Mechanical engineers design, build, and test mechanical devices such as tools, engines, and machines. Considered the broadest engineering discipline, mechanical engineers work in engineering services, research facilities, manufacturing industries, and the federal government. A mechanical engineer should have particular hard skills, including a solid understanding of industry standards and excellent computer skills, because much time is…

Friction isn’t something we think about too often, but it is one of the more powerful physical forces out there. Friction helped to wear your engine if you don’t keep it in check. Not only does it contribute to erosion and wear,  but it also creates heat, which can definitely hurt your engine, especially over time….

A Centrifugal pump is a mechanical machine that pumps the fluids by converting the mechanical power (rotational energy)  into the pressure energy of the fluid flow. This mechanical power generally supplies by the electric motor or engine. A centrifugal pump uses a centrifugal force to pump the fluids. Therefore, it is known as a centrifugal pump. It is a simplest type of hydraulic…

Air-Fuel Mixture is the combination of the air and fuel (the fuel will be petrol in maximum cases) in a specific ratio that will help the engine to work properly. Every petrol engine will suck the air-fuel mixture for its suction process and the mixture will burn (or combust) using the sparks which result in the combustion process. Types Of Air-Fuel Mixtures: Engines will not work under the…

Normally to shift gears you’d roll off the throttle slightly and pull in the clutch, because the transmission needs to be unloaded for the cogs in the gearbox to slide into the next position. With a quickshifter, that momentary unloading of the transmission is achieved by manipulating the ignition spark. Here’s how it works: There’s a…

History of the Automatic Transmission General Motors and REO both released semi-automatic vehicle transmissions in 1934. These models posed fewer challenges than the traditional manual transmission but still required the use of a clutch to change gears. The GM transmission was the first of its kind to use a hydraulically controlled planetary gearbox, allowing the gears…

A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel. The National Emissions Standards Act, an amendment made in 1965 to the Clean Air Act, set the first federal vehicle emissions standards. Each state has regulations that…

A company from Edinburgh Scotland is building the worlds first hydraulic drone to address the shortcomings of conventional drones such as range and payload weight capacity. The unmanned aerial vehicle (UAV) was inspired by the U.K.S Royal National Lifeboat Institutions (RNLI) building a companion drone for offshore lifeboats challenge. At the moment flowcopter is the only UAV…

The combustion engine is, hands down, one of the most important inventions of all time. But, it comes with a very high cost to the environment – hazardous emissions.  While many leaps in efficiency and emission control have been made over the decades, we can never fully eliminate the release of emissions like carbon dioxide…
