Changan Uni-K's actual fuel consumption is only 0.8L. Below is relevant information about fuel consumption: Reducing vehicle weight: There is a proportional relationship between vehicle weight and fuel consumption. It is said that for every 10% reduction in vehicle weight, fuel consumption will correspondingly decrease by several percentage points. Improving engine thermal efficiency: The thermal efficiency of a typical gasoline engine (i.e., the proportion of fuel converted into useful work) reaches over 30%, while diesel engines exceed 40%. This is the main reason why diesel engines have lower fuel consumption than gasoline engines. Smaller body drag coefficient will significantly reduce fuel consumption. These two factors also have a proportional relationship.

Is it necessary to install an engine guard when buying a new car?

It is necessary to install an engine guard when buying a new car. The functions of an engine guard include: 1. Preventing mud from covering the engine, which could lead to poor engine cooling; 2. Protecting the engine from impacts caused by uneven road surfaces during driving, thereby preventing engine damage; 3. Extending the engine's service life by avoiding damage caused by external factors during travel, which could result in car breakdowns; 4. Keeping the engine compartment clean and preventing road water and dust from entering the engine compartment. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning and expanding gas within a sealed cylinder, thereby pushing the piston to perform work.
