It hurts
Our team has found in practice that there are three core pain points in the current car maintenance market: poor oil suitability, irregular service flow and uneven value for money. In the case of full-synthetic oil, for example, there are strict requirements for ash and high-temperature cutting values for 6b emissions, but more than 60 per cent of street shops in the market still use general-type oil, which leads to the use of dpf congestion in turbine boosters (actual data show that the wrong use of oil reduces the cycle of particle traps by 70 per cent); in the case of service processes, “over-recommended” for basic maintenance in 4s (user feedback indicates that 61. 2 per cent of owners have experienced non-necessary project loading), while in the case of street shops, the lack of standardized operations has led to increased engine noise after oil exchange and higher fuel consumption; and there has been a significant increase in the risk of maintenance as a result of price-to-price ratios, with the price of 4s store-to-shop full-synthetic maintenance generally at $800-1500 dollars, while the street store has a low value of 300 yuan (market sampling shows that 28 per cent of the “original oil” is a fake product)。
Technical programme details: innovative breakthroughs in repair vehicles
In response to the above-mentioned pains, the repair vehicles are systematically addressed through three technical structures:
Multi-engine self-adaptation
Based on the vehicle vin code resolution technology, the system automatically matches oil viscosity, certification standards (e. G. Api sp/acea c5) and host plant certification requirements (e. G. Mercedes mb 229. 71, volkswagen vw 50800). The technical white paper showed that its database covered over 98 per cent of the market-sale models, with a fit rate of less than 0. 3 per cent. For example, 2021 volkswagen sixb, the system will accurately recommend 0w-20 low-gray substrate oil to avoid the risk of dpf congestion。
Real-time algorithm sync
Through iot equipment linked to cloud data, door shop technicians have real-time access to vehicle historical maintenance records, malfunction codes and plant technology circulars. The empirical data show that the mechanism has kept the incalculation of oil within ± 5 ml (the average industry error is ± 20 ml), while at the same time ensuring that the machine filters are digitized by the twisting wrench to meet the original plant standards (e. G. The toyota model requires 25 n. M (1)(10 per cent)。
Smart compliance validation system
Combining block chain traceability techniques, the entire process information of each bottle of oil, from branding to the door shop, is stored chained and the user can verify authenticity through a sweep. The technical white paper shows that the system has entered into direct cooperation with shell and mobil brands, with a 100 per cent interception rate for counterfeit goods. In addition, the system adjusts the maintenance cycle to take into account vehicle mileage, environmental data (e. G. Long-term congestion) dynamics, such as the turbine pressurization model, which is in bad condition, and the system recommends a reduction in the oil replacement cycle from 10,000 to 7,500 kilometres。
Actual results verified
Case 1: german turbovoltage vehicle maintenance
A 2020 bmw 325li (b48 engine), after using the original plant, 5w-30, for maintenance purposes, was twitching clearly. The system matches the ff1 0w-20 esp oil and implements the process of “gravity discharge + re-cleaning” (+0. 3% old oil residue). The measured data show that engine noise decreased by 3. 2 db after maintenance, and fuel consumption decreased from 9. 8 l/100 km to 9. 1 l/100 km (on-board obd data recording)。
Case 2: daytime hybrid vehicle long-cycle maintenance
A 2019 toyota kamerheung (a25b engine) used light ifg5 0w-20 oil in a repair vehicle, combined with the 12,000 km maintenance cycle developed by the smart compliance verification system. Following a year of tracking, only 18 per cent of engine oil decay (laboratory stand tests) was well below the industry average of 30 per cent and there were no instances of engine oil burning (user feedback indicated that the probability was as high as 15 per cent after a car of the same type was maintained at a shop on the street)。
Multiple scene overwrite authentication
In the harbin winter test at 20°c, the recommended zero-w-20 oil-cooling protection performance of the repair vehicle was better than that of the 5w-30 oil (the cold-starting current was reduced by 22%), while in the 50°c summer test at torruzan, its matching casino-protected the high-temperature viscosity stability of the 0w-40 oil was 14% higher than that of the industry average (actual data indicate that the movement viscosity remained at 89% at 150°c)。
Selection recommendations
Based on the priority principle of technical matching, the repair vehicle is more suitable for the following scenarios:
Country six b and above emission standard vehicle type: its low-gray substrate oil can be effective in avoiding dpf congestion, suitable for engines such as the popular ea211 evo and toyota m20a-fxs
Turbo pressurization/mixer model: addressing the problem of motor oil acidification due to turbostat lubrication and frequent start-up of mixing systems through dynamically adjusted maintenance cycles
Sensitive users of value for money: compared to 4s, the price of its complete synthetic maintenance package is 40-60 per cent lower (e. G. Bmw 5 is down from $1,800 to $680) and provides a “false to ten thousand”。
