Diesel Engines: What You Need To Know

dieseljectIf you own a diesel-powered vehicle, you probably appreciate the intrinsic qualities of this type of engine. More torque, better fuel economy, easier maintenance are a few of the qualities of owning a diesel-powered vehicle. Still, some motorists grumble about the engine’s weak power, particularly when accelerating from a full stop. What you may not know is that a diesel engine can be modified to produce more energy without hurting fuel economy. Let’s have 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 main way most vehicles run is by means of a petroleum-powered internal combustion engine. However, with Diesel’s 1892 patent of the engine that bears his name, diesel power has played a significant role in powering buses and trucks throughout the nation. Some passenger vehicles, mainly pickup trucks, are also diesel-powered, giving motorists an alternative to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to develop combustion versus the air/fuel mix needed by Petroleum powered vehicles. This quality means that diesel motor do not need spark plugs and hence do not need to be tuned up.
• Diesel fuel has a higher fuel density than petroleum leading to fuel economy boosts of 20-30% over equivalent petroleum-powered models.
• Diesel engines are cheaper to maintain as they have fewer parts vs. a petroleum engine. The lifespan of a diesel engine is also significantly longer.
If it is torque you need, particularly for pulling a boat, camper, or equipment, then a diesel engine 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 vehicle can manage the obstacle.

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

Some of the reasons include:

Stricter emissions control standards: Diesel engines contaminate more, so few manufacturers have improved upon the technology to produce an environmentally friendly engine. However, numerous upcoming engines may change all of that.
Insufficient power. Yes, a typical grievance, 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 twice as long to get up to full speed.

Luckily, numerous aftermarket product developers are assisting motorists squeeze out more power from their diesel engines. Performance developers, are helping motorists in seeing a nice spike in horsepower as well as increases in torque. The beauty of a few of these aftermarket parts is that they don’t damage fuel economy. In fact, some claim to help improve it.
Yes, the number of diesel-powered passenger vehicles currently on Australian highways is very little; nevertheless, with newer, cleaner, and stronger engines on the way, you may soon find yourself choosing a diesel-powered vehicle too.

Diesel Engine Principles for Beginners

Diesel engine principles are quite simple for the experienced mechanic but what about regular everyday individuals who have never made the effort to find out more about a diesel engine and how it works?
In this article, we are going to explain in layperson’s terms the standard principles of a diesel engine. Let’s start, shall we?
What’s the difference between the petrol engine and a diesel engine?
The first thing you should know is a petrol engine and a diesel engine are absolutely different. A Petrol engine is built much lighter than the heavier developed diesel engine and works on an air/fuel mix combined with a high energy spark that is timed to fire up the air/fuel mix inside each engine cylinder at the exact time developing power and torque [turning force] which drives your vehicle.
A diesel engine utilizes high compression [intake air that is compressed/squished] into a very little area inside each cylinder triggering severe heat! This is called ‘Heat of Compression’ which sparks a very fine high-pressure mist of diesel fuel that is injected into the cylinder at the exact time.
So you now know 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 works on 4 strokes or 4 cycles- both these terms mean the same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open enabling pressurized air to get in each cylinder while the piston is traveling downward.the the pressurized air supply is made possible by the TURBOCHARGER which pushes air into the intake system giving the diesel engine a boost of air to keep up with an instantaneous injection of fuel
2. Compression Stroke:
When the piston begins to make its way back up the valves close which traps the intake air in the cylinder which allows compression to happen, 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 an explosion takes place 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 horsepower needed from a common diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open enabling the formerly fired up gases to escape to the environment out the exhaust system.
As mentioned before, each cylinder goes through this exact series 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 mentioned above. This series has been engineered to enable the diesel engine to run smoothly without any imbalance.
There is much to learn about diesel engines and a ton of information online. If you have ever thought about buying a car 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 select.
