How do you fix wet stacking?
The general cure for wet stacking is a few hours of operation at a load of about 75% to 100% of the generator’s nameplate rating, raising the exhaust temperature high enough to vaporize the unburned fuel in the exhaust system and blow out the soot.
What is wet stacking and how can it be prevented?
How to Prevent Wet Stacking. The effects of wet stacking can be rectified by running the generator set at or above 75% of the generator’s nameplate rating. This allows for increased exhaust temperatures which vaporize the unburned fuel in the exhaust system.
What causes wet stacking in diesel generators?
Wet stacking refers to a condition where a diesel engine has a thick, dark liquid substance dripping from its exhausts. The condition occurs when a diesel engine’s un-used/unburned fuel, carbon particles, and accumulated moisture gather around the exhaust system components.
What is wet stacking on a tractor?
Wet stacking is a condition in diesel engines in which unburned fuel passes on into the exhaust system. Cold weather running or other causes that prevent the engine from reaching proper operating temperature can cause a buildup of fuel due to incomplete burn that can result in ‘wet stacking’.
What causes high EGT in a diesel?
The richer the air/fuel ratio in a diesel, the higher the EGT will be. Two things can create a rich mixture under heavy loads or at full throttle: the first is too much fuel, and the second is not enough air.
What does load mean on a diesel?
In diesel engines, the engine speed is adjusted by the fuel taken into the engine’s cylinders. The power generated by the engine is also adjusted by increasing or decreasing the fuel sent into the cylinders. Engine load is the expression of reducing or increasing the desired power to be withdrawn from the engine.
How is load control achieved in a diesel engine?
The load control in the diesel engine is achieved by adjusting the fuel quantity instead of throttling the air.
How is diesel engine load calculated?
The best ( but not fully correct ) way to determine your engine load is to compare your actual fuel Flow at a given rpm vs the manufacturer published fuel flow at full throttle at the same given rpm. Divide your numbers vs the full throttle numbers and you will have a roughly load in % at a specific condition.
How engine speed is controlled?
The engine RPM is monitored by the crankshaft position sensor which plays a primary role in the engine timing functions for fuel injection, spark events, and valve timing. Idle speed is controlled by a programmable throttle stop or an idle air bypass control stepper motor.
How fast is a four stroke engine?
The medium speed four-stroke engine (250 – 1200 rev/min) is used for the auxiliaries such as alternators and also for main propulsion with a gearbox. A four-stroke diesel engine resembles a gasoline engine as it works on the four-stroke cycle, that is: admission, compression, power and exhaust.
How fast will a 250 go?
A 250cc dirt bike comes at a maximum speed of 55-70 mph (90-113 km/h) depending on a type of engine.
How fast does a 125 2 stroke go?
The max speed for a 125cc 4-stroke dirt bike is it going to be around 50 miles per hour while the max speed for a 125cc 2-stroke dirt bike is going to be around 70 miles per hour.
