/Sensory Cues: A strong diesel smell after shutdown; popping or back-firing at startup.Engine Behaviour: Blue-gray smoke on acceleration; lower exhaust temperatures at idle. Primary Causes Low-Load Operation: Running below 30–60% of rated capacity prevents cylinders from reaching optimal combustion temperature.Oversized Units: Generators sized for peak demand but seldom loaded will chronically under-utilize capacity.Combustion Pressure & Sealing Issues: Low cylinder temperatures cause ring glazing, which reduces seal effectiveness and worsens incomplete combustion.Fuel-System Faults: Over-fueling: injection timing or metering set too rich.Worn or mis-set injectors: leaks or poor spray patterns.Incorrect air–fuel ratio: blocked air filters or intake restrictions. Environmental and Usage Factors: cold-weather idling, infrequent exercise under load, and moisture accumulation. Consequences & Damage Cylinder & Ring Glazing Glazing smooths out honing patterns on cylinder walls, preventing oil-control rings from wiping excess oil and leading to blow-by and accelerated wear. Injector & Valve Fouling Sludge deposits on injectors and valves disrupt spray patterns and airflow, impairing combustion and raising emissions. Oil Dilution & Corrosion Unburned fuel washes into the crankcase, diluting oil, lowering viscosity, and forming corrosive acids that damage bearings and camshafts. Exhaust & Turbocharger Impact Oily deposits in turbochargers and exhaust piping increase back-pressure, reduce efficiency, and clog after-treatment devices. Performance & Emissions Rough running, stalling, or hard startingHigher fuel consumption for the same powerFailed emissions systems risk regulatory non-compliance Prevention Strategies Regular Load-Banking: Frequency: at least monthlyProcedure: run at 30–75% load for 30–60 minutes to burn off deposits Proper Sizing: Select a generator whose typical load sits above 40% of capacity; consider paralleling smaller units if demand is intermittent.Consistent Real-World Operation: Utilize real loads (HVAC, pumps, lighting) rather than extended idle periods; simulate loads as necessary.Fuel Quality & Stabilization: Use ultra-low-sulphur diesel, keep tanks topped up, and add stabilizers for storage over 30 days.Routine Maintenance: Follow Perkins or Caterpillar recommended intervals for oil and filter changes, air filter replacements, injector and valve checks, and cooling system inspections. Modern Engine Considerations Advanced common-rail injection, charge-air cooling, and electronic controls reduce, but do not eliminate, the risk of wet stacking. Proper loading remains essential. Shorter, more frequent light-load tests for some applications.Quarterly complete load-bank tests for standby units with low real demand. Remediation of Early-Stage Wet Stacking Heavy-Load Run-Up: Operate at a load of≥ 75% for 1–2 hours; monitor smoke and exhaust temperatures.Visual Inspection: Check for reduced sludge at the exhaust and turbo housing; test the oil for fuel dilution.Repeat as Needed: Multiple cycles may be required to restore normal combustion. When to Call the Experts If symptoms persist, such as deep glazing, repeated oil dilution, or chronically low exhaust temperatures, schedule professional service. Certified Perkins or Caterpillar technicians can hone cylinders, replace rings, calibrate injectors, and rebuild turbos to minimize downtime and cost. Warranty ...

  • Perkins Engine Warranty – 6000 Hours!

    Perkins Engine Warranty – 6000 Hours!
    2025/06/17
    Episode Description

    Aurora Generators has teamed up with Perkins® to deliver an offer that redefines peace of mind for backup-power owners. In this episode, we break down how the new promotion upgrades every 10 kW and 13 kW Aurora diesel generator with FREE Perkins Platinum Protection—doubling engine coverage to four years or 6000 hours. You will hear why extending the standard 2-year/3 000-hour warranty matters for homes, farms, tele-sites, and off-grid cabins that cannot afford downtime.

    We start with the fundamentals: what makes a Perkins liquid-cooled diesel so different from gasoline, propane, or air-cooled units? Lower fuel burn (≈ approximately 0.5 gal/hr at 10 kW), rugged 20,000-hour life-to-overhaul, and whisper-quiet operation, thanks to oversized radiators and sound-attenuated enclosures. Then we dive into the details of Platinum Protection itself: zero deductibles, 100 % parts-and-labour coverage, factory-trained technicians who come to you, and complete transferability if you ever sell the set. For most buyers, that package would cost about a few hundred dollars, but Aurora is absorbing the fee during this launch window.

    Aurora will automatically register your warranty for an Aurora Diesel Generator powered by Perkins engines. You just need to keep to the normal maintenance schedule. The rest of the generator (alternator, controls, tank, enclosure) continues to be backed by Aurora’s five-year comprehensive warranty.

    Whether you’re designing an off-grid solar system, safeguarding a business, or just tired of unreliable portable generators, this conversation explains why now is the smartest—and least expensive—time to step up to an Aurora Perkins diesel generator set.

    What Is a PTO Generator and Who Uses Them?

    A Power Take-Off (PTO) generator is a mobile electrical power unit that draws its mechanical energy directly from the PTO shaft of an agricultural tractor, truck, or other heavy-duty vehicle. Instead of relying on a self-contained engine, a PTO generator harnesses the engine power of the host vehicle—making it an efficient, space-saving solution for on-site electricity needs.

    How PTO Generators Work
    • Connection: The generator’s input shaft is linked to the vehicle’s PTO output via a splined coupling.
    • Drive: As the vehicle’s engine runs and engages the PTO (typically at 540 or 1,000 RPM), it spins the generator’s rotor.
    • Generation: The rotor’s motion within the stator windings produces alternating current (AC), which is then conditioned by on-board regulation equipment to provide stable, usable power.
    Key Features & Benefits
    • Compact Design: Without an integrated engine, PTO generators are smaller and lighter than standalone units.
    • Cost Efficiency: Shared use of the host vehicle’s fuel and maintenance schedule reduces total cost of ownership.
    • Flexibility: Operators can switch the generator between multiple tractors or trucks, adapting to seasonal or evolving workload demands.
    • Rapid Deployment: Hook-up to the vehicle’s PTO is straightforward, allowing power on-demand for short-term tasks.
    Who Uses PTO Generators?
    • Farmers & Agricultural ContractorsRunning irrigation pumps, grain augers, milking parlors, or fencing equipment in fields without fixed power.
    • Construction & Site ContractorsPowering lighting towers, compressors, and small machinery on remote job sites without hauling separate generators.
    • Utility & Maintenance CrewsProviding spot power for tools and lighting during roadside or rail repairs using truck-mounted PTO units.
    • Event & Rental ServicesSupplying temporary power for outdoor concerts, fairs, and emergency shelters via rented tractors or trucks.
    Is a PTO Generator Right for You?

    If you already operate tractors or heavy vehicles and need intermittent or remote power—especially in agricultural, construction, or utility contexts—a PTO-driven generator may be the most economical and adaptable choice. By leveraging existing equipment, you gain dependable electricity with minimal additional investment and upkeep.
