Diesel Engines: What You Need To Know
If you own a diesel-powered car, you probably value the intrinsic qualities of this type of engine. More torque, much better fuel economy, much easier maintenance are some of the attributes of owning a diesel-powered car. Still, some motorists 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 hurting fuel economy. Let’s take a look at diesel engines and what you can do to eject 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. However, with Diesel’s 1892 patent of the engine that bears his name, diesel power has played a substantial role in powering buses and trucks across the country. Some passenger vehicles, mainly pickup trucks, are also diesel-powered, offering motorists a choice to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to produce combustion versus the air/fuel mixture needed by Petroleum powered automobiles. This quality means that diesel engines 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 comparable petroleum-powered designs.
• Diesel engines are more affordable to maintain as they have fewer parts vs. a petroleum engine. The life expectancy of a diesel engine is also 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, particularly when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered car can manage the challenge.
So, why aren’t more vehicles in Lewisham diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so few manufacturers have improved upon the innovation to produce an environmentally friendly engine. However, numerous upcoming engines may change all of that.
Insufficient power. Yes, a common problem, even with turbo-diesel, is that the engines are not powerful enough. A lot of motorists 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.
Thankfully, numerous aftermarket product designers are assisting motorists 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 some of these aftermarket parts is that they don’t harm 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 newer, cleaner, and more powerful engines on the way, you may soon find yourself opting for a diesel-powered car too.

Diesel Engine Principles for Novices
Diesel engine principles are pretty straightforward for the experienced mechanic but what about routine everyday individuals who have never put in the time to find out more about a diesel engine and how it works?
In this short article, we are going to discuss in layman’s terms the fundamental 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 totally different. A Petrol engine is built much lighter than the heavier constructed diesel engine and operates 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 accurate time producing power and torque [turning force] which drives your car.
A diesel engine utilizes high compression [intake air that is compressed/squished] into an extremely small area inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which fires up an extremely 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 operates on four strokes or four cycles- both these terms mean the very same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open permitting 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 offering the diesel engine a boost 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 enables 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 accurate time.
3. Power Stroke:
After injection happens an explosion takes place 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 typical diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the formerly fired up gases to escape to the environment out the exhaust system.
As mentioned before, each cylinder goes through this precise sequence 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 passes, following the 4 strokes mentioned above. This sequence has been engineered to enable the diesel engine to run efficiently with no imbalance.
There is much to find out about diesel engines and a ton of details online. If you have ever considered purchasing a car 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 engines before you decide which one to pick.
