Diesel engine fault by the laws of sound judgment

The early stage of development of the diesel generators, noise, black smoke, can only be used in agricultural machinery needs large traction on, with the development of diesel technology, many imported cars have diesel models selectable. Well-designed diesel engine sound more pleasing to the ear, on the structural characteristics of gasoline, so easily judged by some characteristics of the voice of the fault lies in where.
(1) The diesel engine is a regular continuous fat ring, generally is a fault with the rotary member. In case of continuous knocking sound, often occurs in the timing gears, flywheels and other parts.
(2) diesel engine issue regular intermittent sound, generally the engine attachment failure, such as generators, starters, air compressors, pumps, etc., the installation is not strong or internal touch scraping fat ring.
(3) Diesel engine revolution of abnormal sound appear generally related to the crankshaft parts, such as pistons, piston pins, piston rings and connecting rod bearing failure.
(4) diesel engine per revolution twice abnormal sound appears once, generally faulty camshaft-related parts, such as valve, push rod, valve springs and timing gear damage.
