Advantages and Disadvantages

Advantages of Four-Stroke Engine

• Reliability: These types of diesel engines are more reliable and efficient.
• Durability: These engines have high durability than 2-stroke engines.
• Environmental friendly: These engines are environmental-friendly because a 4-stroke engine releases less dangerous fumes than a 2-stroke engine.
• These engine sare best for heavy loads and heavy vehicles.
• Fuel efficiency: These engines have high fuel efficiency than 2-stroke engines.
• Noise: These have a quiet operation than two-stroke engines
• More torque: At low speed, four-stroke engines produce more torque than 2-stroke engines.
• More fuel efficiency: This type of IC engine has higher fuel efficiency than a two-stroke engine.
• No extra oil requirement: This engine does not require any additional lubrication or oil to add the fuel. Only the turning components require lubrication intermediately.
• These diesel engines produce the smallest

Disadvantages of Four-Stroke Engine

• Power: This engine has lower power than the two-stroke engine.
• Expensive: A four-stroke engine has many parts. Therefore, it has high cost than a two-stroke engine.
• Weight: These engines have high weight than 2-strokes engines
• Required area: They required a large area for installation.
• Piston strokes: It requires more piston strokes to complete a power cycle.
• Design: These engines have a complex design.
