One day, a tractor driver operated a tractor equipped with 1110-typed diesel engine and located the engine powerless, which even gave out some black smoke. The tractor operator even transformed the cylinder sleeve, plunger, piston, and lubricating nipple. But these modifications make no distinction for the fantastic performance in the engine operation. Soon after checking the engine, it absolutely was discovered that the number of pollutant inside the air filter is an excessive amount of. Because the air filter has been polluted, the air intake is blocked, the air flowed to the cylinder is insufficient, subsequently triggering the incomplete combustion of the oil combination. Within this feeling, the motor will give out some black smoke. Once the throttle is greatly accelerated, the black oil will probably be a lot accumulated. Immediately after the suitable clearance from the rod mill, all troubles are going to be solved.
According to some simple upkeep encounter, the probability with the air filter will probably be higher. The leading underlying factors are as follows:
1. When the air filter hasn't been cleaned for a extended time, the air supply within the engine will not be sufficient. In this way, the performance in the air filter will likely be decreased as well as the oil use might be elevated or the motor will even give out much black smoke.
2. The air filter may perhaps not be obviously cleaned along with the underlying factors may possibly be as follows: the air filter lacks certain sealing gasket or even the filter element will get damaged, or even the AN hose ends get damaged; the JIC fittings haven't any hoop; intake-tube fittings have no gasket – The unfiltered air will likely be flowed to the cylinder, which will cause even higher abrasion to the compression components, such as cylinder sleeve, plunger or valve.
3. Sometimes, when the tractor extorts the rod mill of air filter too tightly, some air holes will probably be squeezed to block the flow of air. In the event the tractor continues to be wrapped by some layers of cotton cloth, air will also be blocked so as to reduce the consumption of air into the cylinder. The imbalanced volume of air and fuel oil inside the cylinder will cause some black smoke.
Here are some ways to check out the complications using the air filter:
1. Cut off the intake of air: Once the diesel engine is under ordinary operation, you can muffle the air inflow part of air filter, the rotating speed of diesel motor will probably be slow or even become extinguished – this proves the engine works normally. When the revolving speed of diesel engine has no change or just has slight change, it proves that the air-flow channel has some problems.
2. Let the air flow into the cylinder freely: When the engine still gives out heavy smoke thought it truly is not with excessively loading, we can disassemble the air filter to check whether the smoke will disappear. If the situation is so, it proves that the air filter is tremendously obstructed and needs instant treatment. If the motor still releases heavy smoke, it means other reasons. You need to figure out the exact reasons: the oil injector is not properly pulverized or even the oil supply is not suitable; the pressure in cylinder is quite low; valve spring is not normal.
