Low-speed pre-ignition (LSPI) is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. Learn about its causes, effects, impact on engine design, and potential solutions from this Wikipedia article.
Learn what LSPI is, how it can damage your turbocharged engine and how Mobil 1™ motor oils can help prevent it. Find out which Mobil 1™ products meet the API SP specification for LSPI protection.
Technically speaking, LSPI is an abnormal combustion even caused by the higher in-cylinder pressures common in modern engines — those that are turbocharged and/or GDI — while operating under low-speed, high-torque conditions. If you're currently driving a vehicle with one of these engines, pay close attention to what we're about to tell ...
LSPI is the inventor and market leader of drag reducer products that improve pipeline flow and reduce energy costs. LSPI offers injection equipment, field service, technical support, quality production and reliable supply chain for its customers worldwide.
LSPI stands for low-speed pre-ignition, an abnormal combustion event that can cause catastrophic engine failure. Learn how LSPI happens, how to prevent it with oil formulation and other methods, and how to recognize the symptoms.
LSPI is an unplanned combustion event that can damage gasoline direct injection engines. Learn what causes LSPI, how to avoid it and how oil companies help prevent it with API SN Plus specification.
Low Speed Pre-Ignition (LSPI) is a phenomenon that can occur in modern, high-compression engines with direct fuel injection and turbocharger. It can cause severe mechanical issues like blown head gasket, piston rings or connecting rod bearing. Learn how to avoid LSPI with proper motor oils and injector cleaner.
LSPI stands for Low Speed Pre-Ignition, a phenomenon that can damage modern engines with direct injection. Learn how to avoid LSPI with the right motor oil and driving habits from LIQUI MOLY, a leading manufacturer of high-quality lubricants.
LSPI is also called Stochastic Pre-Ignition, SPI...the word stochastic is key, telling us that it is a random process whose probability can be affected by conditions like engine load, RPM, oil composition, etc. Classic knock is also affected by the conditions of the engine, but the correlation to spark timing is strong and classic knock control ...
LSPI was simply a more damaging pre-ignition event that was peculiar to turbocharged direct-injected small displacement engines. While the cause of LSPI is not yet fully understood, testing revealed that improvements to the blending of engine lubricants could help mitigate the problem. These updated oils soon began to appear on the shelves of ...
