In the New Energy Era, Does the Walnut Blasting Machine Still Have a Market?

As the ownership of new energy vehicles continues to rise, many auto repair professionals are feeling anxious. Electric cars do not require engine carbon deposit cleaning, and the maintenance demand for traditional fuel-powered vehicles seems to be shrinking. Will the walnut blasting machine, which has long generated profits through carbon deposit cleaning, be eliminated by the times? On the contrary, the huge stock of fuel-powered vehicles and the unique carbon deposit problems of hybrid models ensure the long-term market demand for the walnut blasting machine. Moreover, they make this essential tool a “profit moat” for auto repair shops in the new energy era.

Huge Stock of Fuel-powered Vehicles Sustains a Strong Rigid Demand Market

It is true that the penetration rate of new energy vehicles is on the rise, but this does not mean fuel-powered vehicles will quickly disappear from the market. According to a report by BloombergNEF, the global ownership of new energy passenger vehicles will exceed 100 million by 2026. However, during the same period, fuel-powered vehicles will still dominate the market in terms of stock. In addition, although fuel-powered vehicles have passed their sales peak, their stock replacement cycle lasts as long as 10 to 15 years. For auto repair shops, countless fuel-powered vehicles will need regular carbon deposit cleaning for the next decade or more.

As we all know, carbon deposits are an inherent problem for fuel-powered vehicles. Low-speed driving and frequent starts and stops during daily commutes, as well as differences in fuel quality, will all cause carbon deposits to build up in key parts such as intake manifolds and intake and exhaust valves. This buildup will further lead to reduced power, soaring fuel consumption, and cold-start jitter. Recognized as an efficient and gentle carbon removal tool in the industry, the walnut blaster tool uses walnut shell abrasives with moderate hardness. It can completely strip stubborn carbon deposits without damaging precision engine components. It is a core piece of equipment for in-depth fuel-powered vehicle maintenance, and its status as a must-have tool has never changed.

Hybrid Models Have Stubborn Carbon Deposits, Spurring New Market Growth

More noteworthy than fuel-powered vehicles are the carbon deposit issues of hybrid models, including plug-in hybrids and extended-range electric vehicles. These models not only retain a complete engine system, but their unique operating modes also make carbon deposit problems more severe and frequent. This has directly created new demand for the walnut blasting equipment. Many auto repair professionals mistakenly believe that hybrid models use their engines less frequently, so there is no need to clean carbon deposits. However, the reality is quite the opposite.

According to disassembly data from international organizations, the carbon deposit thickness on the intake valves of 3-year-old hybrid models is about 1.8 times that of fuel-powered vehicles with the same mileage. After-sales data from top domestic 4S stores also shows that the engine failure rate of hybrid vehicles caused by carbon deposits is more than 30% higher than that of fuel-powered vehicles. The core reasons lie in the three key operating characteristics of hybrid models:

First, hybrid engines run intermittently with frequent cold starts and short operating cycles, keeping temperatures below the 70°C optimal level. JASO research shows this raises carbon deposit formation 2.3-fold, and short runs fail to burn deposits away, causing hardening layers. Daily pure-electric commuting leaves engines idle for days or weeks. Stagnant fuel oxidizes into gummy carbon that clings tightly to components on restart. Most hybrids use GDI engines with tiny, cleanliness-sensitive nozzles. Carbon deposits hurt power and fuel efficiency, and may distort fuel atomization, triggering severe engine issues.

More importantly, the carbon deposits in hybrid models are mostly low-temperature residual carbon deposits. They are much harder to clean than the high-temperature sintered carbon deposits in traditional fuel-powered vehicles. Traditional methods such as chemical injection cleaning have limited effects. In contrast, the walnut blasting machine uses high-pressure airflow to drive walnut sand particles. It precisely impacts key parts like intake manifolds and intake and exhaust valves, completely stripping away stubborn carbon deposits. The entire process requires no disassembly and will not damage precision engine components, making it the optimal solution for cleaning carbon deposits in hybrid models. In the actual maintenance of models such as the Lexus ES300h and Toyota Camry Hybrid, walnut blasting has become a necessary in-depth maintenance item. Many car owners take the initiative to have carbon deposits cleaned at repair shops after driving 20,000 to 30,000 kilometers.

Versatile and Profitable, It Remains a Core Equipment for Auto Repair Shops

In the new energy era, the core competitiveness of auto repair shops lies in accurately capturing the maintenance needs of the existing stock of fuel-powered vehicles and the growing number of hybrid models. The versatility of the walnut blasting equipment fully meets this market demand. Whether it is regular carbon deposit cleaning for traditional fuel-powered vehicles or tackling stubborn carbon deposits in hybrid models, it can meet the cleaning needs of mainstream models such as Audi, BMW, Mercedes-Benz, Toyota, and Lexus when paired with corresponding adapters. Models like the AUTOOL HTS678 walnut blaster tool come with 23 specialized adapters, covering most vehicle models available on the market.

From a profitability perspective, new energy vehicles have few maintenance items and low unit prices. Many auto repair shops are struggling with a lack of business. On the other hand, carbon deposit cleaning is a high-frequency, high-demand service for both fuel-powered and hybrid vehicles. It features high unit prices and easy operation, effectively boosting the revenue and average transaction value of auto repair shops. For auto repair professionals, the walnut blasting machine is not an outdated device on the verge of elimination. Instead, it is a key tool to cope with the impact of new energy vehicles and unlock profits in the existing market.
