How To Build V-Twin Engine Gasoline Engine

FG-VT9 V-Twin Engine 2 Cylinder 4-Stroke Air-Cooled Gasoline Engine

More than a century ago, in December 2020, I discovered a Harley-Davidson Panhead engine on the engine forum. The engine has a cylinder diameter of 16.7 mm and a stroke of 21 mm.

This engine really caught my attention when I first saw it, so I made my own miniature V2 engine model based on it. I collect a lot of engines because I like them. While they're working, I genuinely enjoy them. State. In an attempt to recover the look and maintain the simulation level as much as possible—including engine noise—I looked up a lot of material on Google and YouTube. However, because the machine is too ancient, I didn't have an actual engine or even look at it. It can be challenging to acquire, and there are only a few collectors who possess it.

I began developing the strategy in January 2020. This is challenging. I can only use the current data to obtain engine information. Instead of using the Panhead engine's rocker arm design, I went with one that has a similar Ohv structure. Yes, it is simple to process, and I am eager to see how it will shorten my production cycle.

All of the engines will be manufactured using CNC. It is ambient and lovely. Since I enjoy collecting it, I will be unable to tolerate it in the future since oxidation will cause it to turn dark. To keep it bright, I'll use an anodized cylinder surface. The rocker cover will be chrome-plated at the same time, and its gleaming appearance will lift my spirits.

I spent a lot of time because I could only finish my production in my own time due to my profession as an engineer. Seven months later, it was finished. I attempted to start, but it was unsuccessful. After that, I began to inspect the camshaft and discovered that the angle was incorrect. Because of my prior expertise in designing engines, I assumed the camshaft angles of the two cylinders were equal. My guess is to battle for, and it also needs to add the angle of the ejector rod tilt, according to my simulation of the 3D plan.

I was going to get one of the cylinders to start. To avoid adding resistance to the cylinder that was ready to start, I took out the spark plug from the cylinder with the incorrect cam. I tested a Hall igniter that I had welded. He was successful. The sound of the engine is fascinating and lovely.

I asked my excellent friend to construct a new cam after I restored the old one, and he did, in fact, use a cutting machine.

I discovered that if the trigger magnet is positioned on the crankshaft's flywheel, he will require two igniters and two Hall triggers, which is not acceptable, etc. when I started assembling the new cam and verified the ignition time of the two cylinders. I will add him to the distributor that is already complete because I began to successfully.

Amazing! It began. This is a fantastic V2 engine that is part of my treasure collection. I am delighted to share the construction design with you, and I will optimize it until it is nearly flawless. You may miss the story that has been told for over a century when you see this engine.
