Injectors are precision components operating at microscopic tolerances, spraying fuel at pressures up to 2500 bar. Over time, nozzle wear, high back-leak, or solenoid failures cause black smoke, hard starting, and high fuel consumption. At the Simsek Pompa Injection Laboratory, we subject your Bosch, Delphi, Denso, and Siemens VDO injectors to "Spray Pattern" and "Response Time" tests on state-of-the-art test benches. We replace faulty internal parts (nozzle, valve, solenoid) with genuine ones and perform the most critical step, IMA/QR Coding, ensuring the injector works in 100% harmony with the engine.
