Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you probably appreciate the inherent qualities of this type of engine. More torque, much better fuel economy, simpler maintenance are a few of the attributes of owning a diesel-powered vehicle. Still, some drivers complain about the engine’s weak power, especially when accelerating from a full stop. What you may not know is that a diesel engine can be tweaked to produce more energy without harming fuel economy. Let’s take a look at diesel motors and what you can do to eject more power.
Thanks to the work of one man, Rudolf Diesel, we have a choice when it pertains to driving. Besides hybrid or rotary engines, the primary way most cars 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 considerable role in powering buses and trucks across the nation. Some passenger cars, mainly pickups, are likewise diesel-powered, providing drivers an alternative to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to produce combustion versus the air/fuel mix needed by Petroleum powered vehicles. This characteristic means that diesel engines do not need spark plugs and hence do not need to be tuned up.
• Diesel fuel has a greater fuel density than petroleum leading to fuel economy increases of 20-30% over similar petroleum-powered models.
• Diesel engines are less expensive to maintain as they have fewer parts vs. a petroleum engine. The lifespan of a diesel engine is likewise substantially longer.
If it is torque you need, especially for pulling a boat, camper, or equipment, then a diesel engine has the advantage. It is slower, specifically when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered vehicle can deal with the challenge.
So, why aren’t more cars in Freshwater diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so very few producers have improved upon the innovation to produce an environmentally friendly engine. However, 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. A lot of drivers 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 designers are assisting drivers eject more power from their diesel engines. Performance programmers, are assisting motorists in seeing a great spike in horsepower as well as increases in torque. The beauty of a few of these aftermarket parts is that they do not harm fuel economy. In fact, some claim to assist improve it.
Yes, the number of diesel-powered passenger cars currently on Australian highways is very little; nevertheless, with newer, cleaner, and stronger engines on the way, you may soon find yourself selecting a diesel-powered vehicle too.

Diesel Engine Principles for Newbies
Diesel engine principles are quite simple for the experienced mechanic but what about regular everyday people who have never taken the time to find out more about a diesel engine and how it works?
In this article, we are going to describe in layman’s terms the basic principles of a diesel engine. Let’s begin, shall we?
What’s the distinction 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 built much lighter than the much heavier developed diesel engine and operates 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 producing power and torque [turning force] which drives your vehicle.
A diesel engine uses high compression [intake air that is compressed/squished] into a very small area inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which fires up 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 uses ‘Heat of Compression’
The four-stroke principle
Every engine today operates on four strokes or four cycles- both these terms mean the exact same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open allowing pressurized air to enter each cylinder while the piston is traveling downward.the the pressurized air supply is made possible by the TURBOCHARGER which presses air into the intake system providing the diesel engine an increase of air to stay up to date with an immediate injection of fuel
2. Compression Stroke:
When the piston starts to make its way back up 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 takes place a surge takes place in the cylinder because of the combination of heat and atomized diesel fuel. This causes the piston to be forced downward which produces torque and the horsepower needed from a typical diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open allowing the previously fired up gases to escape to the atmosphere out the exhaust system.
As discussed before, each cylinder goes through this specific series over and over in a set firing order. For instance, a 6 cylinder diesel engine has a firing order of 1- 5- 3- 6- 2- 4 which is the order that each cylinder goes through, following the 4 strokes discussed above. This series has been crafted to allow the diesel engine to run efficiently without any imbalance.
There is much to find out about diesel engines and a ton of info online. If you have ever thought about purchasing 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 motors before you choose which one to select.
