  WHAT IS A SPARK PLUG? HOW DO SPARK PLUG WORKS? Spark Plug Definition - A spark plug is an electrical device that is used in internal combustion engines to ignites compressed aerosol gasoline using an electric spark. The electrical component is highly used to perform mechanical jobs. In simple term , spark plugs turn an energy source (gasoline) into movement. For instance, we have petrol which is highly flammable and also air, that could cause an explosion when mixed. The plug is like lighting fire to the compressed gas. Spark plugs are either regular (replacement) or performance. The performance spark plugs are tougher, having the ability to withstand a greater change in temperatures and mechanical stresses. However, regular types can’t. well, we’ll further look into them below this article. Functions of Spark Plugs - A spark plug has two major functions in internal combustion engines which include - Igniting fuel/air mixture - as electrical energy is transmitted throug...

  WHAT IS AN AXLE? An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type axle is referred to as a spindle. Types Of Axle - Axles come in three standard types - Rear axle - This axle is responsible for the power supply to the drive wheels. It comes in two halves, called half-waves, which are connected by the differential. In most cases, the rear axles are under tension, meaning that they rotate with the vehicle’s wheels. Front axle - This axle is located in the front of the vehicle and is responsible for assisting in steering and pro...

  WHAT IS HYDRAULIC PUMPS? HOW IT WORKS? A hydraulic pump converts the mechanical energy from the prime mover into hydraulic energy for use by the system. Hydraulic energy is the combination of pressure and flow required by the actuators to perform useful work. It is important to understand that hydraulic energy is both pressure and flow combined, because one without the other cannot achieve work. Pressure would just consist of trapped fluid and flow would have no energy to move fluid alone. A hydraulic pump pushes on fluid, and in this regard, fluid can be considered a solid as it is transmitted throughout the machine and then pushes on actuators to eventually move loads. Motion control professionals will have me point out that oil is compressible, but that’s a discussion for another blog. The point is that a pump could be pushing on sand, ball bearings or any other solid medium capable of taking the shape of its container, and the result would still be the transmission of force...
