What is the L-type Electronic Fuel Injection System Like?

[LeRuth]

L-type electronic fuel injection system uses an air flow meter to directly measure the engine's air intake. The ECU does not need to estimate but can calculate the corresponding fuel injection amount based on the air flow meter signal, thus achieving more precise control of the air-fuel mixture concentration. Here is an introduction to the L-type electronic fuel injection system: 1. Working Principle: The flow-sensing gasoline injection system uses an air flow meter to directly measure the engine's air intake. The computer does not need to estimate but can calculate the corresponding fuel injection amount based on the air flow meter signal. 2. Differences between the L-type and D-type systems: The L-type system uses an air flow meter to directly measure the engine's air intake, resulting in higher control precision compared to the D-type system. The control method of the L-type system is also known as the mass flow control method, and most of its structure is similar to that of the D-type system.
