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.

O2 Sensor Test Quick-Fix
CATALOG: http://www.autodiagnosticsandpublishing.com/Software_Catalog.html O2 Sensor Test Quick-Fix The Oxygen sensor has a reactive Zirconia and Platinum element that senses Oxygen in the Exhaust. Here are the facts about Oxygen sensors. 1) The O2 sensor value is used by the ECM in maintaining the Stoichiometric air/fuel ratio of 14.7:1. 2) The O2 sensor generates its own voltage. 3) The O2 sensor needs to cross the 450 milli Volts or 0.45 volts when it cycles, assuming the mixture is at 14.7 to 1. 4) O2 sensors need to cycle between 0.1 and 0.9 volts for the mixture to be considered at Stoichiometry. This value is considered perfect, so some deviation is posible. 5) If the O2 sensor is working properly, the Fuel-Trims should be at between -10% and +10%, and in Closed-Loop. 6) If there's an ignition misfire, and unburnt fuel exits the Exhaust, the O2 sensor will see the Oxygen only, not the raw fuel, thereby, signaling the ECM that the mixture is LEAN or the opposite. 7) The O2 sensor doesn't measure Oxygen directly, by measures the difference between Exhaust and outside air Oxygen content. 8) Silicone is the biggest enemy of the O2 sensor. So, do not use silicone paste on the intake manifold. 9) The O2 sensor signal is also needed by most catalytic converter to reduce harmful emissions. 10) To test the O2 sensor, use a volt-meter or better yet, a graphing volt-meter. Measure between sensor ground and O2 sensor signal wire. Regardless of whether the engine is running properly or not, snap the throttle, the O2 signal should reach at least 0.8 to 0.2 volts. Remember, if the engine is running fine, the Fuel-Trims should be between -10% and +10%, the O2 signal should cycle once every second and cross the 450 mV value, and finally, reach between 0.8 and 0.2 volts.





MAZDA RX7 Rotary Engine Combustion Cycle
MAZDA RX7 Rotary Engine Combustion Cycle The MAZDA RX7 rotary or Wankel engine's cycle of operation is somewhat similar to a regular piston engine, but only in name. The four stages to a full rotary engine cycle are intake, compression, ignition and Exhaust, but they all happen in a continuous flowing movement, hence the name rotary. MAZDA perfected the rotary engine design, but its basic operation is the same for all rotaries. In this video you'll see in detail the exact operating modes for a rotary engine. These engines in the past suffered from various design issues, but today's rotary engines are a far cry from the olden days. In spite of that, MAZDA was able to win many races starting in the 70's and throughout the 90's. Learn the cycles of operation of the rotary engine.

MAZDA RX7 Rotary Engine, How It Works
MAZDA RX7 Rotary Engine, How It Works https://twitter.com/#!/ADPEducation http://www.facebook.com/pages/Automotive-Diagnostics-and-Publishing/3669698 48008 The MAZDA RX7 rotary or Wankel engine is a marvel of engineering. It has won more races than any other vehicle in its class. Rotary engines develop a great deal of power for their weight (power to weight ratio). They're also able to develop high RPM bursts like no other internal combustion engine. Learn the details of it operation, how the rotor transfers power to the output shaft, what it the stationary gear set, what is the rotor to output shaft ration and relationship. Get all the specifics on the rotary engine's operation here in this video. Presented using advanced software CG animation technology to help you understand.

Knock Sensor Quick-Fix
SOFTWARE CATALOG: http://www.autodiagnosticsandpublishing.com/Software_Catalog.html Knock Sensor Quick-Fix The knock sensor is used by the ECM to fine tune ignition timing. A faulty knock sensor will cause a faulty code to set, and may also cause ignition timing to be skewed. Lack of power may also be another symptom. These are the knock sensor facts. 1) The knock sensor is a type of microphone, screwed to the engine block or manifold. 2) It is a piezo electric or crystal component. 3) Knock sensors produce their own electricity. 4) A knock sensor produces alternating or AC current. 5) The sensor is tuned to between 6 to 9 thousand Hertz, which is the pinging frequency, so as not to confuse the ECM. 6) There are two types of knock sensors, the older wide band, and the newer resonant or tuned knock sensor. 7) You test these two types of sensors differently. 8) To test the wide band knock sensor, with engine and key off, probe with a volt meter set to AC, between battery ground and the knock sensor signal wire. Then, light tap near the knock sensor using an extension or back of the ratchet wrench. 9) The resonant newer style knock sensor will not react to engine tap. These sensors are tuned only to an engine ping. 10) To test these sensors, connect the volt meter as before, start the engine, then remove the fuel pump relay or fuse. As the vehicle is starved for fuel, pre-load the engine a bit by putting the car in gear, foot on brake, and accelerate a bit. The fuel starved engine will ping. On both tests you should see an AC voltage outputted. That concludes the knock sensor Quick-Fix.





CONCEPT WANKEL MOTOR PT1.mp4
http://www.baylissgraphics.com/blog/ Part 1 of the 25 minute animation of the Concept Wankel Motor was produced using CAD data from the customer with texts and storyboard written and spoken by myself using Cinema 4D. The final version including all the spoken texts was hurriedly finished overnight after some last minute unexpected changes by the customer and delivered 200km away from my offices in Germany for an exhibition. This meant that the 25 minute animation was not completed to my full satisfaction, nor was it in the quality desired by myself. The animation was in 768x576 pixels for showing on DVD.

Rotary Engine Breakthrough?
The Wankel engine always held out a lot of promise, but never was able to fully deliver on those promises. It was never very fuel efficient, and the Exhaust temperatures were very high. But now an independent car tech thinks he has stumbled onto what held that engine back. Get more video everyday at http://autoline.tv

20B rotary RX-7 Spirit R: The Ultimate Street Mazda
Built by Promaz Automotive, we think it's hard to go past Steve's wicked Series 8 FD RX-7 if rotaries are your game. Limited to around 1500 unit's, the Spirit R was the last of the RX-7's and featured a lot of upgraded factory parts as well as a low 1100kg weight. Now powered by a lethal Promaz triple rotor 20B extend port rotary engine, power is aided by a Garrett GT42R turbo and MicroTech fuel system and transmitted through an Albins 5-speed gearbox and KAAZ rear end [ http://www.promaz.com.au ]. http://www.facebook.com/fullBoostcomau http://www.youtube.com/user/fullBoostcomau http://www.fullBoost.com.au
