Works way better in fullscreen mode! This is a simulation of how a single piston Diesel engine with a turbocharger works. -You can look inside and see the comments on how i made it. -Move the RPM slider to slow down or speed up engine. - Switch between Illustration and Realistic Model. - In realistic mode, Adjust the fuel bar and hold the electric start button to start the engine. If the engine doesn't start, add mode fuel in it. -- Explanation made by me -- The Intake of the engine is used to push oxygen into the engine chamber, as the piston moves downwards, it creates a negative pressure in the chamber, forcing air into it. Engines compress fuel and oxygen with the help of the piston moving upwards again, then a spark (or in this case just heat) ignites the mixture which in turn, the expanding gasses pushes the piston backwards creating a rotating motion in the crankshaft. Once this motion is complete the gases are useless and they are recycled into the turbo. As the piston continues to move upwards pushing the burnt gasses out into the turbo, rotating the turbo blades, causing the other end of the turbo actually sucking in oxygen to push into the intake for the cycle to continue! Check similar type of projects in the Car Anatomy Studio! https://scratch.mit.edu/studios/1168654/ Updates: -Added more part names. -Added starter pulley. -Fixed timing again. -Added 2 modes (illustrate and realistic) -Added rpm gauge for the realistic mode. (previous updates) -Updated the sound effects a bit. -Added a second valve and corrected the timing. -Added the ability to see what most parts are. -Reduced the minimum rpm to 20. -Added xray variable tags (ignore this) #engine #diesel #simulation #joints
