What causes high fuel consumption in a diesel engine?
There are several causes for high fuel consumption in a diesel engine. These include a difference in the weight of the vehicle, increased usage of air conditioning, and a difference in tire pressure.
How do you calculate lubricating oil consumption for a diesel engine?
The consumption of lubricating oil for a diesel engine depends on the operating conditions and the design of the engine. There are some averages depending on the year of the engine. Pre 1980's engine are around 25% of fuel consumption. Pre 1990 engines are around 20% of fuel consumption and more recently built diesel engines are around 1% of fuel consumption.
How do you calculate fuel consumption in diesel engine?
IT CAN BE CALCULATED THEORETICALLY & PRACTICALLY:- 1. theoretically--- For this you must know the SFC(specific fuel consumption) of the engine at the given load. for example(let us consider a diesel generator of 20 kw having SFC as 232 gm/kw-hr at 75% load) (20x0.75)x232 therefore Fuel consumption in ltrs/hr= =4.094ltr/hr 0.85x1000 here 0.75 is for 75% load 0.85 is density of diesel 1000 is factor to convert milli-litre into litres
Does load affects fuel consumption per hour of a diesel generator?
If the generator is to maintain the same rpm and power output, then a heavier load will increase the diesel consumption. The revolutions per minute the generator runs will increase as the load increases, thereby resulting in an increase in diesel consumption to maintain the high rpm. A Generator has a governor which attempts to maintain frequency at 60 Hz for North America. For the generator to increase the power output at the same frequency…
How does diesel fuel ignite in the engine?
The engine's pistons compress the fuel (an air and diesel oil mixture) in the cylinders and the heat generated by that compression causes the fuel to ignite. A longer answer Diesel engines ignite their fuel solely by means of compression: whilst spark plugs are used to ignite the gasoline fuel and air mixture in gasoline engines, in diesel engines the diesel oil and air mixture is compressed to a very much higher degree, which causes…
What is the major difference between a petrol car and a diesel one?
The primary difference between a petrol car and diesel car is the consumption rate - diesel and petrol are refined from mineral oil using differing methods. The result is diesel engines having a lower fuel consumption rate than their petrol counterparts when installed in a vehicle of similar mass. CO2 emissions are also lower in a diesel engine than they are in a petrol engine.
Can I used unleaded fuel in a diesel van?
If the van has a diesel engine, then you MUST use diesel fuel. Unleaded gasoline will destroy a diesel engine. Diesel fuel is also used as a lubricant in a diesel engine. The use of any other fuel except diesel will result in serious damage. If you have put unleaded in your diesel, do not start or drive this vehicle until you drain the tank and change all the fuel filters.
Why twin spark is used only in petrol engine?
Diesel engines do not use spark plugs to ignite the fuel. Instead they use the actual compression of the piston to ignite the fuel. To start a diesel engine a glow-plug is used, once the engine has started the compression causes the ignition. As a results of this diesel engine blocks are heavier to take the force of the ignition
What causes a diesel to idle?
Diesels run on compressed fuel and air. An injector pump sprays fuel into the cylinder and mixes it with the air. When the piston rises to the top of the cylinder it compresses the fuel / air mixture and causes the mixture to ignite powering the engine. The speed of the engine is controled by the throttle plate which controls the amount of air entering the engine as well as the metering valve on the…
What happens if you put the wrong type of fuel into a 1993 Honda 50?
If your engine is not a diesel engine and you put diesel fuel in it is going to smoke allot and could cause internal problems. Now if your car is a diesel engine and you put regular fuel in it it probably wont run for long, but if you just put a different grade of fuel in you will be just fine. let say your car takes premium fuel (92 octane) and you put 89…
What do you mean by specific fuel consumpion?
Specific fuel consumption is an exact measure of how many pounds (or other measure of weight or volume) is used to produce each horsepower an engine produces. For example, if you have a diesel engine running at a certain speed that produces 10 HP while burning 4.5 lbs of fuel per hour, its specific fuel consumption is .45 lbs/HP.
In a dual fuel engine what is the ratio of producer gas and diesel consumption?
In the Hardstaff OiGi (TM) dual fuel system the diesel fuel can be as low as 25-30% of it's normal value when combined with gas to acheive similar energy outputs. In a diesel engine the fuel represents only 1-2% of the fuel mixture, the rest being air. This is confused slightly in modern engines as post ignition injection occurs to provide a longer burning flame front to increase torque output. So I think your answer…
Can you use diesel fuel in a 2000 Ford Focus?
Do NOT use Diesel fuel in a Ford Focus. The engine will stop running and you will have to drain the gas tank to rid the car of the diesel fuel. Gasoline engines are not designed to run on diesel. They do not have enough compression to cause the diesel fuel to combust The only engine used in a 2000 Ford Focus was the 2.0 which is NOT a diesel engine.
Why does a diesel engine use a different type of fuel?
Diesel engines do not require "ignition" to burn diesel fuel--it is powered by the "heat of compression" therefore diesel fuel has a much higher "flash point" than gasoline. If you were to put gasoline in a diesel engine you would probably blow the heads off the engine. Due to lower "flash point" (temperature when fuel ignites). If you were to put diesel fuel in a gasoline powered engine, it would not ignite and engine will…
What is the working principle of diesel engine?
Diesel engines work much in the same way as any other internal combustion engine. They require the same 4 things to run; fuel, air, ignition, and compression. The main difference is that a diesel engine does not have sparkplugs, which are used in gasoline engines to ignite the fuel. Diesel engines instead use high cylinder compression to press the mixture of fuel and air into as small of an area as possible. This compression causes…
