We recently had the pleasure of performing a hydrogen gas carbon cleaning service on a customer's vehicle here in Shimane Prefecture.

[Vehicle Specifications]

Model: Mazda CX-3
Engine: SKYACTIV-D S8-DPTS Type / 1,756 cc Water-Cooled Inline 4-Cylinder DOHC 16-Valve Diesel Turbo Engine
Current Mileage: Approx. 145,000 km
Max Output: 130 ps (95 kW) @ 4,000 rpm
Max Torque: 27.5 kg·m (270 N·m) @ 1,600–2,600 rpm

This vehicle features Mazda’s proud SKYACTIV diesel technology.

As the mileage on this CX-3 reached around 145,000 km, the owner noticed that the DPF (Diesel Particulate Filter) regeneration cycle was becoming noticeably shorter. To restore engine performance and responsiveness, the customer requested our Hydrogen Gas Carbon Cleaning Service for a full engine refresh.

Additionally, for long-term maintenance and preventative care—covering everything from the fuel tank and injector tips to preventing clogs in the DPF and EGR valve—we also performed a treatment using Deepine Multi-Cleaner.

First, we accurately measured the specified dosage of Deepine Multi-Cleaner and added it directly into the fuel tank.

After completing initial safety checks—including engine noise, idle vibration, and exhaust gas conditions—we began injecting the hydrogen gas.

We started at an initial flow rate of 100 ml/h, carefully monitoring the engine's response and parameters while gradually increasing the hydrogen output.

[ During-Service Impressions & Real-Time Progress ]

To help the Deepine Multi-Cleaner circulate more quickly throughout the system, we blipped the throttle a few times.

While doing so, we checked the tachometer and noticed that the needle flickered slightly as it dropped from around 2,500 rpm down to idle.

5 Minutes In: Checking the exhaust tailpipe by hand, a slight amount of moisture was detected. The exhaust pressure felt a bit weak, and the exhaust flow showed irregular pulsations. We proceeded with the carbon cleaning process, gradually adjusting the hydrogen injection rate while monitoring how these symptoms would improve.
10 Minutes In: Steam began to emerge from the exhaust tip.
15 Minutes In: Water droplets started forming at the exhaust outlet.
20 Minutes In: Engine noise and vibration noticeably decreased. We locked in the hydrogen injection rate to maintain this optimal treatment state.
40 Minutes In: Checking the exhaust tailpipe again, the previously weak exhaust pressure and pulsing flow had improved significantly. The exhaust gas temperature also rose, indicating that carbon combustion and decarbonization were actively progressing. We blipped the throttle once more to check the tachometer: the needle drop from 2,500 rpm—which previously flickered—was now much smoother, and the idle return had normalized. We continued the treatment with further fine adjustments to the hydrogen flow.
55 Minutes In: The moisture around the exhaust tip began to dry out.
65 Minutes In: After making final adjustments to the hydrogen injection rate, we confirmed that the idling state, engine noise, vibration, and exhaust behavior were all fully stabilized.

With these results achieved, the hydrogen carbon cleaning process was successfully completed. The remaining Deepine Multi-Cleaner was handed over to the customer along with a clear explanation of how to use it for future maintenance.

※ Product Focus: D-PINE MULTI CLEANER

As shown in the reference image below, the D-PINE MULTI CLEANER used in this service is highly effective for treating the most notorious weak points of clean diesel engines: the fuel lines (including injectors), DPF, EGR system, and the EGR cooler.

While it comes with a slightly premium price tag, a single bottle contains enough capacity for two complete treatments in standard-sized passenger vehicles. This makes it an incredibly cost-effective solution for preventing carbon clogging and sudden component failures.

Replacing or repairing clogged diesel injectors or a blocked DPF can lead to astronomically high repair bills. That is why we highly recommend using this cleaner as a regular part of your preventive maintenance routine to save your engine—and your wallet—from major issues down the road.

[ Customer Post-Service Review / Testimonial ] ↓↓↓

"The engine feel has improved tremendously, and the DPF regeneration cycle—which I was quite concerned about—has become significantly longer."
"On a recent trip back home to Shimane, my fuel consumption reached 24 km/L, which is roughly a 3 km/L improvement compared to before the service!"
"Overall, the improvement was noticeable enough that I'm truly glad I went ahead with this service. It seems regular maintenance like this will keep the car in peak condition, so I’ll definitely be back again!"

[ Why Mazda SKYACTIV-D Engines Need Carbon Cleaning ]

We frequently receive inquiries and service requests for Mazda SKYACTIV-D clean diesel engines.

In particular, once these vehicles pass 70,000 km, many owners begin to worry about the health of their DPF (Diesel Particulate Filter) and fuel injectors.

Modern clean diesel vehicles are equipped with DPF systems to comply with strict emissions regulations, as well as EGR (Exhaust Gas Recirculation) systems designed to improve fuel efficiency and re-use exhaust gas. However, these components naturally reduce exhaust efficiency over time and increase the overall load placed on the engine.

[ Our Solution: Hydrogen Carbon Cleaning & Preventative Maintenance ]

To resolve and prevent these issues, our shop performs a specialized Hydrogen Gas Carbon Cleaning Service. This process removes carbon deposits inside the combustion chamber, improves overall combustion and exhaust efficiency, and prevents soot (carbon) from flowing downstream.

For owners concerned about the fuel system (including injectors), DPF, or EGR valve, we strongly recommend combining the service with our Multi-Cleaner treatment.

[ Prevent Costly Repairs Before the DPF Warning Light Turns On ]

Important Note: Once the DPF warning light turns on and the filter becomes severely clogged, neither Hydrogen Gas Carbon Cleaning nor additive treatments like Multi-Cleaner can fully resolve the issue.

Replacing or repairing clogged DPFs, EGR valves, or injectors can be extremely expensive. We strongly advise proactive maintenance before these problems occur. Taking proper care of your car pays off in long-term performance and reliability!

Clean diesel cars offer fantastic fuel economy, powerful torque for an enjoyable drive, and lower running costs compared to gasoline vehicles. With regular maintenance, you can enjoy your vehicle for many years to come.
