An injector nozzle is used to inject the prescribed volume of fuel inside the combustion chamber after receiving a signal from electronic sensors in the automobile. The fuel enters the nozzle at a high pressure, which is then passed through extra thrust into the engine cylinder. The fuel is injected in the nozzle in the form of spray. As injector nozzles help in reducing emission from the engine and maintaining the engine performance, nozzle shape, injector sac, injector seat, and size of the nozzle hole are precisely monitored while making them.
Automakers around the world are increasingly installing injector nozzles in their offerings to comply with the toughening vehicle emission standards, owing to which, the injector nozzle market will prosper in the upcoming years. For instance, the Euro 6 standards caused a sharp reduction in nitrogen oxides (NOx) emission from light-duty vehicles from 2.0 g/kWh to 0.4 g/kWh in steady-state testing and from 2.0 g/kWh to 0.46 g/kWh in transient testing.
According to P&S Intelligence, the North American injector nozzle market advanced at the highest rate in the preceding years due to the huge requirement for domestic vehicles in the region. Moreover, the toughening emission laws of the U.S. will also encourage the integration of injector nozzles in automobiles in the region. For instance, the U.S. Environmental Protection Agency (EPA) has laid down the Heavy-Duty Highway Engine: Clean Fuel Fleet Exhaust Emission Standards and Phase 1 Greenhouse Gas Emission Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles to reduce emission from medium- and heavy-duty vehicles.
