Book Description
The present study investigates the effects of various intake configurations on a firing single cylinder research engine. Eighteen different intake configurations were tested and modeled including a straight baseline case, tapers, varying inlet radii, bends, and S-bends. All of the intakes include a beilmouthed flange at the entrance and retain the same length to the beilmouth, transducer locations, and downstream diameter in an effort to identify the effect of the intake geometry only. An experimental study was conducted where each intake was instrumented with three pressure transducers. One of the pressure transducers was located near the entrance of the intake; the others were located downstream of the barrel throttle. Volumetric efficiency, brake power, and intake and exhaust pressures for each configuration are presented to determine the effect of each geometry on engine performance. Each intake configuration was modeled using a quasi-one-dimensional finite difference engine simulation code, MANDY. The volumetric efficiencies and pressures obtained experimentally are compared to the predictions to assess the code's ability to predict the effects of the various intake configurations on engine performance. Taper area ratios above 1.5 were found to have a detrimental effect on volumetric efficiency at high-speed tuning peaks. The inlet flow losses for the sharpest beilmouth studied (R1/D = 0.05) had a measurable negative effect on volumetric efficiency, while those of larger-radiused inlets were negligible. The flow losses associated with the bends and S-bends also had a detrimental effect on volumetric efficiency compared to the straight pipe. In general, MANDY showed a good agreement with the experiments for each intake configuration for both volumetric efficiency and intake pressure near the valves at the main tuning peak speeds.

Book Description
Various combinations of commercially available technologies could greatly reduce fuel consumption in passenger cars, sport-utility vehicles, minivans, and other light-duty vehicles without compromising vehicle performance or safety. Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle. The book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel. Because fuel consumption data indicate money saved on fuel purchases and reductions in carbon dioxide emissions, the book finds that vehicle stickers should provide consumers with fuel consumption data in addition to fuel economy information.
