Customer's Vehicle: Toyota HiAce (1KD-FTV Engine) – Hydrogen Gas Carbon Cleaning Service in Ishikawa
We recently performed a complete Hydrogen Gas Carbon Cleaning service on a customer's Toyota HiAce here in Ishikawa Prefecture!
Current Mileage: Approx. 355,800 km
Engine Type: 1KD-FTV (3,000cc Water-Cooled Inline 4-Cylinder DOHC Turbo, Electronically Controlled Common Rail Direct Injection)
Max Output: 106 kW (144 PS) / 3,400 rpm
Max Torque: 300 Nm (30.6 kg・m) / 1,200 - 3,200 rpm
The 1KD-FTV is a legendary engine known for its perfect balance of power and torque, effortlessly hauling heavy loads day in and day out.
The Goal: Engine Longevity & Preventive Maintenance
This particular service was requested while the vehicle was in for routine maintenance at Morishita Jidosha.
The owner loves this HiAce and wants to keep it running smoothly for many more years. With over 350k km on the odometer, this engine refresh is the perfect preventive measure.
To prevent common injector issues and extend the lifespan of the DPF (Diesel Particulate Filter), we also applied D-PINE MULTI CLEANER, a high-performance additive that effectively treats both components simultaneously.
Step-by-Step Service & Hydrogen Injection
On the Toyota HiAce, the air filter case is accessed from underneath the front bumper. We got under the vehicle to thoroughly inspect the air filter and check for any dirt build-up inside the housing.
After checking the engine sound, vibrations, exhaust pressure, and completing all pre-service prep, we began injecting the hydrogen gas.
We started carefully at a flow rate of 100 L/h, monitoring the engine’s condition closely before gradually increasing the hydrogen volume to ensure a safe and deep clean.

To ensure the D-PINE MULTI CLEANER spread quickly through the fuel system, we revved the engine a few times. At first, the engine's vibrations caused the vehicle's body to shake slightly. Knowing this could be a sign of dirty or clogged fuel injectors, we proceeded with the cleaning process while carefully monitoring the engine's live status.
5 Minutes In: The exhaust started becoming slightly damp, indicating that the carbon-cleaning process was beginning to take effect. When checking the exhaust pressure by placing a hand near the tailpipe, the pressure felt noticeably weak, and the airflow was uneven and intermittent. We continued the treatment to see how much we could improve these symptoms.
10 Minutes In: Water vapor began exiting the tailpipe—a classic sign that the hydrogen gas was successfully bonding with the carbon deposits and burning them off as steam. We fine-tuned the hydrogen flow rate and continued.
25 Minutes In: A major shift occurred. Both the engine noise and the harsh vibrations started to noticeably quiet down. At this optimal point, we locked in the hydrogen injection rate.
40 Minutes In: We revved the engine a few more times to check the progress. The slight body shake caused by engine vibration at the start of the service was completely gone! Furthermore, when checking the tailpipe again, the weak and intermittent exhaust pressure had dramatically improved—the exhaust flow was now smooth, consistent, and strong. From here, we adjusted the hydrogen input for the final deep clean.
50 Minutes In: Checking the tailpipe revealed that the exhaust gases had dried out, proving that the engine was now achieving highly efficient and complete combustion.
55 Minutes In: The exhaust pressure felt even more robust, perfectly steady, and healthy.
65 Minutes In: After 65 minutes of continuous treatment, we confirmed that the engine's idling, noise levels, and exhaust flow had completely stabilized. The engine refresh was a massive success, and we concluded the service.

※ 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.

An Update on the Vehicle: Since this HiAce immediately went back into the shop for further routine maintenance, we weren't able to get the owner's immediate driving impressions this time. However, we look forward to hearing their feedback as soon as they get back behind the wheel!
Why Carbon Cleaning Matters for Engine Longevity
Carbon build-up affects engine performance much more than most people realize. By removing these stubborn deposits through Hydrogen Carbon Cleaning, we instantly restore combustion efficiency.
This process delivers a massive chain reaction of benefits for your diesel engine:
Reduces Black Smoke & Soot: Keeps the engine and exhaust system much cleaner.
Improves Fuel Efficiency: Restores lost MPG/fuel economy.
Enhances Drivability: Delivers a noticeably smoother, more responsive throttle and acceleration.
Reduces Engine Stress: Lower stress means a significantly lower risk of unexpected mechanical failures.
Additionally, the D-PINE MULTI CLEANER we applied will continue to clean the system gradually as the vehicle is driven. This ongoing chemical cleaning provides long-term protection, effectively extending the lifespan of both the fuel injectors and the DPF (Diesel Particulate Filter). We explained how to use the remainder of the cleaner and handed it over to the owner for future use.
Conclusion: Invest in Preventive Maintenance
To keep this legendary 1KD-FTV engine running strong for another 300,000 km, we highly recommend scheduling regular hydrogen gas carbon cleaning as part of your routine maintenance checklist.
