Whose technology is used in the Emgrand engine?

[LeGabrielle]

The engine used in the Emgrand is independently developed by Geely Emgrand, with its production base mainly located at Geely's engine plant in Ningbo. The engine model used in the Emgrand is the JLC-4G15B, with a maximum horsepower of 114 HP, a maximum power of 84 KW, a maximum power speed of 5600 rpm, and a maximum torque of 147 Nm. For daily maintenance of the Emgrand's engine, the following methods can be used: Use lubricating oil of the 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 according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. 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 becomes clogged and oil cannot pass through, the filter may burst or the bypass valve may open, allowing dirty oil to return 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 precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush 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 Emgrand for over three years now, using it for my daily commute, and I'm quite familiar with its engine. It's primarily based on Geely's in-house developed technology. They have their own R&D center in China, specializing in engine performance optimization. The overall power delivery is smooth with quick acceleration, and fuel consumption is well controlled, averaging around 6-7L per 100km for daily commuting. Although Geely has ties with Volvo, I've researched and found that the Emgrand's engine design was independently completed, with core technologies fully localized. It drives steadily and reliably with low noise. Many friends around me also drive Emgrands, and from our discussions, the engines rarely have issues, proving their solid quality. With regular maintenance and oil changes, the car still feels like new even after tens of thousands of kilometers, making it an economical and practical choice for daily commuting and family use.

Having worked in the auto repair industry for over a decade, I've serviced numerous Emgrand engine components. The core technology of Emgrand's engines lies in Geely's independently developed JL series, which prioritizes practicality and durability with a simple design for easy maintenance. Common repair issues include minor sensor or wiring problems, but the engine block itself has a low failure rate, demonstrating Geely's mature technology. Geely has dedicated factories in Zhejiang producing these engines. While they've adopted some quality standards after acquiring Volvo, the Emgrand platform remains independent. I recommend owners use genuine engine oil and perform regular maintenance, inspecting every 5,000 kilometers to prevent carbon buildup. This approach extends engine lifespan, ensures stable performance, and offers trustworthy cost-effectiveness.

Having observed the automotive industry for many years, Geely's development is quite remarkable. The core technology of the Emgrand engine belongs to Geely's independent research and development. They have made significant investments in R&D to create their own patented JL engine series, reflecting the progress of domestic automobiles. In its globalization efforts, Geely has integrated resources, such as absorbing Volvo's experience, but the design and production of the Emgrand engine are entirely localized in China, with intellectual property rights belonging to Geely. This independent strategy has enhanced brand competitiveness, reduced costs, and benefited consumers. In the future, hybrid technology may be introduced, but the robust foundational framework drives industry innovation, making it worth watching.
