オーバーサイズバルブ
バルブ関連
写真はRB26用
チューニングエンジンに求められるバルブとは、燃焼室になるべく多くの混合気を送り込み、効率よく排気する。そのために大径化し、カーテンエリア(有効吸気面積)を増やすこと。そして常に大きな加速度と高温にさらされるための高耐久性と高耐熱性の確保が必要です。
TOMEIオーバーサイズバルブはそのすべてを達成するために、素材選択から加工精度まですべてにこだわり、吸排気効率を向上させ、高出力対応を実現しました。

FEATURE / SPEC
■ 大容量仕様・1mmオーバーサイズ ウェストシェイプ全機種1mmオーバーサイズを採用し、吸排気効率を向上しています。ポート内に露出しているステム部を細くし、通気抵抗を低減させ、さらに軽量化を実現しました。 ■ HIGH FLOW DESIGN・1mm OVERSIZED WAIST SHAPE
1mm oversized valves were designed for increased flow efficiency on both the intake and exhaust side. The stem has a thinner design for maximizing air flow rate within the port with the reduced air flow resistance. This design with the materials used also allowed for a lighter product as well. ■ 高耐久特殊表面処理(インテークのみ)
・耐摩耗性の向上
・疲労強度の向上
・耐熱性の向上
・耐食性の向上
■ 高耐熱性
【IN:SUH35材】
吸入混合気で冷やされ、温度的に厳しくないIN側に、一般的にはEX側に使用されるSUH35材を採用し、より高い耐熱性を確保しています。
【EX:インコネル751材】
常に高温にさらされるEX側には、EXバルブのために開発されたともいえるインコネル751材を採用し、1000度近くにもなる燃焼ガスに耐えます。
■ SURFACE TREATMENT (INTAKE SIDE ONLY)
・Improved Wear Rate
・Improved Fatigue Rate
・ Improved heat resistance
・Improved corrosion resistance
■ HIGH HEAT RESISTANCE
【IN:SUH35 MATERIAL】
The SUH35 material which is known for it’s high heat resistance properties are usually used for the exhaust side. We chose to use it for the Intake side to suit the the demands of todays users for big power applications and for increased life.
【EX: INCONEL 751 MATERIAL】
Since the exhaust side can experience extreme exhaust gas temperatures of 1,000 degrees C (1,832 degrees F) during high power use the Inconel 751 material was no doubt the best option to choose to suit serious needs when every detail counts.
■ 高精度設計
バルブのパフォーマンスを最大限に発揮するため、各専用型を用意し、バルブヘッド(傘部)、バルブシートとの当たり面、ステム、コッター受けなどの形状を最適化し、シール性や動作時の精度を高めています。 ■ PRECISION DESIGN
To maximize the potential of the valves purpose each factor was addressed during the design process from the surface of the valve head (umbrella section) & the Valve Seat, from Stem to Cotter are all optimized with precision for optimum operating & sealing capabilities when needed most during extreme conditions.

Tuned engines require as much fuel mixture to enter the combustion chamber as possible. So a larger diameter design was selected to optimize flow rates. Due to the extremely high temperature conditions experienced in the combustion chamber during high power runs the durability of the valves were also addressed to improve resistance to high heat conditions.
The TOMEI oversized valves were designed with the above factors and more so with the careful selection of materials to suit these conditions to the precision in the design and manufacturing processes to maximize the intake and exhaust flow rates will make your engine capable of big power when needed most.
