A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the … See more The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-stroke engines, his had a separate … See more Although the principles remain the same, the mechanical details of various two-stroke engines differ depending on the type. The design … See more Direct injection has considerable advantages in two-stroke engines. In carburetted two-strokes, a major problem is a portion of the … See more Crankcase-compression two-stroke engines, such as common small gasoline-powered engines, are lubricated by a petroil mixture in a total-loss system. Oil is mixed in with their … See more Two-stroke gasoline engines are preferred when mechanical simplicity, light weight, and high power-to-weight ratio are design priorities. By mixing oil with fuel, they can operate in any … See more Many modern two-stroke engines employ a power-valve system. The valves are normally in or around the exhaust ports. They work in one of two ways; either they alter the exhaust port by closing off the top part of the port, which alters port timing, such as See more Diesel engines rely solely on the heat of compression for ignition. In the case of Schnuerle-ported and loop-scavenged engines, intake and … See more WebUsing the following information, determine how many degrees the crankshaft will rotate with both the intake and exhaust valves seated.
