What supplies fresh air to the air box in a two stroke diesel engine?

• A. Turbocharger
• B. Blower
• C. Piston
• D. Compressor

Answer: (B)

In a two-stroke diesel, fresh air must be forced into the scavenging system to push out exhaust and fill the cylinder for the next cycle. A blower is the device designed to do just that—pushing a controlled volume of air into the air box to provide reliable scavenging air for every engine revolution. A turbocharger uses exhaust energy to compress intake air and can lag at low speeds, which isn’t ideal for the immediate air supply the air box needs. Piston isn’t used to push air into the air box, and while a compressor can perform similar work, the standard source described for this setup is the blower.
