Its length of 805 mm and outer diameter of 33 mm are designed to fit seamlessly into the fuel rail assembly. This accumulator helps absorb pressure spikes and fluctuations, which are common during high-demand operating conditions, thereby protecting sensitive components from damage. By maintaining steady fuel pressure, it contributes to efficient combustion, reduced emissions, and improved fuel economy. The accumulator’s construction is tailored to withstand the high pressures and temperatures typical of modern diesel engines. Properly functioning, it supports smooth engine operation and responsive throttle performance.
