How does a 2 stroke engine work simple?
Overall, a two-stroke engine contains two processes: Compression stroke: The inlet port opens, the air-fuel mixture enters the chamber and the piston moves upwards compressing this mixture. Power stroke: The heated gas exerts high pressure on the piston, the piston moves downward (expansion), waste heat is exhausted.
Does Detroit Diesel still make two stroke engines?
In 1998, MTU, which had purchased Detroit Diesel from Penske in 2006, finally ceased production of all two-stroke Detroit Diesels. (The company continues to manufacture the four-cycle Series 60 Detroit Diesel.) Today, there are still thousands of these engines powering boats of all types all over the world.
How many valves does a 2-stroke diesel have?

How does a diesel engine works?
Diesel vehicles are similar to gasoline vehicles because they both use internal combustion engines. In a compression-ignited system, the diesel fuel is injected into the combustion chamber of the engine and ignited by the high temperatures achieved when the gas is compressed by the engine piston.
Why is a Detroit Diesel called a Jimmy?
Way back in 1938, when it was still known as the GM Diesel Division, Detroit Diesel developed the 2-cycle 71-series engine, named for its per-cylinder displacement. Known as “Screamin’ Jimmys” (here’s why) these engines were always happiest running wide open.
Should I let my diesel warm up?
Let your engine warm up like you warm up in the morning. Let the glow plugs and intake heater do their job. The other thing that’ll keep your engine running longer is preheated coolant. The more cold-starts your diesel is subjected to, the shorter its lifespan will be.
How does a 2 stroke diesel engine work?
How Does a 2-Stroke Diesel Engine Work 1 Intake & Exhaust stroke. 2 When the Piston travels down the exhaust port gets and covered by the Piston. 3 When the Piston Travels a little more down in the inland port also get and covered by the Piston from where, the fresh air finds its way in the cylinder. 4 Compression stroke
Why not a two stroke Detroit Diesel?
The two stroke is just too hard to bring into compliance with modern emission regulations. I am happy to have met James Jensen, a serious enthusiast of Detroit Diesels, who has compiled a short history of the Detroit Diesel engine, with a particular British Columbia flavour; I hope you enjoy.
How does a Detroit Diesel work?
The Detroit diesel worked like this. There was a circle of ports all the way around the bottom of the cylinder. The ports were uncovered near bottom dead center and the blower blew a very strong draft through this area, clean air in one side and clean air and exhaust out the other.
How many intake valves does a Detroit 2 stroke have?
There are no intake valves on a two stroke Detroit you look on top of the head and see 3 rockers. The centre one actuates the fuel injector and the other 2 actuate 4 exhaust valves. So now that you know the parts, I will explain the cycle.
