Telangana State Road Transport Corporation Mechanical Foreman Interview Questions, Process, and Tips

A piston is a component in an engine that moves up and down within a cylinder, helping to convert pressure into mechanical energy.

• A piston helps to transfer force from expanding gas in the cylinder to the crankshaft

• It creates a seal within the cylinder to contain the combustion process

• Pistons are typically made of aluminum alloy or cast iron

• They are connected to the crankshaft via a connecting rod

A turbocharger is a device that increases the efficiency and power output of an internal combustion engine by forcing extra air into the combustion chamber.

• Turbochargers use exhaust gases to spin a turbine, which in turn drives a compressor to force more air into the engine.

• This extra air allows more fuel to be burned, resulting in increased power output without the need for a larger engine.

• Turbochargers are commonly u...read more

Some parts of an engine include piston, crankshaft, cylinder head, and camshaft.

• Piston: Moves up and down in the cylinder, creating power.

• Crankshaft: Converts the up and down motion of the piston into rotational motion.

• Cylinder head: Covers the top of the cylinder and contains valves and spark plugs.

• Camshaft: Controls the opening and closing of the engine's valves.

Most engines have four strokes: intake, compression, power, and exhaust.

• Engines typically have four strokes: intake, compression, power, and exhaust

• Each stroke plays a specific role in the combustion process

• Examples of engines with four strokes include gasoline and diesel engines

Cooling is necessary for engines to prevent overheating and maintain optimal operating temperature.

• Cooling helps dissipate heat generated during combustion process

• Prevents engine components from warping or seizing due to excessive heat

• Maintains optimal operating temperature for efficient performance

• Improper cooling can lead to engine damage or failure

• Examples: Radiators, coolant systems, fans

The gear used for PTO is typically a spur gear.

• Spur gears are commonly used for PTO applications due to their simplicity and efficiency.

• They are designed to transmit power between parallel shafts.

• Other types of gears like helical gears or bevel gears can also be used depending on the specific application.
