Tech Tip: Catalytic Converters Play an Important Role in the Emissions-Compliant Engine
The design and function of catalytic converters has changed dramatically since their introduction in 1975. The first "two-way" catalytic converters were oxidizing-only designs that combined hydrocarbon (HC) and carbon monoxide (CO) with oxygen to form water vapor (H2O) and carbon dioxide (CO2). Oxidizing converters were originally manufactured in pellet bed or monolithic "honeycomb" styles. Currently, the monolithic style has proven to be the most durable.
Mitch Schneider: ‘But, Daddy … I Swear I Wasn’t Speeding’
It must have been quite a sight – me sitting behind the counter staring at the computer screen, looking at the digital images, shaking my head in disbelief. After all, it isn’t every day you see a fairly late-model vehicle with the entire bottom of the undercarriage torn away. But, then again, I knew it was going to be ugly when one of my techs stuck his head in the office door and quietly said, "Hey, boss! You’d better come out here and take a look at this … Oh, yeah, and bring the digital!"

Jaguar Tech Tip: Engine Noise? Don’t Worry About It
Rattling, knocking, thumping and squealing sounds are fine, as long as they’re coming from a haunted English castle. But nobody likes to hear any of those noises coming from under their "bonnet." With more foreign manufacturers building power plants using tighter tolerances, hydraulic valve lash adjusters and serpentine belts, noisy engines are becoming a thing of the past – or are they?
Down the Road: Advances in Engine Technology
Two engine technologies that have been around for years are generating plenty of interest these days as the automakers look to create better fuel efficiency, without sacrificing power — direct injection for gasoline engines and turbocharging. Direct injection for gasoline engines is where fuel is injected right into the combustion chamber of each cylinder, as
Tech Tip: Prescription for RX-7 A/C Repair
One summer afternoon, he dropped the car off for its 60,000-mile service and mentioned the air conditioning had stopped working. Also, air was only blowing out of the defroster ducts. After a "quick" test drive, I brought the car in to check out the problem.

This article is dedicated to some Ford specific issues that, after being brought to light, can save your shop thousands of dollars in wasted time and liability. There may be some other makes out there with some similar designs and quirks, but the only technical references will be for Ford vehicles. By Glen Beanard Giddy
