#Engine

Here’s a question that may well be impossible to answer, due to the numerous gray areas involved. Sure, we could set all kinds of limitations (e.g., “production run” applies only to engines built by the original manufacturer) and of course you stumble into the quagmire of defining when changes to an engine design become significant enough to result in a different engine… but why should we do that?

Some folks will tell you that you need a big ol’ truck to haul a grimy cast-iron V8, but those folks are wrong! My beater ’92 Civic, which stood up well when compared to the Audi R8, not only sports a trailer hitch (no doubt suitable for hauling popcorn carts weighing up to several hundred pounds) but the cargo-area capacity to take a disassembled Chrysler LA engine.

It’s hard to believe that The General was once so dominant that it sweated over the fear of being split up by the federal government via antitrust regulations, and that GM’s divisions cranked out more than 25 separate passenger-car engine types (counting Opel and Holden models) during the decade. Why, The General boasted ten different car V8s during the 1960s (not counting earlier models intended for warranty replacements, industrial use, etc); eight of those engines were being built in 1965 alone. Imagine a manufacturer today so mighty that it could offer eight totally different V8 engines (in 14 displacements) for sale in its new cars!

Via Top Gear comes this in-car footage of the Porsche GT3 R Hybrid lapping a racetrack and making some peculiar sounds in the process. Part Porsche purr, part RC Car whine, this new note is one of the first hints at what future supercars will sound like, in particular the forthcoming Porsche 918 Spyder. It may not be the most viscerally evocative sound ever recorded, but dammit, it’s the future.

Remember the miracle carburetor that would have halved the gasoline consumption, if the wicked oil companies would not have bought the patent and locked it away? As a matter of fact, the lowly ICE has made great strides when it comes to reducing consumption, a drive that has traditionally been championed in Europe and to some degree Japan.

I have a 2000 Ford Ranger, 2wd 3.0L V6 with 143k miles. The CEL has been on for at least last 70k and I finally went to AutoZone and got the code read. Turns out the O2 sensor is bad and the EGR valve is stuck. Is that the kind of thing that I can fix myself? I don’t want to put a whole lot of money in this truck seeing as it has a lot of miles and has been running reasonably well, if inefficiently (21 mpg all highway), for so long. I have an ok tool set and I do my brakes, but I recently paid $70 to have the fuel filter replaced-I’ve done it before and I didn’t want to do it again. The truck is going back to my parents to be semi-retired and put into “farm use” so I wouldn’t mind fixing it up a little before giving it back but I don’t want to spend a lot.
