Can 8bar Pressure Fuel Injector Cleaner Machine Simulate a 200bar Operating Condition?

Can 8bar Pressure Simulate a 200bar High-Pressure Operating Condition?

1. Actual Working Pressure of Fuel Injectors

• Diesel Common Rail Fuel Injectors: Typically operate at 200-250bar, or even higher (some National VI models can reach up to 300bar).
• Gasoline Direct Injection Fuel Injectors: Typically operate at around 50-150bar.

2. Can 8bar Pressure “Simulate” 200bar Injection Pressure?

Many people believe that to test the injector’s working pressure, a pressure above 200bar, similar to the actual engine operating conditions, is required for accurate testing. However, this is not the case.Most MRCARTOOL testing equipment uses 6-8bar air pressure or electric pump pressure to drive the testing fluid, not to perfectly replicate the high-pressure system inside the engine, but for the following two reasons:✅ Purpose 1: Check Spray Pattern, Flow Rate, and Clogging

• At 6-8 bar, technicians can directly observe injector clogging, uneven atomization, misaligned spray cone angles, and leakage using the fuel injector cleaning machine.
• The fuel injector cleaning machine can detect common power-loss issues – including poor spray patterns and partial clogging – that lead to increased fuel consumption at this pressure range.

✅ Purpose 2: Safe Testing Environment

• Using 200bar high pressure requires a specialized booster system, reinforced steel structure, and ultra-high-pressure seals. This not only drives up equipment costs but also poses safety risks for the user.
• The 8bar testing method chosen by MRCARTOOL allows for safe operation in home garages and repair shops, significantly lowering the user’s entry barrier.

Why Do We Not Recommend Consumers Choose a 200bar Pressure Fuel Injector Tester?

⚠️ 1. Extremely High Cost

• Requires a hydraulic or high-pressure air pump booster system.
• Pipelines and valves must be made from aerospace-grade materials (explosion-proof, leak-proof).
• High-pressure seals, precision instruments, and pressure relief protection systems are costly.
• The equipment price is at least 3-5 times that of a standard tester, making it completely uncost-effective for regular repair shops or DIY enthusiasts.

⚠️ 2. High Operational Risks

• A 200bar liquid pressure can easily puncture the skin, causing serious injuries.
• Professional protective clothing, safety goggles, and enclosed spaces are required during use.
• Any leakage or improper operation can result in severe consequences.

⚠️ 3. Limited Practical Value

• 200bar pressure only tests the dynamic response of high-pressure injectors under high pressure, but such issues typically arise from aging injector solenoid coils or ECU control anomalies, which are usually not solved through cleaning.
