3. What is TLDI?
Direct Fuel Injection System
1.
TLDI (Two-stroke Low-pressure Direct injection)
TLDI is a kind of two stroke engine system that adopts air-assisted low pressure direct fuel injection.
The adoptions of the air-assisted low pressure direct fuel injection system and digital inductive ignition system and
control of factors by means of ECU (Engine Control Unit) such as fuel injection amount, fuel injection timing and
ignition timing provide fuel combustion at higher efficiency, lower fuel consumption and lower emission, as well as
powerful performance that is one of outstanding features of two stroke engines.

Air-assisted low pressure direct fuel injection
The air-assisted low pressure direct fuel injection is a system that directly injects fuel compressed with a fuel pump
into the combustion chamber with the assistance of the air that is compressed with an air compressor. The injected
fuel is an air-mixture that is very finely atomized, providing fuel combustion at higher efficiency.
