A DCV is an electromagnetic valve used for supplying gasoline vapors generated in the fuel tank to the engine based on the driving status, by controlling the flow rate in response to electrical signals. Our DCVs have been widely adopted by car manufacturers worldwide because of their excellent basic performance, including high accuracy, low noise, and high durability. Another reason for our DCVs’ success is our technical capabilities that enable speedy kaizen right after a failure has been identified, which is one aspect of “HAMADEN Quality.”
Duty Control Valve (DCV)
An electromagnetic valve to supply the gasoline vapor (HC) generated in a fuel tank to the engine according to the driving status, by controlling flow rate in response to electric signals.
Integrated Purge Valve (IPV)
IPV is one of Valve products like DCV3 so its structure and effects are same as DCV3s
VSV play a role of regaining a partial of exhausten gas before discharging into the environment to return to the combustion engine
The Sensor business domain detects the present and controls the future of vehicles.
We offer many different sensors that perform controlling and correction functions in various situations, including checking engine coolant temperature or intake air temperature, and operational detection of the accelerator pedal or electronic throttles. As the vehicle’s electronic control system becomes increasingly sophisticated, our products are needed in a wider array of applications.
Non Contact Sensor
This sensor detects the throttle valve position (rotation angle) and outputs the electric signals to the ECU. This sensor is assembled to the electric throttle valve.
Intake Air Temperature Sensor (IATS)
This sensor detects the temperature of intake air installed inside the air cleaner. According to the detected signals, ECU adjusts the fuel injection quantity after engine start.
This sensor detects the special vibration of the engine brock at the engine knocking condition and outputs the electric signals.
This coil is used for actuators of the ABS (Anti-lock Brake System), a system that enables a vehicle to stop safely in an emergency.
VTC play a role of fuel savings such as: Reducing energy loss in the process of intaken and emission gas, reducing emissions, and increase engine power
This coil is used for hydraulic solenoids that control optimal timing of intake/exhaust valves of the engine.
This coil is used for AT Shift Control Solenoid.
