Injector FAQ
FAQ: What are the reasons for black smoke?
ERIKC Answer: intake and exhaust valve and valve gap fault
Into the exhaust valve carbon deposition, intake and exhaust valve opening and closing time is wrong, and the valve clearance is wrong, or the exhaust valve can not be completely closed, etc. will lead to lower cylinder pressure.
FAQ: What are the reasons for black smoke?
ERIKC Answer: pistons, piston rings, cylinder sleeves and other faults
Cylinder liner wear, piston wear, piston ring heavy rings, etc. (Gas ring oil ring gap coincidence leads to leakage in the cylinder, cylinder pressure decreases.
FAQ: What are the reasons for black smoke?
ERIKC Answer: cylinder head gasket, cylinder head failure
Damage to the cylinder head gasket or deformation of the sealing surface of the cylinder head can cause the cylinder to fail to seal and the cylinder pressure decreases. Whether there is abnormality in cylinder sealing performance can be judged simply by a diagnostic instrument. Compression testing is a software-based engine testing function that is primarily used to test engine cylinder leak tightness. When the compression test is performed, the engine is prevented from starting by prohibiting injection. By measuring the crankshaft speed of each cylinder during compression and power stroke, the relative airtightness of each cylinder can be judged and evaluated by a diagnostic instrument.
