Vehicle Performance

Vehicle performance is the study of the motion of a vehicle. The motion of any vehicle depends upon all the…

How to Determine Gear Ratio

In mechanical engineering, a gear ratio is a direct measure of the ratio of the rotational speeds of two or…

Classical Design of Gear Train

In order to find the required overall gear ratio, the compound gear train contains two pairs of gears, d-a and b-f (Figure 1). The…

Gear Ratios

Gear ratios are a core science behind almost every machine in the modern era. They can maximize power and efficiency…

Piston motion equations

The motion of a non-offset piston connected to a crank through a connecting rod (as would be found in internal combustion engines), can be expressed through several mathematical…

OVERSQUARE VS UNDERSQUARE

A closely related topic to rod ratio is that of bore and stroke. If the bore and stroke dimensions in…

BEST ROD RATIO?

Essentially, there is no “best” rod ratio for any given engine. Some say to use the longest rods that will…

What is Bore-Stroke Ratio?

Bore-Stroke Ratio is the ratio between the dimensions of the engine cylinder bore diameter to its piston stroke-length. The cylinder…

How Engine Capacity affects its performance

The engine’s capacity plays an important role in determining various engine outputs such as engine power, torque, and mileage. It is the volume,…

What is Engine Capacity (cc)

The term “cc” stands for Cubic Centimeters or simply cm³ which is a metric unit to measure the Engine’s Capacity or its…

What is the Mean Effective Pressure (MEP) of an engine ?

The Mean Effective Pressure (MEP) is a theoretical parameter used to measure the performance of an internal combustion engine (ICE). Even if it…
