A two-stroke diesel engine uses compression ignition to convert fuel into motion through two piston strokes per crankshaft revolution:
-
1. CompressionThe piston moves up, compressing the air-fuel mixture in the combustion chamber.
-
2. Power
The fuel ignites, and the piston moves down, expelling exhaust and powering the engine.
Here are some other things to know about two-stroke diesel engines:
-
-
Invention
Hugo Güldner invented the two-stroke diesel engine in 1899.
-
-
Power-to-weight ratio
Two-stroke engines often have a higher power-to-weight ratio than four-stroke engines because they have a power stroke twice as often.
-
Moving parts
Two-stroke engines have fewer moving parts, which makes them easier to maintain and cheaper to manufacture.
-
UseTwo-stroke engines are popular in mopeds and motorcycles in regions with less stringent emissions regulations. They are also used in power tools like chainsaws and leaf blowers.
