Diesel Engines: Cutting Emissions, Not Power

Latest article from Construction Europe (KLM group) – Despite the push for a new electric-powered market and hybrid engines coming onto the scene, it seems unlikely that diesel will be chiselled out of its spot as the number one engine power source for some time.

For over a hundred years, research and development have been invested into internal combustion engines, cementing their position as the lifeblood of large machinery.

Engine Reliability and cost

One company that firmly believes in diesel is Perkins, an engine manufacturer for nearly 90 years. In an interview with Construction Europe, Oliver Lythgoe of Perkin’s product concept marketing team explained how EU emissions regulations have shaped the engines of today.

He said, “One perception is that all the investment has gone into emissions and it hasn’t really turned into customer value, but I don’t think that’s true because some of the things you do for emissions create a lot of customer benefits.

“When you have to make a much better fuel system, then you end up getting a more powerful new engine.” It is certainly true to say that engines have benefitted from becoming more fuel-efficient and right now they are proving to be the most cost-effective method of powering a machine.

Why diesel isn’t dirty

The Diesel Technology Forum discusses the clean diesel journey – With a higher degree of certainty than ever before, we can say that diesel is a clean technology.
Diesel is a technology of continuous improvement and that goes for the fuel as well. Ultra-low sulfur diesel fuel has been the standard for both on-highway and off-highway diesel engines nationwide since 2007. By cutting sulfur levels in diesel fuel by 97 percent, immediate clean air benefits accrued – through lower soot emissions from all diesel vehicles and equipment using the fuel (both old and new) by 10 percent. Reducing the sulfur content of diesel fuel is similar to removing lead from gasoline during the 1970s.

Cleaner diesel fuel is the foundation that enabled the development and introduction of a new generation of advanced engines and emission control devices to meet strict “near zero” emissions standards.

120 years of diesel

BMW says diesel engines have at least 20 more years

At least 80% of 2025 sales will have an internal combustion engine.

A report from Automotive News quotes Klaus Frohlich, BMW Group board member for development, declaring that the diesel engine still has at least 20 more years, and the gasoline engine, at least 30 years. Also, he toned down the general rhetoric surrounding electric cars and their impending takeover.

What is next for boosting technology? Turbochargers?

Engine Technology International discusses the future of boosting. Using Turbochargers or superchargers started out as an exotic performance technology, now, turbocharging has become the default position for all diesel engines and the majority of today’s gasoline engines.

What does the future hold for turbochargers..

The future looks set to get a boost from both technologies, with turbocharger technology continuing on a similar path of improvement. VTG is already common in smaller diesel cars and two-stage turbo systems are now moving increasingly into that segment because of the economy benefits they offer.

Research and development in turbocharging has mainly been to reduce friction and inertia to improve response and driveability. Variable turbine geometry (VTG) have optimised  the compressor response at low engine speed when exhaust gas energy is low, while still delivering enough air during maximum load operation.

Two-stage turbocharging has been in use on premium diesels for a number of years. A smaller turbo gives good response at low engine speeds when exhaust energy is low, and a larger turbo takes over at high load to meet air mass requirements of high power and torque output. VTG remains somewhat of a rarity on gasoline engines, mainly due to the high temperatures involved, but it is starting to make an appearance.

“The obvious next step is the application of variable geometry turbines for both small and mid-size gasoline engines”
Nisar Al-Hasan, head of technical business development – turbocharger, Continental

The Future of Diesel – Emission Standard Changes

Diesel decline sees CO2 emissions rise

Article from the IAAF.

The Society of Motor Manufacturers and Traders (SMMT) has warned the average CO2 emissions have climbed almost three per cent to 124.5g/km.

The rise has been blamed on a diesel sales slump and experts say if CO2 emissions continue to rise it could have detrimental effects on the environment and also see countries miss their targets for slashing emissions.

Just over 750,000 new UK diesel cars were registered in 2018 compared to 1.06 million in 2017.

The overall market percentage of diesel cars also slumped from 42 per cent to under 32 per cent over the space of 12 months.
