That decision was supported by solid data including a detailed analysis of Polk County’s diesel versus gasoline operating experience that clearly illustrated gas engines were a better investment (see “Why Polk County Switched From Diesel to Gasoline Power,” from the March 2000 issue ofAutomotiv...
Meanwhile, Dennis O'Connor of Christopher Trucks has stated that the hallmark of diesel is the load-pulling truck due to their fuel efficiency.EBSCO_bspElectrical Wholesaling
" Jansen of Donlen advised. "The torque advantage of diesel engines is better suited for pulling heavy loads up steep grades. The relatively high-compression ratio necessary to ignite the diesel fuel (17:1 diesel versus 9:1 gasoline), allows the diesel engine to generate all its torque...
Gas turbine cogeneration systems: a review of some novel cycles Hence, cogeneration with gas turbines utilises the engine's relative merits and boosts its thermal efficiency. Thereby, the worldwide concern about the ... YSH Najjar - 《Applied Thermal Engineering》 被引量: 140发表: 2000年 A ...
It cites that natural gas has lesser greenhouse gas (GHG) emissions compared with diesel. However, a study by California Air Resources Board (CARB) reveals that natural gas is not always better than diesel because it has less production and refueling sites....
Biodiesel, GTL (gas-to-liquid) or synthetic diesel fuels will be seen in more applications. Fuel cell as a primary propulsion power (versus as an APU – auxiliary power unit) still faces significant technical and cost challenges for commercialization in the foreseeable future. Competition over ...
A couple of days ago, at the V5 diesel post, I got into a spirited debate about diesel versus gas engines. The issue was that every naturally-aspirated (non-turbo) car diesel engine I’ve ever encountered has a lower torque output than a comparable gas engine. I and so...

These meters use a light source and a photodetector to measure the opacity of the exhaust gas. The detailed experimental procedure is explained in the subsequent sections. 2.5. Design of Experiment At first, the engine was permitted to run with neat diesel up to a steady state condition for ...
Reithofer have admitted a breakdown in the exhaust gas purification of a diesel engine, but denied any intention. ‘We made a mistake a few years ago’, Krüger said on Thursday at the BMW annual general meeting in Munich. BMW had always claimed in the exhaust gas scandal, which was set...
