L15BN is the engine model used in the 10th generation Accord, with a maximum horsepower of 194 hp, a maximum power of 143 KW, a maximum power speed of 5500 rpm, and a peak torque of 260 N.m. The engine of the 10th generation Accord is independently developed by the Honda Group and is one of the Earth Dreams engine series. For daily maintenance of the 10th generation Accord's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, select CB--CD grade diesel engine oil based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and keep the oil volume moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

I've been following Honda cars for many years. The 10th generation Accord uses a 1.5-liter turbocharged engine, model L15B series, such as the L15BE or L15BD commonly seen in North America and the Chinese market, delivering around 194 horsepower. It's fuel-efficient and smooth, making city driving very comfortable. The high-end version features a 2.0T engine, model K20C4, with 252 horsepower, offering fast acceleration, ideal for highway or spirited driving. The hybrid variant comes with a 2.0-liter Atkinson cycle engine, possibly named LFA or similar, paired with an electric motor, resulting in even lower fuel consumption and better environmental performance. In some regions like Europe or Asia, the engine models may have slight adjustments depending on emission standards. Overall, these engines are mature in technology, though occasional fuel system issues may arise, but regular maintenance should suffice. Launched in 2018, this model continues to receive updates, and specific details should be checked in the manual for the exact year and variant.

I just bought a 10th-generation Accord with a 1.5T engine model L15BD. The power is sufficient, making uphill driving at low speeds effortless, and it's very stable at high speeds. The fuel consumption is low, saving me a lot on gas money over a year. When I was buying the car, I learned that there were changes across different years. The minor updated version after 2017 might be called L15B7 or a similar model. The 2.0T K20C4 in the sport version is very powerful, but the 1.5T is practical enough for daily driving. The hybrid version's engine feels quieter, but I'm not sure about the specific model code. When driving, the focus is on reliable performance. Don’t just look at the model numbers—test driving will tell you the pros and cons.

When selling this car in the showroom, we highlight the diverse engine options of the 10th-generation Accord. The 1.5T models, such as the L15B7 from the L15B series, are fuel-efficient, smooth in power delivery, and ideal for commuting families. Upgrading to the 2.0T K20C4 offers strong acceleration, appealing to buyers who crave excitement. The hybrid version, equipped with a 2.0-liter engine, is eco-friendly and cost-effective. Overall sales data is strong, with positive customer feedback. When selecting configurations, consult the sales team for specific model variations.
