One day, a tractor driver operated a tractor equipped with 1110-typed diesel engine and located the motor powerless, which even gave out some black smoke. The tractor operator even modified the cylinder sleeve, plunger, piston, and lubricating nipple. But every one of those modifications make no distinction towards the excellent efficiency of the motor operation. Just after checking the engine, it absolutely was identified that the amount of pollutant within the air filter is too much. Since the air filter continues to be polluted, the air intake is blocked, the air flowed into the cylinder is inadequate, subsequently creating the incomplete combustion from the oil mixture. In this sense, the motor will give out some black smoke. Once the throttle is greatly accelerated, the black oil is going to be much gathered. Immediately after the suitable clearance in the rod mill, all complications will probably be solved.
According to some basic maintenance experience, the probability with the air filter will likely be greater. The leading underlying factors are as follows:
1. In the event the air filter hasn't been cleaned to get a lengthy time, the air supply in the engine will not be adequate. In this way, the performance of the air filter are going to be decreased along with the oil intake is going to be increased or even the motor will even give out much black smoke.
2. The air filter may not be clearly cleaned plus the reasons may perhaps be as follows: the air filter lacks certain sealing gasket or the filter component gets damaged, or even the AN hose ends get damaged; the JIC fittings haven't any hoop; intake-tube fittings haven't any gasket – The unfiltered air will likely be flowed into the cylinder, which will cause even higher abrasion towards the compression components, such as cylinder sleeve, plunger or valve.
3. Sometimes, when the tractor extorts the rod mill of air filter also tightly, some air holes are going to 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 in order to reduce the consumption of air to the cylinder. The imbalanced number of air and fuel oil inside the cylinder will cause some black smoke.
Here are some ways to check out the difficulties with the air filter:
1. Cut off the intake of air: Once the diesel motor is under usual operation, you can muffle the air inflow part of air filter, the rotating speed of diesel motor are going to be slow or even become extinguished – this proves that the motor works normally. In the event the revolving speed of diesel motor has no change or just has slight change, it proves the air-flow channel has some issues.
2. Let the air flow into the cylinder freely: If the motor still gives out heavy smoke thought it is not with overly loading, we can disassemble the air filter to check whether the smoke will disappear. In the event the situation is so, it proves the air filter is significantly obstructed and needs instant treatment. When the engine still releases heavy smoke, it means other underlying factors. You need to figure out the exact underlying factors: the oil injector is not properly pulverized or the oil provide is not appropriate; pressure in cylinder is exceptionally low; valve spring is not typical.
