What is the efficiency of a gasoline engine?
Gasoline engines have a 30% efficiency, as compared to a Diesel engine having 40% efficiency. COOL HUH
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%
What is the compression psi on a 1990 engine?
Normal compression on a gasoline engine is about 125 psi.
Why gasoline is not used in diesel engines?
Gasoline does not combust properly, or at all, in a compression ignition engine. Gasoline is designed to be ignited by a spark.
What are the differences between otto cycle and diesel cycle?
Mister Rudolph Diesel was aware of the gasoline engine ([http://en.wikipedia.org/wiki/Otto_cycle Otto cycle]) problems and wanted to improve it. The gasoline engine inherently has problems with efficiency and/or fuel. In order to improve the efficiency one must increase the compression ratio of an internal-combustion engine (see the bonus section at bottom of this article). However, in the gasoline engine there is a limit - the gasoline-air mixture will self ignite once the compression gets too high (because every compression drives temperature increase). So, either you can have a low-efficient, low-compression engine that uses a cheap fuel, or you can have a high-efficient, high-compression engine that uses expensive, high-refined fuel that wont self-ignite even at high compression levels (a 120 octane gasoline?). In [http://en.wikipedia.org/wiki/Diesel_engine diesel engine] this problem is solved. The diesel engine can use much higher compression levels than the gasoline engine reaching higher efficiency. In addition, the diesel engine can use fuel that is not nearly as refined as the high-octane gasoline fuel (thus cheaper). To make this possible, Rudolph changed the Otto cycle and created the diesel cycle. The difference is that during compression phase, no fuel is present in the cylinder and thus no self-ignition can happen. The fuel is only injected at the moment the ignition is wanted - when injected into the hot pressurized air the diesel fuel self-ignites immediately (the diesel-air mixture, as we said already, is happy to ignite even at relatively low temperatures).
What happens when diesel fuel is placed in a gasoline tractor engine?
It won't run, that's for sure. Diesel is ignited by compression pressure, not by spark. And the compression in a gasoline engine is not sufficient to ignite the diesel.
How does gas get in the oil?
Bad compression rings can allow gasoline to get into the oil.
Compression ration in diesel engine is?
Higher than a gasoline engine.
What octane gasoline must be used in an engine with 10.5 compression ratio?
91 +
How do you crack metastock formulas?
flush gasoline, and burns
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.......
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%.
