EGR cooler bypass valve
This switch valve bypasses the EGR cooler, to prevent over-cooling due to low-temperature EGR gas passing through the EGR cooler when starting the engine or at low temperatures, reducing HC and CO exhaust. Uses a butterfly valve, which is not affected by pressure before or after the valve, reducing size and weight.
Vacuum pumps
Cam-axis drive
Vacuum source for vacuum servo braking systems. We have a diverse line up of low-driving-torque pumps, depending on vehicle weight capacity and driven system, to reduce fuel consumption.
Motor driven
A vacuum pump developed for use in hybrid vehicle, electric vehicle, also idling stop equipped vehicle. It contributes to conserving fuel by operating only when needed.
* In development.
