Working Of A Car Engine

How a Car Engine WorksA gasoline engine operates on the principle of combustion. A fuel/air mixture is pulled into a cylinder, the cylinder is then closed off and the piston is thrust upward to create compression. A spark is introduced to ignite the mixture to create combustion to thrust the piston downward in the engine […]

2 Stroke Diesel Engine

The Two-Stroke CycleLike the four-stroke engine, the two-stroke engine must go through the same four events: intake, compression, power, and exhaust. But a two-stroke engine requires only two strokes of the piston to complete one full cycle. Therefore, it requires only one rotation of the crankshaft to complete a cycle. This means several events must […]

Governers Used in Cars and Different Other Things

Fig 28 simplified Mechanical-Hydraulic Governor Diesel engine speed is controlled solely by the amount of fuel injected into the engine by the injectors.

A wave is defined as the transfer of energy from one point to another. There are two large, all encompassing categories of waves: mechanical and non-mechanical. Mechanical waves require a medium for the transfer of energy to occur. For example, water waves are mechanical. Tsunami waves released after an earthquake transfer the energy of the […]


A wave pulse is a disturbance that moves through a medium. A periodic wave is a periodic disturbance that moves through a medium. The medium itself goes nowhere. The individual atoms and molecules in the medium oscillate about their equilibrium position, but their average position does not change. As they interact with their neighbors, they […]
