The Beidou Star has 4 models, including the 2019-1.4L-Manual Deluxe Edition, Classic Edition, and their facelifts, all equipped with a 97-horsepower engine. The NEDC fuel consumption is 5.1L per 100km, which is the official data. The fuel tank capacity of the Beidou Star is 42L. With a full tank, it can travel a distance of 42/5.1*100=823km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not releasing the throttle in advance when approaching a red light, will increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperature: When the engine block temperature is low during cold starts, the injected gasoline is less likely to atomize, requiring more gasoline to burn, thus increasing fuel consumption. Additionally, at low temperatures, the engine computer controls the engine to run at higher RPMs to warm up, which also increases fuel consumption. Excessive oil consumption: When excessive oil consumption is noticed, first check for oil leaks at the connections between the engine body and gear chamber cover, the large plate on the driving wheel side, rear cover, and cover housing. If there is a leak, observe whether the sealing gaskets at each connection are intact and replace any damaged ones. If the sealing gaskets are intact, check if the connecting screws at each part are loose. Oil loss: Long-term use of the engine can cause normal wear, or improper maintenance can lead to abnormal wear, both of which can create longitudinal scratches on the diesel engine's cylinder liner. If the cylinder diameter and piston side clearance exceed the specified values, the piston ring's tension decreases accordingly, leading to incomplete oil scraping. Alternatively, if the inner tension spring of the oil ring breaks at the oil ring's opening, incomplete oil scraping can cause the oil to participate in combustion, resulting in severe oil consumption symptoms. This manifests as difficulty starting the diesel engine, obvious blue smoke from the exhaust pipe, and severe oil spraying from the breather.
