This article serves as a basic introduction to what is possible with hydraulics for your garden tractor. There are a wide variety of pumps, valves, motors, hoses, etc. I hope this article inspires you to research more of what you can do with the physics of fluid.
When something is wired “in parallel” it means it is wired alongside a circuit with its own positive wire. Now that we have a basic idea of electrical theory, let’s examine how it is all wired together. The example below illustrates wiring for an engine that uses battery ignition and a stator charging system.
The ignition circuit consists of your battery, ignition switch, ignition coil, breaker points, condenser, and spark plug. When your ignition switch is turned in the “start” and “run” position, the “I” or ignition terminal is energized and power flows from the battery through the primary winding of the ignition coil through the points and back to the engine ground. The primary winding of the ignition coil are the two small terminals marked + (positive) and – (negative). A small gauge wire goes from the ignition switch and connects to the + positive terminal of the ignition coil. The breaker points and condenser are both connected to the – (negative) terminal of the ignition coil. Your spark plug cable is connected to the secondary terminal which is the large wire port in the top of the ignition coil. Your spark plug is then connected to the high tension spark plug cable and screwed into your engine’s combustion chamber.
The purpose of an internal combustion engine is to transform chemical energy into mechanical energy. This is accomplished by igniting an air/fuel mixture that causes a shaft to rotate. We then use this rotating shaft to create useful work.
