This translates into an engine that produces more horsepower and torque per gallon of fuel than a traditional powered gas engine. The announcement is thrilling environmental activists as this means less harmful emissions output per engine as well as less trips to gas station. Diesel engines for passenger vehicles have been widely popular in Europe years but not so much in the American market. Diesels have the perception of being noisy and polluters. The VW Dieselgate Scandal only further solidified the anti-diesel attitude in America. This new gas powered engine would allow all of the advantages of diesel minus any of the image problems. Some industry analysts have speculated that the only drawback could be the safety concerns with regards to fuel leaks through the cylinders. With diesel it is non-flammable unless it is compressed however a raw gasoline leak on the block or valves could potentially cause major engine fires. Hopefully, Mazda engineers have addressed this issue but this technology is in its infancy. Mazda is proactively thinking about its place in the automotive marketplace of the future. The company announced a plan to build electric cars with rival automaker Toyota. Mazda believes that both traditional combustion engines as well as electric engines will be the lay of the land for the foreseeable future. ... read more »

Each week here at Capital Reman is different in its own way. This week we shipped out 5 engines and had an awesome week production-wise. Everyone is working well as a team and it is really showing in the quality we are putting out the door. Our old pal Dennis Gordon did great in his new role as Director of Operations. Here are a few pictures of the guys in action. Thanks again to all of our loyal customers and vendors. ... read more »

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 »

Electronic engines get a bad rap in the heavy duty diesel engine world due to the amount of issues that can go wrong with them. However, the good news is that if you have an electronic Caterpillar engine you can easily obtain more horsepower and torque via the ECM. Re-rating an engine is an electronic process of powering up or down the default horsepower via the electronic control module (ECM). Re-rating a diesel engine is the easiest way to beef up an engine without digging into the hard internal parts. You can do modifications to the engine by changing out the pistons, injectors, the camshaft or damper. Adding an updated turbo is also another way to increase HP. However, these modifications are expensive and may not work as required which we will discuss later in this article. ... read more »

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 »

We here at Capital Reman are experts at grinding and remanufacturing diesel crankshafts. Crankshaft grinding consists of removing a minute amount of finished material from the rod and main journals to rebuild the part back to OEM spec. The full 25 step crankshaft remanufacturing process is quite intensive but is critical to complete engine rebuild. This article will explain the main components of a crankshaft’s design as well as the finer points of crankshaft remanufacturing. ... read more »

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 »

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 »

Technology continues to integrate itself in the diesel engine industry. The old guard is on its way out and 21st century technology is alive and well over at Cummins, Inc. The company announced the release of its new Guidanz mobile app which allows customers to access engine fault code and diagnostics within minutes. ... read more »

A brand new diesel engine running at full load will experience a little bit of blow-by upon startup. Blow-by is a condition where diesel fuel, air and vapor are pushed past the rings into the crankcase of the engine. Correct pressure should be maintained in the cylinder chamber in order for proper combustion to occur. In a new diesel engine the rings need time to seat properly and develop an air-tight seal. After a short period of break-in hours under load, the blow-by problem should correct itself. Consequently, a proper running diesel engine should produce no visible smoke from the exhaust. If there is smoke coming from the exhaust it could indicate a more serious problem with the engine. This article will help diagnose the underlying causes of diesel engine smoke. ... read more »
