1.05L REVOTORQ ENGINE 76 D. LUBRICATION SYSTEM Lubrication System Schematic Layout :  Description : The lubrication system layout is as shown in the schematic above. The oil pump is mounted in- side the crankcase. Oil is drawn up from the sump through oil pump strainer and passes through the pump to the oil cooler and then to the filter. The filtered oil flows through the internal drilled holes into the crankshaft oil gallery from here it is supplied to connecting rod bearings and also to the main bearings by means of intersecting passag- es drilled in the crankshaft. It is then injected through the cooling nozzles to the underside of the piston / piston gallery for cooling. There is a sepa- rate line that goes to lubricate the turbocharger and the air compressor. There is another path which takes the oil up from the crankshaft oil gallery to camshafts oil gal- lery in cylinder head and lubricates the camshaft. The camshaft oil gallery also provides the oil need- ed by the rocker arm. The relieved oil drains back to oil sump. The Lubrication System consists of the fol- lowing components. 1. Oil Pump 2. Oil Filter. 3. Oil Strainer. 4. Oil Cooler. 5. Hydraulic Lash Adjuster (HLA) 6. Piston Cooling Nozzles. 7. Oil Pressure Switch
