Diagnostic Solutions: Exhausting the Possibilities...Performance Upgrades Fresno CA
In general, the exhaust valve opens before the piston reaches bottom dead center to release the exhaust gas pressure remaining at the end of the power stroke. When the exhaust valve opens, a high-velocity pressure wave is created in the exhaust port and exhaust manifold as the high-pressure exhaust gases exit the cylinder.

Depending upon the market to which an import shop might be catering, the term "performance exhaust" can have two different meanings. The first market actively seeks out the throaty rumble and chrome-plated look as part of the street-driving scene. The second market installs an exhaust system that produces the most horsepower for a performance application. Sometimes the two markets are identical and sometimes they're not. THE EXHAUST EVENT
To better explain the difference between appearance and function, let's look at how the intake, compression, power and exhaust strokes really work in a modern Otto cycle engine. The high-speed power output of a naturally aspirated engine depends upon the length or duration in crankshaft degrees of the intake and exhaust valve opening events. In a performance engine, air flow is generally increased by opening the intake and exhaust valves early and closing them later during each combustion cycle. Increasing valve open duration times also increases valve overlap. When the piston reaches top dead center (TDC) as it travels from the exhaust stroke to the intake stroke, the timing events of the intake and exhaust valves will "overlap," leaving both valves slightly open at the same time. Exhaust tuning in a naturally aspirated engine depends largely upon how much valve overlap is present at TDC. The longer the intake and exhaust valves remain off their seats, the greater the valve overlap between the intake and exhaust valves and the grea... |
