Tech Feature: Exhaust Leaks and the Stoichiometric Ratio

When I was a kid, I used to watch my dad, who started out as a diesel mechanic, tune up cars and trucks from time to time. He would turn the adjustment screws on the carburetor until the engine smoothed out and started to purr. Then, after listening closely to the rumbling of the motor, the adjustment screws would get one final tweak. He would always bend down and cup his hand around the belching tail pipe exhaust and take a big sniff of the fumes, and then go back to his adjustments. That was back in the 60s and 70s before PCMs, O2 sensors and catalytic converters.

Tech Tip: Wave Dynamics for Headers and Pipes

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.

Tech Feature: Servicing Diesels in Your Shop

Is there a diesel in your service bay? Maybe not now, but there definitely will be in your future. You’re going to see trucks as well as SUVs and passenger cars. Mercedes-Benz produced a 3.0L V6 diesel-powered SUV for the 2008 model year and Volkswagen has a Twinturbo 5.0L V10 diesel engine in its Touareg. As the automakers focus on better fuel economy, you might say the diesels are coming again.
