Diesel Engines: What You Need To Know
If you own a diesel-powered automobile, you most likely appreciate the inherent qualities of this kind of engine. More torque, much better fuel economy, easier maintenance are a few of the attributes of owning a diesel-powered automobile. Still, some motorists grumble about the engine’s weak power, especially 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 motors 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 vehicles run is via 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, providing motorists a choice to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to develop combustion versus the air/fuel mix required by Petroleum powered cars. This characteristic means that diesel engines do not need spark plugs and thus do not have 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 cheaper to maintain as they have less parts vs. a petroleum engine. The life expectancy of a diesel engine is also significantly longer.
If it is torque you need, especially for pulling a boat, camper, or equipment, then a diesel motor has the advantage. It is slower, especially when starting from a dead stop, but when climbing hills or going over bridges, your diesel-powered automobile can handle the difficulty.
So, why aren’t more vehicles in Narraweena diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so very few manufacturers have improved upon the technology to produce an environmentally friendly engine. Nevertheless, numerous upcoming engines may change all of that.
Not enough power. Yes, a typical problem, even with turbo-diesel, is that the engines are not powerful enough. Most 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 designers are helping motorists squeeze out more power from their diesel engines. Performance developers, are helping motorists in seeing a good 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 more recent, cleaner, and more powerful engines on the way, you may soon find yourself selecting a diesel-powered automobile too.

Diesel Engine Principles for Novices
Diesel engine principles are quite direct for the experienced mechanic but what about regular everyday people who have never put in the time to find out more about a diesel engine and how it works?
In this post, 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 constructed much lighter than the much heavier constructed diesel engine and operates on an air/fuel mix integrated 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 automobile.
A diesel engine uses high compression [intake air that is compressed/squished] into a really small space inside each cylinder causing extreme heat! This is called ‘Heat of Compression’ which fires up a really 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 4 strokes or 4 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 permitting pressurized air to enter 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 providing the diesel engine an increase of air to stay up to date with an instantaneous injection of fuel
2. Compression Stroke:
When the piston begins to make its way back upward 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 takes place a surge takes place in the cylinder because of the mix of heat and atomized diesel fuel. This causes the piston to be forced downward which produces torque and the horsepower required from a typical diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the previously sparked gases to escape to the environment out the exhaust system.
As discussed before, each cylinder goes through this exact 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 goes through, following the 4 strokes discussed above. This sequence has been engineered to permit the diesel engine to run efficiently with no imbalance.
There is much to learn about diesel engines and a lots of information online. If you have ever thought about purchasing a vehicle with a diesel engine you have made a prudent decision! The extra cost will be to your advantage, so it is recommended that you find out more about diesel motors before you choose which one to pick.
