Turbocharging is already a key part of heavy duty diesel engine technology. However, the need to meet emissions regulations is rapidly driving the use of turbo diesel and turbo gasoline engines for passenger vehicles. Turbocharged diesel engines improve the fuel economy of baseline gasoline engine powered passenger vehicles by 30-50%. Turbocharging is critical for diesel engine performance and for emissions control through a well designed exhaust gas recirculation (EGR) system. In gasoline engines, turbocharging enables downsizing which improves fuel economy by 5-20%.

In order to evaluate the opportunities to use hybrid concepts for heavy commercial vehicles for emerging markets, MAN Latin America has developed a VW refuse truck with 23t GVW using the hybrid hydraulic technology. In site vehicle tests measurements has indicated a fuel savings up to 25%, which means a reduction around 4.08 liters of diesel/hour or 20 tones CO2/year . Thus, a collaborative cooperation with Rio de Janeiro Sanitation Department (Comlurb) was set for a truck evaluation on a real operation. This 03-month evaluation used one VW 17.280 6x2 hybrid hydraulic refuse truck and other VW refuse truck similar standard diesel. A random dispatch system ensures the vehicles are used in a similar manner. Global positioning system logging, fueling, and maintenance records are used to evaluate the performance of this hybrid hydraulic refuse truck.

A study was funded by NHTSA to help inform the Phase 2 GHG and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles. The goal of the study was to review technologies that could be used by Class 2b through Class 8 trucks to comply with possible future regulatory requirements, and determine their potential performance. The vehicles and engines selected for the study had extensive experimental data available from earlier work. The four trucks were a Kenworth T700 tractor, a Kenworth T270 box delivery truck, a Ford F-650 tow truck, and a Ram 2500 / 3500 pickup. For the long haul tractor, a Detroit DD15 engine was used. The pickup and medium-duty trucks used two different ratings of the Cummins ISB diesel, as well as a 6.2 liter naturally-aspirated gasoline V-8 and a turbocharged, direct-injected 3.5 liter gasoline V-6. All engine simulations were performed with GT-POWER.

The United States Environmental Protection Agency’s (EPA’s) National Center for Advanced Technology (NCAT), located at its National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan, has been known for its development and demonstration of numerous low-greenhouse gas and fuel efficient series hydraulic hybrid drivetrain technologies and their application in commercial vehicles. Advances in these very fuel efficient hydraulic hybrid vehicle technologies have led the industry to begin manufacturing these exciting new technologies for both the commercial truck and non-road equipment markets, with development activities continuing in other markets including light-duty vehicles. The commercial emergence of these very low-greenhouse gas emitting hybrids led EPA to decide that the time had come to wind down its leadership role in developing and demonstrating these very fuel efficient technologies.

Lift axles increase the load capacity of a vehicle, allowing it to carry the extra load without the need for multiple vehicles, hence reducing operational costs. Furthermore, additional axles help to distribute the truck’s load across the road surface, reducing the chances of damage to the infrastructure. Lift axles can be raised when the vehicle has lighter load to save fuel and reduce wear and tear to the tires and axles. They can be deployed to improve traction especially in icy off-road applications. The main objective of this project was to assess the fuel-saving potential of lifting axles on unloaded semi-trailers. Part of the mandate was to identify and analyze regulations of various jurisdictions with respect to lift/loadable axles and studies leading to the setting up of these regulations. The SAE Fuel Consumption Test Procedures Type II (J1321) was used for fuel consumption track test evaluations.

Abstract For decades, the medium- and heavy-duty (“MD/HD”) commercial vehicle industry has focused on improving freight efficiency in order to lower customers' total operating costs. To optimize fuel efficiency, most manufacturers no longer focus on discreet components but instead look at the complete vehicle and operations. The path to future efficiency gains is not sufficiently clear when looking towards 2030; what is clear is that one solution will not work for all manufacturers or vehicle applications. Therefore, fuel efficiency regulations must be sufficiently adaptive to allow a variety of technical approaches to ensure the needs of the commercial truck market are met. This paper explores further the ideas presented in other papers that focus on regulation of engine-only emissions as an approach for HD vehicles.

