Understanding low speed pre-ignition and its causes

What is low speed pre-ignition (LSPI) and how to prevent it from damaging your engine. Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI) or super-knock, is a phenomenon that occurs in modern turbocharged gasoline direct injection engines. LSPI can result in catastrophic engine damage, often unexpectedly. Why does low speed pre-ignition happen? Engines are designed to ignite fuel in a controlled combustion process. This involves the burning of the air-fuel mixture in the combustion chamber, where the flame starts at the spark plug and spreads evenly. This controlled expansion … Read More
