Diesel Engine Preface
How a diesel engine works ?
• Turn key is used for ignition.
• Fuel pumps deliver the fuel from the fuel tank to the engine.
• The fuel injection pump pressurizes fuel into a delivery tube.
• The fuel, air, and “fire” meet in the cylinders.
• Combustion spreads from the smaller amount of fuel that’s
placed under pressure in the precombustion chamber to the
fuel and air in the combustion chamber itself.
