What are the common issues with the Blue Whale engine?

The common issues with the Blue Whale engine include noticeable engine noise entering the cabin at high RPMs and a relatively stiff chassis. The 1.4T variant of the Blue Whale engine delivers a maximum horsepower of 158 HP and a peak torque of 260 N·m, which offers competitive performance among engines of the same displacement. Below is additional information: The Blue Whale NE1.4T high-pressure direct injection engine features a fully variable displacement oil pump + controllable PCJ, enabling precise pressure regulation based on different engine load conditions and on-demand supply. This achieves closed-loop pressure control, reducing power consumption by approximately 3%.

I've been driving a Changan SUV with the Blue Core engine for three years now. Overall, it has sufficient power, but there are several common issues frequently discussed in our car owners' group. First is the fuel consumption problem - while officially claimed to be fuel-efficient, the gauge drops noticeably fast when driving on highways with AC on, requiring frequent refueling. Second is the loud engine noise, especially that annoying humming sound during low-speed acceleration. Third, the turbocharger responds a bit slowly - there's a slight delay when overtaking before the power kicks in. A few owners also mentioned oil leaks due to seal aging after long-term use. My suggestion is to regularly check engine oil and filters during maintenance to prolong its lifespan. These issues vary among drivers - gentler driving habits might result in fewer problems.

I bought a Changan car equipped with the Blue Whale engine, and within the first year, I noticed some common issues that were quite frustrating. The most obvious one is the strong engine vibration, with a slight shaking sensation in the steering wheel during cold starts. The fuel consumption also didn't meet the advertised expectations, especially in traffic jams where it burned faster. Some owners also reported noise issues, with louder sounds during acceleration compared to similar-class vehicles. Although the acceleration performance isn't bad, the minor issues are a bit more frequent, and I make monthly visits to the repair shop to have the electrical circuits and turbo components checked. Overall, the car is decent, but these problems make daily driving a bit annoying.

As an engine enthusiast, after studying the Blue Whale series, I found that common issues mainly focus on three aspects. First, turbo lag—the slow response of the turbocharger affects acceleration performance. Second, insufficient fuel efficiency optimization—ECU calibration tends to result in higher fuel consumption in urban driving. Third, weak vibration and noise control—compared to international brand engines, there is room for improvement in vibration damping design. Long-term use may pose a risk of oil leakage, but overall reliability is acceptable.

Through my extensive experience in servicing Changan vehicle owners, the common issues with the Blue Whale engine are quite typical. Most complaints revolve around higher-than-expected fuel consumption, typically 1-2 liters more than anticipated; noticeable engine noise, often traced to exhaust system design flaws; and excessive vibration affecting ride comfort, frequently caused by loose or unstable mounting brackets. Turbocharged versions commonly exhibit throttle response lag, requiring inspection of boost components. Other minor issues like oil leaks from aging seals have also been reported. I recommend owners perform comprehensive maintenance every six months, including software updates for fuel consumption optimization.
