What kind of lubricating oil should be added to the motor?

Generally speaking, the motor of a car does not require lubricating oil, but the motor bearings may need grease. Below is some relevant knowledge about car motors: Performance requirements of car motors: The characteristics of car driving include frequent starting, acceleration, deceleration, and stopping. High torque is required at low speeds or when climbing hills, while low torque is needed at high speeds. The motor's speed range should meet the requirements from zero to the maximum driving speed of the car, meaning the motor must have high specific power and power density. Working principle of car motors: The motor is the component that converts the battery's electrical energy into mechanical energy to drive the rotation of the electric vehicle's wheels.

What does kW mean in cars?

kW is the unit of power. The related introduction of power is as follows: Introduction to power: Power is an important performance parameter of a car engine. Power is used to measure how much work the engine does per unit of time. The greater the power, the stronger the engine performance, but the higher the fuel consumption. Power is related to the engine's speed and torque. Torque is another important performance parameter of the engine, which measures the maximum moment the engine can output in one cycle of work. Introduction to increasing power: The most direct and simplest way to increase engine power is turbocharging technology. A car engine uses a mixture of air and fuel as its fuel. If the intake air volume and fuel injection volume are increased, it is equivalent to increasing the amount of fuel. With more fuel, the energy released during each combustion also increases, thereby improving the engine's power.

What is the reason why the car heater is warm at idle but not when driving?

The reasons why the car heater is warm at idle but not when driving are: 1. The thermostat is always open or opens too early, causing the engine coolant to enter the large circulation for cooling before the water temperature rises; 2. The electric cooling fan is constantly running; 3. The heater core or coolant passages are blocked, preventing the heated antifreeze from circulating into the heater core; 4. The heater control valve cannot open normally. The functions of the car air conditioning system are: 1. To achieve cooling effect through the continuous phase change cycle of refrigerant; 2. To remove dust, odors, smoke, and toxic gases from the air inside the car, making the cabin air fresher, and to humidify the cabin air to increase its relative humidity.
