Engine-Related Products
These products contribute to regulating engine temperature and improving output and fuel efficiency.

Electric Water Pump for Engine Cooling
The pump feeds cooling water as needed by using the motor’s power to keep the engine at an appropriate temperature. The size and weight have been reduced by improving the shape and layout of the motor magnets.

Cooling Water Stop Valve
Improves performance of the heater and air conditioner by controlling the flow of the cooling water, thereby helping improve fuel efficiency.

Continuously Variable Capacity Oil Pump
Incorporates the world's first “internal gear mechanism.” With a unique gear tooth form, it continuously supplies the minimum oil necessary according to the engine's operating condition, contributing to improvement of fuel economy by reducing the demand on the engine driving the pump.

Variable Valve Timing
Optimal adjustment of engine intake and exhaust valve opening and shutting timing according to driving conditions contributes to reduced exhaust gas emissions and improved output and fuel efficiency.

Variable Intake Manifold
Feeds air to the engine and contributes to improvement of engine output and reduced fuel consumption by optimizing the intake pulsation and flow rate.

Exhaust Manifold and Converter
Directs the exhaust gas from the engine to the muffler. The structure integrated with the catalyst affords excellent exhaust gas purification performance.

Piston
Ensures both high strength and durability to cope with improved fuel efficiency and higher output in line with reduction in weight and friction. Installed in various engines.

Engine Front Module
Consolidates and integrates functional parts, such as a water pump and oil pump, as well as water and oil channels in the engine chain cover. Modularization achieves reduction in size and cost.
