Biodiesel can extend the life of your engine whether it is in your diesel equipped auto, truck, tractor, bus or highway rig. Biodiesel can increase the longevity of your engine by up to 100 %. Costs are reduced ? whether it be for maintenance or vehicle replacement. The engine last longer , breaks down less frequently resulting in longer vehicle life spans , greater reliability and overall less vehicle costs ? again be it diesel equipped auto , car, truck ,tractor or highway rig.
How can this be so? The improved lubrication properties of biodiesel over regular vehicle diesel fuel results in increased parts longevity by up to 100 %. As a result commercial vehicles may be used for decades as well as travel millions of miles. Increased engine longevity translates into reduced maintenance costs, longer life spans and overall increases in reliability.
Biodiesel is a renewable fuel derived from vegetable oils, animal fats and cooking oils that are processed so that it can be added to diesel fuel as an additive. You cannot just mash up these fats and mix them with your diesel fuel. It is not as if any old Alvero character can make biodiesel in his garage at home. If the biodiesel is not prepared properly in a qualified industrial process ? the contaminants of water, glycerols and other trace elements can well clog up your fuel injectors or even an expensive injection pump. Properly done biodiesel is a safe and beneficial fuel additive ? now being routinely recommended and touted by major vehicle and diesel engine manufacturers.
Prepared properly in a commercial setting. and bought commercially you can be assured that not only will the biodiesel will be safe for your engine to use ? but will even give the benefits of much greater engine life , enhanced reliability and lower maintenance costs overall.
Biodiesel is added to the regular diesel fuel. The percentage added depends on the climate the vehicles or autos will be used in. In warmer climates ? such as tropical or Florida type climates ? a percentage mixture of up to 20 % can be used. A 20 % biodiesel percentage in a truck driven up North to Edmonton Canada in the cold of winter will thicken up in the cold Alberta winter weather.
In such a cold winter temperature a biodiesel mixture ratio of 5 % would probably be used. To increase the blends of biodiesel used commercial vehicles such as trucks and busses can have fuel heaters installed ? either inline fuel heaters of fuel tank heaters.
Why go to all this trouble for biodiesel ? First of all biodiesel is a renewable resource ? crops such as soybean oil or canola can be used instead of scarcer and more expensive petroleum oil based products. Using biodiesel doe mean that we use less regular diesel, however the percentages of biodiesel use are relatively small. For example most diesel manufacturers recommend only 5 biodiesel (B5 mixed wit 95 % regular diesel. Of course again in colder climates such as Edmonton Alberta the percentages may be eve less. Biodiesel is also good for reducing emissions and pollution levels of sulphur, carbon monoxide as well as overall tailpipe smog pollutants.
However as with most good things in life there are disadvantages to the use of biodiesel as a vehicle fuel additive. First biodiesel has slightly less energy than regular diesel fuel, so that the larger the percentage content of the Biodisel in the fuel ? the less power the engine will have to deliver. Fortunately at the low percentages of biodiesel being used as a fuel additive this is not a major issue.
In addition biodiesel spoils with time. If the biodiesel is too be stored for a long period of time ? then additional additives must be added.
As a result of its benefits to reducing petroleum oil use and increasing engine life and reliability biodiesel has a bright and emerging future in our transportation and automotive industries.
The use of biodiesel ? an alternative renewable fuel, is fast on its way up.
The First Diesel Engine
Diesel engines can be broadly distinguished as two-stroke and four-stroke. Bulky engines usually operate on the two-stroke cycle. Lighter engines generally operate on four-stroke cycle.
Generally cylinders are used in multiples of 2, 4, 6, or 8, .It doesn't matter what number of cylinders are being used as long as the load on the crankshaft is counterbalanced to prevent excessive vibration. The inline-6 cylinder is used widely in medium and heavy duty engines.
How these engine work? The temperature of gas rises when it is compressed. When the inlet valve opens air is sucked into the cylinder of a Diesel Enginesdue to vacuum created. The piston then moves upward and compresses air raising its pressure and temperature. As the piston moves up towards the end of compression stroke, injection of diesel fuel the combustion chamber that is cylinder takes place. There is high pressure inside cylinder so the fuel is injected through an atomizing nozzle at reasonably high pressure. The mixture of fuel and air then ignites and burns rapidly. The gas in the chamber expands. This forces the piston to move down and thereby producing power stroke. The connecting rod which is linked to crankshaft forces it to turn and delivers rotary power at the output end of the crankshaft. Scavenging of the engine is completed either by ports or valves
Accessorizing a turbocharger is a vital accessory and is used to compress the intake air. To increase the efficiency an after cooler/intercooler is used to cool the air after compression. Speed of the engine can be controlled using Governor by adjusting the rate of fuel delivery. In cold weather conditions these Diesel Enginescan prove problematic. To overcome this problem small electric heater called glow plug is used inside the cylinder to warm the cylinders prior to starting. While you can also have resistive grid heaters in the intake manifold to warm the inlet air until the engine reaches operating temperature. Engine heaters fixed into the utility grid are mostly used when a Diesel Enginesis shutdown for long period in cold weather to lessen the startup time and engine wear.
