What are the symptoms of poor diesel injector atomization?
1 Answers
The most obvious symptom of poor injector atomization is vehicle shaking when starting in first gear, which disappears when shifting to higher gears. Other symptoms include lack of engine power, illuminated engine warning light, increased fuel consumption, engine vibration and reduced power, poor acceleration, and failed emissions tests. The main factors affecting injector atomization are poor injector sealing or reduced injection pressure. More related information is as follows: Injector atomization: Poor injector atomization is usually caused by injector clogging, which prevents the injector from achieving the designed fuel injection quantity or atomization effect. Injector clogging occurs due to carbon deposits from the engine settling on the injector or impurities in the fuel blocking the injector. Fuel system deposits: Fuel system deposits can clog the injector's needle valve and valve holes.
