Engine Devices


Intake Manifold

The intake manifold is to evenly distribute intake air to each of the engine’s cylinders. This was originally made of metal such as aluminum, but significant weight reductions have been achieved by changing the material to magnesium or plastic. The function to change the length of the air intake pipes and the volume of the chamber are added for engine output improvement and optimization of fuel consumption from low RPM to high RPM. The intake manifolds incorporate designs to minimize intake resistance and evenly distribute air to each cylinder.


Throttle Body

The throttle body controls the engine load by adjusting the angle of the throttle valve. Throttle valve used to have a mechanical connection to the accelerator, but now with the electronic control, it is possible to drive under optimum engine output condition, and improvement of fuel consumption and better safety have been realized. Due to electronic control of the throttle body, cruise control function and Vehicle Stability control have been incorporated.Based on the intention of the driver by 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) restrains the vibration that is conducted to the vehicle body while the engine is idling and driving through the signal from the exclusive ECU. Cylinder deactivation for the reduction of exhaust gas and improved fuel consumption causes additional engine vibration. The ACM actuator minimizes NVH by generating an opposite phase pulse in the ACM. High performance ACM is achieved by the bobbin to maintain the inside diameter of the coil is eliminated by non-fused coil wire, and the structure that molds coupler as one allows high response and high thrust force.


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.





Transmission Devices


Linear Solenoid Valve for AT

This is a control module for 6-speed automatic transmissions. The functions of four linear solenoid valves and three shift solenoids are integrated. As realizing light weight and small size, gear shift and clutch oil pressure are controlled very precisely to accommodate multiple steps of gear shifts. There is a line-up of optimum linear solenoids that suit the use such as high response type due to exhaust gas regulation and for fuel consumption.


Solenoid Valve

Gears are shifted within the Automatic Transmission by switching the oil passage based on the command from ECU and actuating the shift valve. Due to the fuel consumption regulations, the solenoid body was changed from steel to aluminum. The result was a reduction in weight. Additionally, the electromagnetic coil was reduced by increased efficiency through a change in the structure of the magnetic passage of the solenoid. The high thrust force solenoid specification allows a wide range of oil pressure control. The optimization of valve setting ensures oil flow even at low temperature, realizing high response switching of the shift valve.
