Diesel engine runaway 🥴 🔴Combustion Process - Diesel engines operate on the principle of compression ignition, where air is compressed to high pressures and temperatures, and fuel is then injected into the compressed air to ignite spontaneously. This process is controlled by the engine's fuel injection system under normal circumstances. 🔴Uncontrolled Fuel Source - During a runaway, the engine consumes an uncontrolled external fuel source, such as oil or volatile gases, which bypasses the fuel

⚙️ Causes of Diesel Runaway Here are the most common causes: 1. Turbocharger oil seal failure • The turbo’s oil seals leak, letting engine oil enter the intake. • The engine starts burning this oil like fuel. • Common in older or high-mileage turbo diesels. 2. Excessive crankcase pressure (blow-by) • Worn piston rings or valve seals allow oil mist and vapors into the intake through the breather system. 3. Overfilled engine oil • Too much oil causes it to foam and enter the intake via the breathe
