Diesel fuel injection systems components are critical to the performance and emissions of diesel engines. The most crucial component of the fuel system is the fuel injectors/nozzles. Injectors and nozzles need to meet the performance, emissions, reliability, and durability requirements of the engine. The CTP injector nozzle hole size and shape are manufactured to strict parameters using the latest EDM process and are fully tested with laser optic electronic devices to make sure they are built to the exact specifications. Each CTP Injector/nozzle is engineered for exact precision and durability for long service life.
