TLDI verses Carburetor
TLDI is an abbreviation that stands for Two-stroke Low-pressure Direct Injection.
The air assisted, low-pressure direct injection system has been combined with the in-
ducted ignition system and the Engine Control Unit, which performs control or fuel mix-
ture, injection timing and ignition timing to maximize combustion efficiency in the TLDI
engine. The result is better fuel economy, lower maintenance, ability to burn multi-fuels
and capable of submersion.
The air-assisted Low-pressure direct fuel injection process involves using an air com-
pressor to pressurize the fuel supplied by the fuel pump and inject it directly into the
combustion cylinder in the form of a finely atomized mixture that achieves maximum
combustion efficiency.
Below is a simple diagram of how the TLDI engine operates and the conventional carbu-
retor engine to show the differences.
