How to improve diesel car efficiency

Several things can be done to improve efficiency in diesel cars, including improving their fuel economy, increasing the power of the vehicle, and reducing emissions. Diesel engines have long been used for commercial transport purposes because they are capable of delivering high torque at low speeds compared with gasoline engines which makes them ideal for heavy loads and large vehicles. However, diesel engines also emit higher levels of NOx and soot particles than gasoline engine vehicles.

Using a diesel particulate filter (PDF)

Since the amount of fuel burnt in an engine is directly linked to the power produced by that engine, then optimizing or improving that burn has a direct effect on the efficiency of the vehicle. There are several ways to do this. One of the most effective is the use of a diesel particulate filter (PDF). A Diesel Particulate Filter is a device designed to remove soot particles from the exhaust of an engine. It has been adopted as many diesel engines as they contribute to high fuel efficiency and power production capabilities due to their ability to reach high engine temperatures. The PDF uses a ceramic core to trap the soot particles in an attempt to reduce NOx and particulate matter (PM) in diesel engines, which are known for their environmental effects including acid rain, smog, and global warming. However, when it becomes completely clogged with ash, which can occur when driving conditions are severe, the PDF must be regenerated to maintain its effectiveness. This is achieved either by burning off the trapped particles in a process known as passive regeneration or actively burning them with additional fuel injected into the filter using what is called active regeneration. The latter process can use significant amounts of diesel fuel and it may be necessary to switch off any other fuel-burning devices such as a turbocharger when active regeneration is occurring to save fuel. It is also known that regenerating the PDF can produce significant amounts of soot and NOx which must be filtered out using the SCR system.

Using low viscosity lubricants for the engine

A second method for improving efficiency in diesel engines is using low viscosity lubricants for the engine. Lubricants reduce friction and heat damage and improve the fuel economy of an engine by reducing rotating losses, where compressed air absorbs mechanical energy. This is achieved through improved atomization of fuel injected into the combustion chamber which mops up more oil from the parts being lubricated as well as helping to form a protective thermal barrier on those surfaces.

Use of “bio-diesel”

The use of “bio-diesel” is also gaining momentum in the transportation industry due to its environmental benefits compared with petroleum-based diesel fuels. Bio-diesel can be produced from vegetable oils, animal fats, waste cooking oil, and algae fuel. It is typically blended with petro-diesel in any concentration for it to be used by existing diesel engines. It can be combined with petro-diesel in any proportion which results in a blend that can be used as ‘drop-in’ fuel or as an alternative fuel, depending on the legislation of each region. The type of fuel and feedstock is suitable for different engine types and optimum performance should be investigated before switching to bio-diesel.

Although steam engines and diesel engines may seem like ancient and obsolete technologies, they are still very relevant in the present day. Industrial machinery such as locomotives and ships have been using them for many decades due to their high power-to-weight ratio when compared with internal combustion engines. It is unlikely that they will ever be replaced by electric engines as their simplicity and efficiency are difficult to beat. In addition, there are many applications for steam power that do not require a highly-efficient engine such as powering pumps on a train or ship or recharging batteries with excess capacity. These ongoing developments in power production have revolutionized the world we live in and will continue to do so.

Turn your engine off

Shut off idling when you’re stopped. If the car is stopped for more than 30 seconds, shut off your engine. This can help save fuel and avoid excess emissions when stopped at a traffic light or in heavy traffic. Save gas with regenerative braking systems (RBS). RBS harnesses the energy that would otherwise be lost during the braking process and returns it to an energy storage system. RBS can provide a more efficient drive by drawing on this energy storage system instead of relying on conventional brake pads.

Use tires with low rolling resistance.

Use tires with low rolling resistance. These tires cut down on your fuel consumption by reducing the amount of drag a car experiences when moving forward. There’s no definitive way to tell if the tires you’re using are low-rolling resistance, but some experts recommend looking for a “starburst” symbol on the sidewall that indicates they meet the guidelines of America’s Promise initiative. The more stars, the better your tire is at reducing fuel consumption.

Use cruise control to help achieve optimal mileage.

Use cruise control to help achieve optimal mileage. Cruise control can help reduce the amount of throttle you use as well as help keep a steady speed. That can help reduce fuel consumption, which can lead to more savings for you and fewer emissions wasted. Drive at a lower RPM. Driving at low RPMs will not only help improve the MPG, but it does so while minimizing wear and tear on your engine.

Don’t accelerate too quickly

Don’t accelerate too quickly. This may seem like a contradiction of the first tip, but it is just as bad to floor the gas from a stoplight to get away from being rear-ended as it is to fly off the starting line at a green light. Both situations will cause the engine to surge, which means you are asking for trouble.

Turning off your air conditioner

Air-conditioning puts a heavy load on the engine, especially when idling waiting for traffic signals, or stopping in bumper-to-bumper traffic. It is better to roll down the windows and rely on the ambient air circulating through your car until driving conditions improve.

Reducing unnecessary auxiliary loads

Any electrical device in your car that you are not using reduces the engine’s efficiency because it is creating extra load on the alternator, which then has to work that much harder to keep up with demand when running at highway speeds. Turn off fans, lights, and other electronics to conserve power and reduce the load on the engine.

Driving to your vehicle’s torque peak

The diesel engine can be a tricky beast because it takes a while for everything to get going, but once that momentum is built up you’re good to go. You don’t need to rev the heck out of this engine like you would in a gasoline car.

Conclusion

The diesel engine can be a tricky beast because it takes a while for everything to get going, but once that momentum is built up you’re good to go. 

The new technology has been applied to diesel since 2010 and consists of using an additive called urea (small amount) injected into the exhaust stream. The use of low viscosity lubricants for the engine will also help increase efficiency in your diesel car, both by helping reduce friction in the engine parts under pressure and heat and by reducing power requirements from the engine itself. It turns out that putting low viscosity oil in your diesel engine can actually make it more efficient and reduce emissions as well. The first thing that comes to mind when you think about reducing emissions is changing out your old clunker of a car for a new hybrid or electric one, but there are several things you can do on your current vehicle to cut down on emissions and improve efficiency.
