Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you most likely appreciate the inherent qualities of this type of engine. More torque, better fuel economy, easier maintenance are some of the attributes of owning a diesel-powered vehicle. Still, some motorists complain about the engine’s weak power, especially when accelerating from a full stop. What you might not know is that a diesel motor can be tweaked 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 comes to driving. Besides hybrid or rotary engines, the main way most cars run is through a petroleum-powered internal combustion engine. Nevertheless, 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, generally pickups, are likewise diesel-powered, providing motorists an option to petroleum.
Diesel engines have the following benefits over their petroleum counterparts:
• Diesel use air compression to develop combustion versus the air/fuel mixture needed by Petroleum powered vehicles. This characteristic means that diesel motor do not need spark plugs and therefore do not have to be tuned up.
• Diesel fuel has a greater fuel density than petroleum resulting in 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 considerably 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, particularly when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered vehicle can deal with the obstacle.
So, why aren’t more cars in Longueville 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, several upcoming engines might change all of that.
Insufficient 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 two times as long to get up to full speed.
Luckily, several aftermarket product designers are assisting motorists squeeze out more power from their diesel engines. Efficiency programmers, are helping motorists in seeing a nice spike in horsepower as well as increases in torque. The beauty of some of these aftermarket parts is that they do not damage fuel economy. In fact, some claim to help improve it.
Yes, the number of diesel-powered passenger cars currently on Australian highways is very little; nevertheless, with more recent, cleaner, and more powerful engines on the way, you might soon find yourself choosing a diesel-powered vehicle too.

Diesel Engine Principles for Beginners
Diesel engine principles are quite straightforward 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 post, we are going to discuss in layperson’s terms the basic principles of a diesel engine. Let’s start, shall we?
What’s the distinction between the petrol engine and a diesel engine?
The first thing you should know is a petrol engine and a diesel engine are completely different. A Petrol engine is built much lighter than the much heavier developed diesel engine and operates on an air/fuel mixture combined with a high energy spark that is timed to fire up the air/fuel mixture 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 really little area inside each cylinder causing extreme heat! This is called ‘Heat of Compression’ which sparks a really 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 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 runs.
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 enabled 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 immediate 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 happens in the cylinder because of the mix of heat and atomized diesel fuel. This triggers the piston to be forced downward which produces torque and the horsepower needed from a normal diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open enabling the previously fired up gases to escape to the atmosphere out the exhaust system.
As discussed before, each cylinder goes through this exact 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 enable the diesel engine to run smoothly without any imbalance.
There is much to learn about diesel engines and a ton of details online. If you have ever considered purchasing an automobile with a diesel engine you have made a prudent decision! The additional cost will be to your advantage, so it is recommended that you find out more about diesel engines before you choose which one to select.
