One day, a tractor driver operated a tractor equipped with 1110-typed diesel engine and discovered the motor powerless, which even gave out some black smoke. The tractor operator even altered the cylinder sleeve, plunger, piston, and lubricating nipple. But all these alterations make no distinction for the perfect performance from the engine operation. Soon after checking the engine, it had been found the degree of pollutant inside the air filter is an excessive amount of. Due to the fact the air filter continues to be polluted, the air intake is blocked, the air flowed into the cylinder is inadequate, consequently triggering the incomplete combustion from the oil combination. In this impression, the motor will give out some black smoke. Once the throttle is tremendously accelerated, the black oil is going to be a lot gathered. Soon after the right clearance from the rod mill, all difficulties will be solved.
According to some fundamental maintenance expertise, the likelihood of the air filter will be greater. The primary reasons are as follows:
1. When the air filter has not been cleaned to get a lengthy time, the air supply within the motor won't be adequate. In this way, the performance from the air filter will likely be lowered and the oil intake might be increased or the engine will even give out significantly black smoke.
2. The air filter may possibly not be obviously cleaned as well as the reasons may perhaps be as follows: the air filter lacks specific sealing gasket or the filter element will get broken, or the AN hose ends get damaged; the JIC fittings don't have any hoop; intake-tube fittings have no gasket – The unfiltered air will probably be flowed into the cylinder, which will cause even higher abrasion for the compression components, such as cylinder sleeve, plunger or valve.
3. Sometimes, in the event the tractor extorts the rod mill of air filter also tightly, some air holes will probably be squeezed to block the flow of air. If 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 into the cylinder. The imbalanced quantity of air and fuel oil within the cylinder will cause some black smoke.
Here are some ways to check out the issues with all the air filter:
1. Cut off the intake of air: Once the diesel motor is under typical 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 the air-flow channel has some problems.
2. Let the air flow to the cylinder freely: When the motor still gives out heavy smoke thought it can be not with excessively loading, we can disassemble the air filter to check whether the smoke will disappear. When the situation is so, it proves the air filter is tremendously obstructed and needs instant treatment. In the event the motor still releases heavy smoke, it means other underlying factors. You need to figure out the exact reasons: the oil injector is not properly pulverized or the oil supply is not correct; pressure in cylinder is fairly low; valve spring is not conventional.
