Diesel engines burn fuel through compression ignition. Air is drawn into the cylinder and compressed to a high pressure, which significantly increases the temperature. When diesel fuel is injected into the cylinder, the high temperature of the compressed air causes the fuel to ignite without the need for a spark plug. This combustion process powers the engine.
FAQs & Answers
- What is compression ignition? Compression ignition is a method of igniting fuel in diesel engines by compressing air to a high temperature, eliminating the need for spark plugs.
- What is the difference between diesel and gasoline engines? Diesel engines use compression ignition while gasoline engines utilize spark ignition, leading to different efficiency and power characteristics.
- What roles do air and fuel play in a diesel engine? In diesel engines, air is compressed to a high temperature, and when diesel fuel is injected, it ignites, resulting in combustion that powers the engine.
