The difference between steam turbine and reciprocating engine is given bellow: Steam Turbine Reciprocating Engine In steam turbine working fluid is steam. In reciprocating engine working fluid is fossil fuel. Steam turbine efficiency is high and it is more than 60 %. Reciprocating engine efficiency is low and it is 30 to 40 %. Steam turbine vibration is low. But reciprocating engine vibration is high. Steam turbine has proper balancing. Reciprocating engine is unbalance or weak balance. Steam turbine lubrication is negligible. Reciprocating engine lubrication is major. Steam turbine design is simple. Reciprocating engine complex and compact. It is design for high power output. It is design for low power output. Steam turbine generates uniform power. Reciprocating engine do no

Car Engine Failure to start: a.       No fuel in tank or carburetor. b.       Slag fuel tank in vane. c.       If fuel pump supply fuel with line leakage.  d.      Leaky float.  e.       Leaky float. f.        If air does not supply properly.                    

By following reciprocating engine basic features of rotary engine given bellow 1.       There are no reciprocating parts. Thus the problems of inbalance caused by the inertia of reciprocating parts and complicated engine vibration is eliminated. In rotary engines vibrations is very low because it is possible to perfectly balance the engine by using the balancing weights. Also rotary engine does not require a cranking mechanism, it has the advantage of smooth motion, less mechanical loss, simple construction and compactness. 2.       There is no separate intake –exhaust valve mechanism. In a reciprocating engine intake exhaust valve mechanism generates mechanical noise by opening and closing of the valves and the valves themselves obstruction air flow. Due to inertia of valve mechanism, the valves are unable to fully follow the motion of the cam at high revolutions. This results in variation in effective valve timings of the engine. But a rotary engin
