the explosions which are caused by the throttle being pushed down and the harder you push down the throttle the bigger the explosion ANSWER for single piston , power stroke force the piston to bdc . but during any other stroke , the inertia of the spinning crankshaft force the piston to tdc n bdc
2 stroke engines use oil mixed with the fuel for lubrication. This causes them to pollute the atmosphere. They are also very noisy.
Because is giving you higher torch on a very short time, comparing with 4 stroke.
combustion and expansion
-Low maintainence(no crank case oil to change or valves to set) -Simple in design (VERY easy to rebuild) -The ability to rev much higher than a 4-stroke(less minor shifting) -Impressive "snap" during the power band -Much less moving parts than a 4-stroke A 2-stroke engine fires on every complete engine cycle giving it, in theory, twice the power of a 4-stroke. Unfortunately, due to the engine design restrictions, the 2-stroke's power only becomes available at higher RPMs. At low RPMs 2-stroke engines are clunky and gutless. So, if you ride aggressive, your always on the throttle, you need that quick pick up often, you will benifit from it.
Explain the advantages of four-stroke engine over two-stroke engine
two stroke
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
180 degree. giving it a theoretical twice the rpm of a 4 stroke parallel twin
A four-stroke engine runs cooler than a two-stroke engine primarily because it has a more efficient cooling system due to its longer cycle, which allows for more complete combustion and better heat dissipation. In a four-stroke engine, the intake, compression, power, and exhaust strokes are separated, giving more time for heat to escape during the exhaust stroke. In contrast, a two-stroke engine fires once every revolution, leading to less time for heat to dissipate and often resulting in higher operating temperatures. Additionally, two-stroke engines typically mix oil with fuel for lubrication, which can also contribute to increased heat generation.
Detroit diesel engine is an example of two stroke engine
