JZHY Launches JZ-326B Pro Diesel Common Rail Piezo Injector Test Bench for 4-6 Injector Simultaneous Testing

Wuxi City, Jiangsu, China — JZHY, a professional manufacturer of diesel fuel injection testing equipment, is proud to announce the launch of its latest innovation: the JZ-326B Pro Diesel Fuel High Pressure Common Rail Piezo Injector Test Bench. Designed for modern diesel repair and service workshops, the JZ-326B Pro allows technicians to test 4 to 6 piezo injectors simultaneously, significantly boosting workshop throughput while maintaining the high precision required by today's sophisticated common rail systems.

With the rapid advancement of diesel engine technology, high-pressure common rail systems equipped with piezo injectors have become the mainstream choice across passenger cars, commercial trucks, agricultural machinery, construction equipment, and marine applications. The JZ-326B Pro is purpose-built to support these advanced systems, delivering a maximum rail pressure of 0–2700 Bar with a precision of ±5 Bar, ensuring stable, repeatable, and trustworthy diagnostic results for even the most demanding high-pressure injectors.

• Simultaneous 4–6 Injector Testing: Test four to six injectors at the same time to maximize workshop efficiency and reduce turnaround time.
• High-Pressure Piezo Injector Support: Specially designed for piezo injectors used in modern common rail diesel engines, with rail pressure up to 2700 Bar.
• Precise Rail Pressure Control: Pressure precision of 5 Bar ensures accurate simulation of real engine operating conditions.
• High-Efficiency Filtration: Filter precision below 5 μm protects the test bench and injectors from contamination, extending equipment service life.
• Gear Flow Sensor Metering: Reliable gear flow sensor technology delivers accurate fuel flow measurement for dependable injector performance evaluation.
• Stable Fuel Temperature Control: Maintains fuel temperature at 38–42 °C, replicating realistic operating conditions for consistent testing results.
• Convenient Internet Updates: The test bench supports firmware and software updates via the internet, keeping the system aligned with the latest injector data and testing procedures.
• Robust Industrial Construction: 750 kg net weight and a compact 1730*1250*1720 mm footprint with wooden board packaging ensure stability and safe worldwide shipping.

The JZ-326B Pro significantly reduces the time required for injector diagnosis and calibration. Instead of testing injectors one by one, workshops can now evaluate four to six injectors in a single cycle, cutting labor costs and increasing service capacity. Whether it is a quick leak test, spray pattern inspection, or full performance calibration, the test bench delivers the accuracy and repeatability that professional diesel service centers demand.

JZHY is committed to manufacturing excellence. With an annual production capacity of 1,500 pieces, every JZ-326B Pro test bench undergoes rigorous quality control to ensure long-term reliability in daily workshop use. The machine is designed for easy operation, stable performance, and low maintenance, making it an ideal investment for diesel injection service providers, vehicle repair shops, training institutions, and parts distributors worldwide.

Based in Wuxi City, Jiangsu Province — one of China's most important industrial and manufacturing hubs — JZHY specializes in the research, development, and production of diesel fuel injection testing equipment. With years of industry experience and a strong focus on innovation, JZHY serves customers around the globe with high-quality test benches, excellent after-sales support, and professional technical guidance.
