Our Products
Air Flow Sensor
To meet increasingly stringent emission regulations, vehicles must precisely control the air-fuel ratio, which means that the ratio of air to fuel supplied to the engine must be precise. To achieve this goal, it is necessary to use an Air Flow Sensor. It is usually installed on the intake duct between the air filter and the throttle body, used to detect the real-time air volume intake into the engine, and then transmit the detected values to the Engine Control System, these values are used to calculate the ideal amount of the injected fuel, in order to control the proportion of air and fuel in the engine, so the stability and accuracy of the Air Flow Sensor determines the engine performance of Dynamic, Economy and Emission. In diesel engines, it is also used to regulate the recirculation of exhaust gases.
Electric Fuel Pump
The Electric Fuel Pump is a device that continuously sucks fuel out of the fuel tank and provides a specified pressure and flow of fuel to the fuel system, and is one of the components of the Electronic Fuel Injection (EFI) system. Based on its function, it can be seen that the performance of the Electric Fuel Pump will directly affect the working performance of the engine, also known as the ‘Heart’ of the Fuel supply system of the EFI engine. It’s basic working principle is that the DC motor is electrified to drive the rotor inside the pump housing to rotate at high speed, the lower section of the rotor shaft is combined with the internal hole section of the impeller, so that when the rotor rotates, the impeller is driven by the rotor shaft to rotate in the same direction, and the impeller high-speed rotation process causes vacuum low pressure in the fuel inlet part, and then the filtered fuel is sucked in form the inlet of the pump cover, and the sucked fuel is injected into the pump casing after being pressurized by the fuel pump impeller and then ejected through the outlet providing fuel with a certain pressure for the fuel system.
Canister Purge Valve
The Canister Purge Valve (CPV) is a vital part of the Evaporative Emission Control System (EVAP) that helps emission control and seals the fuel system of your vehicle to prevent harmful fuel vapors from entering the environment. In modern cars, the CPV is an electrically operated solenoid that controlled by ECU, it controls when and how much fuel vapor is released from the canister into the intake to reduce pollutant emissions and fuel consumption
