- PT injector converts the low-pressure fuel supplied by the PT fuel pump into a high-pressure (about 70-138 MPa) fuel injection into the combustion chamber.
- The series of injectors includes three types, basic type, top positioning type and STC type. The basic type is a PTD type cylindrical injector (see figure top), and the plunger stroke of which needs to be adjusted on the engine. The plunger stroke of top positioning type (see figure middle) and STC type injectors (see figure buttom) need to be adjusted on injector.
- STC type of fuel injector adopts “injection advance timing method” (fuel to be injected in the compression cycle as earlier as possible) under starting and light load conditions, which improves the idle speed characteristics in cold weather, reduces smoke emitted by engine in cold weather, and improves the fuel economy under light load conditions.
- It adopts “normal timing method” (fuel to be injected normally in the compression cycle) under the medium and heavy load conditions, which controls the maximum burst pressure of the cylinder and reduces the emission of NOx (nitrogen oxides).
