[MaddoxAnn]

Blue Whale engine common issues mainly include the following points: 1. Noise control: A common issue with the Blue Whale engine is that engine noise easily enters the cabin during high RPM ranges. 2. Fuel consumption: Compared to 1.4T engines of the same class, the fuel consumption of Changan's Blue Whale engine is 10%-20% higher. Advantages of the Blue Whale engine: 1. The Blue Whale NE1.4T comes from Changan's latest Blue Whale NE small and medium displacement high-efficiency engine platform. Currently, there are two models under development, the first being the already launched 1.4T turbocharged engine and 1.5T turbocharged engine. More models will be added to the development list in the future. 2. The Blue Whale NE1.4T has three main advantages. First, it has excellent power output parameters. Second, it achieves a thermal efficiency of up to 40%. Third, even with high-pressure direct injection technology, the engine still ensures an excellent sensory experience; such as vibration and noise control.
