PERFORMANCE ANALYSIS OF TWO CYLINDER DIESEL ENGINE VIBRATIONS USING DIFFERENT ENGINE MOUNTINGS

MECHANICAL ENGINEERING

The effective approach of reducing the vibration transmitted from the engine to the supporting structures is by the employment of Engine mounts. A 2 cylinder 4-stroke cool direct injection ICE with a displacement volume of 998cc, compression quantitative relation eighteen.5:1, developing seventeen power unit at 2000 rev was used for this analysis work. The engine is fitted with typical fuel injection system system, that includes a five hole nozzle of zero.262mm separated at 1460, inclined at associate degree angle of 600 to the cylinder axis. The widget gap pressure counseled by the manufacturer was 250 bar. 2 forms of mountings that area unit utilized in this project area unit rubber mounting and hydraulic mounting. At totally different masses ( third, 25%, 50%, seventy fifth and 100%) of the utmost load (90NM@3600RPM) and rpm(1200) vibrations area unit measured within the Dewe soft package victimisation varied sensors. currently the rubber mounting is replaced with the Hydraulic Mounting and therefore the readings area unit noted within the package. The vibration sensors used for measurement the vibrations in FFT instrument and measuring instrument. These sensors area unit connected to the Dewe package victimisation analog cables and adapter The readings obtained area unit enforced and compared in an exceedingly Graph victimisation stand out package. so the appropriate mounting that may be used for reducing the vibrations in associate degree engine is analysed.
