Two stroke engines have power strokes every revolution, while four stroke engines have power strokes every other revolution.
Two stroke engines have a simpler design with fewer moving parts compared to four stroke engines
Two stroke engines require a fuel-oil mixture for lubrication, while four stroke engines have a separate oil reservoir
Two stroke engines produce more pollution due to incomplete combustion, while four s...
Wind Turbine Generators (WTG) generate electricity through the conversion of wind energy into mechanical energy and then into electrical energy.
Wind turns the blades of the turbine
Blades are connected to a rotor
Rotor spins a generator to produce electricity
Electricity is then sent to a transformer for distribution
Example: Vestas V164-9.5 MW wind turbine
Fluid couplings are used to transmit power from one shaft to another without direct physical contact, allowing for smooth start-ups and overload protection.
Fluid couplings help in gradual acceleration of heavy machinery, reducing stress on the equipment
They provide overload protection by slipping when the torque exceeds a certain limit
Fluid couplings dampen torsional vibrations, reducing wear and tear on the machinery
T...
