We covered letters A through C in the first part of the series. Today we are focusing on letters D through F. Enjoy!
OneHotLap says: Here's a good way to measure displacement: pour beer in the cylinders until they start overflowing, then measure the beer amount used net of spilled beer.
Door Panel – The trim panel that covers the inner shell of a door.
OneHotLap says: That's really good to know in case the racers cannot figure out where to find the door panel. Imagine the manufacturer had screwed up and put it on the exterior of the door!
Dryer (AC) – A component of an automotive air conditioning system that is intended to remove water from the refrigerant.
OneHotLap says: Wait, what, A/C in race cars?! Oh, the travesty! And what exactly do you do with this Glossary definition - challenge the legality of other race cars' A/C systems?
Duct/Ducting – A tube or passage for conveying a material, usually air.
OneHotLap says: But can the duct be made out of duct tape?
Engine – The primary power plant of a car, including all physically attached ancillary components necessary for power production.
OneHotLap says: We need to define what an engine is so it won't get confused with a goat during technical inspection?
OneHotLap says: Love it! Imagine you moved your E36's engine to the rear seat to give your car a mid-engine layout. That's the new normal, people! Perfectly legal.
Engine Mount – A passive mechanical coupling used to support the weight of an engine at its attachment points to the structure of a car.
OneHotLap says: It's good to define this too just in case someone cheated by supporting the engine with their transmission mounts.
Exhaust Pipe – A duct of unspecified dimensions, the function of which is to convey exhaust products toward the rear of a car and away from the driver.
OneHotLap says: Another eye-opening definition! And would it still be considered an "exhaust pipe" if it were a side exhaust and thus "conveying exhaust products" toward the side of the car instead of the rear??
OneHotLap says: We've all seen a fan before - is it different for race cars?
OneHotLap says: Ha! Good to straighten that out too. Imagine a club racer showed up for the race with these Fenders instead!
OneHotLap says: Got it! On the right are instructions on how to use it too.
Firing Order – The order in which the cylinders in a reciprocating engine produce power under normal conditions.
OneHotLap says: That's it? I would've expected a trickier name like Zündfolge.
OneHotLap says: Good to know it's not THIS!
Float – A carburetor component which, with an associated valve, controls the fuel level in the reservoir supplying the carburetor jet(s).
OneHotLap says: I always thought a float had something to do with mixed drinks...
Fluid – Any material that readily flows at the specified temperature (for example, liquids and gases at room temperature.)
OneHotLap says: That helps, I'll know a fluid when I see it!
OneHotLap says: Got it!
Going racing is so much more fun than I'd ever expected! Stay tuned for the rest of the Racing Glossary!
