What is Water Pump？
July 6th, 2022

The water pump is an important component of the car/truck cooling system. Its main purpose is to transport coolant and allow it to enter the corresponding water channels of the engine. Through cyclic activities, the exchange of coolant is achieved, and a large amount of thermal energy generated during the operation of the car engine is absorbed through cyclic flow, thereby reducing the temperature of the entire operating system of the car engine and achieving normal engine operation.

Operating conditions of Nox sensors
April 12th, 2022

When the ignition switch is turned on, the NOx sensor will heat up to 100 ℃ 2. Afterwards, wait for the ECM to send a temperature signal, and the DOC temperature of the front NOX sensor is 180 ℃ Rear NOx sensor SCR post temperature 200 ℃

What is Nox Sensor?
February 5th, 2022

The nitrogen oxygen sensor is a sensor used to detect nitrogen oxide compounds in diesel engine exhaust. The nitrogen oxygen sensor will upload the detected nitrogen oxide concentration data to the on-board computer (i.e. ECU), which will control the urea injection amount of the SCR system based on the data, thereby reducing nitrogen oxide emissions and achieving OBD monitoring of SCR components.

What is a throttle valve?
November 8th, 2021

The throttle valve is a controllable valve that controls the air entering the engine. After entering the intake pipe, the gas will be mixed with gasoline to become a combustible mixture, thus burning to form work. It is connected with the air filter on the top and the engine block on the bottom, which is called the throat of the automobile engine.
