Variable intake manifold with an integrated rotary valve

High output is achieved by switching intake ports according to driving conditions

• Cost and weight are reduced by applying resin intake manifolds and variable valves
• Engine output is improved by optimally controlling air flow to cylinder chambers by switching passages having different length
• To improve engine output, a rotary valve, which has low intake pressure loss, is used for a variable intake portion

Engine Front Module

Realization of the Lightweight and Fuel-efficient Engine Front Module by Integrating Parts and Functions

• The weight is reduced by die-casting large-sized products. It contributes to improvement of fuel consumption. Strength is also improved.
• Modularizing the accessory brackets reduces the number of engine parts in total

Oil Pumps

High-efficiency Oil Pumps Developed from the Engine System Requirements

• Wide variety of oil pumps developed from the design and evaluation techniques, that can optimize the drive systems and installation type in each engine
• Development of the unique tooth profile of rotors, which allow the oil pump to be low friction and low noise

Water Pumps

High-reliability Water Pump Developed from the Engine System Requirements

• The material of mechanical seals having a large role to play in preventing cooling water leakage changed to silicon carbide (SiC) from alumina. Thereby heating in the sliding portion and wear of the sliding member are prevented. Sealability is also improved.
• The triple lip seal is adopted as the bearing seal on the rear side. The bearing damage caused by which cooling water leaking from the mechanical seal infiltrates in the bearing, is prevented
