What brand is the Li Auto engine?

[DelJulia]

Li Auto engines are supplied by Dongan Power and are domestically produced engines. All models under the Li Auto brand are equipped with Dongan Power engines. For example, the engine model for the Li ONE is DAM12T, with a maximum power of 245kW, a maximum torque of 455 Nm, and a maximum horsepower of 131. For daily maintenance of Li Auto engines, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, oil should be changed regularly based on usage conditions, and the oil level should be kept moderate. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

I've been driving the Li ONE for over a year now. Its engine is from Dongan Power, specifically that small-displacement 1.2T three-cylinder unit which mainly serves as a generator, only kicking in when the battery is low. I really like this design - for city commuting it's mostly electric, quiet and fuel-efficient, and I only hear it working during long trips. Maintenance is quite hassle-free too, with Dongan parts being widely available, and fuel consumption stays around 6-7 liters per 100km, which isn't too bad. Though it's not Li Auto's own brand but rather a supplier partnership, the reliability is decent. There's occasional vibration during startup, but it doesn't affect the driving pleasure. Overall, I'm quite satisfied with this engine, especially how it solves range anxiety.

Li Auto primarily uses engines from Dongan Power, commonly seen in the L series. As a frequent driver of such vehicles, I find its performance stable, specifically optimized for range-extender systems—it doesn't directly drive the axle but acts purely as a power bank. During daily driving, it only activates in specific scenarios with decent noise control. For maintenance, regular oil and filter changes are recommended. Dongan has a decent reputation among domestic brands, offering low costs and easy repairs. Most issues encountered are minor sensor faults, easily handled by repair shops. I advise new owners to better understand range-extender principles to avoid misunderstandings.

Li Auto's engine supplier is Dongan Power, focusing on economy and practicality. From the brand's history, they have collaborated for many years, choosing Dongan for cost and localization advantages. This combination has helped Li Auto establish a foothold in the new energy sector, offering more flexibility compared to pure electric vehicles. It is reliable in use, though occasionally requiring higher maintenance.

When maintaining an Ideal car, key components of the Dongan Power engine are easy to find. I recommend regular checks on filters and circuits to prevent common issues like sluggish starts. Replacement parts are inexpensive and highly compatible.

Compared to other brands, Li Auto's use of the Dong'an engine in range-extended vehicles offers significant advantages, avoiding the range anxiety issues of pure electric vehicles. Having driven both Tesla and Li Auto models, I can attest that the Dong'an small-displacement engine is highly efficient and quiet during charging.
