While you may have heard of a drivetrain, you may not be familiar with how it works. The term is often used interchangeably to also refer to powertrain or driveline equipment. A drivetrain includes the transmission, driveshaft, axles, and wheels. With this in mind, the drivetrain works in tandem with the engine to rotate the wheels. As movement is a vehicle’s primary function, the drivetrain system is an essential component to such structures. Read more >>

Screws are a common fastener used for the assembly of parts, typically being used for wood, sheet metal, and plastic. Screws are notable for their helical ridge, allowing them to be self-threading as they are driven into a surface and pull materials together. In order to install a screw, one needs a tool that matches the head of the fastener. Screw heads can come in numerous styles, those being chosen for a functional or decorative purpose. In this blog, we will discuss the primary types of screw heads, allowing you to better understand how such fasteners are used. Read more >>

When discussing bias in relation to diodes and circuitry, one is referring to the establishment of current sets or voltages at various points of an electronic circuit for the means of promoting specific operating conditions for a component. With a standard diode, current may only flow in a single direction, meaning that forward bias will permit flow in a forward direction while reverse bias will impede voltage. With Zener diodes, on the other hand, reverse voltage is impeded until a specific threshold is met, at which point conduction will begin in the reverse direction. To help you better understand the Zener diode and how it differs from standard types, we will discuss its functionality and how it affects the general operations of a circuit. Read more >>

Typically utilized for internal combustion engines, starter motors are an essential mechanism that functions to get an engine up and running. Due to the way energy is created within a combustion engine, engaging any pistons within the power unit requires the use of a starter motor. Generating movement through the use of inertia produced by components allowing the engine to intake air, starter motors can be found in electric, pneumatic, or hydraulic types. In detail, we will go over how a starter motor functions and why they are employed within vehicles. Read more >>

Cylinder heads and their parts are items that function together to form a structurally reliable unit fit for fuel combustion and heat applications. Commonly constructed with a head gasket, intake & exhaust ports, cylinder head valves, combustion chambers, fuel injectors, camshafts, spark plugs, and various smaller components, cylinder head assemblies are what gives an engine life. Within this blog, we will go into detail about the major parts within a cylinder head and how they are constructed to power internal combustion engines. Read more >>
