Peugeot 405 Piston

Peugeot 405 Piston

The piston in a Peugeot 405 is one of the main components of the engine, playing a crucial role in converting the energy produced from fuel combustion into mechanical motion. Pistons are placed inside the engine's cylinders and, through their reciprocating motion, transfer force to the crankshaft, which ultimately causes the wheels to turn and the vehicle to move.

Functions of the Piston

The piston in the Peugeot 405 is essential in the four main stages of engine operation: intake, compression, combustion, and exhaust:

1. Intake Phase: The piston moves downward, drawing the air-fuel mixture into the cylinder.
2. Compression Phase: The piston moves upward, compressing the air-fuel mixture.
3. Combustion Phase: A spark from the spark plug ignites the compressed air-fuel mixture, forcing the piston downward.
4. Exhaust Phase: The piston moves upward again, expelling the exhaust gases out of the cylinder.

Structure and Material of the Piston

Peugeot 405 pistons are made from lightweight and heat-resistant alloys such as aluminum. These alloys are ideal for pistons due to their light weight, good heat conductivity, and high resistance to pressure and heat. The pistons also have compression and oil rings that provide cylinder sealing and reduce friction.

Signs of Piston Wear

Over time and with continuous use, pistons may wear out or become damaged. Some signs of piston wear include:

• Reduced engine power
• Increased oil consumption
• Reduced compression pressure
• Blue or white smoke from the exhaust

Maintenance and Repair

To extend the life of pistons and prevent sudden failures, it is recommended to change the engine oil regularly, use high-quality fuel, and follow scheduled maintenance. If signs of wear are detected, replacing the pistons with original and high-quality parts can improve engine performance.

Healthy and high-quality pistons help increase engine efficiency, reduce fuel consumption, and prevent more significant engine failures.