Abstract In the near future engine emitted carbon dioxides (CO2) are going to be limited for all vehicle categories with respect to the Green House Gases (GHG) norms. To tackle this challenge, new concepts need to be developed. For this reason waste heat recovery (WHR) is a promising research field. For commercial vehicles the first phase of CO2 emission legislation will be introduced in the USA in 2014 and will be further tightened towards 2030. Besides the US, CO2 emission legislation for commercial engines will also be introduced in Europe in the near future. The demanded CO2 reduction calls for a better fuel economy which is also of interest for the end user, specifically for the owners of heavy duty diesel vehicles with high mileages. To meet these future legislation objectives, a waste heat recovery system is a beneficial solution of recovering wasted energies from different heat sources in the engine.

Cylinder deactivation (CDA) is an effective method to adjust the engine displacement for maximum output and improve fuel economy by adjusting the number of active cylinders in combustion engines. A Switching Roller Finger Follower (SRFF) is an economic solution for CDA that minimizes changes and preserves the overall width, height, or length of Dual Overhead Cam (DOHC) engines. The CDA SRFF provides the flexibility of either transferring or suppressing the camshaft movement to the valves influencing the engine performance and fuel economy by reducing the pumping losses. This paper addresses the performance and durability of the CDA SRFF system to meet the reliability for gasoline passenger car engines. Extensive tests were conducted to demonstrate the dynamic stability at high engine speeds and the system capacity of switching between high and low engine displacement within one camshaft revolution.

Abstract Market driven competition in global trade and urgency for controlling the atmospheric air pollution are the twin forces, which have urged Indian automobile industries to catch up with the international emission norms. Improvement in the fuel efficiency of the vehicles is one way to bind to these stringent norms. It is experimentally proven that almost 40% of the available useful engine power is being consumed to overcome the drag resistance and around 45% to overcome the tire rolling resistance of the vehicle. This as evidence provides a huge scope to investigate the influence of aerodynamic drag and rolling resistances on the fuel consumption of a commercial vehicle. The present work is a numerical study on the influence of aerodynamic drag resistance on the fuel consumption of a commercial passenger bus. The commercial Computational Fluid Dynamics (CFD) tool FLUENT™ is used as a virtual analysis tool to estimate the drag coefficient of the bus.

Abstract As part of the United States Department of Energy's SuperTruck program, Volvo Trucks and its partners were tasked with demonstrating 50% improvement in overall freight efficiency for a tractor-trailer, relative to a best in class 2009 model year truck. This necessitated that significant gains be made in reducing aerodynamic drag of the tractor-trailer system, so trailer side-skirts and a trailer boat-tail were employed. A Lattice-Boltzmann based simulation method was used in conjunction with a Kriging Response Surface optimization process in order to efficiently describe a design space of seven independent parameters relating to boat-tail and side-skirt dimensions, and to find an optimal configuration. Part 1 concerns a fully-skirted tractor-trailer system, and consists of an initial phase of optimization, followed by a mid-project re-evaluation of constraints, and an additional period of optimization.

Abstract Fuel economy is one of the major challenges for both on and off-road vehicles. Inefficient engine operation and loss of kinetic energy in the form of heat during braking are two of the major sources of wasted fuel energy. Rising energy costs, stringent emission norms and increased environmental awareness demand efficient drivetrain designs for the next generation of vehicles. This paper analyzes three different types of powertrain concepts for efficient operation of a forklift truck. Starting from a conventional torque convertor transmission, hydrostatic transmission and a hydraulic hybrid transmission (Eaton architecture) are compared for their fuel economy performance. Eaton hydraulic hybrid system is seen to perform much better compared to other two architectures. Improved fuel economy is attributed to efficient engine operation and regeneration of vehicle kinetic energy during braking.

Global transport will continue to be powered largely by petroleum-based liquid fuels for the foreseeable future. However, the mix of transportation fuels required by the market as well as the composition of fuels will be changing. Gasoline octane needs to increase to enable more efficient spark ignition engines as well as the potential to develop Gasoline Compression Ignition (GCI) engines which can run on low octane gasoline rather than diesel. This presentation investigates the implications these changes in fuel mix and composition have on petroleum refining, one without and one with the possibility of producing a low octane gasoline for GCI engines.

CO2 emission legislation will remain one of the key drivers for future engine technology. Shell believes that between now and 2030 hydrocarbon based fuels could enable new credible, cost effective technologies to drive further improvement of the WtW CO2 footprint of light duty mobility. The longer term availability of liquid fuels plays a dominant role to assess the feasibility of Gasoline Compression Ignition concepts from an economic perspective and can become a key competitive differentiator for OEMs who are seeking to introduce new types of engines. In this presentation we aim to show pathways to a sustainable future energy supply and derive implications, opportunities and barriers for advanced Compression Ignition engine concepts.
