If you have an internal combustion engine that actually runs, then your camshafts are spinning twice as fast as your crankshaft. Change the rate at which either of the two spins in relation to one ...

A urethane timing belt moves samples into position in this CAD simulation of an automated blood sampling machine. Timing-belt drives transmit torque and motion from a driving to a driven pulley or ...

If a timing belt breaks, one of two things are likely. Either the broken belt will allow the valves and pistons of the engine to collide, instantly turning the engine to scrap. (This is what happens ...

Q: I have a 2006 Kia Optima with 64,000 miles and it sits outside 24/7. When it's wet, the car makes a screechy noise in the morning as I leave for work. It lessens as I accelerate, but when I start ...

Frictional belt drives reliably transmit power from source to load without asking much in the way of upkeep. Their modest needs stem from the fact that Frictional belt drives reliably transmit power ...

Your car's internal combustion engine requires a massive amount of individual parts to make it run. From the tiniest nuts and bolts to hulking crankshafts and engine blocks, modern motors are composed ...
