TL;DR: In this paper, the effects of fuel injection pressure on the exhaust emissions and brake specific fuel consumption (BSFC) of a direct injection (DI) diesel engine have been discussed, and the results confirmed that the BSFC, carbon dioxide (CO2), nitrogen oxides (NOx) and oxygen (O2) emission increased, smoke opacity, unburned hydrocarbon (UHC) and carbon monoxide (CO) emissions decreased due to the fuel properties and combustion characteristics of biodiesel.

11 Jul 2002TL;DR: In this paper, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from a damping chamber via damping throttle in an injection event reaches the fillingpath of the pressure booster pressure chamber via the damped path.
Abstract: A fuel injection system for an internal combustion engine including a fuel injector which can be subjected to fuel at high pressure and is actuatable via a metering valve device by which the pressure in a pressure booster control chamber is controllable such that the pressure in a pressure booster pressure chamber, defined by a pressure booster piston, that can be filled with fuel from the high-pressure fuel source via a filling path in which a check valve is disposed and that is in communication with an injection valve member pressure chamber, is increased by the pressure booster piston such that an injection valve member opens for injecting fuel, whereupon fuel is positively displaced out of a damping chamber via a damping path, in which a damping throttle is disposed. To assure stable injection performance, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from the damping chamber via the damping throttle in an injection event reaches the filling path of the pressure booster pressure chamber via the damping path.

TL;DR: In this article, an experimental study was conducted to evaluate the effects of using blends of ethanol with conventional diesel fuel, with 5%, 10% and 15% (by vol.) ethanol, on the combustion and emissions of a standard, fully instrumented, four-stroke, high-speed, direct injection (HSDI), "Hydra" diesel engine located at the authors' laboratory.

TL;DR: In this paper, the effects of oxygenated fuels in conjunction with single and split fuel injections were conducted at high and low loads on a Caterpillar SCOTE DI diesel engine, and the results indicated that the soot reduction due to the addition of oxygenate to the fuel is most effective in rich combustion as split injections are known to be effective at leaning-out the charge.
