Air intake & Exhaust systemsAir intakesystem:-Supplies necessary air to the engine for fuel combustion. It consists of pipes for the supply of fresh air to the engine manifold.-Filters are provided to remove dust particles from air which may act as abrasive in the engine cylinder.Exhaustsystem:-Leads the engine exhaust gas outside the building and discharges it into atmosphere.-A silencer is incorporated to reduce the noise level.
Cooling systemPart of heat released by fuel burning in the engine cylinder passes through the cylinder walls, piston, rings, … etc.and may cause damage to the system.Totemperatureofkeep enginewithinsafeoperatingthe parts limits,cooling is provided.The cooling system consists of a water source, pump and cooling towers. The pump circulates water through cylinder and head jacket. The water takes away heat form engine and itself becomes hot. The hot water is cooled by cooling towers and is re- circulated for cooling.
Lubricating system-Comprises of lubricating oil tank, pump, filter and oil cooler.-Minimizes wear of rubbing surfaces of the engine.-Lubricating oil is drawn from the lubricating oil tank by the pump and is passed through filters to remove impurities.
