By National Research Council, Division on Engineering and Physical Sciences, Board on Energy and Environmental Systems, Committee on the Assessment of Technologies for Improving Light-Duty Vehicle Fuel Economy

A variety of combos of commercially to be had applied sciences may tremendously decrease gasoline intake in passenger autos, sport-utility autos, minivans, and different light-duty autos with no compromising motor vehicle functionality or defense. evaluate of applied sciences for making improvements to mild responsibility motor vehicle gas economic climate estimates the aptitude gasoline discount rates and prices to shoppers of obtainable know-how combos for 3 sorts of engines: spark-ignition fuel, compression-ignition diesel, and hybrid. in response to its estimates, adopting the total blend of stronger applied sciences in medium and big automobiles and pickup vehicles with spark-ignition engines may lessen gasoline intake via 29 percentage at an extra price of $2,200 to the shopper. changing spark-ignition engines with diesel engines and elements might yield gas mark downs of approximately 37 percentage at an further rate of roughly $5,900 according to automobile, and exchanging spark-ignition engines with hybrid engines and parts would scale back gasoline intake by way of forty three percentage at a rise of $6,000 in line with automobile. The booklet makes a speciality of gasoline consumption--the quantity of gasoline ate up in a given using distance--because power discount rates are at once regarding the quantity of gasoline used. by contrast, gas economic system measures how a ways a car will shuttle with a gallon of gasoline. simply because gas intake facts point out funds stored on gas purchases and mark downs in carbon dioxide emissions, the e-book unearths that car stickers may still offer shoppers with gas intake facts as well as gasoline economic climate details.

The Chemistry and Technology of Petroleum

Refineries mustn't ever merely adapt to evolving environmental laws for cleanser product standards and processing, but additionally locate how one can meet the expanding call for for petroleum products,particularly for liquid fuels and petrochemical feedstocks. The Chemistry and know-how of Petroleum, Fourth variation deals a twenty first century standpoint at the improvement of petroleum refining applied sciences.

Planning and Integration of Refinery and Petrochemical Operations

Sincerely divided into 3 major sections, this useful booklet familiarizes readers with the realm of making plans in petroleum refining and petrochemical undefined, whereas introducing numerous making plans and modeling ideas encompassing unmarried web site refinery crops, a number of refinery networks, petrochemical networks, and refinery and petrochemical making plans platforms.

The certification test fails to capture the full array of driving conditions encountered during vehicle operations. 1 provides some of the reasons why the certification test does not reflect actual driving. Beginning with model year 2008, the EPA began collecting data on three additional test cycles to capture the effect of higher speed and acceleration, air-conditioner use, and cold weather. These data are part of air pollution emission compliance testing but not fuel economy or proposed greenhouse gas compliance.

Knock and pre-ignition are to be avoided, as they both lead to very high rates of combustion pressure and ultimately to component failure. While approaches such as turbocharging and direct injection of SI engines alter this picture somewhat, the fundamentals remain. CI diesel engines, however, are not knock limited and have excellent torque characteristics at low engine speed. In the European market, the popularity of turbocharged CI diesel engines in light-duty vehicle segments is not only driven by the economics of fuel economy but also by the “fun-to-drive” element.

Driver behavior. The unsteady driving characteristic of many drivers increases fuel consumption. • Fuel. The test fuel does not match current pump fuel. • Air conditioning. Air conditioning is turned off during the certification test. In addition to overestimating mileage, there is no regulatory incentive for manufacturers to increase air-conditioning efficiency. However, there is substantial market incentive for original equipment manufacturers both to increase air-conditioning efficiency and to reduce the sunlight-driven heating load for customer comfort benefits.
