Introduction

The TP-STP Injector Less Link, manufactured by Cummins, is a component designed for use in heavy-duty truck engines. Its purpose is to facilitate the operation of the fuel injection system by providing a mechanical linkage that ensures precise control over fuel delivery. Cummins, a well-established name in the diesel engine industry, produces this part to meet the demanding requirements of heavy-duty applications ¹.

Function and Operation

The TP-STP Injector Less Link operates within the fuel injection system by connecting the fuel injector to the engine’s camshaft. This connection allows the camshaft to actuate the fuel injector at the precise moment required for optimal combustion. The link translates the rotational motion of the camshaft into linear motion, which opens the injector nozzle to release fuel into the combustion chamber. Its interaction with other components, such as the camshaft and fuel injector, is crucial for the timing and quantity of fuel delivered to the engine ².
