Injector FAQ
FAQ: Endoleak, long injection time, start-up difficulties?
ERIKC Answer:When the needle valve makes frequent reciprocating movements inside the needle valve hole, if the diameter of the impurity particles in the diesel oil is too large, the guide surface of the needle valve hole gradually wears, resulting in increased internal leakage of the injector, pressure drop, and extended injection time. , causing the diesel engine to start difficult and increase vibration during work.
FAQ: Is there a leak in the combined hole of the injector and the cylinder head?
ERIKC Answer:If the fuel injector has carbon deposits in the mounting holes on the cylinder head, the copper gaskets are not perfect, and the copper gaskets are not replaced by the copper material, or the thickness of the gasket does not ensure that the injector extends beyond the plane of the cylinder head. Causes poor heat dissipation or does not achieve a sealing effect, resulting in leakage of gas at the joint hole of the injector and the cylinder head.
FAQ. Black smoke?
ERIKC Answer:Due to continuous jet flushing of the high-pressure diesel oil, the nozzle orifice will increase due to gradual wear, resulting in a drop in injection pressure, a shortened injection distance, and an inhomogeneous mixing of the combustible mixture, resulting in a black smoke phenomenon in the diesel engine. Charcoal will also increase.
