High Performance Engines
Jeffrey Bradshaw
Engine Of Intent
* Street Driving – Fuel Milage, Ie every day drive.
* Towing - Torque, Idles from 500 to 4500. Farm truck
* Drag Racing- high horse power, full race
* Street/Strip- Hardest to build, emissions & horse power
* Oval Track- long race, gas milage and horse power
* Pikes Peak Hill Climb- Alltitude changes, a lot of adjustments
* Truck Pulls- High torque, mile per hour

Atmosphere
Atmosheric pressure (PSI) at sea leval is 14.7 containing 78% nitrogen and 21% oxygen and 1% unknown malucules. Horsepower and many other components are effected by atmospheric pressure ( mother nature trying to get into the motor when the valves open).
Pressure Differential: ADiffrence in pressure, positive psi is always going to move toward negative psi to maintain a constant psi of 14.7psi (at sea level).
Volumetric Efficiancy: (V.E.) The engines ability to breath. Knocking (also called knock, detonation, spark knock, pinging or pinking) in spark-ignition internal combustion engines occurs when combustion of the air/fuel mixture in the cylinder starts off correctly in response to ignition by the spark plug, but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front. The fuel-air charge is meant to be ignited by the spark plug only, and at a precise time in the piston's stroke cycle. The peak of the combustion process no longer occurs at the optimum moment for the four-stroke cycle. The shock wave creates the characteristic metallic "pinging" sound, and cylinder pressure increases dramatically. Effects...
