Is the Civic equipped with the Earth Dreams engine?

The Civic's engine belongs to the Earth Dreams series, utilizing Japanese technology and production lines, and is manufactured domestically. The Civic is equipped with two engine models: L15C7 and L15C8. The L15C7 engine delivers a maximum horsepower of 129 HP, a maximum power output of 95 kW at 5500-6000 rpm, and a peak torque of 180 N·m. The L15C8 engine offers a maximum horsepower of 182 HP, a maximum power output of 134 kW at 6000 rpm, and a peak torque of 240 N·m. For daily maintenance of the Civic's engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD-SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB-CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will deteriorate over time. After a certain mileage, its performance will degrade, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the relief valve, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing 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. These substances mix 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. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of both the radiator and the engine.
I understand the situation with the Honda Civic. Indeed, many models are equipped with Earth Dreams engines, especially those from the tenth generation onwards. Earth Dreams is a series of high-efficiency engine technologies introduced by Honda, focusing on fuel economy and low emissions, utilizing direct injection technology to reduce fuel consumption. In daily driving, the acceleration is smooth, the engine noise is low, and the reliability is good. However, not all Civics have this; earlier models might use traditional engines, so it's important to check the specific year when buying a used car. From my own research, the fuel-saving features of Earth Dreams are very cost-effective for ordinary family cars, and maintenance isn't complicated—just regular servicing is needed. Honda introduced this under environmental policies, innovating gasoline engine technology, which can be compared to Toyota's hybrid systems, but each has its own advantages.
