Combustion on diesel motor, happened because fuel which injection into cylinder burnt by it self effect of height air compresi in room burnt.

• Step suckPiston moving from TMA to TMB, spillway enter opening and exhaust valve

closed. Pure water sipped enter into cylinder to be resulted emptiness cylinder room. Because spillway enter has opened.

• Step of compressi Axis crank rotary but spillway tightly closed, piston moving from TMB to TMA.

Pure air which sipped into cylinder step moment suck, compress until pressure and temperature go up reaching 35 atm with temperatur 8000o C .

• Combustion step Axis crank continue to rotate some degree before torak reaching TMA. injector

fuel hypodermic to room burn.

• Dismissal stepOpen exhaust valve and move from TMB to TMA Caused any dampness style

had by style wheel which axis with balanced crank shaft.

Fungtion for arrange pure air supply and expenditure of gas is rest of combustion by opening and closing both spillway.

Spillway mechanism in diesel machine1. camshaft2. tappet3. pushrod4. rocker arm5. Spillway along with its spiral spring.

Way of job :When motor work gear axis crank rotary movement gear cam so that axis cam also followrotating Because surface axis cam which form ecsentris so that lever related him tend

to to make a move fluctuate as according to form surface of cam axis which movement

Way of decompression systemdecompression lever pulled by part of compressor spillway depressing spillway can open. if at the time is step compression pressure of compressi will leak to open.Fungtion :To leak or increase pressure of compressi at start early by depressing / opening spillway, so that twiddling of crank become lighterly

Fungtion :Air supply : To channel pure air into room burn at step suck dismissal channel.

Dismissal channel.Fungtion : Channelling gas ex- rest of combustion into air outside and at the same time function as silencer of rotation effect combustion explosion and also gas pressure throw away.

Fungtion : • To lessen Direct contiguity or friction among two surface of machine

component which moving each other by forming coat of oli flimsy surface both of component.

• Cooler ( hot absorber passed by component it )• Perapat ( preventative leakage of compressi among piston ring and

cylinder)• Cleaner ( dissolving of metal particle dirt result of friction)

Diesel machine fuel is solar (diesel fuel). Good criterion diesel fuel : • Is not volatile at normal temperature• Flammable [at] temperature between 3500C - 5000C• Do not easy to froze up me at cool temperature• Owning viscosity which enough so that easy to sprayed by injector• Obstetrical its low sulphur• have Energy commenting to and nozzle• Have Number of cetane ( ability prevent knocking) which enough

fungtion : To lessen timeworn of peripatetic machine components ( friction) with forming flimsy coat surface of machine component.Especial components system Iubrication of generator diesel motor :a. oil panb. oil screenc. oil pumpd. oil filtere. oil signalf. Channels dealer of lubricating oil to user component.

Way of Iubrication system job

when generator diesel motor work, pump of oli partake to rotate with cam axis which attributing to pump axle end. Work him pump oli cause Iubricant residing in pan of oli or of karter inhaled to the through harsh filter. After passing oil pump filtered by softer filter. And pouring into indicator of oil Iubricant. emiting components needing Iubrication.
