Why 2-stroke engines are not used in cars?

Originally Answered: Why don’t cars use 2 stroke engines? Two stroke engine is unable to fulfill the current requirements of power, speed, pickup, efficiency and more prominent point is that emissions from its exhaust is too much compared to 4 stroke engines either petrol or diesel.

Is 8 stroke engine possible?

An 8-stroke internal combustion engine 1 according to the present invention can generate power at high efficiency by alternately repeating four strokes due to combustion of the fuel and four strokes due to evaporation and expansion of injected water while re-circulating combustion gas, re-taking and recompressing the …

Is there a 3 stroke dirt bike?

How many degrees of crank rotation for a 3 stroke engine?

In one of my models of a proposed 3 stroke combustion engine, if you think of a twin cylinder 2 stroke design where 1 piston is shared by 2 cylinders, combustion is happening one one side at a time, separated by 540 degrees of crank rotation.

How does a two-stroke engine work?

It uses intake and exhaust ports along the cylinder wall to manage intake and exhaust gases, creating an organic exchange of pressures and vacuums without the use of valves, fuel injection, or even an accelerator pump. And where a four-stroke might use turbocharging or supercharging to increase power, a two-stroke uses sound.

Why are two-stroke engines bad for the environment?

The fact that you could watch the pollutants exiting the tailpipe of a two-stroke vehicle didn’t sit well with the burgeoning environmental movement, and the idea of smoke visibly exiting the exhaust was thought to be directly tied to decades of thick smog in cities like Los Angeles.
