In order to improve the control precision of in-cylinder mixing and combustion process, and to avoid the engine power drop because of the port fuel injection mode, it becomes a tendency to inject gas fuel into cylinder directly, with the help of the high-pressure gas-fueled injection device.

Modelling Injection Valves from 3D to Real Time
IFAC Proceedings Volumes, 2000Abstract The increasing complexity of fuel injection systems has to be accompanied by modern design techniques, which allow to prototype and test in a virtual environment not only single components, but also their interaction with foreign domains. Nowadays, the design process results in a collection of models at different levels of abstraction, for ...

<div class="htmlview paragraph">A study to investigate the influence of fuel injection timing on exhaust emissions from a single-cylinder direct-injection spark-ignition (DISI) research engine was performed. Experimental results were obtained for carbon monoxide (CO), unburned hydrocarbon (HC), and oxides of nitrogen (NOx).

Valve gate locations and open timing for injection molding of an automotive instrument panel is to be determined to minimize the cavity pressure. To achieve design automation for obtaining the solution of this design problem, we first integrated MAPS-3D, a commercial injection molding analysis tool, to PIAnO, a commercial process integration and design

Experiments in Fluids, 1997
The performance and droplet characteristics of a sixteen-valve, four cylinder engine operating with combustion in one cylinder have been measured with part load, a speed of 1200 rpm and a stoichiometric mixture of gasoline and air. The indicated mean-effective cylinder pressure was found to be constant with initiation of injection from 150° to 630° of ...

A New Engine Control System Using Direct Fuel Injection and Variable Valve Timing
SAE Technical Paper Series, 1995<div class="htmlview paragraph">A new engine drivetrain control system is described which can provide a higher gear ratio and leaner burning mixture and thus reduce the fuel consumption of spark ignition engines. Simulations were performed to obtain reduced torque fluctuation during changes in the air - fuel ratio and gear ratio, without ...
