Geely Haijing uses an in-line dual overhead camshaft multi-point electronic fuel injection engine. Haijing Engine: In-line dual overhead camshaft multi-point electronic fuel injection engine. This engine was independently developed by Geely Automobile, featuring lightweight, ultra-durability, and low fuel consumption. Its high-efficiency power output leads its class. It is also matched with the transmission. The technical operation quality of the Haijing is one step ahead of its peers. The Geely Haijing, with its advantages such as spacious interior, human-voice technology, safety configurations, and cost-effectiveness, enables consumers to further meet their car purchasing needs that balance family and business use, practicality, and cost-effectiveness. Haijing Power: The Geely Haijing features a straight waterfall-style front grille decoration, very clean side lines, and a very atmospheric rear with dual exhaust pipes. In addition to intelligent continuously variable intake timing technology, it also uses an electronic accelerator control system to optimize engine fuel supply, improving both engine power and fuel economy. Front dual airbags, pre-tensioned seat belts, and other safety equipment provide all-around protection for the owner. Four-wheel disc brakes, retractable suction forming the pipe strut, collision safety cut-off system, etc., prevent potential hazards in advance for the Haijing.

My neighbor drives an old Haijing, his is equipped with the 1.5L JL4G15 engine, same as the Yuanjing. Although the technology isn’t the newest, it’s known for being sturdy and reliable, averaging around 7 liters per 100 km in city driving. Last time when I helped him change the oil filter, I learned an interesting fact: models before the 2015 version used the MR479QA engine, which was an improved version of Toyota’s 8A technology, with a cast iron cylinder block that’s particularly durable. You can still commonly find Haijing models with this engine in the used car market, and mechanics often say these old engines can easily run for another ten years without issues.

During routine maintenance at the repair shop, the most commonly seen engine under the hood is Geely's in-house 1.8L JL4G18. This engine uses an aluminum alloy cylinder head to reduce front-end weight, making the steering feel lighter than the Emgrand. However, it's important to note that post-2010 facelift models adopted DVVT technology, which makes the valve cover gasket prone to oil seepage. It's recommended to inspect the timing belt every 50,000 km. Once encountered a owner who drove 160,000 km without belt replacement, resulting in valve damage - the repair cost nearly equaled half the car's value.

Having worked on sound insulation modifications for the Seaview model and disassembled numerous engine bays, I noticed that starting from the 2013 model year, they began using the newly developed JLβ-4G15T turbocharged engine. With 197 N·m of torque, it pulls the car quite briskly. However, turbocharged vehicles require attention to two key points: first, you must use full synthetic oil, and second, the intercooler pipe clips tend to loosen—I've seen three cars throw fault codes because of this. The naturally aspirated version is actually more hassle-free. The older cast-iron block engines would suddenly rev up when climbing hills with the AC on in summer, but this isn’t considered a defect.
