True or False: Quiescent Chambers can reduce emissions by increasing injection pressures and the number of spray holes at the injector tip.

Quiescent chambers are designed to improve the combustion process in an engine, particularly by enhancing the air-fuel mixing under certain conditions. By increasing the injection pressure and adding more spray holes at the injector tip, quiescent chambers can create finer fuel droplets and improve atomization. This results in a more efficient combustion process, leading to reduced emissions.

In high-pressure injection systems, the fuel is atomized more effectively, allowing for better mixing with the air in the combustion chamber. This optimization helps in achieving a more complete combustion of the fuel, which is crucial for reducing the formation of unburned hydrocarbons and other harmful emissions. The addition of multiple spray holes also enables a more uniform distribution of the fuel, further enhancing the combustion efficiency and minimizing emissions.

Therefore, the statement is true, as quiescent chambers can contribute to lowering emissions through these enhancements in injection pressures and design features at the injector tip.
