One day, a tractor driver operated a tractor outfitted with 1110-typed diesel motor and discovered the motor powerless, which even gave out some black smoke. The tractor proprietor even changed the cylinder sleeve, plunger, aide, and lubricating nipple. But every one of them changes make no distinction towards the ideal efficiency with the engine operation. Soon after checking the engine, it had been discovered the number of pollutant in the air filter is too much. Considering that the air filter continues to be polluted, the air intake is blocked, the air flowed into the cylinder is inadequate, as a consequence leading to the incomplete combustion in the oil mixture. Within this feeling, the motor will give out some black smoke. When the throttle is greatly accelerated, the black oil will probably be significantly accumulated. Right after the right clearance in the rod mill, all difficulties might be solved.
According to some fundamental upkeep knowledge, the probability of the air filter might be greater. The leading underlying factors are as follows:
1. In the event the air filter hasn't been cleaned for any lengthy time, the air supply in the engine won't be adequate. Within this way, the performance in the air filter is going to be decreased along with the oil use will be elevated or even the motor will even give out much black smoke.
2. The air filter may possibly not be clearly cleaned as well as the underlying factors may be as follows: the air filter lacks certain sealing gasket or even the filter component gets damaged, or the AN hose ends get damaged; the JIC fittings haven't any hoop; intake-tube fittings haven't any gasket – The unfiltered air is going to be flowed into the cylinder, which will cause even better 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. If the tractor has been wrapped by some layers of cotton cloth, air will also be blocked so as to reduce the consumption of air to the cylinder. The imbalanced degree of air and fuel oil within 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: When the diesel engine is under ordinary operation, you can muffle the air inflow part of air filter, the rotating speed of diesel engine is going to be slow or even become extinguished – this proves that the engine works normally. In the event the revolving speed of diesel motor has no change or just has slight change, it proves that the air-flow channel has some challenges.
2. Let the air flow to the cylinder freely: If the engine still gives out heavy smoke thought it can be not with overly 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. When the motor still releases heavy smoke, it means other reasons. You need to figure out the exact underlying factors: the oil injector is not properly pulverized or even the oil provide is not right; pressure in cylinder is exceptionally low; valve spring is not regular.
