What is thermal efficiency of petrol engine?
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
What is the combustion efficiency in an automobile engine?
It varies somewhat depending on engine design, but a gasoline engine is approximately 30% efficient due to heat, mechanical loss, etc. Despite modern engines getting about 98-99% efficiency out of the gasoline.
How do you calculate the efficiency of a machine?
Efficiency is nothing but calculating how the machine is performing for what it has been made for, Efficiency is usually calculated in % as (output/input )X100. for Eg. the Thermal efficiency of an reciprocating gasoline engine can be calculated as follows, Let, the input for an reciprocating engine is 12MJ and its out put is 4MJ then Efficiency is (4/12)X100 = 33%
Who is better gasoline engine or diesel engine?
diesel. Diesel engines tend to have better efficiency especially at less than full load. Gasoline/Petrol and LPG engines tend to have better power weight ratios.
Why efficiency of heat engine is more in winter as compare to summer?
Because a thermal engine efficiency is directly linked to the difference of the temperature of the gases involved .As the gasoline burns at a set temperature , the lower winter temp helps to widen the temp differential between the ignited gasoline and exaust. Unfortunatley the colder air is more dense and generate more drag than in summer , more than negating the increased engine efficiency. To put it in rough numbers , you may get 0.5% more engine efficiency but you lose some 4% more to extra drag.
Internal combustion engine of a gasoline engine?
a gasoline engine is an Internal combustion engine
What happens when your oxygen sensor is not working?
If your oxygen sensor stops working the fuel (gasoline) and air mixture will be incorrect. Usually this means your fuel efficiency will decrease -- that is, the engine will burn more gasoline than necessary. It's possible however, if it begins to run too lean (not enough gasoline for the amount of air) it can damage the engine. But, this is unlikely.
What came first petrol engine or diesel engine?
The gasoline engine came first. The gasoline engine was invented and patented in 1823 with the first efficient gasoline engine developed in 1876. The diesel was invented in 1893 which was 70 years after the gasoline engine.
Why diesel engine has volumetric efficiency greater than gasoline engine?
In diesel engine the air is only compressed in compression stroke and then diesel is entered .......so only small amount of fuel is consumed then petrol engine which take lot amount of fuel.......
How do you calculate the efficiency of a 100 cc gasoline engine with compression ratio 8-1 i want details with formulas if possible?
so u do 45+1=67
What will happen if premium gasoline is put into a diesel engine?
If you're asking what will happen if you put gasoline in a diesel engine, the engine will be destroyed if you run it on gasoline.
What are the differences of internal combustion and gasoline engine?
and internal combustion engine and a gasoline engine are the same thing.
