Pressure Accumulator
Detroit Diesel

This pressure accumulator is essential for dampening fuel pressure fluctuations within the high-pressure injection system. Its 33 mm outer diameter and nearly 900 mm length allow it to absorb pressure surges, stabilizing fuel delivery and protecting system components from stress. Capable of withstanding a working pressure of 900 bar, the accumulator ensures consistent fuel pressure, which is vital for precise injection timing and combustion efficiency. Constructed from durable materials, it maintains performance over a wide temperature range from -40°C to +120°C. Its role in smoothing out pressure peaks helps reduce noise, vibration, and mechanical wear, extending the lifespan of the entire fuel system. Properly functioning pressure accumulators are critical in high-performance diesel engines, supporting optimal power output and emissions compliance. Source One Parts Center recommends this component for its robustness and contribution to fuel system stability.
