HYPEWHIP on Instagram: "Thoughts? 😮 While American V8s prioritize simplicity with short, robust timing chains located deep within the engine block, German engineering favors a high-precision approach using sprawling, complex chain systems. These lengthy chains are necessary to reach dual overhead camshafts, allowing for the high-RPM performance and advanced variable valve timing that German cars are famous for. However, this sophistication introduces more failure points, as long chains require

Variable Valve Timing Explained: An Appreciation of How Quickly Engines Operate

Here is a quick video of how a PRV works on propane tanks when propane inside of a tank expands and the internal pressure rises. This is video from last nights structure fire. Pressure Relief Valve (PRV) The most critical safety device on a 420-pound propane tank is the pressure relief valve. Its main function is to prevent excessive internal pressure from causing the tank to rupture or explode. During a fire, heat causes the propane inside the tank to expand and the internal pressure to rise. W
