Last year, Chevron covered a lot of territory bringing the conditions of Severe Duty to light, and highlighted many of the challenges of operating in these conditions.
Check out Part 1 of this series here. Despite the laundry list of engine types, the first step towards managing a mixed fleet well is quite simple: talk to the people who know the engines and lubricants first. Your OEM and lubricant providers are expert sources of information. They’ve seen every permutation of engine and […]
See Part 1 of this series here. In addition to regular checks to gauge the health of your coolant system, deeper system diagnostics should be conducted annually.
Coolant maintenance is an important part of an effective diesel engine reliability program. Most fleets and owner operators today tend to focus more time on their engine oil and other fluid performance intervals, but neglect their coolant maintenance.
Since the early 2000s, truck industry emission regulations have been primarily focused on reducing diesel particulate and NO emissions from diesel engines. With the advent of EPA2010 model engines using common rail fuel injection, lower EGR rates, DPF (Diesel Particulate Filters) and SCR (Selective Catalytic Reduction technology), OEMs have been able to significantly reduce […]
The truck manufacturing industry offers a wide variety of specifications, allowing any vehicle to be ideally adapted to the job it will do and the environment it will do it in. A similar principle applies to maintenance: It needs to be adapted to the application and environment, and off-road running may be the best example […]
Which fuel will be most cost-effective for your fleet depends upon many factors, including the flexibility and capability of your maintenance operation, and the fuels infrastructure where you refuel. Driver retention also is an issue as some types of engines perform better than others on the road.
More and different fuels are available to customers than ever before, a fact that is powerfully detailed in “Advancing Technology for America’s Transportation Future,” a DOE-sponsored study Chevron participated in. The advantages of these fuels for a fleet vary from cost management to activating their “green” strategy. We want to explore these choices and help […]
See parts 1 and 2 of this series here and here. In our last look at changing driving habits, we analyzed some of the stresses being placed on truck engines and some of the maintenance outcomes many people are seeing due to changes in haul length and driving styles. So what is a maintenance manager […]
See part 1 of this series here. Today’s trucks make shorter runs on average, according to the Bureau of Transportation Statistics (BTS) study. A shift to intermodal transportation, with railroads handling the long distance hauls, is the result of significantly higher fuel costs, a truck driver shortage, and more efficient rail service. While yesterday, trucks may […]
In recent years, the trucking industry has undergone a major shift as average haul lengths have decreased significantly nationwide. As recently as ten years ago, long-haul truckers made up the vast majority of the workforce in the trucking industry. Nowadays, average haul lengths have shrunk dramatically as businesses are faced with rising fuel prices, increased […]

SCR is a process that had been proven in stationary applications to reduce NOx in flue gas in powerplants. All the engine makers, with the exception of International, ended up specifying SCR for 2010, […]
See part 1 of this series here and part 2 here. Since the early days of increased EPA regulations, diesel engine technology had taken massive leaps forward in terms of fuel economy and emissions. However, diesel technology had progressed so far since the 1980s that further emissions reductions were very unlikely. By 2002, diesel truck […]
See Part 1 in this series here. 1998-2003 Engine developments came regularly as the years went by, made possible by continuing research into structural design, the use of finite element analysis, which refers to using computer power to examine each tiny sector of a structure, metallurgy, and the science of tribology. The latter refers to […]
It’s no secret – the most important contributor to the success of a trucking business is the durability, efficiency and cost-effectiveness of its equipment. Over the past few decades, diesel engine technology has come a long way, and technical innovations are one of the key drivers of continued business success. Innovations in truck diesel engines […]
