Diesel Engines: What You Need To Know

dieseljectIf you own a diesel-powered automobile, you probably appreciate the inherent qualities of this type of engine. More torque, better fuel economy, simpler maintenance are a few of the attributes of owning a diesel-powered automobile. Still, some vehicle drivers complain about the engine’s weak power, particularly when accelerating from a full stop. What you may not know is that a diesel motor can be fine-tuned to produce more energy without harming fuel economy. Let’s take a look at diesel engines and what you can do to squeeze out more power.
Thanks to the work of one man, Rudolf Diesel, we have a choice when it concerns driving. Besides hybrid or rotary engines, the primary way most automobiles run is by means of a petroleum-powered internal combustion engine. Nevertheless, with Diesel’s 1892 patent of the engine that bears his name, diesel power has played a substantial role in powering buses and trucks throughout the nation. Some passenger vehicles, primarily pickup trucks, are also diesel-powered, giving vehicle drivers an option to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to create combustion versus the air/fuel mixture needed by Petroleum powered cars and trucks. This characteristic means that diesel motor do not need spark plugs and hence do not have to be tuned up.
• Diesel fuel has a higher fuel density than petroleum resulting in fuel economy increases of 20-30% over equivalent petroleum-powered models.
• Diesel engines are more affordable to maintain as they have less parts vs. a petroleum engine. The life-span of a diesel engine is also considerably longer.
If it is torque you need, particularly for pulling a boat, camper, or equipment, then a diesel motor has the advantage. It is slower, particularly when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered automobile can handle the difficulty.

So, why aren’t more vehicles in Thornleigh diesel-powered?

Some of the reasons include:

Stricter emissions control standards: Diesel engines pollute more, so not many manufacturers have improved upon the innovation to produce an eco-friendly engine. Nevertheless, a number of upcoming engines may change all of that.
Not enough power. Yes, a typical complaint, even with turbo-diesel, is that the engines are not powerful enough. Many chauffeurs are accustomed to getting on the highway with a minimum amount of effort. With a diesel engine, it can take as much as two times as long to get up to full speed.

Luckily, a number of aftermarket product developers are assisting vehicle drivers squeeze out more power from their diesel engines. Efficiency programmers, are helping motorists in seeing a nice spike in horse power along with increases in torque. The beauty of a few of these aftermarket parts is that they do not hurt fuel economy. In fact, some claim to help improve it.
Yes, the variety of diesel-powered passenger automobiles presently on Australian highways is very little; however, with more recent, cleaner, and stronger engines on the way, you may soon find yourself going with a diesel-powered automobile too.

Diesel Engine Principles for Beginners

Diesel engine principles are pretty direct for the experienced mechanic but what about regular everyday individuals who have never taken the time to find out more about a diesel engine and how it works?
In this post, we are going to explain in layman’s terms the basic principles of a diesel engine. Let’s begin, shall we?
What’s the difference between the petrol engine and a diesel engine?
The first thing you should understand is a petrol engine and a diesel engine are totally different. A Petrol engine is constructed much lighter than the heavier built diesel engine and runs on an air/fuel mixture combined with a high energy spark that is timed to ignite the air/fuel mixture inside each engine cylinder at the exact time developing power and torque [turning force] which drives your automobile.
A diesel engine utilizes high compression [intake air that is compressed/squished] into a very small space inside each cylinder triggering severe heat! This is called ‘Heat of Compression’ which ignites a very fine high-pressure mist of diesel fuel that is injected into the cylinder at the exact time.
So you now understand that a gpetrol engine needs a high energy spark to run while a diesel utilizes ‘Heat of Compression’
The four-stroke principle
Every engine today runs on 4 strokes or 4 cycles- both these terms mean the same. Here is how the four-stroke diesel engine runs.
1. Intake Stroke:
Intake valves in the cylinder head open permitting pressurized air to enter each cylinder while the piston is traveling downward.the the pressurized air supply is enabled by the TURBOCHARGER which pushes air into the intake system giving the diesel engine a boost of air to keep up with an instant injection of fuel
2. Compression Stroke:
When the piston starts to make its way back upward the valves close which traps the intake air in the cylinder which permits compression to take place, the HEAT OF COMPRESSION is reached when the piston reaches the top of the cylinder, the diesel fuel is then injected into the cylinder at the exact time.
3. Power Stroke:
After injection occurs a surge occurs in the cylinder because of the combination of heat and atomized diesel fuel. This triggers the piston to be forced downward which produces torque and the horse power needed from a common diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the previously fired up gases to escape to the environment out the exhaust system.
As pointed out before, each cylinder goes through this specific sequence over and over in a set firing order. For example, a 6 cylinder diesel engine has a firing order of 1- 5- 3- 6- 2- 4 which is the order that each cylinder passes, following the 4 strokes pointed out above. This sequence has been engineered to enable the diesel engine to run efficiently with no imbalance.
There is much to learn about diesel engines and a ton of details online. If you have ever considered purchasing a vehicle with a diesel engine you have made a prudent decision! The extra cost will be to your benefit, so it is recommended that you find out more about diesel engines before you choose which one to pick.
