Standard Maintenance of Rod Mill Will Affect Diesel Motor Performance

One day, a tractor driver operated a tractor outfitted with 1110-typed diesel engine and found the engine powerless, which even gave out some black smoke. The tractor owner even changed the cylinder sleeve, plunger, piston, and lubricating nipple. But all these adjustments make no difference to the ideal performance of the motor operation. Right after checking the motor, it absolutely was discovered the amount of pollutant within the air filter is too much. Due to the fact the air filter continues to be polluted, the air intake is blocked, the air flowed in to the cylinder is inadequate, hence triggering the incomplete combustion from the oil combination. Within this sense, the engine will give out some black smoke. When the throttle is significantly accelerated, the black oil is going to be considerably gathered. Soon after the right clearance in the rod mill, all challenges is going to be solved.


According to some basic maintenance encounter, the probability from the air filter will probably be greater. The primary reasons are as follows:


1. In the event the air filter has not been cleaned for a extended time, the air supply within the engine will not be sufficient. In this way, the efficiency from the air filter will likely be reduced and also the oil intake is going to be elevated or the motor will even give out much black smoke.


2. The air filter could not be obviously cleaned along with the reasons may be as follows: the air filter lacks particular sealing gasket or the filter component gets broken, or even the AN hose ends get broken; the JIC fittings haven't any hoop; intake-tube fittings haven't any gasket – The unfiltered air are going to be flowed in to the cylinder, which will cause even greater abrasion for the compression components, such as cylinder sleeve, plunger or valve.


3. Sometimes, if the tractor extorts the rod mill of air filter also tightly, some air holes is going to 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 so as to reduce the intake of air to the cylinder. The imbalanced sum of air and fuel oil within the cylinder will cause some black smoke.


Here are some ways to check out the troubles with all the air filter:


1. Cut off the intake of air: When the diesel motor is under normal operation, you can muffle the air inflow part of air filter, the rotating speed of diesel engine will likely be slow or even become extinguished – this proves the motor 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 issues.


2. Let the air flow into the cylinder freely: When the engine still gives out heavy smoke thought it truly is not with exceedingly loading, we can disassemble the air filter to check whether the smoke will disappear. In the event the situation is so, it proves that the air filter is significantly 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 even the oil supply is not right; pressure in cylinder is particularly low; valve spring is not standard.
