Intake Manifold

The intake manifold is to evenly distribute intake air to each of the engine’s cylinders. This was conventionally made from metals such as aluminum, but by using plastics or magnesium as the material, a significant weight reduction has been achieved. In order to improve engine output from low speed to high speed and optimize fuel economy, a function for changing intake pipe length and chamber volume in response to driving conditions is introduced. In addition, intake resistance is low and is designed to be evenly distributed on each cylinder.

Throttle Body

The throttle body controls the engine load by adjusting the angle of the throttle valve. Conventional throttle valves used to have a mechanical connection to the accelerator, but now with the electronic control, it is possible to drive under optimum engine output conditions, and with this, an improvement of fuel consumption and better safety have been realised. Due to electronic control of the throttle body, cruise control function and Vehicle Stability control have been incorporated. Based on the input of the driver pressing the accelerator pedal (accelerator opening angle), the throttle valve controls the amount of intake air and sends it to intake manifold to adjust the RPM and the load of the engine for optimum driving condition of the vehicle.


Active Control Mount Solenoid (for VCM)

Active Control Mount (ACM) reduces the vibration that is transmitted to the vehicle body while the engine is idling and driving. This is achieved through signals received from the dedicated ECU. Cylinder deactivation for the reduction of exhaust gas and improved fuel consumption causes additional engine vibration. The ACM actuator minimises NVH by generating an opposite phase pulse in the ACM. We have done away with the bobbin maintaining the coil diameter with an unfused coil wire, and delivered high response and high thrust through the solid cast design of the coupler.



Spool Valve

Spool valve switches the oil passage of the rocker arm inside the engine based on the command from ECU to switch VTEC (Variable valve Timing and lift Electronic Control system). Flow consumption is reduced by using 3-way valve solenoid, yielding stable response even during low oil pressure operation. Products that meet customer needs such as lower cost version 2-way valve solenoid and complex / smaller size product utilizing experience of die cast technology and machining technology are provided.


Fuel Pipe Assembly

The Fuel Pipe Assembly incorporates the fuel distribution pipe and injectors to ensure proper assembly and guarantee against fuel leaks. The assembly of these parts also guard against contaminants introduced into these critical components. The optimum amount of the fuel that is sent from the fuel pump based on the driving conditions is injected into the intake manifold via the fuel injector from the command of the Electronic Control Unit (ECU). Due to tougher restrictions on exhaust gas in many countries, this started as a core part for optimum air / fuel mixture. Inexpensive and high precision product is provided by exact machining and assembly technology we gained through decades of carburetor work. We contribute to reduced emissions and low fuel consumption by utilizing optimum spray pattern to the engine through simulation technology, vehicle test, and cutting edge measurement technology.


EGR Valve

Returning an appropriate amount of the exhaust gases leaving the engine to the intake by means of the EGR valve in response to vehicle driving conditions lowers combustion temperatures and reduces NOx. In addition, supplying uninflammable gas in proportion to the cylinder capacity reduces engine pumping loss due to the throttle valve and improves fuel efficiency. Employing a linear solenoid drive system has delivered a wide range and high response.
