👉 The pilot fluid, also known as the pilot injection or pilot charge, is a critical component in internal combustion engines, particularly in high-performance and turbocharged applications. It serves as a supplementary fuel source that is injected into the intake manifold or directly into the combustion chamber during engine startup or under specific operating conditions, such as high altitude or cold temperatures. This additional fuel boost enhances engine power and torque by increasing the combustion efficiency and ensuring a smooth, reliable ignition process. The pilot fluid is typically a specially formulated mixture of fuel and oxygen or other additives, designed to provide the necessary boost without compromising engine performance once the main fuel supply is established.
