A car’s internal combustion engine uses air and fuel for accurate working. The air-fuel ratio required is optimal for continuous combustion and good engine working. In older vehicles, carburetors controlled the air and fuel mixture. After that, the engine control unit used in new vehicles comes with Mass Air Flow (MAF) sensors for measuring airflow.…
The SPST switch, also called a single-pole through switch, comes with one input and one output terminal. Its main function is to make connections and disconnections between input and output. An SPST switch has features to control a single circuit by making or breaking a connection. So it is a simple switch that is employed…
The catalytic converter is a main component of a vehicle that has been used for more than fifty years, and its main function is to reduce emissions generated in a car or vehicle. A catalytic converter, also called a “cat,” is the second part of the vehicle’s system. Other components of the vehicle system include…
An inclined plane is a type of simple machine that has a sloping surface. It is stationary and lacks moving parts. Inclined planes help raise heavy objects easily by applying force against gravity. Inclined planes are important in our daily lives and play a role. In this post, we will cover daily life examples of…
Struts of a car are the main part of the suspension system of vehicles, whose function is to make a connection between the tire or wheel and the body of the car. It exists on the chassis at the front side of front-wheel-drive automobiles. But they do not only exist on front-wheel-drive vehicles since their…
Why Curiosity Matters More Than Ever Every major invention begins with one question: What if? That simple spark—curiosity—has driven centuries of progress. From steam engine to spaceflight, that is one trait all engineers share. Curiosity is not only daydreaming, but it is also an engine for discovery. It urges engineers to find faults that others…
The AG10 button battery is a small non-rechargeable battery. It is a primary cell that comes with alkaline chemistry. It’s working based on the chemical reaction occurring between two electrodes, zinc and manganese dioxide. This battery is part of small handheld devices such as watches, cameras, and calculators. In this post, we cover details for AG10 battery…
Injection and casting molding are two manufacturing processes that help make different products and manufacturing processes. Polyurethane is used for making objects like vehicle gaskets, casters, settings, medical carts, and some other parts. In this post, we will cover the detailed features of injection molding, casting, and urethane casting to find their differences. So let’s…
A framed stencil is a solder paste stencil that is used for the SMT assembly process and comes with laser-cut stainless steel foil configured on an aluminum or steel frame. A framed stencil is an important type of stencil that is used on boards; it provides consistent alignment and accurate solder paste application and is…
With the advancement of technology and equipment, small and thin form factors are being introduced in electronic tools, so small surface mount technologies are now becoming a common part of PCB boards. PCB boards come with fine pitch, larger SMT components, and medium-sized components. For making these boards, a step stencil is preferred. Here we…
