How efficient was the Otto engine?
Atmospheric engine The Lenoir engine was an engine that burned fuel without first trying to compress the fuel/mixture. The Otto/Langen atmospheric engine ran at 12% efficiency and produced .
Do diesel engines work on Otto?
This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. Diesel engines are used in aircraft, automobiles, power generation, diesel-electric locomotives, and both surface ships and submarines. in the diagram, below).
What is Otto cycle and diesel cycle?
Otto cycle is used for petrol or spark ignition engine while diesel cycle is used for diesel or compression ignition engine. The main difference between Otto cycle and Diesel cycle is that in Otto cycle heat addition takes place at constant volume and in diesel cycle heat addition takes places at constant pressure.
Who was the first person to build a working four-stroke engine and when was it built?
The four-stroke cycle was patented in 1862 by the French engineer Alphonse Beau de Rochas, but since Otto was the first to build an engine based upon this principle, it is commonly known as the Otto cycle.
Which has higher efficiency Otto or diesel?
Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be operated to higher compression ratio, the engine can actually have higher efficiency than an Otto cycle when both are operated at compression ratios that might be achieved in practice.
How many strokes are there in Otto cycle?
four engine strokes
The Otto Cycle involves four engine strokes. A stroke is defined as a process in which the cylinder’s piston moves up to the top of the engine or down to the bottom of the engine.
Which fuel is used in Otto engine?
The Otto cycle engine uses a spark to ignite a mixture of air and – traditionally – gasoline2 compressed by the piston within the engine cylinder.
Which is better Otto cycle or diesel cycle?
The Otto cycle has less compression ratio (7:1 to 10:1) but in diesel cycle the compression ratio is high (11:1 to 22:1). In Otto cycle as well as in diesel cycle heat rejection takes place at constant volume. The efficiency of Otto cycle is less as compared with the Diesel cycle.
Why is diesel cycle better than Otto cycle?
Where did Nikolaus Otto go to school?
Otto’s Early Days His father died in 1832 and he began school in 1838. After six years of good performance, he moved to the high school in Langenschwalbach until 1848. He did not complete his studies but was cited for good performance.
Who invented Otto engine?
Nicolaus OttoOtto engine / Inventor
