This estimate is uncertain since future fuel cell costs are unknown and cost savings from idling vary greatly across the truck fleet. The payback period is particularly sensitive to diesel fuel consumption at idle. Given the large potential environmental and economic benefits of fuel cell APUs, the...
At idle and light load conditions, spatial combustion is more likely, meaning that the fuel does not reach the walls of the combustion bowl, but burns in the space between the nozzle tip and the combustion bowl perimeter. In addition, the fuel concentration in the spray core is rather small...
Therefore, diesel air-fuel-ratios are typically from 100:1 or more (at idle) and roughly 40:1 to 30:1 at normal operation. Even the Audi LeMans racer runs no less than 19:1. Running anything greater than that results in prodigious plumes of black smoke, which “coaler...
THE STUDY OF POSSIBILITIES FOR REDUCING FUEL CONSUMPTION FOR NATURAL GAS ENGINE BASED ON DIESEL AT IDLE SPEED Diesel-to-natural gas engine conversion is an important economic task. In this modification the gas engine has some fundamental differences from the diesel... DV Apelinskiy,V Gusarov,V ...
The main determinants of the economic returns are the station use rates and the price of diesel fuel. Our analysis shows that battery-electric trains are cost-effective today if diesel-electric trains internalize the costs of environmental damages, even at battery prices of US$250 kWh–1 and...
Product name:KTA38 Diesel Engine;Fuel Consumption at Rated Speed:80.2gal/hr / 303.6 l/hr;Approximate Fuel Flow to Pump:141gal/hr / 533.7 l/hr;Intake Manifold Pressure:54in. Hg / 183kPa;Rated Engine Power:1193kW/895KW/1342KW;Rated Engine Speed:1800rpm/190
This method is known in engine building primarily as a means of increasing the efficiency of diesel engines at idle speed and small loads. It has been established that there is a decrease in the hourly fuel consumption to 33% of the rated effective power when engine cylinders are deactivated ...
Despite the disadvantages of higher noise (most apparent at idle) and higher cost, the diesel penetration into the light-vehicle and passenger-car markets has continued growing rapidly, especially in Europe where fuel prices are high and fuel taxation policies favor diesel. The requirement of lower...
