It is a semi -solid lubricant consisting of high viscosity mineral oil and metallic soap with filler . Metallic soaps are compound of sodium , calcium and aluminium . While filler are lead , zinc , graphite and molybdenum .
Since indicator card is not used to calculate the power card because we will not be recognise the firing TDC because in a same cycle piston is at TDC twice . Hence with the help of pressure gauge it can be find out .
Normally in jerk type fuel pump only end of injections control while in vit we have beginning and end of injections both control . Therefore we are getting the p Max at 85% of MCR . with the use of Vit fuel economy can be increased . In case of super vit we can have control over injection timing with fuel index and breaking point . Breaking point is the point after which pressure deceleration takes place . Vit = variable beginning of injection + variable end of injection =adjustable timing of injection Super vit = variable beginning of injections + variable end of injection + adjustable breaking point
Bearing clearance measurement with bridge gauge with depth gauge and vernier . Port to stbd bridge gauge earlier collar with hole . Sulzer is having bridge gauge . Man B & W having telescopic pipe through lube oil holes . Diagram is important.
1. Talk when they are free ...because office people are busiest people . 2. Slowly introduce take time . Don't complete entire conversation in one statement . 3. Introduce within 30 sec. 4.
