300TGI's engine is not imported, it is a domestically produced engine. The 15C4E is the engine model used in the 300TGI, with a maximum horsepower of 181 hp, a maximum power output of 133 KW, a maximum power speed of 5600 rpm, and a peak torque of 285 N.m. For the daily maintenance of the 300TGI engine, 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 of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's specified 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 according to usage conditions and maintain an appropriate oil level. 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 clogged and oil cannot pass through the filter element, it will either burst the filter element or open the safety valve, allowing oil to bypass through the bypass valve 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, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts separate out, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a 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.

The 300TGI engine is a commonly used power unit by Geely Auto. For enthusiasts with in-depth knowledge of automotive engines, it primarily refers to a 1.5-liter three-cylinder turbocharged gasoline engine, capable of delivering a maximum output power of 130 kW and a peak torque of around 255 Nm. This engine employs advanced direct fuel injection technology and a variable valve timing system, which enhance combustion efficiency and reduce fuel consumption. Thanks to its turbocharged design, it delivers robust power even at low RPMs, offering responsive performance in daily urban driving while mitigating the common vibration issues associated with traditional three-cylinder engines. Maintenance-wise, it's important to change the engine oil regularly, with inspections recommended every 5,000 kilometers or so to prevent carbon buildup from affecting its lifespan. Compared to competitors from Europe, America, and Japan, it holds advantages in both cost and reliability.

My Geely car is equipped with a 300TGI engine, which is a 1.5T three-cylinder powertrain. It accelerates smoothly, especially when overtaking on highways, with almost no lag. The fuel consumption is decent, around 8 to 9 liters per 100 km in the city, and it can drop to just over 6 liters on the highway, making it quite economical overall. Once, I drove it on a long-distance mountain road without any issues, but it's best to avoid frequent hard acceleration as the turbo can get a bit noisy under high load. In terms of reliability, after two years of driving, I haven’t encountered any major problems. I’d recommend other owners to stick to basic maintenance and change the air filter on time to extend its lifespan. This engine is well-suited for family use and offers great value for money.

In the automotive circle, 300TGI typically refers to Geely's 1.5T three-cylinder turbocharged engine, which delivers 130 kW of power - significantly higher than many Japanese counterparts like Honda's L15 of the same displacement, but slightly weaker than German Volkswagen's EA211 in torque response. It boasts good fuel economy and meets China's stringent National VI emission standards, with vibration control superior to older three-cylinder designs. Market positioning targets compact models like the Boyue, offering more affordable pricing than competitors, making it ideal for budget-conscious buyers. The downside is slightly more noticeable noise during high-speed acceleration compared to the quieter Japanese engines.

From the perspective of the Geely brand, the 300TGI engine is a core achievement of its independent research and development, with some technologies shared with Volvo, and it is applied to mainstream models such as the Boyue and Binyue. As a representative of domestic brand powertrains, it emphasizes balancing performance and environmental protection, with the development goal of reducing emissions and improving efficiency. In terms of reliability, user feedback indicates few electronic faults, and maintenance is convenient with easily accessible parts at low costs. It offers quick acceleration, but don't overlook daily oil checks to avoid high-temperature impacts.
