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.
Why is 2 stroke diesel engine rarely used?
There are four main reasons: Two-stroke engines don't last nearly as long as four-stroke engines. … Two-stroke
engines do not use fuel efficiently
, so you would get fewer miles per gallon. Two-stroke engines produce a lot of pollution — so much, in fact, that it is likely that you won't see them around too much longer.
Are all Detroit Diesel engines 2 stroke?
The Detroit Diesel Series 71 is a
two-stroke diesel engine
series, available in both inline and V configurations. … Inline models included one, two, three, four and six cylinders, and the V-types six, eight, 12, 16 and 24 cylinders.
What makes a Detroit Diesel a 2 stroke?
A two-stroke diesel engine is
an internal combustion engine that uses compression ignition, with a two-stroke combustion cycle
. It was invented by Hugo Güldner in 1899. In compression ignition, air is first compressed and heated; fuel is then injected into the cylinder, causing it to self-ignite.
Are diesels 2 stroke or 4 stroke?
Diesel engines are
4-stroke
, but they differ from their gasoline-powered counterparts in their method of combustion. Diesels rely on very high compression ratios to ignite the air/fuel mixture rather than a spark plug.
Can a 2-stroke engine run on diesel?
A two-stroke diesel engine is an internal combustion engine that uses compression ignition, with a two-stroke combustion cycle. … In compression ignition, air is first compressed and heated; fuel is then injected into the cylinder, causing it to self-ignite.
Why are 2-stroke engines banned?
Answer: Two-strokes left the market
because they could not meet steadily-tightening EPA standards for vehicle exhaust emissions
. … A four-stroke engine has a separate piston stroke for each of the four functions necessary to a spark-ignition engine: intake, compression, power, and exhaust.
Why do Detroit Diesels run away?
Diesel engine runaway occurs
when a diesel engine ingests a hydrocarbon vapor, or flammable vapor, through the air intake system and uses it as an external fuel source
. As the engine begins to run off these vapors, the governor will release less diesel fuel until, eventually, the vapors become its only fuel source.
Is a 60 series Detroit a 2 stroke?

Is there a six stroke engine?
The term six-stroke engine has been applied to a number of alternative internal combustion engine designs that attempt to improve on traditional two-stroke and four-stroke engines. … Usually, one cylinder makes two strokes while the other makes four strokes, giving six piston movements per cycle.
How many cylinders does a 2 stroke engine have?
The
three-cylinder
, opposed-piston, two-stroke engine configuration has slightly overlapping gas-exchange events, resulting in a phenomenon known as cross charging.
What are the advantages and disadvantages of a 4 stroke engine?
More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes.
Less pollution
:- As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.
Why are two stroke engines more powerful?
What's the difference between 2-stroke and 4-stroke engines? …
Because combustion takes place with each revolution of the crankshaft with a 2-stroke
, this format puts out more power than a 4-stroke engine and the power has more instantaneous delivery.
What fuel is 2 stroke?
What is 2 stroke fuel? Two stroke fuel is basically
unleaded petrol mixed with 2 stroke oil
. The oil to fuel mix ratio should be specified in your engines instruction manual. The oil in 2 stroke fuel is extremely important in lubricating your engine as two stroke engines do not have an internal oil reservoir.
Can you run a 2 stroke backwards?
A two stroke
can run backwards
because the event timing (intake, exhaust, etc) other than ignition is controlled by the piston, and the piston knows only that it's going up and down, not which direction the crank is turning.
