Engine external characteristic curve refers to the curve showing how power or torque changes with engine speed when measured at full load. Here are the details: 1. Engine characteristic curve: If the functional relationship between engine power, torque, fuel consumption rate and crankshaft speed is represented by a curve, this curve is called the engine characteristic curve. 2. Introduction: When the fuel supply mechanism reaches its maximum position, the total power characteristic is obtained, also known as the engine external characteristic. The characteristics obtained when the fuel supply adjustment mechanism is set to other positions are called partial speed characteristics.

What are the reasons for the poor cooling effect of the Sylphy's air conditioning?

The reasons for the poor cooling effect of the Sylphy's air conditioning: 1. The air conditioning filter is too dirty. It plays a role in filtering impurities. If it is not cleaned for a long time, a large amount of impurities will accumulate, and the air intake will decrease, resulting in poor cooling effect; 2. The condenser has poor heat dissipation. There are many heat dissipation fins on the condenser. If the surface of the heat dissipation fins is covered by some leaves or mud, the heat dissipation performance will be greatly reduced; 3. The compressor has insufficient refrigerant. The function of the refrigerant is to cool. If the car's refrigerant leaks, the cooling effect of the car's air conditioning will naturally not be very good. The Sylphy is a new strategic model launched globally by Nissan, featuring innovative design and advanced technology. In terms of body size, its length, width, and height are 4641mm, 1815mm, and 1447mm respectively.
