Historically, an engine is technically any machine that converts energy into force, such as a catapult, according to Reference.com.
A:A muffler reduces the exhaust noise of a vehicle by blocking and reflecting sound waves. Inside the muffler is a series of baffled chambers and perforated barriers that break up the high-velocity sound waves as they flow through the device, reducing the overall noise level.
A:A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system, speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.
