[MOC] Car TSI Engine
camellia posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello, my friends! Today, I show my MOC model: a car Twins-charge fuel Stratified Injection Internal Combustion Engine whose abbreviation is TSI Engine. Please give me your precious ideas and comments. 1. This MOC model almost includes every component of a real car engine: Cylinder Crankshaft Camshaft Timing belt Twinscharge fuel Stratified Injection Distributor fuel Injection System Distributor Spark Plugs System HALL circuit Lubrication Cooling Generator 2. Besides using LEGO bricks and parts, I add a special electronic component. It is HALL circuit. It uses a HALL chip to simulate Distributor Spark Plugs System. 3. Just as the principle of a generator and the principle of a motor are reverse, I use a motor to drive this engine to simulate the process of a running engine. And each component is running as a real-time sequence. When running, it looks like a real engine more. 4. I hope when you touch this model, you will get more learning of a car engine. I also post a video of learning car engine in Youtube and my website. Now let us view this product. Just enjoy it. Fig. 1 This engine has 4 Vertical Cylinders. Fig. 2 Crankshaft with 4 Pistons, each delays 90 or 180 degrees. Fig. 3 Suction and Exhaust Camshafts with Oblong Lobes to lift Poppet Valves. Fig. 4 Timing Belt. The Medium Blue one is Cooling Water Pump which is driven by Timing Belt. The bottom gear is driven by the crankshaft. The top right gear drives the Suction Camshaft while the top left gear drives the Exhaust Camshaft. The middle left gear is used to adjust the tension of the Timing Belt. Fig. 5 Light blue pipes are Fresh Air Suction: the bottom is Mechanic Charger and the top is Turbine Charger. Fig. 6 Gray pipes are Exhaust pipes: the Exhaust Gas drives the Turbine. Fig. 7 Turbine Fig. 8 Distributor Fuel Injection System Fig. 9 Distributor Spark Plugs System: 4 diode simulate Spark Plugs. Fig. 10 HALL chip Fig. 11 A Magnet is mounted on the Flywheel to active HALL Effect Sensor to detect the position of each piston. Fig. 12 The principle of HALL Effect Sensor. Fig. 13 Lubricate Oil Pump is driven by Crankshaft with Gears. Fig. 14 Perspective View Fig. 15 HALL Effect Sensor (DIY) which is mounted at the end of the Crankshaft to detect the position of each Piston. Fig. 16 Assembled Model Connecting to batteries, this Engine model can operate, just watch the video in I also make a learning video to talk about car engine. I hope my work will bring happiness and learning to you. Please kindly visit http://www.camellia.xin
