Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why that is and what it means.

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

Any diesel-engine manufacturer that confidently claims it produces an oil-burner with the “world’s lowest compression ratio,” will no doubt draw the immediate attention of inquisitive enthusiasts, ...

Why Do Diesel Engines Make So Much Torque? If you compare gasoline and diesel models of the same vehicle, the diesel engine ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...
