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.

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.

VGTs like most other turbo units tend to have a high failure rate if not cared for correctly. In this video we expose some of the failures associated with VGTs specifically and what can be done to prevent it. Rebuilding a VGT is no easy task, so it is best to prevent damage by applying a few simple rules. Presented using advanced software CG animation technology to help you understand.

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.

Fuel injectors are attached to the fuel rail. It is very time consuming to detect and prove a clogged fuel injector. The technician needs to disassemble the fuel rail, de-activate the fuel pump and perform lengthy tests to prove the fault. However, there is another way. Using current ramping techniques the technician is able to prove the fuel injector without any disassembly at all. Get the scoop here and save time.

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
