New Laws will Double the Biofuel Output in Britain

Tuesday, April 17, 2018

Diesel engines are much more prevalent in Europe than in the United States, however that love affair has softened in recent years. In the wake of the VW “Dieselgate” as well as increased environmental pressure from regulators, diesel has had a bit of an image problem. Great Britain is moving forward from its reliance on diesel with a new biofuels program. The British Biofuel sector hopes to double the use of renewable fuels in the over-the-road trucking industry within the next 15 years and significantly reduce the amount of diesel fuel imported into the country. ... read more »

Common Differences Between Marine and Industrial Diesel Engines

Friday, October 6, 2017

There is no standard diesel engine for every application. For example there are industrial applications, truck application, electrical power generation, RV applications, heavy duty emergency, pumps and of course marine applications. Although, each engine is slightly different the core design is the same. The exhaust, cooling, electrical and fuel systems are all different in marine engines. This article will discuss the differences between industrial diesel engines and their marine counterparts. ... read more »

Mack Goes All In With Alternative to Diesel Fuel: DME

Monday, September 18, 2017

Technology is progressing at an ever increasing rate. The future is now! It seems you can’t go a day without reading about robots, self driving cars or even the new Hyperloop projects which will transport people hundreds of miles in mere minutes. Many of those in the automotive and transportation sectors believe diesel engines best days are behind them. A team of scientists however believe there is still use left for the diesel engines in the world of tomorrow. A team of researchers at Queen’s University in Belfast, Ireland are working on a different fuel source for the engines known as Dimethyl Ether (DME). DME is a biofuel derived from methane. Methane is commonly captured from decomposing organic material, agriculture, waste and coal and reused as a fuel source. DME is viewed as a clean diesel fuel source and will be able to be used with existing diesel engines. ... read more »

China Bans High Sulphur Diesel

Thursday, July 6, 2017

China has a notorious reputation for extremely polluted air. The air quality is so bad most days that citizens must wear masks outdoors. As the country evolves, tackling the emission issue has become a primary issues for the government. It was announced on June 30th that China will join the rest of the modern world by banning general diesel fuel with Sulphur containing more than 50 parts per million. The diesel fuel will ban will affect tractors, ships and off-road vehicles rather than automobiles. ... read more »

Cummins N14 Specs, History and Problems

Friday, June 16, 2017

The Cummins N-14 is a great engine; quite possibly the best Cummins engine ever produced. These engines are the stuff dreams are made of if you’re an old school guy looking for reliability. No doubt, the N14 is part of “1,000,000 mile club”. The engine features the best of engineering fundamentals mixed with one of the first electronic control system. First designed in the late 1980s it was sent into full production in 1991. The N14 engine is the follow up to the vastly popular Cummins 855 Big Cam which was produced 1976-1985. Cummins listened to it customers and designed a more powerful version of the 855 while maintaining a similar profile and bore/stroke architecture. Overall, the biggest structural difference between the 855 and N14 is the air-to-air cooling system changes but both engines are very similar. ... read more »

New Diesel Emissions Technology Unveiled - ACCT

Wednesday, May 31, 2017

We all know of the emissions issues that surround the diesel engine community. It has been a battle between the EPA, Manufacturers and Consumers for well over 20 years now. Physics.org has just broken a story that might revolutionize the industry in terms of emissions control. Scientists at Loughborough University’s School of Mechanical, Electrical and Manufacturing Engineering have developed new technology that further converts NOx exhaust into harmless nitrogen and water. The problem with current emissions technology is that it doesn’t fully burn emissions particles a lower temperature points. The standard Selective Catalytic Reduction System (SCR) takes exhaust gas and further recirculates it through the combustion chamber to burn off larger hydrocarbon chains. ... read more »

Rolling Coal Ban Enacted in Colorado

Thursday, May 25, 2017

Rollin’ Coal… nothing more wild than driving down the highway blasting a little black smoke from 7 inch chrome stacks. There has been much debate in recent years as to the health and well being of general public. Rolling Coal itself is not illegal however as of July 2014 the EPA stated that any modifications that bypass or defeats or renders emission control systems is illegal. Older manual pre-emissions engines, without modern day emission systems, have been grandfathered in and thus street legal. All vehicles regardless of modifications must pass emissions requirements per the year they were manufactured. ... read more »

Ultra Low Sulfur Diesel Information

Friday, April 7, 2017

The diesel engine industry has encountered many changes over the past 20 years or with the advent of the EPA Tier Emissions Regulations on first enacted in 1994. Since then, the regulations and standards of allowable NOx emissions have gotten more strict thus forcing engine manufacturers to make drastic engineering changes to their products. The early years were difficult for the manufactures as emissions technology was often cumbersome, prone to maintenance issues and expensive. However, the DPF, EGR and SCR systems have all gotten much better as the major players in the industry learned to adapt. ... read more »

Big Win For John Deere Owners Over ECM Modifications

Friday, March 31, 2017

CAT C7 Specs and Engine History

Friday, March 10, 2017

At the turn of the century there was a lot of buzz around a new diesel engine being produced at Caterpillar, one that could meet the growing emissions requirements enacted by the EPA. The Caterpillar C7 Engine was supposed to be the “golden child” in Caterpillar diesel engine lineup; one that combined raw horsepower with computer controlled clean emissions. However, sometimes things don’t go according to plan. The engine was produced from 2003 to 2009 and was installed primarily in over the road medium duty class 8 trucks. All of the big players in the trucking industry hopped on board hoping the CAT C7 was going to live up to the hype. Paccar Freightliner, Ford and GMC all purchased the engine in droves ... read more »
