All About Power

Engine & Engine Working. Engine is a mechanical machine that convert fuel chemical energy in to mechanical energy.Some machine needs mechanical energy to do work.Pumps and compressors can be driven by the mechanical energy supplied  by internal combustion engines.This mechanical energy of internal combustion engine is converted electrical energy with alternator. All internal combustion engines burn fuel inside a cylinder to produce power.Internal combustion engines are classified according to the way of fuel and ignition.According to ignition internal combustion engines have two types. Compression ignition engine. Spark ignition engine. Compression ignition Engine. Compression ignition engines work on diesel cycle.Compression ignition engines are diesel engines or (HFO) heavy furnace oil engines.In compression ignition engines do not need a spark to ignite the charge.Compression ignition engines compress air inside the cylinder to very high pressure.fuel is pumped wi

Gas turbine starting system and self shifting clutch. In gas turbines latest technology of self shifting clutch to engage variable frequency drive AC to moter with turbine. Gas turbine startup system. In gas turbine the starting system provides torque with self shifting clutch to initiate engine rotation to reach ignition speed.when combustion occurs turbine shaft accelerate self sustaining speed approx 60% the starting moter de energised self shifting clutch.

Gas turbine compressor failure maintenance. Gas turbine axial flow compressor failure due to fouling or corrosion and damaged blades.

Valve clearance or valve lash is measured with a feeler gauge setting Gage put between the rocker arm contact and the bridge wear seat. Valve clearance is changed using a screwdriver. A 3/4 inch wrench is needed to loosen and tighten the lock-nut which holds the adjustment screw. To make the adjustment, turn the adjustment screw until you feel an easy pull on the feeler gauge as you move it backward and forward between the rocker arm contact and the bridge wear seat. Tighten the nut on the adjustment screw and check the adjustment to be sure it has not changed. The adjustment of all valves and the injectors can be done by putting the engine crankshaft in two positions. Refer to the Service Manual for these procedures.

Caterpillar Engine Turbocharger. An exhaust driven air compressor. Impeller on the left side of turbocharger. Turbine on the right side. Connecting shaft,free floating bearing,oil lubrication center housing. Causes Of Premature Wear or Failure. Poor oil quality. Dirt ingestion. Hot engine shutdown. Signs up quicker for good engine response. Regulates turbocharger speed and prevents over speeding. The wastegate is opened by the high pressure boost in the compressor side of the turbocharger. Some of the exhaust gas then bypasses the turbine and escapes wastes to the exhaust stack. Caterpillar Engine Turbocharger Failure. If the turbocharger fails during engine operation  damage to the turbocharger compressor wheel or to the engine may occur.Damage to the turbocharger compressor wheel could allow parts from the compresser wheel to enter an engine cylinder.This can cause additional additional damage to the the piston,valves and the cylinder head.
