My RX-8　Engine broken‐down & rebuilt
RX-8が一般道走行中にエンジンブローしたので、レボリューションさんでオーバーホールを行いました。ブローしたエンジン内部は再利用が可能な部品がほとんどないほど酷いことに...。オイル管理はそこそこしているつもりでしたが、全くできていなかったことが、エンジンの中身を自分の目で見て分かりました。走行距離は約７０，０００Kmでした。 【オーバーホールの内容】 ・ローターランド加工 ・ローター重量合わせ ・メタル合わせ ・アペックスシール溝修正 ・コーナーシール溝修正 ・サイドシール溝修正 ・プロトスペックサイドシール ・エキセンラッピング ・ポート面取り加工 ・ポート段付き修正 ・インジェクタ吐出量合わせ

Part 7: My 76 Mazda RX-5 Cosmo Restoration - Intake and Exhaust Porting
Has it been nearly a month since my last episode? Wow, time does indeed fly. I've been quite busy preparing to build the engine. So in part 7, I cover the intake and Exhaust porting. The engine is being built with GSL-SE 6 port plates and the Cosmo rotor housings as the basis for a 6 port turbo setup. This port job is fairly conservative, only opening up the primary ports a little and bringing the Exhaust ports close to 2nd gen RX-7 specs. The goal is to maintain fuel economy, low and midrange torque, and idle quality. This episode covers everything involved in porting including: marking out the new ports, grinding the port shape, smoothing the bowls, smoothing port to runner transitions, smoothing the runners, grinding and blending the Exhaust ports.

Part 3: My 76 RX-5 Cosmo Restoration - Rotary Engine Disassembly And Cleaning
Part 3 of my Cosmo restoration shows disassembly of the 4 port 13B rotary engine and the beginning of the long process of cleaning the internal engine parts. At first I was quite worried about the condition of the engine after looking through the Exhaust ports, but as soon as I opened it up I was pleasantly surprised.

MAZDA RX7 Rotary Engine Failures
MAZDA RX7 Rotary Engine Failures MAZDA RX7 rotary engines are strong and displace a lot of power for their size. Traditionally, carbon deposits and heat are their biggest enemies. Rotary engines run with a huge temperature differential, meaning that one side of the engine runs cooler that the combustion side (side with the park plugs). As a rule, cooling system damage should be avoided at all costs. Learn how these issues affect rotary engines and what kind of damage is done to them when they really fail. Presented using advanced software CG animation technology to help you understand. Part of our Automotive Technology Rotary Wankel engines and MAZDA RX7-RX8 series shown here on this channel.

Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together. There was a lot of trial and error as jury-rigged parts were improvised and revised, leaks were identified and plugged, and byzantine electrical diagrams were decoded. It still does not run smoothly, as there likely is a problem with the intake system that has prevented smooth timing at idle. But she runs! lots of people wanted to know where the E-shaft came from: it was custom ordered from a shop in New Zealand.

The Mazda Rotary Engine Part 1
Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the Rotary engine works with comparisons to the Piston Engine. Also shows the Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or 110S). Originates from the late 60's.
