Harry Nathaniel Allen of The New York Taxicab Company, who imported the first gas-powered New York City taxicabs from France in , borrowed the word "taxicab" from London, where the word was in use by early " Taxicab" is a compound word formed from contractions of "taximeter" and "cabriolet". "Taximeter" is an adaptation of the German word . Heavy-Duty Diesel Pickup Comparison Test: By the Numbers Ford, GM, and Ram have all significantly updated their heavy-duty pickup trucks. Popular Mechanics was .
Which produce less CO2, gas or diesel engines tell us that diesel produces less CO2 than gasoline powered cars. believe the past reputations about fuel economy and greenhouse gas emissions. Two vehicles, an experimental Oldsmobile diesel Cutlass and a Volkswagen diesel-powered Rabbit, were evaluated to determine their gaseous, particulate, smoke, odor, and noise emissions. For comparison, a Oldsmobile Cutlass powered by the CID gasoline engine and a liter gasoline fuel injected Volkswagen Rabbit (Calfornia version Cited by:
This paper addresses the relative fuel economy and emissions behavior, both measured and modeled, of technically comparable, contemporary hybrid and conventional vehicles fueled by gasoline, in terms of different driving cycles. Criteria pollutants (hydrocarbons, carbon monoxide, and nitrogen oxides) are discussed, and the potential emissions benefits of designing hybrids Cited by: 1. Clean diesel technologies have improved the quality of clean air emissions in diesel powered vehicles considerably in recent years. However, before you rush out and purchase a clean diesel Jetta or a bio-diesel powered car, there are some facts you should be aware of.

Comparison of fuel economy and emissions for diesel and gasoline powered taxicabs. Washington, D.C.: The Administration ; Springfield, Va.: National Technical Information Service [distributor], For gasoline vehicles, the label shows City, Highway, and Combined MPG (miles per gallon) values.
The Combined MPG value is the most prominent for the purpose of quick and easy comparison across vehicles. Some form of the miles per gallon metric has been on vehicle labels since Combined fuel economy is a weighted average of City and.
Simply, with respect to diesel versus gas mileage, there is no debate. Diesel has slightly higher emissions rates per gallon, but substantially better fuel economy.
Per joule of energy produced per gallon, gasoline is a far bigger culprit with respect to emissions, pollution, global warming, acid rain, and human, plant and animal toxification.
diesel fuel. The gasoline required was quantified by dividing the miles traveled by the average mileage per unit weight. This allowed us to scale everything down to the parts needed for one complete vehicle. We assumed batteries are made in China and shipped to San Pedro via large diesel cargo Size: 1MB.
As short comparison between emissions produced by gasoline and bioethanol, gasoline produces about CO2 kg/l while ethanol releases kg/l, which means it reduces CO2 emissions by 21 percent. 2 Emissions, Fuel Economy, and Fuel Consumption. The fuel economy (FE) and fuel consumption (FC) of diesel and gasoline vehicles are related to CO 2 emissions by the following expressions: The subscripts d and g denote diesel and gasoline, respec-tively.
The units for the terms in eqs 1 and 2 are as follows: g/km for [CO. The overall fuel economy and emissions results of all the buses were summarized in Table 4.
It should be noticed that the real-world cycles of the six tests were different as shown in Table 2, which might affect the fuel economy and emissions. The fuel consumption rates were calculated using carbon balance method as given in.
The time ratio Cited by: Fuel economy of the. to present Buyer's Guide to Fuel Efficient Cars and Trucks. Estimates of gas mileage, greenhouse gas emissions, safety ratings, and air pollution ratings for new and used cars and trucks.
Concerns regarding global warming have increased the pressure on automobile manufacturers to decrease emissions of CO2 from vehicles. Diesel vehicles have higher fuel economy and lower CO2 emissions than their gasoline counterparts. Increased penetration of diesel powered vehicles into the market is a possible transition strategy toward a more sustainable transportation by: Most governments of countries (or, in the case of the European Union, regions) with large auto markets regulate passenger vehicle fuel efficiency or CO 2 emissions (essentially the same thing, since CO 2 emissions are directly proportional to the amount of fuel consumed).
But they take differing approaches to designing regulations, and use different underlying drive cycles and. The emissions performance and fuel economy from three model year, 40 foot (13 meter) buses powered by John Deere hp ( kW), liter, six cylinder natural gas engines were.
The gas savings really is not there when you look at it from an energy cost standpoint. Fuel economy-wise though, hybrids blow gasoline cars out of the water. Diesel vs Hybrid. Diesel engines typically increase gas mileage by 30 to 35% over gasoline engines--about the same as hybrids.
So when it comes to fuel economy, they are actually fairly even. Gasoline-Fueled Hybrid vs. Conventional Vehicle Emissions and Fuel Economy The submittedmanuscripthaa been authored by a contractor of the U.S. Government under contract No.

Hergenrother, United States. Urban Mass Transportation Administration. Office of Bus and Paratransit Technology, and Transportation Systems Center (page images at HathiTrust). Comparing the fractions of emissions for both cases, we see that the USEPA predicted 62% and 38% of the on-road PM 10 emissions were from diesel and gasoline vehicles, respectively.
CARB predicted 33% and 67% of the PM 10 as coming from these diesel and gasoline vehicles, respectively. There are a number of assumptions in this type of by: Diesel vehicles have higher fuel economy and lower CO2 emissions than their gasoline counterparts.
Increased penetration of diesel powered vehicles into the market is a possible transition strategy toward a more sustainable transportation system. To facilitate discussions regarding the relative merits of diesel vehicles it is important to have Cited by: Comparison of Modern CNG, Die sel, and Diesel Hybrid-Electric Transit Buses 3 | Page Administration’s new model bus testing program.
For each bus fuel economy (miles per diesel gallon equivalent, MPDGE) was measured on seven different test cycles with average speed ranging from MPH to Size: KB. hybrid buses average month fuel economy was 34% to 40% better than the older diesel buses and 60% to % better than the CNG buses.
No emission measurements were made. Sixty-six diesel powered taxicabs and an equal number of gasoline powered cabs were operated formiles each in three taxicab fleets in New York City. Identical cabs were powered with either CID diesel engines or CID gasoline engines. Test results from all cabs were used to determine fuel economy and exhaust : K M Hergenrother.
In recent years concern about exhaust emissions from motor vehicles has been increasing. To combat this, the motor industry has been promoting the diesel car as cleaner than petrol cars, due to their greater fuel economy and reduced maintenance requirements.
However, diesel cars have very different emission characteristics, and an increase in. Gasoline & diesel 1 A Comparison of Two Gasoline and Two Diesel Cars with Varying Emission Control Technologies Swedish Environmental Class 1 diesel fuel .Fuel Economy of the Gasoline Engine book.
